How do you call the another updatepanel in the same tab?

Hi,

Please help. This is driving me nuts.

I migrated a web forms project from VS2008 .NET3.5 to VS2013 .Net3.5

I now find every time I edit the markup the designer.vb get's corrupted.

It get's changed from

    Protected WithEvents UpdatePanel1 As Global.Web.UI.UpdatePanel

to

    Protected WithEvents UpdatePanel1 As Global.AjaxControlToolkit.UpdatePanel

This does not happen on my colleague's machine when she edits the same file.

It also does not happen with all Ajax enabled projects on my machine

Here's a related post which seems unresolved

How do you call the same updatepanel in the same tab panel?By pressing a button onclick, it will add a updatepanel below, or do you have any other ways to create multiple updatepanel in the same form.

Hi ,

Is it possible to trigger the textchange event of a page from a modal popup?

Here's what I have User Control inside a Modal popup

GridView User Control is wrap with update panel so that I can update My TxtName

Passing Gridview SelectedItem to my TxtName.Text

    Protected Sub Select_Clicked(ByVal sender As Object, ByVal e As EventArgs)
        Dim currentrow As GridViewRow = TryCast(DirectCast(sender, Control).Parent.NamingContainer, GridViewRow)

        CType(Me.Parent.Parent.FindControl("txtId"), TextBox).Text = currentrow.Cells(1).Text
        CType(Me.Parent.Parent.FindControl("txtName"), TextBox).Text = currentrow.Cells(2).Text

        CType(Me.Parent.Parent.FindControl("MPE"), AjaxControlToolkit.ModalPopupExtender).Hide()

    End Sub

Value successfully pass but txtName.TextChanged event didn't fire 

<asp:UpdatePanel runat="server" ID="UpdateFace" UpdateMode="Conditional"><ContentTemplate><asp:TextBox ID="txtName" runat="server" ReadOnly="True" AutoPostBack="true" /></ContentTemplate></asp:UpdatePanel>

//Nothing happen even on debug mode

 Protected Sub txtName_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtName.TextChanged
//Some Operation
        Me.btnUpdate.Enabled = True
    End Sub

Hi

How can I fire the onfocus event of HTML editor.

Using AjaxFileUpload in WebForms targetting .NET 4.5.1, I get a javascript error only under a certain condition. This is the error:

throw "error raising upload complete event and start new upload"

And the condition:

Error only occurs when I include a web.config authorization element somewhere in the page's directory tree: deny users="?"

If I comment out the condition to restrict to authenticated users, AjaxFileUpload works successfully. If I apply this as a single condition in the authorization element (deny users), then the error is thrown.

Hi guys

I have an application that I am writting.

I use a javascript Loader which appears as a modal for when data is loading a bit slow.

It works great until I get to one page.

On this page I have a modal that loads on page load.

In the modal I have a series of search criteria.

When the Search button is clicked a Datagrid within the modal loads data.

To make this more dynamic and stop the datagrid repainting everytime a search is requested I have surrounded the controls on the modal with an AJAX Update Panel.

When the search button is clicked the Loader Modal appears as expected.

The only problem is that it doesnt then go away once the datagrid is loaded.

I also use masterpages and the code for the loader is on the masterpage.

I have tried using Javascript calls to close the loader but I cant get it to work.

I included a function that closes the loader when any ajax.complete action is detected but this doesnt work either.

Any suggestions??

Hello everyone and thanks for your help in advance.  I am completely new to the AJAX toolkit and want to use the ModalPopupExtender to edit a gridview rather than the typical inline method.  I am running into problems and amnot sure why.  The error I am receiving is:

Any help would be greatly appreciated.

I have added a CombineScriptsHandler in web.config and added a ToolkitScriptManager with the propertier ScriptMode="Release" CombineScripts="true".

I could see that its combining the scripts to one file CombineScriptsHandler.axd in the response, but for somereason, its not getting cached in the browser (with a 304 Not Modified), instead it issues a seperate request on every refresh and ends up with 200 OK response).

As per Stephen Walther's detailed documentation here , the combinedscript file is supposed to be cached - but unfortunately its not working for me.

Is there any additional steps I am missing here to have this combined script file cached? Please advice.

Hi

I have added AJAX to my web site and have looked at the various control extenders such as confirm button extender, modal popup extender, etc. They all seem to be linked to a specific control on the page – ie – a button, link button, etc. which the control name is know at design time.

What I want to do is using client side coding (java? Ajax?) have a confirming popup if the user selects the delete command (see the code snippet taken from a repeater control). Highlighted below that in red, you can see the name of the repeater linkButton changes thus none of the Ajax extenders seem to work.

Summarizing, if one of the delete linkButtons is pressed by the user, the Javascript should intercept the postback, create a popup that tests the user to ensure the delete command should be carried out, close the popup and allow the postback to proceed normally. If the user aborts the delete command, then the popup should close and no further action take place.

Is there somewhere I can find code such as this or have I misunderstood the Ajax entenders? Or can some Java guru write the code for me (I know very little about Javascript). (I have been using VB code behind but I think what I require should reside on the .aspx page)

Thanks in advance for your help and have a nice day.

Like many before me I have been trying to implement a tidy expandable/collapsible gridview where, for example, the grid initially shows a list of writers and on clicking on a suitable 'expand' button in a row the writer's works are dynamically retrieved from the database and displayed. Actually I have managed to get a reasonably tidy version to work using the Ajax Toolkit CollapsiblePanelExtender and DynamicPopulateExtender in combination with minimal additional Javascript. In case it is of any use to anyone, the key elements are as follows:

<asp:GridView runat="server" ID="Writers" DataSourceID="WritersDS" DataKeyNames="PersonID" PageSize='<%$ AppSettings: GridPageSize %>' ><Columns><asp:TemplateField ShowHeader="False" ItemStyle-VerticalAlign="Top"><ItemTemplate><asp:Image ID="ShowWorksButton" runat="server" /><ajaxToolkit:DynamicPopulateExtender ID="DPE" runat="server" PopulateTriggerControlID="ShowWorksButton" CacheDynamicResults="false" ClearContentsDuringUpdate="true" EnableViewState="False"
            ServiceMethod="GetWorks" ContextKey='<%# Eval("PersonID") %>' TargetControlID="WorksPanel" /></ItemTemplate></asp:TemplateField><asp:TemplateField HeaderText="writer" SortExpression="Surname" ItemStyle-Width="200" ItemStyle-VerticalAlign="Top"><ItemTemplate><asp:Label ID="hName" runat="server" Text='<%# Eval("Name")%>' /></ItemTemplate></asp:TemplateField><asp:TemplateField ItemStyle-Width="750"><ItemTemplate><asp:Panel ID="WorksPanel" runat="server" EnableViewState="false" style="height:auto;min-height:36px;max-height:124px;overflow:auto"/><ajaxToolkit:CollapsiblePanelExtender ID="CPE" ClientIDMode="Static" runat="server" TargetControlID="WorksPanel" ExpandControlID="ShowWorksButton" CollapseControlID="ShowWorksButton"
            ImageControlID="ShowWorksButton" CollapsedImage="~/images/expand.png" ExpandedImage="~/images/collapse.png"
            Collapsed="True" CollapsedSize="0" ExpandedSize="124" ScrollContents="True" AutoCollapse="False" AutoExpand="False" /></ItemTemplate></asp:TemplateField></Columns>

And in code behind:

<WebMethod()> _<ScriptMethod()> _
    Public Shared Function GetWorks(ByVal contextKey As String) As String
        Dim dal As New DAL
        Dim personid As Integer = CInt(contextKey)
        Dim html As StringBuilder = New StringBuilder
        html.Append("<table><col width='480px'</col><col width='70px'</col><col width='110px'</col><col width='35px'</col><col width='50px'</col>")
        html.Append("<tr><th style='text-align:left;'>title</th><th style='text-align:left;'>form</th><th style='text-align:left;'>genre</th><th>written</th><th>owned</th></tr>")
        Dim works As List(Of LiteraryWorkInfo) = dal.GetSelectedWorksByWriter(personid)
        Dim owned As String = ""
        For Each work As LiteraryWorkInfo In works
            html.Append("<tr><td><a href='workform.aspx?id=" & work.WorkID.ToString() & "'>" & work.Title & "</a></td><td>" & work.Form & "</td><td>" & work.Genre & "</td><td style='text-align:center'>" & work.Written & "</td><td style='text-align:center'>" & work.Owned & "</td></tr>")
        Next
        html.Append("</table>")
        Return html.ToString()
    End Function

It is also necessary to make the CPE IDs unique (it is probably possible to do this declaratively):

    Protected Sub WireUpWorks(ByVal s As Object, ByVal e As GridViewRowEventArgs) Handles Writers.RowCreated
        If e.Row.RowType = DataControlRowType.DataRow Then
            Dim cpe As CollapsiblePanelExtender = CType(e.Row.FindControl("CPE"), CollapsiblePanelExtender)
            Dim id As String = String.Concat("CPE", e.Row.RowIndex)
            cpe.BehaviorID = id
        End If
    End Sub

And like others I have found it necessary to add some Javascript to smooth the animation (why this could not have been the default or at least easily changeable I do not know) and to provide an accordion-like effect:

function pageLoad(sender, args) {
    for (num = 0; num < 20; num++) {
        var cpe = $find("CPE" + num);
        if (cpe) {
            cpe.add_expanding(accordion);
            cpe._animation._fps = 45;
            cpe._animation._duration = 0.4;
        }
    }
}
function accordion(sender, arg) {
    for (num = 0; num < 20; num++) {
        var cpe = $find("CPE" + num);
        if (cpe) {
            if (sender._expandControlID != cpe._expandControlID)
                cpe.collapsePanel(cpe._expandControlID);
        }
    }
}

All of this works surprisingly well, but there are some irritating aspects which I have not been able to fix. I have limited the maximum height of the works panel in order to prevent the overall height of the grid causing vertical scrolling of the page. But what I would really like is for the CPE ExpandedSize to reflect the actual height of the panel (i.e. equivalent to 'auto'). But this does not appear possible and I have had to set ExpandedSize to the same value as the panel's maximum height (not setting ExpandSize at all has the surprising effect of causing the panel to pop out to the full size of the actual content with no animation, completely ignoring the CSS on the panel itself). As a result, the panel always expands to this height even if there is less actual content. And what is even more irritating is that there is a 'disabled' vertical scrollbar in the panel even if no scrolling is required (and if I remove ScrollContents="True" from the extender then, perhaps less surprisingly, there is no scrolling, despite the panel CSS). What I do not know is whether this is a CSS issue or something to do with the extender. Either way, I would be grateful for any suggestions how to fix this.

Please Help Me!!!

Thank You,

Has anyone seen this error? I fell confident it's being caused by some Javascript issue. However, I have know idea where to even look. I have no idea what is causing this. No where...I repeat nowhere in my project am I using a parameter called "propName". On the page where this occurs I have an CollapsilePanel, an ImageButton, a GridView and a SqlDataSource which is using a stored procedure needing one parameter; an integer call "ctrl_id". I am passing this in a Session variable. The error appears in a popup window after I click th imagebutton. The image button simple makes the GridView visible. This error came out of the blue...I have run this page a hundred times and haven't changed anything for days and then all of a sudden I get this.

Any help would be greatly appreciated

I have a CheckBox with a ToggleButtonExtender to make it look nice.  If I click the image, it toggles and the appropriate image displays.  When a set the Checkbox1.Checked=true in code, the checkbox is toggled, but the image of the ToggleButtonExtender doesn't change.

How do you force the visual change when setting CheckBox1.Checked=true in code?

Hi,

I would like to show more information in my UpdatePanel. Instead of showing a simple "Please wait..." message, I would like to show which step it is currently at. Please refer to the sample code below.

I cannot seem to increment the step on the Tick event of the Timer control.

What is wrong?


Thanks,
ywb

Upgraded to latest Ajax release (Dec2013). My Website works fine on my pc, but when I move it to Godaddy it throws an error. If I use the asp scriptmanager page loads on website fine, but not with the ajax toolkit scriptmanager.a

Have spent two days researching and reading posts and I still cannot figure it out. I have listed the process below along with the error, masterfile, and config file. Can someone please tell me how I can correct this. Thanks, in advance.

Process:

-VS2010 selected create New Website (not project) 
-Installed Nuget Package Manager
-Installed AjaxControllToolkit
-Added ajax Tab to toolbox
-On ajax toolbox tab RightClick choose items and browsed to my website dir bin folder selected ajaxcontroltoolkit.dll

    Update-------

I got tired of trying to figure it out, so took the easy route, and went back to the last ajax version and it worked fine. Would still like to figure out at a later date, but back up and running now.

hello everyone,

i am building the employee portfolio where each employee enteres his/her data. at this stage am I building the image crop where an employee uploads image and then crops it. I am getting this error: Input string was not in a correct format. Could you please advice. thank you.

here is the code: 

{    public partial class Wizard : System.Web.UI.Page    {        String path = HttpContext.Current.Request.PhysicalApplicationPath + "images\\";        protected void Page_Load(object sender, EventArgs e)        {         }         protected void btnUpload_Click(object sender, EventArgs e)        {            Boolean FileOK = false;            Boolean FileSaved = false;             if (Upload.HasFile)            {                Session["WorkingImage"] = Upload.FileName;                String FileExtension = Path.GetExtension(Session["WorkingImage"].ToString()).ToLower();                String[] allowedExtensions = { ".png", ".jpeg", ".jpg", ".gif" };                for (int i = 0; i < allowedExtensions.Length; i++)                {                    if (FileExtension == allowedExtensions[i])                    {                        FileOK = true;                    }                }            }             if (FileOK)            {                try                {                    Upload.PostedFile.SaveAs(path + Session["WorkingImage"]);                    FileSaved = true;                }                catch (Exception ex)                {                    lblError.Text = "File could not be uploaded." + ex.Message.ToString();                    lblError.Visible = true;                    FileSaved = false;                }            }            else            {                lblError.Text = "Cannot accept files of this type.";                lblError.Visible = true;            }             if (FileSaved)            {                pnlUpload.Visible = false;                pnlCrop.Visible = true;                imgCrop.ImageUrl = "images/" + Session["WorkingImage"].ToString();            }        }         protected void btnCrop_Click(object sender, EventArgs e)        {            string ImageName = Session["WorkingImage"].ToString();            int w = Convert.ToInt32(W.Value);  //HERE I AM GETTING THE error: Input string was not in a correct format.            int h = Convert.ToInt32(H.Value);            int x = Convert.ToInt32(X.Value);            int y = Convert.ToInt32(Y.Value);             byte[] CropImage = Crop(path + ImageName, w, h, x, y);            using (MemoryStream ms = new MemoryStream(CropImage, 0, CropImage.Length))            {                ms.Write(CropImage, 0, CropImage.Length);                using (SD.Image CroppedImage = SD.Image.FromStream(ms, true))                {                    string SaveTo = path + "crop" + ImageName;                    CroppedImage.Save(SaveTo, CroppedImage.RawFormat);                    pnlCrop.Visible = false;                    pnlCropped.Visible = true;                    imgCropped.ImageUrl = "images/crop" + ImageName;                }            }        }         static byte[] Crop(string Img, int Width, int Height, int X, int Y)        {            try            {                using (SD.Image OriginalImage = SD.Image.FromFile(Img))                {                    using (SD.Bitmap bmp = new SD.Bitmap(Width, Height))                    {                        bmp.SetResolution(OriginalImage.HorizontalResolution, OriginalImage.VerticalResolution);                        using (SD.Graphics Graphic = SD.Graphics.FromImage(bmp))                        {                            Graphic.SmoothingMode = SmoothingMode.AntiAlias;                            Graphic.InterpolationMode = InterpolationMode.HighQualityBicubic;                            Graphic.PixelOffsetMode = PixelOffsetMode.HighQuality;                            Graphic.DrawImage(OriginalImage, new SD.Rectangle(0, 0, Width, Height), X, Y, Width, Height, SD.GraphicsUnit.Pixel);                            MemoryStream ms = new MemoryStream();                            bmp.Save(ms, OriginalImage.RawFormat);                            return ms.GetBuffer();                        }                    }                }            }            catch (Exception Ex)            {                throw (Ex);            }        }     }
