Good morning,

I've cerated a new solution in framework 4.0 where i have a page withis code ( see belowe):

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajaxToolkit" %><asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server"></asp:Content><asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server"><ajaxToolkit:ToolkitScriptManager runat="server" id="ToolkitScriptManager2"></ajaxToolkit:ToolkitScriptManager><asp:HiddenField ID="hidForModel" runat="server" /><ajaxToolkit:ModalPopupExtender ID="ModalPopupExtender2" runat="server" TargetControlID="hidForModel"
			PopupControlID="pnlpopup" CancelControlID="btnCancel" BackgroundCssClass="modalBackground"
			RepositionMode="RepositionOnWindowScroll"></ajaxToolkit:ModalPopupExtender><asp:Panel ID="pnlpopup" runat="server" Style="width: 400px; background-color: transparent;"><div class="boxPrincipale_area"><div class="boxtitolo_boxPrincipale_area"><div style="overflow: hidden; clear: left; padding: 2px"><div style="float: left; width: 335px; margin-top: 5px; text-align: left" id="divTitoloFinestraMsg"
							runat="server"><asp:Label ID="lblTitoloFinestraMsg" runat="server" Text="" Visible="true" CssClass="testoTitoloMsgFinestra"></asp:Label></div><div style="float: right"><asp:ImageButton ID="btnCancel" runat="server" ImageUrl="~/PRIVATE/img/chiusura_finestra2.png"
								OnClientClick="javascript: ModalPopupExtender2.Hide(); e.processOnServer = false; return false;"
								ToolTip="Chiudi la finestra" /></div></div></div><div style="width: 335px; padding: 12px;" id="divMessage2" runat="server" class="testoMsgFinestra"></div></div></asp:Panel></asp:Content>

Then the  web.config code ( see belowe):

But i see the error (see belowe)

Why i can't to use the ajaxToolkit:ModalPopupExtender with ToolkitScriptManager on Aruba server with hosting Windows?

<ajaxToolkit:ToolkitScriptManager runat="server" id="ToolkitScriptManager2"></ajaxToolkit:ToolkitScriptManager>

Can you help me?

My current environment is Microsoft.Net 4.5.2, Visual Studio 2013, AJAX Control Toolkit v15.1. Ever since I upgraded to AJAX Control Toolit v15.1 and use the asp:Scriptmanager instead of the old ToolkitScriptmanager, the tab panels in my tab container become invisible. I think an exception thrown by Javascript when the page is being rendered caused the problem but I don't know how to fix this. 

Any suggestion on where to look is deeply appreciated.

Here's an example of a simple page:

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="WebForm1.aspx.vb" Inherits="Edesk.WebForm1" %>

<%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="ajaxToolkit" %>
<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>

<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<ajaxToolkit:TabContainer ID="TabContainer1" runat="server">
<ajaxToolkit:TabPanel runat="server" HeaderText="Details" ID="TabPanel1" TabIndex="0">
<ContentTemplate>
<table><tr><td>Test details</td></tr></table>

</ContentTemplate>
</ajaxToolkit:TabPanel>
<ajaxToolkit:TabPanel ID="TabPanel2" runat="server" HeaderText="Scope">
</ajaxToolkit:TabPanel>
<ajaxToolkit:TabPanel ID="TabPanel3" runat="server" HeaderText="Approval">
</ajaxToolkit:TabPanel>

</ajaxToolkit:TabContainer>
<table><tr><td>Test table under tab control</td></tr></table>

</div>
</form>
</body>
</html>

When I run debug I get this error:

Unhandled exception at line 3803, column 12 in http://localhost:56421/ScriptResource.axd?d=LA2uNqtVhxzSGcXjgWiXWMzwtqbnPMUmRP9jH3h0X6l82MORXTdoPhq1uVWN6VYHPOyBjTaf96dObBwHQpWSfAWO9cGXljZJKqL2EtTfofM9x-QAHX3fvuZzmFwummfX2NiNhZ1WtVY-5aKut_Ye8i1-cxlSl5eUqSchmx80oaZ9HLdNmraaCLX7x8ky1_N80&t=7b689585

I want to modify the http request input filter stream in my HTTP Module via request filter. I am able to do as long as size of content is same or smaller. However if content size increases it start giving me exception. Is there anyone who has done the similar task. OR is it possible at all to modify/increase the size of request input stream in my HTTP Module via request filter

I have a problem with a gridview that sits on a tabbed panel, which contains an update panel. The grid displays items a client has purchased in the past, it links to the clientID label on the form, but the primary key is the linenumber.

I use the builtin update and everything work well, I was using the built in Delete (i.e. I write no code but it gets called) but wanted to add a confirmation of delete and that stopped working, so I used rowcommand to do the delete, it deletes the data fine, but when I rebind the grid and update the panel it does not show on the screen, if I force a refresh of the page the gridview then shows the correct date.

Here is the HTML portion of the code:

The the code behind for the rowcommand, it calls the objectdatasource directly using the keyfield and deletes the row then updates the grid and the updatepanel - but nothing happens, except the udpdateprogress shows for a while, showing the update event is triggered:

    protected void gvItems_RowCommand(object sender, GridViewCommandEventArgs e)
    {
      if (e.CommandName == "Delete")
      {
        ItemUsageTbl _ItemUsage = new ItemUsageTbl();
        _ItemUsage.ClientUsageLineNo = Convert.ToInt64(e.CommandArgument);
        _ItemUsage.DeleteItemLine(_ItemUsage.ClientUsageLineNo);

        gvItems.DataBind();
        upnlItems.Update();
      }
    }

I have three user controls. The controls are Window.ascx, Preview.ascx, Message.ascx. The Preview control displays in the Window's control iframe and the message displays on top of the preview.

When btnClose button in the message.ascx control is clicked, I need to close everything. How can it be done?

I tried registering Window.ascx in the Message.ascx then calling a public method from Window.ascx.cs with mpeNewWindowPopup.Hide(); But it did not work.

Any ideas?

Window.ascx

I have a Databound Listview in which there are some fields and a button id="button1". There is modalpopupextender outside the listview. I wanted to show the popup when button1 is clicked. The Problem is TargetControlID="Button1" for ModalPopupExtender is not recognized outside the listview. Please suggest.

Hi. I have only a TextBox and a DropDownlist on aspx-file. TextBox enabled property is false by default. Texbox is in the UpdatePanel. And also I'm using MasterPage, but TextBox and DropDownlist aren't on the MasterPage. 

 protected void Page_Load(object sender, EventArgs e)
    {

        if (IsPostBack && DropDownList1.SelectedIndex != 0)
        {
            tbAuto.Enabled = true;
            Button2.Enabled = true;
        }



    }

Using this code. I'm not only getting a textbox with enabled true, but also the same textbox with enabled false which was by default.

How to solve it?

Can you please also explain me, why is it so? 

I have a text box with an AutoCompleteExtender attached. I am trying to use data returned from a stored procedure as the data source for a web service that worked with the extender when I used a select statement instead of the SPROC. Initially the select simply looked for users names and the extender worked properly. However,  I want to  be able to type in a   name, city, or statename and have the extender display results for all three. Example:

PROCEDURE [dbo].[multisearch] 

	@item varchar(50)
	-- SET NOCOUNT ON added to prevent extra result sets from
	-- interfering with SELECT statements.
	AS
	BEGIN

	SET NOCOUNT ON;

	declare @srchitem table(
	item varchar(50)
)

Insert into @srchitem 
select fname +' ' + lname

from riders

Insert into @srchitem
select distinct  city
from address


Insert into @srchitem
select distinct  statename
from state

 Select * from @srchitem where item like @item +'%'
END

The stored procedure is fairly simple. If I execute the procedure in the SQL Management studio like

EXEC multisearch 'ken' I get a bunch of Kens and Kenneths and the state Kentucky so I think that the SQL is OKAY.

but when I try to execute from the app  (debugging) it stops before it finishes the code:

[WebMethod]
public List<string> GetItems(string prefixText)
{
    SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["BDUCConnectionstring"].ToString());
con.Open();
SqlCommand cmd = new SqlCommand();
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "[multisearch]";
//SqlCommand cmd = new SqlCommand("select riderid, dname from riders where dname like @name+'%'", con);
cmd.Parameters.AddWithValue("@item", prefixText);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);
int cnt = dt.Rows.Count;
List<string> items = new List<string>();

    for (int i = 0; i < dt.Rows.Count; i++)
{
    items.Add(dt.Rows[i][0].ToString());
    items.Add(dt.Rows[i][1].ToString());
 //Names.Add(dt.Rows[i][0].ToString());
  string sid = dt.Rows[i][0].ToString();

    
}
    return items;
}
}
When the code hits the ine 'da.Fill(dt);' 
it stops running and the last part of the code never runs.There are no errors it just quits. Here is the ASPX:

<asp:TextBox ID="tbSearch" runat="server" OnTextChanged="tbSearch_TextChanged" /><ajaxToolkit:AutoCompleteExtender ID="txtfind_AutoCompleteExtender" runat="server" MinimumPrefixLength="2" EnableCaching="true" 
                    CompletionSetCount="1" CompletionInterval="1000"  ServicePath="~/Mutts/WebService.asmx" 
                    Enabled="True" ServiceMethod="GetItems" TargetControlID="tbSearch"></ajaxToolkit:AutoCompleteExtender>

Anyone know what the problem is?

Hi.

I have this code

<asp:MaskedEditExtender runat="server" TargetControlID="tb_time" ID="meeHoraChegada"
     MaskType="Time" Mask="99:99" AutoComplete="false"></asp:MaskedEditExtender><asp:MaskedEditValidator ID="MaskedEditValidator2"  runat="server"
     ControlExtender="meeHoraChegada" ControlToValidate="tb_time"
     IsValidEmpty="True"
     InvalidValueMessage="The Time is not valid!"> </asp:MaskedEditValidator> 

When i start to enter the time, where i press a key it fill's the hour with the twice os the key value and in the next key press i get the same number twice.

For example i press 1 the hour stays with 11 and where i press the second digit value 3 i get 33 the result will be 11:33....

if i press 2 and 5 i get 22:55...

Any idea?

I have installed AJAX Control Toolkit from here: https://go.devexpress.com/AjaxControlToolkit_Website_Download.aspx

BUT, I can't find it in the Toolbox. I have looked at this page: https://ajaxcontroltoolkit.codeplex.com/wikipage?title=Step-by-Step%20Installation%20Guide&referringTitle=Documentation

The instructions says:

1) After the installation is over, create new ASP.NET Web Forms project in Visual Studio
2) To show the AJAX Control Toolkit controls in the Toolbox select any .aspx page in the Solution Explorer

BUT, my toolbox still looks the same. I don't find anything like "AJAX Control Toolkit v15.1".

When searching for the issue, there always the same suggestions of creating "AJAX Control Toolkit" in the toolbox manually and then find  some "AJAXControlToolkit.dll". I have searched for this file and can't find it. Still I have "AJAX Control Toolkit" installed.

I don't know why finding this "AJAXControlToolkit.dll" is constantly suggested, because it doesn't seems to be the official way of doing things. When looking at the step-by-step guide there isn't any line mention searching for any dll, so I don't know why this (misleading information) is suggested by others. I'm sure that if finding some dll was the way to go, then it would have been suggested in the step-by-step guide.

So does anyone have any REAL suggestions on how to get the "AJAX Control Toolkit" in the Toolbox?
As I understand, not every version have support for Toolbox integration, but I'm using Visual Studio Community 2015, so I should be good to go.

How do i use model popup to display server side message on data submission, example if a user wants to submit record to database , how do i use model popup to display "Data submitted successfully!", instead of using window popup like this:

                                                                                }
                                                                                else
                                                                                {
                                                                                    ScriptManager.RegisterClientScriptBlock(btnSave, this.GetType(), "alert", "<script>alert('Please quantity required is more than the stock, Stock is 1 or less than 1, update stock ... !!')</script>", false);
                                                                                }
                                                                            }

Hi
       I am learning using ajax control toolkit and I am trying to use Ajax control toolkit modal popup extender in one of my website. Modal popup is working fine however I am not able to get black background when modal popup is opened.

Here is my code:

<asp:LinkButton ID="LinkButton11" runat="server">Open Pop up</asp:LinkButton>

        <ajaxToolkit:ModalPopupExtender ID="ModalPopupExtender1" runat="server" PopupControlID="PnlPopup" TargetControlID="LinkButton11" CancelControlID="LinkButton12" />
        <asp:Panel ID="PnlPopup" runat="server" CssClass="message">
            <h3>It Popped Up Here is modal popup</h3>

            <asp:LinkButton ID="LinkButton12" runat="server">Close</asp:LinkButton>
        </asp:Panel>

While using Ajax control toolkit in my website and I have created Ajax control toolkit modal popup extender in my page.
Every thing is working fine but when I am pressing any button on page or selecting any dropdownlist page reloads and it shows My modal popup extender for few seconds. It disappears when page is completely reloads.

How to solve this issue?

I have created a JQuery accordion of which I’m trying to implement a Cascading DropDownList (4 DropDowns).

The initial dropdown is bound to a stored procedure in the Page_Load event. This populates and works fine.

The other 3 dropdowns are also connected through stored procedures and are placed in their own SelectedIndexChanged events. The first dropdownlist (Page_Load event) also has a separate SelectedIndexChanged event. None of these seem to actually be firing.

When I execute the stored procedures in MSSQL Management Studio they all output the correct result. However one thing I need to mention is the ID for each of the stored procedures is a varchar.

This is from an old, non-relational, single distinct table in a database and not how I would have done it. But it holds too much data to correct.  

I've cut the code down as there far too much for these pages

Hi

I have 2 gridviews inside a tabcontainer.

On page load i want to hide the tabcontainer and only show it after the user clicks a button and if the Dataset isn't empty.

However, I get the error below. If I show the tabcontainer at all times there is no error.

I read somewhere to maybe hide the tr instead but when i add runat=server to tr and give it id it's not recognised in codebehine.

Sys.InvalidOperationException: Could not find UpdatePanel with ID 'TabContainer1_TabPanelGeneral_upMaslulim'. If it is being updated dynamically then it must be inside another UpdatePanel.

Hi

      Is is possible to close Ajax control toolkit modal popup extender when user clicks outside the area of Ajax control toolkit modal popup extender.

Means when user clicks on the blank portion of page where Modal popup does not exists. (Like in Jquery lightbox)

Hi,

I have a webform with gridview  inside an updatepanel. I have a reset button that is placed also inside another updatepanel.

If the gridview is in edit mode and user clicks reset button and then the search button again then the gridview is shown in the state it was when reset button was clicked.

I need the gridview to be in the normal state without any row in edit mode.

In the reset button I have upGrid.Update() //upgrid is the id of the grid's updatepanel.

What am i doing wrong?

Thanks
