Hi,

I am using @Ajax.Beginform in my View which is tightly bound to the ViewModel.

I've  @Html.ListBoxFor inside my form. I add and delete items from the listbox using jQuery. Now what I am want to achieve is that onpress of the submit button, it should send full data present in the listbox regardless of which are selected. Currently it sends the list to controller if  I select all the item in the listbox and press submit button. But I don't want to do that. Any idea as to how to achieve this?

Can it be sent as a form parameter. 

@using (Ajax.BeginForm("SaveTextComponent", "LoanFilterEditor", new{ param1 = Model.listBoxItem},  new AjaxOptions { HttpMethod = "POST", OnSuccess = "SUCCESS" }))

I try to accept the parameter in the controller like this

 public ActionResult SaveTextComponent(TextComponentViewModel model, List<SelectListItem> list)
{
}

But list is null.. Please help.

Hi,  I have reviewed all the posts having to do with my problem but have not found a resolution as  yet.

The website I have inherited has a seven-pane Accordion control that is loaded into an iframe element.  The iframe element sets the height of the accordion control dynamically with some JavaScript code that was obtained from the DynamicDrive website:  IFrame SSI script II- © Dynamic Drive DHTML code library (http://www.dynamicdrive.com).  Everything works fine with the Accordion control and its panes until a button is clicked somewhere (inside or outside of the Accordion) that causes a server post-back.  Then the height of the Accordion is clipped to whatever the height of the last pane expanded is.  Ithink it's the iframe element that is getting its scrollheight measurement from the height of whichever Accordion pane was last used and which is much shorter than the top Accordion pane (the default expanded pane on first load).  The iframe then sets the height limit for the whole Accordion control based on that, so that the content is clipped for all the panes, based on the height of the shorter panes. 

The Accordion control's property settings are as follows:

AutoSize = none (don't like scrollbars in the content panes)
RequireOpenedPane = false
SuppressHeaderPostbacks = true

I was wondering if a possible solution might be to add some code to the iframe JavaScript method that will check for a minimum scrollheight before setting the height of the iframe, so that the iframe height will beat least x pixels in height; maybe in the resizeIframe( ) function?  I'm not too strong in JavaScript so any help here would be appreciated.  Also, if there is a better solution, I am agreeable to that as well.  Setting a manual minimum height is not the best of all solutions, becuase most records viewed would probably be shorter than that and so the user would have to scroll down to see the other 6 collapsed panes.

Edit:  On further reflection, I think what I need most is to set the minimum height of the iframe to the total height of the Accordion with the first pane expanded , because that pane's content will always be the longest.  So how do I persist that value and pass it from the ASPX page where the Accordion sits to the Default.ASPX page where the iframe sits, and also to the MasterPage where the iframe's height is set in JavaScript?
End Edit

Here is the JavaScript that sets the height of the iframe element:

a.DiscoveryDate = CalendarExtender1.SelectedDate.GetValueOrDefault(); }

its getting saved as 1/1/0001 12:00:00 AM in the DB even after selecting the date. I see in debugging its getting the date into a.DiscoveryDate but CalendarExtender1.SelectedDate.GetValueOrDefault() returning deafult. Shouldnt I be using the extender there?

I cant use  a.DiscoveryDate = txtcalDiscoveryDate.Text; bz the error "cant implicity convert type "string" to System.Date.Time"

Any direction where I can check.

Hi, 

Guys I am stuck with this problem. I am creating dynamic extented sliders from code behind. And I am getting following error list, you can view it here : https://skydrive.live.com/redir?resid=4CFD9A87074E190C!1037&authkey=!AHw68oWfM08AzO4

In result of these I am unable to move the slider's handle in FireFox and Chrome but its works perfectly fine in IE and also it doesn't give errors in IE. 

This is the script that Ajax is generating: 

ys.Application.add_init(function() {
$create(Sys.Extended.UI.SliderBehavior, {"BoundControlID":"ctl00_ContentPlaceHolder1_gridRatings_ctl05_txtBoundCompetency37814","Maximum":5,"Minimum":1,"id":"ctl00_ContentPlaceHolder1_gridRatings_ctl05_seHBP37814"}, null, null, $get("ctl00_ContentPlaceHolder1_gridRatings_ctl05_txtCompetency37814"));
});

I think its thoes null values giving me error. Any help is much appriciated. 

Thanks,

Attiqe

I have a couple of controls on my page that when a selection is made from a drop down will either enable or disable the RequiredFieldValidator.  When I enter the screen and hit the button it displays the required text, but once I make a selection in the drop down the RequiredFieldValidator will no longer work.  Is there any issues with this?

Hi, i am a beginner at using gridviews and ajax control toolkit tools.

I am having difficulty setting the Modalpopup's TargetControlID with a LinkButton's ID which is inside a Gridview.

Error message :

The TargetControlID of 'ModalPopupExtender1' is not valid. A control with ID 'LinkButton1' could not be found.

 Source Codes : 

<asp:LinkButton ID="LinkButton1" runat="server" Text="Watch Online Now" OnClick="LinkButton1_Click"></asp:LinkButton>  (In a Gridview)

Hi all,

In my web page, there is a textbox control followed by an html editor.

When the page loads, the focus automatically sets to html editor.

After sets AutoFocus to false, IE sets the focus to the first control.

But in Chrome and Firefox it does not work.

Thanks in advance,

I'm very new to Asp.Net. I've come across handling ModalPopupExtenders with UpdatePanels and forcing ModalPopupExtender.Show() on to keep the modal window open previously. But I've only experienced it where the contents of the model popup have been coded within the same aspx form so far.

Now Im trying to cope with a modal popup extender with an IFrame that sources/parents another form. I've worked out how to keep the modal popup showing the IFrame, but the contents of the IFrame vanish immediately the popup pops up.

Is anybody able to help please?

(I've been using Rahman Masadur's very helpful article and "Expanse example" code so far at http://www.codeproject.com/Articles/34996/ASP-NET-AJAX-Control-Toolkit-ModalPopupExtender-Co and it's confused me because although he's been using ModalPopupExtenders his code seems so clean of update panels and he's done the same as me for using a 2nd form in an IFrame but his doesn't disappear)

Hi All,

I have a ModalPopUPextender in my page. ALso the Popup is supposed to be a Panel which has textboxes, Labels, Dropdowns. I also have a link button which I want to use to bring up the pop up. The problem is during design time when I mention the TargetControlID of the Link button, the ModalPopUpExtender disappears from the page. Also while runtime, I can't see the Link button also.

Thanks in advance.

I have a C# asp.net 4.5 web application.  It seems like I am getting 2 doctypes in my pages.  I have been trying to find ther source for a couple months, but cannot.  My master page has one html doctype on it - <!DOCTYPE html><html lang="en">.   But what I get on my pages looks like this:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"><!DOCTYPE html PUBLIC "" ""><HTML class=" js flexbox no-flexboxlegacy canvas canvastext no-webgl no-touch geolocation postmessage no-websqldatabase indexeddb hashchange history draganddrop websockets rgba hsla multiplebgs backgroundsize no-borderimage borderradius boxshadow textshadow opacity cssanimations csscolumns cssgradients no-cssreflections csstransforms csstransforms3d csstransitions fontface generatedcontent video audio localstorage sessionstorage webworkers applicationcache svg inlinesvg no-smil svgclippaths" lang="en">

I have searched the prject for !doctype and transitional and some other phrases but I cannot find where that HTML 4.0 is coming from anywhere.  It is really driving me nuts.   Has anyone else ever had this problem?

Thanks,

Hello: I have a web app with a formview control that has an ajax combobox in it:

<%--     AJAX COMBO BOX CONTROL:--%><asp:ComboBox ID="ddCompanyName" DropDownStyle="Simple" AutoCompleteMode="Append" runat="server" TabIndex="1"  DataSourceID="SqlDataSourceCompanyName" DataTextField="companyname" DataValueField="companynameId" SelectedValue='<%# Bind("companyname")%>'></asp:ComboBox><%--     END AJAX COMBO BOX CONTROL:--%>

I need to set the focus on this control when the page loads. I have tried to do it on the server side of my code:

 Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
        If Page.IsPostBack Then
        Else
           ScriptManager1.SetFocus(MainContent_frmCustomerInformation_ddCompanyName_ddCompanyName_TextBox.ClientID)
        End if
    End Sub

But it's not happy with my choice of client ids. to find what it was, I was running the page and viewing the source.

Am I on the right track here?

thank you for your help.

Hello: I have a form that has an Ajai combobox control on it. This control, is populated by a dataset:

<%--     AJAX COMBO BOX CONTROL:--%><asp:ComboBox ID="ddCompanyName" DropDownStyle="Simple" AutoCompleteMode="Append" AppendDataBoundItems="true"  runat="server" TabIndex="1"  DataSourceID="SqlDataSourceCompanyName" DataTextField="companyname" DataValueField="companynameId" SelectedValue='<%# Bind("companyname")%>'><asp:ListItem Text="Select" Value="" /></asp:ComboBox><asp:RequiredFieldValidator ID="reqCompanyName" runat="server" ControlToValidate="ddCompanyName" InitialValue="" Display="None" SetFocusOnError="true" ErrorMessage="Please select or enter Customer Name." /></td><%--     END AJAX COMBO BOX CONTROL:--%>

And in addition to it being populated by a dataset, I wanted to add item "Select" so that it appears at the top of the list and displays when the page loads; In my code above, I attempted to do this by adding this line:

<asp:ListItem Text="Select" Value="" />

however, when the page loads, the combo box appears blank until you click on it; that's when you see all the values in the database and it places "Select" into the mix in alpha order.

How can I make it so that "Select" appears at the top of the items. Also, how can I make "Select" appear in the box when the page loads?

thank you for your help,

Problem:
both the pages works absolutely fine when i run them individually. But when i start from "index.aspx" page and it generates result page with the help of ajax, the "result.aspx" page doesnt works correctly. Result.aspx have java script functions which are not working within ajax generated div. Grid is not shown.

Please suggest any help..

I have 2 ajax modal popups (I've omitted most of the code), when I close them I want to rebind the page behind which contains a datagrid. I have tried trying to trap the postback control and rebinding only when that control is listed as there are other postback controls on the page, but it's not working.  Any help would be greatly appreciated...
