Radcombobox in EditItemTemplate column - Selection out of range

Hi
I am making use of a Radcombobox inside a Radgrid during Edit mode. I get this problem when I have different values for the
DataValueField and DataTextField. When I make use of the same valeus for both, I don't get the error and the Radcombobox is geting populated.

    
            <telerik:RadComboBox ID="CbAircraftModelType" runat="server" Skin="Black"      
        
                                        SelectedValue='<%# Bind("modelTypeName") %>' EmptyMessage=" Select Aircraft Type"                                
        
                                        HighlightTemplatedItems="True" DataTextField="modelTypeName" DataValueField="modelTypeId"    
        
                                        EnableTextSelection="False" DataSourceID="SqlDataSource_AircraftType"      
        
                                        OnClientSelectedIndexChanged="cb_OnClientSelectedIndexChanged" />

I am making use of a SqlDataSource to populate the Radcombobox.

    
            <asp:SqlDataSource ID="SqlDataSource_AircraftType" runat="server"      
        
                                ConnectionString="<%$ ConnectionStrings:AvengeConnectionString %>"      
        
                             SelectCommand="select modelTypeName,modelTypeId from Avenge.dbo.AircraftModelType ">     
        
                        </asp:SqlDataSource>

I don't have any code for working with this in the code-behind.

This is the error that I am getting:

[Solved] Setting the SelectedValue property

I have an invisible field on a page that I populate with a reference ID. How do I get this value into a RadComboBox SelectedValue property at runtime so the combo box has the default (invisible field value) selected when the window comes up?

Thanks,

Error when RadComboBox posts back

Hello,

I reload the items within a RadComboBox using the client-side API. I'm not using the WS load on demand feature, but solely the JS api to add items to the combo. When the items are refreshed and a postback happens, I'm getting this error below. When it goes to load the combo client-state, an error occurs. We are using the last 2009 Q3 version.

Thanks.

System.NullReferenceException: Object reference not set to an instance of an object.

[Solved] Auto-Filtering on KeyUp

Requirements
RadControls version	2009.01.0311.20
.NET version	2.0
Visual Studio version	2005
programming language	C#
browser support	all browsers supported by RadControls

PROJECT DESCRIPTION

The project demonstrates on how to filter a grid automatically on typing every single letter into the filter textbox. For this purpose an 'onkeyup' client event is added to the filter textbox wherein filtering is performed and the unique name of the currently filtered column is stored into a hidden field. The filter textbox of the current column is focused after a filtering has been performed and the cursor position in the textbox is set by adding an 'onfocus' client event to the filter textbox of that column.

Duplicate X button behavior in javascript code

I need to Duplicate X button behavior in javascript code.

My domains are different so I'm getting an access denied message when using frameelement. But when I click on the X - it closes the window and works.

So, is there javascript code that does exactly what clicking the "X" button does?

Can non-DNN RadMenu use DNN datasource?

Telerik,

I have an interesting use case that may be more common than you expect: I have an existing ASP.NET 2.0 web application that I am adding a side-by-side DNN site for content management. Even though the DNN/content site and my webapp site are technically two different web sites, I want the user experience to be seamless.

This requires that the navigation menu in both the DNN site and the non-DNN web app site look and act identical. My initial implementation thought was:

DNN Site: use the included RadMenu to display the DotNetNuke nav menu data (easy).
Web App Site: use RadMenu with identical skinning, but somehow query the DNN SQL database as the RadMenu datasource in this non-DNN site.

Is there any way to accomplish this? If supported (or even if custom code could accomplish), you'd have one more buyer of your ASP.NET AJAX controls!

Many thanks for your input, of for input of anyone who's tackled a similar problem.
