Hello,
On the RadAjaxManager there is a method to set focus on a control after the ajax callback. (Setting Focus in Common Section on the examples site)

My question is how to do this if I use a RadAjaxManagerProxy. (my RadAjaxManager is on my Master Page, the Proxy on a usercontrol that refers the masterpage)

The .FocusControl is not available on the RadAjaxManagerProxy.

Thanks,
Nicolas

I have tried to display image on Grid using GridBinaryImageColumn but when run it display error:

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Parameter is not valid

I include here the my source code:

 

<

 

telerik:GridBinaryImageColumn DataField="CUST_LOGO" HeaderText="Image" UniqueName="Upload" ImageAlign="NotSet"

 

 

 

 

 

ImageHeight="80px" ImageWidth="80px" ResizeMode="Fit" DataAlternateTextField="CUST_NAME"

 

 

 

 

 

DataAlternateTextFormatString="Image of {0}">

 

 

 

 

 

<HeaderStyle Width="10%" />

 

 

 

 

 

</telerik:GridBinaryImageColumn>

 

In  my database the "CUST_LOGO" field sometime contain NULL value.

Hello,

We are currently working on a 3 tier asp.net web application, with .NET 3.5. We need to populate controls with a large amount of data.
I would like to know how to load the data in a listbox and combobxox in a fastest way, from the DAL to the UI. What are industrial best practices using latest and feasible technologies (ASP.NET MVC, Entity Framework, RadControls for ASP.NET AJAX, etc.)? 
Tell me if you need more information.

Thanks a lot in advance!

I am trying to use radwindow in the content page of .net web application. I am using this piece of code as suggested in documentation.

 function ShowExisting3() {
        var oWnd = $find("RadWindow1");
        oWnd.show();
    }

 <telerik:RadWindowManager ID="RadWindowManager1" runat="server">
           <Windows>
               <telerik:RadWindow
                   ID="RadWindow1"
                   runat="server"
                   NavigateUrl="http://www.google.com">
               </telerik:RadWindow>             
           </Windows>
 </telerik:RadWindowManager>
   
        <button onclick="ShowExisting3();return false;"  style="width: 190px">
           Show window (using show)</button>


oWnd contrains null value. any suggestions how to get reference to radwindow?

In your demos you show this using the client-side functionality but for the server-side you have to click a "select" column or a checkbox. I want the row to be selected server-side by clicking anywhere on the row. How do I do this?

Thanks.

Hello Team, I have a problem handling the sorting of my RadGrid that has a generic Dictionary as a DataSource, I bind the data handling the NeedDataSource event and works fine for binding the data and also for auto paging, I have enabled AllowSorting but when I click the only column there is I get "Sys.WebForms.PageRequestManagerServerErrorException: Cannot find column Value." following I share my declarative binding and the datasource handling on the code behind, I hope you can send some light to solve this issue.

At the aspx:

            <telerik:RadGrid ID="gvwTrainingProgramsRad" runat="server" AutoGenerateColumns="false"  AllowPaging="true" AllowSorting="true" >
                <pagerstyle mode="NextPrevAndNumeric" position="Top"></pagerstyle>
                <mastertableview width="100%" DataKeyNames="Key" AllowSorting="true" >
                    <Columns>
                        <telerik:GridBoundColumn AllowSorting="true" DataType="System.String" UniqueName="ProgramName" SortExpression="Value" HeaderText="Program Name" DataField="Value" />
                    </Columns>
                </mastertableview>
            </telerik:RadGrid>

At the CodeBehind:

        void gvwTrainingProgramsRad_NeedDataSource(object source, GridNeedDataSourceEventArgs e)
        {
             gvwTrainingProgramsRad.DataSource = GetPrograms();
        }

The GetPrograms() method returns a Dictionary<int, string>, like I said it works well for binding but not for sorting, what am I doing wrong?


Thanks for your help

I want to allow navigation of the treeview using the Up & Down keys on the keyboard.  So I followed the instructions shown here, specifically setting TabIndex="1" and AccessKey="T".  But unlike the demo on your website, it didn't change anything.

What more do I need to do?

Does PanelBar have ability to do RSS inside one of its node?

I want to do the consuming RSS where user can expand or hide it + other features with same ability (hide or expand).  I don't know that I pick the right tool to do this or not.  However, the panelBar has this ability to hide or expand.  But I am not sure the the panelbar can do the RSS with xml datasource.  Most of example of RSS consuming usually done by using data grid.  Is it possible to have data grid inside panel bar?  Please refer to the picture for more detail: http://img209.imageshack.us/img209/3775/65105342.jpg

Any advice would be very great.  Any sample of the work would be very awesome.  Thanks

Hello

I have the similar problem as mentioned in the thread http://www.telerik.com/community/forums/aspnet/grid/querystring-value-problem.aspx but I am unable to find the work around.

Basically when I Ajaxify my telerik grid with the RadAjaxManager and my page is using some QueryStrings then the Sorting/Paging of the grid stops working. I have the latest telerik dll version with me. What could be the problem?

Thanks
