Based on customer feedback:

Input controls, namely RadTextBox and RadComboBox appear misaligned and slightly different in terms of metrics

**UPDATE**
As of 2016 R1 SP1, the inconsistencies have been targeted and fixed as a part of a broader story to unify the appearance of the various components.
NOTE: The changes apply only to Light-weight rendering

When binding a RadGrid (client-side) containing a GridTemplateColumn as described in various Telerik posts, binding for that column seems to work for the first few rows, then seems to stop producing the markup for the asp:Label within the ItemTemplate. Therefore, the remaining items in the grid are empty for that column. 

I have isolated the issue in the attached test files and provided a screenshot of the result.

We have used Telerik controls for ASP.NET AJAX on our email verification ASP.Net application running on Windows server 2008 with IIS 8 in implementing a progress bar which shows the progress of emails verified. However, we have observed that when the application is run via the local host ( http://localhost/appplication.aspx) the progress bar always displays. However, when we run the application through the URL (http://111.222.333.444/application.aspx), the progress bar do not appear. Please kindly look into this. 

When many RadHtmlCharts are present on the page (especially if their animation is turned on) this will decrease the rendering performance of the browser, especially in older browsers that are generally slow. 

The ability to start rendering one chart only after the previous one finishes rendering will improve this initial load.

This can be used only for animations to provide a visual queue (i.e. only have effect when Transitions=true).

When i try to perform filter, browser shows Server time out or at some times it will work after 5 mins. I have almost 25k records in the grid. Selection is working fine. Can any one help?

Regarding: Client-side Binding, Programmatic Binding

Attempted to perform Client-side Binding to reduce sort and filtering network traffic, using this example http://demos.telerik.com/aspnet-ajax/grid/examples/client/databinding/defaultcs.aspx#qsf-demo-source as the basis of my work.

I could not get the server-side public static GetData method to get invoked (and stop on a source code break-point), regardless what I tried.

However, I would get a runtime error immediately if I comment out the GetData method entirely.

The example code on the Telerik website cannot be downloaded and relies on a SQL Server database (cannot find a way of examining working code -- e.g. hardcoded values that are returned from GetData static WebMethod).

Would really like to get client-side data-binding working, but am unsure how to proceed.

NOTE: I also tried enabling DataBinding > EnableCaching, but break-point on NeedDataSource still got hit when gridview data was sorted or filtered (and I want sorting and filtering to occur client-side).

RadGrid version 2013.1.220.40

Both properties could be used in scenario when the control is bound with WebService. With assigning values directly to the aforementioned properties, you could omit specifying the Text and Value fields in the WebService, but only point the desirable parameters in the declaration of the control.

This could be very useful, especially when a custom class is used to populate the control in the WebService and if this class does not possess Text and Value fields.

The behavior is observable in the demos on Telerik's site. I am using ie10 with ie7 document mode.

currently migrating from SharePoint 2010 to Sharepoint 2013 facing issues as Radgrid control 2010.3.1109.35 not working

do we required to download new dll for sharepoint 2013?
does telerik radgrid support 4.5 framework?

I need a timeline AJAX component to "Visualize sequences of events in a user friendly manner" like this one in WPF : http://www.telerik.com/products/wpf/timeline.aspx

Do you plan to do that ?
Thanks

Other skins or browsers are working fine.  (Didn't test other IE Versions)
Bug appears also at the Demo site http://demos.telerik.com/aspnet-ajax/dropdownlist/examples/functionality/templates/defaultcs.aspx

See http://www.telerik.com/community/forums/aspnet-ajax/async-upload/null-exception-with-overridden-asyncuploadhandler.aspx

It would be helpful if the BarCode control could render DataMatrix barcodes

I am having an issue exporting data from a Radgrid when using a Radbutton. Even though I disable the AjaxManager from the code behind the Radgrid wound't export the data. However if I click the button a second time the export window opens, but the file doesn't contain any data. Is there some easy work around in order to fix this issue. If I completely remove the AjaxManager the problem is solved, but makes the usage and layout of the site bad. 

Here is my code...

ASPX:
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" >
    <ClientEvents OnRequestStart="RequestStart" OnResponseEnd="ResponseEnd" />
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="btn_Search">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="RG_DataList" LoadingPanelID="ContentLoadingPanel" />
                    <telerik:AjaxUpdatedControl ControlID="datePickersBar" />
                    <telerik:AjaxUpdatedControl ControlID="btn_Export" UpdatePanelRenderMode="Inline" />
                </UpdatedControls>
            </telerik:AjaxSetting>
            <telerik:AjaxSetting AjaxControlID="btn_Export">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
     </telerik:RadAjaxManager>

CS:
protected void btn_Search_Click(object sender, EventArgs e)
    {
        mergeDataTable();

    }

rotected void btn_Export_Click(object sender, EventArgs e)
    {
        RadAjaxManager1.EnableAJAX = false;

        RG_DataList.ExportSettings.ExportOnlyData = true;
        RG_DataList.ExportSettings.IgnorePaging = true;
       // RG_DataList.ExportSettings.OpenInNewWindow = true;
        RG_DataList.MasterTableView.ExportToExcel();
    }

Hallo Collegue,
It is possible to export only some columns of RadGrid to excel?

thanks,
