I'm getting this error whenever I click a button on the page.

This only happens when you're running the aspx page through a windows forms application that has a browser control.
If I load this page directly from any normal browser it works fine.

Page is running:

    <script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js" type="text/javascript"></script>
    <script src="//netdna.bootstrapcdn.com/bootstrap/3.0.0/js/bootstrap.min.js" type="text/javascript"></script>
    <script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/jquery-ui.min.js" type="text/javascript"></script>

 

Any suggestions?

Hello Ian,

The problems is due to that the WebBrowser control renders the page in compatibility mode of Internet Explorer. As noted in the Browser Support page the compatibility mode is not supported by UI for ASP.NET AJAX anymore since it renders the page in IE7 mode and introduces a lot of compatibility problems including positioning of floating elements (it was supported back in 2008).

What you can try to resolve the issue is to:

Attached File : ex.png

telerik:RadGrid (ASP.NET Web)

I want to get the header name of the column clicked by the user with the mouse.

<ClientSettings EnablePostBackOnRowClick="true">  
<Selecting AllowRowSelect="true" /> 
</ClientSettings>   

 protected void RadGrid1_SelectedIndexChanged(object sender, EventArgs e)
        {
            var dataItem = gv.SelectedItems[0] as GridDataItem;
            if (dataItem != null)
            {
                var name = dataItem["ColUniqueName"].Text;
            }
        }
The above source code is not what I want.
Because the user specified ColUniqueName .
I want to automatically get the coordinates of Row and Column&Column HeaderName when the mouse cursor is placed on the Cell of RadGrid.
