Object doesn't support property or method 'attachEvent'

[Ian]

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:

• Change the Document Mode of the WebBrowser to the latest version of Internet Explorer as explained at Controlling WebBrowser Control Compatibility, Use latest version of Internet Explorer in the webbrowser control, Web Browser Control & Specifying the IE Version and Configuring the emulation mode of an Internet Explorer WebBrowser control.
• Configure the WebBrowser control to use the Chrome engine: Use Chrome engine in WebBrowser control WinForms and Use chrome as browser in C#?
• Disable the Ajax on the page, load it in IE7 compatibility mode of Internet Explorer 11 and see what is the thrown error and if it could be handled.

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.
