Rad window not working in IE9

[Kannan]

Hi,

I am using Telerik dll version 2009.3.1103.35. I had a scenario to popup a window. So i used Radwindow and it was working good with IE7 & IE8. But all in a sudden it was not working for IE9. When i used to click the link to get the popup, the pages just refreshes instead of popup. Is this a telerik dll version problem or something else. Please give me some solution for this problem.

Thanks & Regards

Hello Kannan,

This issue is because you are using older version of the control, you need to upgrade at least to Q1 2011. Q1 2011 is fully compatible with IE9. Check the following KB article which explains more about this.
Updating RadControls for ASP.NET AJAX to another version or license.

Thanks

If you are unable (or unwilling) to upgrade to the latest Telerik release, try this IE9 workaround I found on Telerik's ASP.NET (not AJAX) forum:

Insert a meta tag that forces IE into IE 8 mode:

<meta http-equiv="X-UA-Compatible" content="IE=8" />

And something else important: this tag must appear early in the header, before any link or script tags.

If you wish to insert it programmatically you could do the following in your page's Load event handler:

' Try to force IE9 into IE8 Standards mode
Dim meta As New HtmlMeta()
meta.Attributes.Add("http-equiv", "X-UA-Compatible")
meta.Attributes.Add("content", "IE=8")
Me.Header.Controls.AddAt(0, meta) 'Must insert before any link or script tags!

Hope this helps!
