Hi,

Could you temporarily disable any AJAX on the page if present (RadAjaxManager, RadAjaxPanel, UpdatePanel, etc.) and enable your script debugger (FireBug or F12) to see whether there are any script or server errors interfering?

Does the RadButton work if you remove the confirmation logic? I suggest that you examine the following live sample, which demonstrates how you can achieve confirmation using RadButton:
http://demos.telerik.com/aspnet-ajax-beta/button/examples/confirm/defaultcs.aspx

Hope this helps.

Hi,

My question is 'PostbackUrl' block, It is no confirm logic.

<telerik:RadButton ID="Button1" runat="server" Text="Browse"

ToolTip="Browse"

CommandName="BrowseCommand"

CommandArgument="<%# Item.Id %>"

PostBackUrl="~/SurveyTest/at telerik forum question/E2.aspx">

</telerik:RadButton>

Hello,

To resolve the issue, you need to exclude the button when initiating a navigation to another page. Similar to this approach:
http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/ajaxified-radgrid/what-you-should-have-in-mind/export-from-ajaxified-grid

You can also check the following articles:
http://docs.telerik.com/devtools/aspnet-ajax/controls/ajax/how-to/exclude-controls-from-ajaxifying
http://docs.telerik.com/devtools/aspnet-ajax/controls/ajax/how-to/redirecting-to-another-page

I've created a sample RadGrid web site using the provided code snippets to demonstrate that the suggested approach should work as expected. Please run the attached application and let me know if it helps you.
