Hi,

I have a problem with the ImageMap when using the RadAjaxManager control.
I'm setting the width and height of the ImageMap using the RadAjaxManager control (within a radwindow control), and by doing that, the post back from ImageMap is not being caught by RadAjaxManager. All I try to do is to close the radwindow control and to navigate to another page.

My ImageMap control:

<asp:ImageMap ID="EntarnceImage" hotspotmode="PostBack"

onclick="RegionMap_Clicked" runat="server" >

</asp:ImageMap>

protected void RegionMap_Clicked(Object sender, ImageMapEventArgs e)

{

excuteWindowClose.Text = "<script type='text/javascript'>CloseAndNavigate('../../HomePage.aspx')</" + "script>";

}

:
By the way, If I setting the width and height of the ImageMap in other ways without using the RadAjaxManger, then the RegionMap_Clicked event will be fired.

Please, I need your help and explaination in order to solve the above problem.

Regards,
Bader

Hi,

I dont know how to use the updatepanel instead of the ajaxmanager in my case.
Below is the page code (This page is displayed within aradwindow control in maximized mode and the target is to stretch the imagemap ):
