I have a master page that defines a RadAjaxManager :
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" DefaultLoadingPanelID="RadAjaxLoadingPanel1">
</telerik:RadAjaxManager>
and in my secondary page I have a button click handler that calls:
RadAjaxManager.GetCurrent(this.Page).Redirect("ManageGroups.aspx");
This fails with a null reference exception since GetCurrent returns null despite there being a RadAjaxManager on the master page. I've tried adding a RadAjaxManagerProxy to the secondary page but that doesn't seem to have any effect. So far the only way I've found to get round this issue is to create an extra RadAjaxManager on the secondary page which isn't very efficient.
This is in a project that was converted from .NET 3.5 to 4.0 just in case that helps point to the issue.
