AJAX Control Toolkit Resizable Control handle disappears behinde Control

Increase X and\or Y offsets:


<ajaxToolkit:ResizableControlExtender ID="ReportViewer_Main_ResizableControlExtender" runat="server" Enabled="True" TargetControlID="ReportViewer_Main" HandleCssClass="HandleHand" HandleOffsetX ="16" HandleOffsetY ="0" MaximumHeight="600" MinimumHeight="600">

Note: Microsoft Report Viewer did not scale well when vertically re-sized, therefore I limited the re-size horizontally!
