Radgrid disappears inside RadMultiPage when sorting

[Sunil]

Hi all,

I've a radgrid inside a radmultipage view. Everything works as it should apart from when I come to sorting. When I click on a sorting header, the radgrid disappears in the radpageview.... Sessionviewstate is enabled in my project... Below is the relevant code and code behind. Does anyone know why this is happening?

<telerik:RadTabStrip ID="RadTabStrip_Reserved_User_IDs" runat="server" Width="400px" ScrollChildren="false"
                SelectedIndex="0" Skin="Web20" MultiPageID="RadMultiPage_Terminal_Edit">
                <Tabs>
                    <telerik:RadTab Text="Reserved IDs: ">
                    </telerik:RadTab>
                    <telerik:RadTab Text="Activated IDs:">
                    </telerik:RadTab>
                    <telerik:RadTab Text="Reserve an ID:">
                    </telerik:RadTab>
                </Tabs>
            </telerik:RadTabStrip>

Hi Sunil,

I tried the scenario that you describe but I do not get that behaviour. I have attached a working project. Please check it and modify it in a way that the problem appears, so we can help you resolve it.

I have same issue. When session dead, if you click any column header, the whole grid will dispear. You need reload the page.
