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>

<telerik:RadMultiPage ID="RadMultiPage_Terminal_Edit" runat="server" SelectedIndex="0">

Code-Behind:

protected void Page_Load(object sender, EventArgs e)

{

if ((Boolean)Session["Page_First_Load"] == true)

{

Display_Reserved_Users(0);

}

Session["Page_First_Load"] = false;

}

.....

protected void Display_Reserved_Users(int rebuild)

{

SqlDataSource_Reserved_IDs = new SQL_Data_Source().getSQLDataSource();

SqlDataSource_Reserved_IDs.SelectCommandType = SqlDataSourceCommandType.StoredProcedure;

SqlDataSource_Reserved_IDs.SelectCommand = "OnTime_sp_Reserved_User_List";

SqlDataSource_Reserved_IDs.SelectParameters.Add("Param_Customer_ID_Ref", (string)Session["User_Belongs_To_Customer_Ref_ID"]);

SqlDataSource_Reserved_IDs.SelectParameters.Add("Param_Company_ID_Ref", (string)Session["User_Belongs_To_Company_Ref_ID"]);

RadGrid_Reserved_IDs.DataSource = SqlDataSource_Reserved_IDs;

if (rebuild == 1)

{

RadGrid_Reserved_IDs.Rebind();

}

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.
