I am receiving an exception whenever i peform any postback on a page with a grid.
I am adding the grid's column in code and also putting the whole grid into edit mode. The datasource is a datatable. I've been using the examples from the tutorials to get started. I also have 2 linkbuttons in the CommandItemTemplate. Whenever i click on either button, i never back it to the ItemCommand, instead i receive an exception:
DotNetNuke.Services.Exceptions.PageLoadException: Specified argument was out of the range of valid values. Parameter name: index ---> System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values. Parameter name: indexat System.Web.UI.ControlCollection.get_Item(Int32 index)at Telerik.Web.UI.GridTextBoxColumnEditor.LoadControlsFromContainer() ...
I can provide the rest of the stack trace if you need.

here is the ascx code:

Using this example, I was able to create a working CRUD interface using a SQL view; however, when I added calculated columns to the view, I received the following error.

Sys.WebForms.PageRequestManagerServerErrorException: Update or insert of view or function 'dbo.vwEnum' failed because it contains a derived or constant field.

Here's the table class definition.  CreateUser and UpdateUser are the calculated columns, and it works if they are removed.  Does anyone know how to prevent the calculated columns from being updated?

<telerik:RadPanelBar ID="rpbSections" runat="server">

<Items>

<telerik:RadPanelItem runat="server">

<Items>

<telerik:RadPanelItem runat="server">

<ItemTemplate>

<asp:GridView ID="gvPlanContents" runat="server" AutoGenerateColumns="True"

DataKeyNames="PlanContentID" HorizontalAlign="Center" Width="60%" ShowHeader="true"

EmptyDataText="No Data here">

</asp:GridView>

</ItemTemplate>

</telerik:RadPanelItem>

</Items>

</telerik:RadPanelItem>

</Items>

</telerik:RadPanelBar>

My code starts something like this:

List<PlanSections> mySections = PlanSections.GetAllPlanSections();
rpbSections.DataSource = mySections;

rpbSections.DataValueField =

"PlanSectionID";

rpbSections.DataTextField =

"PlanSectionName";

rpbSections.DataBind();

for (int i = 0; i < rpbSections.Controls.Count; i++)

 {

    int mySectionID = Convert.ToInt32(rpbSections.Items[i].Value);

   // what I need to know is, what code do I use to access the gridview.  I want to bind it for each
    // of its instantiations, by generating an object that depends on the value of MySectionID.
    // Where do I go from here?
}

Thanks!

Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. The same restriction applies if similar serialization is done by the custom session state store in 'Custom' mode.
