[Solved] InPlace Edit Cancel/Udpate causing error

[Steven Black]

Hello,

I'm trying to put in-place editing into my grid.  When I click the Edit image, the grid is placed into Edit mode properly.  However, whenever I hit the Cancel or Update buttons I am getting an error "Failed to load viewstate.  The control tree into which viewstate..." (please let me know if you need the full error message).

My grid HTML looks like this:

                    <telerik:RadGrid ID="rgDetails" runat="server" GridLines="None" AutoGenerateColumns="false"
                        Skin="Office2007" AllowPaging="True" PageSize="15">

                        </FilterMenu>
                    </telerik:RadGrid>

My entire code-behind is as follows:

Imports THA
Imports Telerik.Web.UI

Partial Class EditRemittanceEntryDetail
    Inherits System.Web.UI.Page

    Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
        Dim intID As Integer = Request.QueryString("ID")
        txtRemittanceEntryID.Text = intID

        Call LoadRemittanceEntryDetail()
    End Sub

    Private Sub LoadRemittanceEntryDetail()
        Dim dl As List(Of THA.ContributionAccounting.RemittanceEntryDetail) = THA.ContributionAccounting.GetRemittanceEntryDetails(0, txtRemittanceEntryID.Text, Session("DB"))
        If Not (dl Is Nothing) AndAlso dl.Count > 0 Then
            rgDetails.DataSource = dl
        Else
            rgDetails.DataSource = vbNullString
        End If
        rgDetails.DataBind()
    End Sub

    Protected Sub rgDetails_CancelCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles rgDetails.CancelCommand
        e.Canceled = True
        Call LoadRemittanceEntryDetail()
    End Sub

    Protected Sub rgDetails_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles rgDetails.ItemCommand
        Select Case e.CommandName
            Case "EditBtn"
                e.Item.Edit = True
                Call LoadRemittanceEntryDetail()
        End Select
    End Sub

    Protected Sub rgDetails_UpdateCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles rgDetails.UpdateCommand
        e.Canceled = True
        Call LoadRemittanceEntryDetail()
    End Sub
End Class

As you can see I didn't even bother putting any code into my rgDetails_UpdateCommand event yet, although I envision updating my SQL Server database within this event before rebinding the grid.

Any help would be greatly appreciately.

I'm not sure if it's noteworthy or not, but this entire page is opened from a RadWindowManager and is basically a "pop-up" page.

Thanks.

I was able to figure this out.  I used the NeedDataSource event and removed my LoadRemittanceEntryDetail routine.  I also made a few other changes as well (i.e. removing the ItemCommand event because it wasn't needed).
