[Solved] Unable to get handle to custom edit control

[Don Tompkins]

Hello,

I am using a grid control with a user control for editing the data. The Grid also allows multi editing and is using Paging.

I want to automatically save any changes that are in my edit control when someone navigates off the page or causes a postback. Here is the code I am using to gain access to my control for saving, but it always returns “Nothing.”

VB Code To Get Handle to UserControl:

        For Each gi As GridEditableItem In dgIVG.EditItems
            Dim MyUserControl As PatientDetails = CType(gi.FindControl("ctrlPatientDetails"), PatientDetails)
            If MyUserControl IsNot Nothing Then
                If Not MyUserControl.SaveData() Then
                    MyUserControl.MessageErrorVisible = True
                    Exit Sub
                End If
            End If
        Next

ASPX Code

    <telerik:RadGrid id="dgIVG" runat="server" Width="750px" AllowPaging="false" GridLines="None" AllowMultiRowEdit="false" Visible="false" Skin="Web20" >

                </ItemTemplate>
            </telerik:GridTemplateColumn>

            <telerik:GridTemplateColumn HeaderText="Insurance Plan">
                <ItemTemplate>
                    <asp:Label id="lblInsPlan" runat="server" Width="100px" Text='<%# GetFriendlyInsurancePlan(DataBinder.Eval(Container, "DataItem.InsPlan")) %>'></asp:Label>
                </ItemTemplate>
            </telerik:GridTemplateColumn>

        </Columns>
        </MasterTableView>
    </telerik:RadGrid>

Is there something I’m missing?

Thanks,

Hi,

Please try the code snippet below to access the UserControl in th edit form. You will need to access the EditFormItem for this:

VB:

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs)
    For Each editedItem As GridEditableItem In RadGrid1.MasterTableView.GetItems(GridItemType.EditFormItem)
    Dim userControl As UserControl = DirectCast(editedItem.FindControl(GridEditFormItem.EditFormUserControlID), UserControl)
    Next
End Sub

Thanks,

Princy
