Edit form userControl

[Alexandre]

Im doing a prof of concept with the Telerik grid but i've hit a wall. I'm unable to access the userControl of the edit form. Here is a sample of my code.

ASPX

<form id="form1" runat="server">
    <telerik:RadScriptManager ID="ScriptManager1" runat="server" EnableTheming="True">
    </telerik:RadScriptManager>
    <div>
    </div>
    <telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False" GridLines="None">
        <HeaderContextMenu EnableTheming="True">
            <CollapseAnimation Duration="200" Type="OutQuint" />
        </HeaderContextMenu>
        <MasterTableView EnableHeaderContextMenu="True">
            <RowIndicatorColumn>
                <HeaderStyle Width="20px" />
            </RowIndicatorColumn>
            <ExpandCollapseColumn>
                <HeaderStyle Width="20px" />
            </ExpandCollapseColumn>
            <Columns>
                <telerik:GridEditCommandColumn>
                </telerik:GridEditCommandColumn>
                <telerik:GridTemplateColumn HeaderText="500226" UniqueName="ikSpecialty">
                    <ItemTemplate>
                        <cc1:Label ID="lblSpecialtyRad" runat="server" Text='<%# GetListString("specialite", "ikspecialite", Container.DataItem("ikspecialite"), "cspecial", True) %>'></cc1:Label>
                    </ItemTemplate>
                </telerik:GridTemplateColumn>
            </Columns>
            <EditFormSettings UserControlName="uscProcedure.ascx" EditFormType="WebUserControl">
                    <EditColumn UniqueName="EditCommandColumn1">
                    </EditColumn>
                </EditFormSettings>
        </MasterTableView>
        <FilterMenu EnableTheming="True">
            <CollapseAnimation Duration="200" Type="OutQuint" />
        </FilterMenu>
    </telerik:RadGrid>
    </form>

In the code behind, I am trying to access the user control but it always return 'nothing'.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        If Not IsPostBack Then
            SetDatasource()
            RadGrid1.DataSource = GetIntervAss()
        End If
    End Sub

Private Sub RadGrid1_NeedDataSource(ByVal source As Object, ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles RadGrid1.NeedDataSource
        RadGrid1.DataSource = GetIntervAss().DefaultView
    End Sub

 Private Function GetIntervAss() As DataTable
        Return DirectCast(Session("dsData"), DataSet).Tables("interventions_associees")
    End Function

' The MyUserControl is always = NOTHING
Private Sub RadGrid1_EditCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGrid1.EditCommand
          Dim MyUserControl As UserControl = CType(e.Item.FindControl(Telerik.Web.UI.GridEditFormItem.EditFormUserControlID), UserControl)
    End Sub

Can anyone help me on this?

Hi Alexandre,

EditCommand is too early to access the control. This command will tell the grid to open the edit form in the next lifecycle and you can access data user control in ItemCreated:

If TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode Then
    Dim MyUserControl As UserControl = CType(e.Item.FindControl(Telerik.Web.UI.GridEditFormItem.EditFormUserControlID), UserControl) 
End If

Kind regards,
