[Solved] Accessing Edit Template Controls After Set Telerik.Web.UI.GridItem.Edit = true

[cheburek]

Hello.
I have rad grid with templated columns (readonly and edit modes).
I set programmatically some row to edit mode base on my data on ItemDataBound event handler and then try to access control from row by its Id. I can't find control from EditTemplate but exist only from ItemTemplate

I explain on simple example. Here is a grid with templated column

<telerik:RadGrid runat="server" ID="weldsGrid" AllowPaging="True" AllowSorting="True"
            PageSize="20" GridLines="None">
            <MasterTableView AllowMultiColumnSorting="True" AutoGenerateColumns="False" EditMode="InPlace">
                <Columns>
<telerik:GridTemplateColumn DataField="Welder" HeaderText="Welder"
                        SortExpression="Welder" UniqueName="Welder">
                        <EditItemTemplate>
                            <asp:TextBox ID="WelderEdit" runat="server" Text='<%# Bind("Welder")%>'
                                ontextchanged="WelderTextBox_TextChanged" AutoPostBack="True" />
                        </EditItemTemplate>
                        <ItemTemplate>
                            <asp:Literal ID="WelderRd" runat="server" Text='<%# Eval("Welder") %>' />
                        </ItemTemplate>
                    </telerik:GridTemplateColumn>
</Columns>
            </MasterTableView>
            <ClientSettings>
                <Selecting AllowRowSelect="True" />
            </ClientSettings>
        </telerik:RadGrid>

ItemTemplate contains Literal control with Id = WelderRd   and EditItemTemplate contains control WelderEdit

Here I set one of rows to edit mode when I get data from database.

Private Sub weldsGrid_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles weldsGrid.ItemDataBound
    If (e.Item.ItemType = Telerik.Web.UI.GridItemType.Item OrElse _
        e.Item.ItemType = Telerik.Web.UI.GridItemType.AlternatingItem) Then

      If (e.Item.ItemIndex > -1) Then
        Dim row = CType(CType(e.Item.DataItem, DataRowView).Row, DSBiasStep.BiasWeldRow)
        SetControlsVisibility(e.Item, row)
      End If

    End If
  End Sub

Private Sub SetControlsVisibility(ByVal row As GridItem, ByVal data As DSBiasStep.BiasWeldRow)
    'set row to edit mode
    row.Edit = data.IsActive

    If Not data.IsIsAcceptedNull Then
      'even row in edit mode next row returns null
      Dim WelderControl= TryCast(row.FindControl("WelderEdit"), TextBox)
      If WelderControl Is Nothing Then
        ''''There is no reason to this but this is just example.
        'We always find a literal control even row is in edit mode
        WelderControl = TryCast(row.FindControl("WelderRd"), Literal)
      End If
      WelderControl.Enabled = CurrentUser.HasEditorRole
    End If
  End Sub

How can I get controls from EditItemTemplate after setting row to edit mode programmatically?

Hi Cheburek,

I have tried this code and it ran normally:

Protected Sub weldsGrid_ItemDataBound(ByVal sender As Object, ByVal e As GridItemEventArgs)
     If TypeOf e.Item Is GridDataItem AndAlso e.Item.IsInEditMode Then
         Response.Write(TryCast(TryCast(e.Item, GridDataItem).FindControl("WelderEdit"), TextBox).Text)
     End If
End Sub

I hope this helps.

Hi,

You can try out the following code to access the Controls in the EditITemTemplate:
vb:

Protected Sub RadGrid1_ItemDatabound(sender As Object, e As GridItemEventArgs)
    If TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode Then
        Dim editedItem As GridEditableItem = DirectCast(e.Item, GridEditableItem)

        Dim txtbx As TextBox = DirectCast(editedItem.FindControl("WelderEdit"), TextBox)
                '...
    End If
End Sub

You can also refer to the following online demo:
