Find a control of an edit form in item command event

[William]

Hi,

I have a grid with an edit form with textboxes that I need to disable based on a button that is clicked in the form. I'm wondering if there is a way to find the textboxes in the itemcommand events that get triggered by the buttons?

I've been trying to use something like:

 

Private Sub RadGrid2_ItemCommand(ByVal source As Object, ByVal e As Telerik.WebControls.GridCommandEventArgs) Handles RadGrid2.ItemCommand

 

 

If e.CommandName = "TimeInOutTextboxes" Then

 

 

Dim editedItem As GridEditableItem = CType(e.Item, GridEditableItem)

 

 

Dim txtTimeIn As TextBox = DirectCast(editedItem.FindControl("txtTimeIn"), TextBox)

 

txtTimeIn.Enabled =

False

 

 

End If

but an error is thrown at "txtTimeIn.Enabled = False" because the control is not being found

Thanks

Hi William,

Try the following code snippets and see whether its working fine for you.

VB:

Protected Sub RadGrid1_ItemCommand(ByVal source As Object, ByVal e As GridCommandEventArgs)
    If e.CommandName = "TimeInOutTextboxes" Then
        Dim editedItem As GridEditableItem = DirectCast(e.Item, GridEditableItem)
        Dim txtTimeIn As TextBox = DirectCast(DirectCast((editedItem), Telerik.Web.UI.GridDataItem).EditFormItem.FindControl("txtTimeIn"), TextBox)
        txtTimeIn.Enabled = False
    End If
End Sub

Thanks,
Shinu.

Thanks a lot Shinu, but I'm getting an error in this line?:
DirectCast(DirectCast((editedItem), Telerik.Web.UI.GridDataItem).EditFormItem.FindControl("txtTimeIn"), TextBox)

The error is :
'Telerik.WebControls.GridEditableItem' cannot be converted to 'Telerik.Web.UI.GridDataItem'.

Thanks again,
 William

Hi William,

Try the below code snippets for accesing the textbox inside form template.

VB:

Protected Sub RadGrid1_ItemCommand(ByVal source As Object, ByVal e As GridCommandEventArgs)
    If e.CommandName = "TimeInOutTextboxes" Then
        Dim editedItem As GridEditableItem = DirectCast(TryCast((e.CommandSource), Button).NamingContainer, GridEditableItem)
        Dim txtName As TextBox = DirectCast(editedItem.FindControl("txtTimeIn"), TextBox)
    End If
End Sub

Thanks,
Princy.

Hello Srinivas,

Here is the sample code in c#.
c#:

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
{
 if (e.CommandName == "TimeInOutTextboxes")
  {
    GridEditableItem editedItem = (GridEditableItem)((e.CommandSource) as Button).NamingContainer;
    TextBox txtName = (TextBox)editedItem.FindControl("txtTimeIn");
   }
}

Here is the link for code converter.
