Server side validation from RadGrid

[Andy Green]

Hi Team

I have a RadGrid with a Edit Form Setting of Template and a load of textboxes. Some of these have Requiredfield validator on them and this all works fine.

What I also need to do is a server side lookup on a value and not submit the data if that value exists. So I fill out my form, hit insert (its a new record) and if I single step the code it detects the duplicate value, but how do I then return to the radgrid, in insert mode, and show the error (I have a label control set to visible = false and want to show it.)

What is happening is the radgrid closes the form and I looses my data, and the label is never seen.

Hi,

Try setting the e.Canceled to true to cancel the closing of the Insert form on duplicate entry .

  protected void RadGrid1_InsertCommand(object source, GridCommandEventArgs e)
    {
      if("Duplicate exists")
        {
         e.Canceled = true;
        }

    }

How would I disable some of he text box control on edit, but have them available for insert.

I have the follwoing code but it disables the control all the time, I cant differentiate between edit and insert.

    Private Sub rgLocations_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles rgLocations.ItemCreated

        'disable the Location Code for edits as its the PK
        If (TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode) Then
            Dim UpdatedItem As GridEditableItem = DirectCast(e.Item, GridEditableItem)
            Dim LocationCodeAs TextBox = CType(UpdatedItem.FindControl("txtLocationCode"), TextBox)
            LocationCode.Enabled = False
        End If

    End Sub
