Setting CssClass in UpdateCommand of RADGrid

[Jürg]

Hi

I have an ASP.NET page containing a RADGrid with an EditFormTemplate. In the UpdateCommand of the grid I do some validation stuff and I would like to assign a CssClass to all the fields of the EditFormTemplate containing invalid values.

The validation is working properly. However, I can't manage to assign the CssClass to the controls. My UpdateCommand reads as follows:

Protected Sub CompanyGrid_UpdateCommand(sender As Object, e As GridCommandEventArgs) Handles CompanyGrid.UpdateCommand
  Dim objEditedItem As GridEditableItem = CType(e.Item, GridEditableItem)
  Dim objTextBox As RadTextBox

  objTextBox = CType(objEditedItem.FindControl("txtCompanyname"), RadTextBox)
  If objTextBox.Text.Trim() = "" Then
    objTextBox.CssClass = "MandatoryField"
    e.Canceled = True
    Exit Sub
  End If

End Sub

The CSS file contains the following definition for the class MandatoryField:

.MandatoryField
{
    margin-left: 0em;
    border:1px solid #397D47;
    background-color:#F77A80;
    font-size: 1.0em;
}

After exiting the UpdateCommand function, the page is reloaded but the CssClass is not set to the fields in question. How can I achieve a visual marking of the fields with invalid values?

Kind regards

Hi Jurg,

Please try the following code snippet which works fine at my end.

VB:

Protected Sub RadGrid1_UpdateCommand(sender As Object, e As Telerik.Web.UI.GridCommandEventArgs)
    If TypeOf e.Item Is GridEditableItem Then
        Dim objEditedItem As GridEditableItem = DirectCast(e.Item, GridEditableItem)
        Dim objTextBox As RadTextBox = DirectCast(objEditedItem.FindControl("txtCompanyname"), RadTextBox)
        If String.IsNullOrEmpty(objTextBox.Text.Trim()) Then
            objTextBox.CssClass = "MandatoryField"
            e.Canceled = True
            Return
        End If
    End If
End Sub

CSS:

.MandatoryField
      {
          margin-left: 0em;
          border: 1px solid #397D47;
          background-color: #F77A80 !important;
          font-size: 1.0em;
      }

Thanks,
