How to use Regularexpressionvalidator in RadGrid control?

[Indranath]

Hi Guys,

How can I use regularexpressionvalidator in RadGrid control with <InsertTemplate> and <EditTemplate>. Is there any other alternative for this.

In case of regEx fail, I am able to display the '*' next to the control but not the message in ValidationSummary [rendering as display:none].

Thanks in advance.

-regards
Indra

Hello Indranath,

The following demo explains the flexible server-side validation mechanism of the RadGrid edit form. Check whether it helps you.

I too would like to know how to use a RegularExpressionValidator control on a GridBoundColumn ... is it possible?

Hi Peter,

Please try the following code snippet to have a RegularExpressionValidator for a GridBoundColumn.

C#:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
  if (e.Item is GridEditableItem && e.Item.IsInEditMode)
  {
   GridEditableItem item = e.Item as GridEditableItem;
   GridTextBoxColumnEditor editor = (GridTextBoxColumnEditor)item.EditManager.GetColumnEditor("ColumnUniqueName");
   TableCell cell = (TableCell)editor.TextBoxControl.Parent;
   RegularExpressionValidator validate = new RegularExpressionValidator();
   validate.ControlToValidate = editor.TextBoxControl.ID;
   validate.ValidationExpression = "Expression";
   validate.ErrorMessage = "Error Message";
   cell.Controls.Add(validate);
  }
}

Thanks,
Princy

I know it's been a couple of years but in bulk edit mode, this event is not being raised.

Hi Matt,

The following article shows how to use a custom validator in batch edit mode: https://docs.telerik.com/devtools/aspnet-ajax/controls/grid/data-editing/edit-mode/batch-editing/validation.

If using that approach + the latest version does not help, I advise that you open a ticket and send us a small mockup that shows the issue.
