If you dont want to show any validation errors and just want to block any non-numeral value then you can create the DataGridTemplateColumn and in CellEditingTemplate use the TextBox.

and in PreviewTextInput of the TextBox set e.Handled = true if value is other than integer:

       private void TextBox_PreviewTextInput(object sender, TextCompositionEventArgs e)
        {
            try
            {
                Convert.ToInt32(e.Text);
            }
            catch
            {
                e.Handled = true;
            }
        }
