Hello Milko,

Thank you for you answer.

I've created a button to delete the current row(s). Here's the code about it :

private void deleteButton_Click(object sender, EventArgs e)
{

         // Check if there are any selected rows.
         if (this.UltraGridExcludes.Selected.Rows.Count > 0)
         {
                 // Delete the selected rows by calling DeleteSelectedRows.
                 this.UltraGridExcludes.DeleteSelectedRows();
          }
          else
          {
                 // Show a message if there are no selected rows.
                 MessageBox.Show("There are no rows selected. Select rows first.");
           }
}

But it does not work. It always returns me the messageBox. I tried Ctrl+clic, Ctrl+A, Ctrl+Shif+clic, double clic, ... to select a row but it still not pass into the if statement. Maybe I'm doing something wrong ?

Edit: I do not have the little column on the left to see the current row selected with the little black arrow. That's maybe why I have always 0 row selected when I take a look to the count() result.

Edit 2: I add the colum for the row selection, and it's working, thank you Milko !
