Hello, I have the following strange problem: I have two ultragrid , one called "gr" and the other "theMultiSelectGrid". I start to databind the grid"gr" with an existing dataset, and then I iterate to make some changes.

If I put a messageBox after the first databingind, the operation works fine and the data gets modified during the iteration. But if I remove the MessageBox, the data do not get updated in the iteration.

What is going on? 

gr.DataBind(ds);

           // MessageBox.Show("XXX.");

            for (int i = 0; i <= theMultiSelectGrid.Grid.Rows.Count - 1; i++)

            {

                UltraGridRow drA = theMultiSelectGrid.Grid.Rows[i];

                string CoteA = drA.GetCellValue("Code").ToString();

                string AnneeA = drA.GetCellValue("Cat2").ToString();

                for (int j = 0; j <= gr.Grid.Rows.Count - 1; j++)

                {

                    UltraGridRow drB = gr.Grid.Rows[j];

                    string CoteB = drB.GetCellValue("Code").ToString();

                    string AnneeB = drB.GetCellValue("Annee").ToString();

                    if (CoteA == CoteB && AnneeA == AnneeB)

                    {

                 //specific code

                    }

                }

}
