Hi.

I use NetAdvantage 2007.01.1071 

The problem with DateTime column (only Windows Vista).

When property Column.Nullable set to Infragistics.Win.UltraWinGrid.Nullable.Disallow and I choose today date from calendar,

say 23/12/2008, application crashes. It appeares, somthing is wrong with default Mask.

 Any other date, button 'today', choosing today date in non empty column works fine.

What can I do to solve the problem?

Thanks in advance.

 private void ultraGrid1_InitializeLayout(object sender, Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e)
        {
            e.Layout.Bands[0].Columns["PaymentDate"].Nullable = Infragistics.Win.UltraWinGrid.Nullable.Disallow;
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            try
            {
                DataTable dt = new DataTable();
                DataColumn dc;
                dc = new DataColumn("PaymentID", Type.GetType("System.Int32"));
                dt.Columns.Add(dc);
                dc = new DataColumn("PaymentDate", Type.GetType("System.DateTime"));
                dt.Columns.Add(dc);
                DataRow dr = dt.NewRow();
                dr["PaymentID"] = 1;
                dt.Rows.Add(dr);

                this.ultraGrid1.DataSource = dt;
            }
            catch
            {
            }
            finally
            {
            }
        }
    }
