UltraGrid doesn't refresh after setting DataSource
posted

Hi,

In winforms, I set datasource on a UltraGrid from DataSet with only 1 table. 

The Grid is OK, data are well displayed. 

When DataSet changes (Stored procedure with parameter), i reset the DataSource but the Grid doesn't change ! 

ultraGrid.Refresh() doesn't refresh anything. I tried manything ...

if (ds != null)
{
ds.Tables.Clear();
ds.Clear();
}
if (ds2 != null)
{
ds2.Tables.Clear();
ds2.Clear();
}

ds2 = Library.BLL.GetCRA(out error, dateSelect);

ds.Tables.Add(ds2.Tables[0].Clone());

for (int x = 4; x < ds.Tables[0].Columns.Count; x++)
ds.Tables[0].Columns[x].DataType = typeof(int);

foreach (DataRow dr in ds2.Tables[0].Rows)
   ds.Tables[0].ImportRow(dr);

grdCRA.DataSource = ds;
grdCRA.DataBind();
grdCRA.Refresh();

    Hello UCF_user,

    Thanks for attached code. Could you please verify (using a break point or debug message) that your ds contains data after changes through stored procedure. After that you could try one of these options below:

     

    Option 1: Please try to call :

    this.grdCRA.Rows.Refresh(Infragistics.Win.UltraWinGrid.RefreshRow.ReloadData, true);

     

    Option 2: Maybe you could try to set:

    grdCRA.DataSource = Null;

    grdCRA.DataSource = ds;

    Please let me know if you have any questions.
