Refreshing Problem

[arvind]

Hai,
I have a GDBG and and a DataTable is set as the dataSource for that grid .
The dataTable is loaded with data and I want to make the values of all the cells to blank,
So I have written
this.grid.BeginUpdate();
foreach(DataRow row in dataTable.Rows)
{
row["ColumnName"] = DbNull.Value;
.
.
.
}
this.grid.EndUpdate();

After there is a refreshing problem happening.

You should check if there are any exceptions being thrown from this code (as might be the case if this column in your DataTable does not allow nulls).

If there are no exceptions being thrown, then after this.grid.EndUpdate, you would have to call this.grid.Refresh (or RefreshRange) to tell the grid to repaint itself to show the changes you have made.

Hai ,
I don''t have any exception in any of the columns,One column''c Cell type is DateTime.
If I take out the BeginUpdate() and EndUpdate() ,then I can see the rows becoming empty.

Leave your code the way you have it, but after grid.EndUpdate(), add grid.Refresh();
