I have a datagridview and a dev express gridcontrol in my window application (VS2005) ,
in my datagridview i have all the tables from my Database (SQL) . So when i double click a table in the datagridview all the data in that particular table is shown the gridcontrol.
My problem is that the devexpress gridcontrol does not clear the previous querry , so instead of showing only the selected table , it shows all the previous selected tables. I tried using :

C#

gridControl1.DataSource = null;
              gridView1.Columns.Clear();

but it does not work.
Can somebody please help me...I'm very new to C# so i ve no idea how to solve my problem.

Thanks :-)

Solution 2

SQL

while (gridView1.RowCount!=0)
            {
                gridView1.SelectAll();
                gridView1.DeleteSelectedRows();
            }
