problem to add numerous rows in an unbound grid

Hi,

 I meet a performance problem when I try to add a large number of rows into my unbound grid. In fact I've got a loop where each time I insert a row into the grid's DataRowCollection (Rows):

for (i=0; i<60000; i++)

{

myTrueDbGrid.Rows.Add(myTrueDbGrid.newRow());

}

 The same problem appends with this method : myTrueDbGrid.AddRows(60000);

This operation take more than 10 minutes to success. I don't understand why because for the moment i just insert an empty row (newRow()).

Can you help me to improve this operation's performance. Thanks!

Ok I solve this problem suspending the binding before my loop and resume it after

myTrueDbGrid.SuspendLayout();

for (i=0; i<60000; i++)

{

myTrueDbGrid.Rows.Add(myTrueDbGrid.newRow());

}

myTrueDbGrid.ResumeLayout();
