Bug while scrolling within a datagrid?
Hi!
The point is that while scrolling within a datagrid, sometimes the gridloses focus with no reason because I was just scrolling.The class below simply illustrates this(while scrolling you'll get a message)
Thank you in advance.
ps: I'm using vs.net 2003.

dt.Columns.Add(dc);
for(int i = 0 ; i < 100; i++)

DataRow dr = dt.NewRow();
dr[0] = "row #"+i;
dt.Rows.Add(dr);
}
this.dg.DataSource = dt;
