combobox headaches Posted by njp at 7/22/2004 4:05:46 PM BlankHi,
So much struggle and wasted time (days). I'm having a terrible time getting

Dataset Copy method Posted by Gary Shell at 7/15/2004 1:28:18 AM Still fighting with why the EndCurrentEdit seems to clear the underlying
Datasets.Item collection when a exception is thrown, I thought of a

Binding to DataView.Count Bug? Posted by JorgenD at 7/7/2004 4:13:02 AM Hi.

dt.Columns.Add("Val",typeof(int));
DataRow row;
row = dt.NewRow();
row["Val"]=1;
dt.Rows.Add(row);
row = dt.NewRo...more >>
