>Hi,

this.DeletedPersonRow = dts.Tables[0].Rows[pi];

just stores a reference to the row in the DataTable. When the row is deleted its ItemArray is no longer accessible. Try cloning the DataRow:

>this.DeletedPersonRow = dts.Tables[0].NewRow();
>this.DeletedPersonRow.ItemArray = dts.Tables[pi].ItemArray;

Thank you so much. Yes, now it works.
