I'm trying to delete and insert rows into the grids underlying datatable. When the item is at the top of the GDBG, the operation is quick, but when the item is at the bottom of the GDBG it is very slow (about 10,000 items in the grid).
The slowdown only occurs when the DataTable is bound to the grid, so I'm thinking this has something to do with the binding?
DataRow delRow = _dsItems.Tables.Rows.Find(updateID);
DataRow newRow = PostHelper.GetItem(_category,_itemDefinition,updateID);
