Back to my question: I have a GridDataBoundGrid bound to a datatable: dtblParts, and in it I display the following columns: CategoryID, PartID, Price and Quantity. Price column gets populated based on my selection in CategoryID and PartID. What I want now is that when I put in a value for Quantity a TotalPrice to be calculated and displayed somewhere on the form. To do that I do have a routine that checks the number of rows datatable has. Here is the problem: the number of rows is: 0. This is the way I initiate a "New part " operation: dtblParts.rows.Clear dtblParts.NewRow grdParts.DataSource = dtblParts grdParts.Refresh Why when I start editing Quantity column my datatable does not have any rows, because I just added one. You have to click on the next blank row and back in to get a row added to the datatable. (I check to rows.Count property)

Instead of dtblParts.NewRow, try this code. dtblParts.Rows.Add(dtblParts.NewRow)
