You can edit the datarow directly from/through the datagridview. Once you get the hang of the datagridview - it is real nice. I have observed that the Cell End Edit event is the last event to fire when you leave a datagridview. If the row index is greater than the number of rows in the underlying datatable, I add a new datarow to the underlying datatable.

Accept Changes() End If End Sub e is the datagridview cell event arg for the Cell End Edit event of the datagridview.

Accept Changes() End If End Sub e is the datagridview cell event arg for the Cell End Edit event of the datagridview.

The trick is to add the row to the underlying data Table which is the datasource of the datagridview: Private Sub dgr Mod Sub Detail_Cell End Edit(By Val sender As Object, By Val e As System.

For this to work, you must be treating your data as immutable.

Updating via the row Node methods is supported in all row models.

Updating data via the row Node methods will refresh the grid for the required rows if they are showing, however it will not update the grids sorting, filtering or grouping if the new data impacts such.

The method // API method for updating data function update Row Data(row Data Transaction: Row Data Transaction): Row Node Transaction; // params for above interface Row Data Transaction // result for above interface Row Node Transaction The index to add is put in for historical purposes and should not be used.

If you want the grid to display in a certain order, you should set delta Row Data Mode=true and then set row data, which will maintain the row order while also working out the update, deletes and adds for you.
