Track newly added data rows in RadGridView

INTRODUCTION

When the user operates with RadGridView, he clicks on the 'Click here to add a new row' row and enters some data. Then, the user presses the Enter key to add the new row to the existing data rows (i.e. the new row is not anymore on the 'Click here to add a new row' row). The newly added row is by default located, according to row data and current grid sorting or grouping settings. It is often useful to track this newly added row to be able focus it or let the user manage it in some way.

PROBLEM

Currently, RadGridView does not implement this feature in the box and there is no dedicated event which will be fired in this scenario.

SOLUTION

Although there is no straightforward way to subscribe to such event, you can get the exact moment by handling two events  - CurrentRowChanged and RowsChanged:

When you start typing in the 'Click here to add a new row' row, the RowsChanged event is fired with an Add Action.
Then we take the item in the NewItems collection. Next, when you press Enter, CurrentRowChanged event is fired. If the OldRow is of type GridViewNewRowInfo (i.e. it was previously on the 'Click here to add a new row' row), we check whether the item from the NewItems collection is not null and whether its index is different than -1. If these conditions are true, this is the moment that we want to get - moving a new row from the 'Click here to add a new row' row to the existing data rows below it.

Below you can find projects in both VB.NET and C# demonstrating the approach.
