dataGrid SelectedIndexChanged Method not available in Compact Framework

[C# Programming]

I have an application running on a PDA that currently uses the OnClick Event of a DataGrid to perfortm some functionality. I would like to have the same functionality run when the current row of my DataGrid is highlighted (by the user scrolling ro it instead of clicking on it). The method to use would seem to be OnSelectedIndexChanged but this does not seem to be available in the Compact Framework (3.5). I The OnGotFocus doesn't seem to be suitable either (I guesss that this is because it applies to the DataGrid itself and not the row). Can anyone suggest how I can get this to work. Note that I only want the event to fire when the user moves to the row and not when the grid is populated.

Thanks
