Selected, Active and AfterRowActivate
posted

Hello. I'm using a grid where I only need to manage one selected row at the time. So based in some reading I disabled row selecting (or set it as single row, I don't remember) and use ActiveRow.

Using the active row when I needed to know if it changed I used the AfterRowActivate event. This worked great until I realize that it only fires one some row is activated and not when the ActiveRow (property of the grid) change. The difference (pretty small) is that when a row is desactivated but no other is activated, the event is not fired.

I need to run some code when the ActiveRow changes (no matter if the new value is a row or null). How can I do? Is changing to selected row my only way?

Thanks,

Diego

    Hi Diego,

    So I guess the issue is that you are trying to detect when the ActiveRow is null? This should never happen, unless there are no rows in the grid at all. So I would think that using AfterRowActivate would be fine, as long as you also trap AfterRowsDeleted and check for grid.Rows.Count == 0.

    Are there other cases where you are getting no ActiveRow?
