Sum (agregate function) on selected row in GridView

[skrec]

Hello,

I have this little question. I know how to apply sum function on all rows in GridView.

My question is: it is possible to apply sum function only on selected rows in GridView??

Thanks Petr.

Hi skrec,

If you know the type of your business object, which I am sure you do, you can do something like this by using LINQ and the Enumerable extension methods:

var sumOfSalaries = this.RadGridView.SelectedItems.OfType<FootballPlayer>().Sum(player => player.Salary);

I hope this helps.

Thanks. Petr
