Selecting all rows in a group

[Nirph]

Hello,

I have a RadGridView bound to a CollectionViewSource. The items in the collection view are sorted by Group Name (e.g "Group 1", "Group 2", etc...).

What is the best way to select all the items (based on group) when a user selects a single row? 

Thanks!

Hi Nirph,

You may handle the SelectionChanged event as follows:

private void playersGrid1_SelectionChanged(object sender, SelectionChangeEventArgs e)
        {
            var lastItem = e.AddedItems.LastOrDefault() as Player;

            if (this.playersGrid1.Items.Groups != null && lastItem != null)
            {
                foreach (IGroup group in this.playersGrid1.Items.Groups)
                {
                    var items = group.Items.Cast<Player>();
                    if (items.Contains(lastItem))
                    {
                        this.playersGrid1.Select(items);
                    }
                }
            }
        }
