Get aggregates from a group

This article shows how to obtain aggregates from a specific group in RadGridView.

In some cases when you define aggregates in RadGridView you need to access the ones in a specific group. You may do this very easily by iterating over the RadGridView groups, checking for a specific group key value and getting the aggregate result(s) as shown in Example 1.

Example 1: Obtaining Group Aggregates

private void Button1_Click(object sender, RoutedEventArgs e) 
    foreach (QueryableCollectionViewGroup item in this.radGridView.Items.Groups) 
        if (item.Key.Equals("24")) 
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) 
    For Each item As QueryableCollectionViewGroup In Me.radGridView.Items.Groups 
        If (item.Key.Equals("24")) Then 
        End If 
End Sub 

The QueryableCollectionViewGroup class represents a wrapper over an AggregateFunctionsGroup that allows for adding and removing of child items/groups. The snippet above simply checks for a key value equal to 24 and gets the formatted value of the first aggregate result.
