    Hello,

    Is there a way to refresh the column footer when the data in the grid is changed by an outside source? For example, if there was a details drawer that opens on the gridline and has a text box that is bound to the same data as the parent grid cell?

    Hi,

    You can invoke the RadGridView.CalculateAggregates() method to achieve your goal.

    Hi,

    You should invoke it after the data in the grid is changed outside it.

    For example you can subscribe for the LostFocus event of the TextBox and update the aggregates when you click outside of the TextBox.
    For example:
    private void TextBox_LostFocus(object sender, RoutedEventArgs e)
    {
        this.Dispatcher.BeginInvoke(new Action(() =>
        {
     
        this.clubsGrid.Rebind();
        }
        ));
    }

    Then the aggregate result will be updated.
