[Solved] RadGridView Grouped Row Selected Event

[Paul]

Is there an event that is fired when a user selects a grouped row? I need to update a report outside the grid that shows summary information specific to a selected grouped row. I searched through all available events and even tried to modify the GroupRowStyle template with no success.

I appreciate all your help.

Hello Paul,

Could you clarify a bit? Which row should be considered as select? A group that has its header clicked or any group that has just been expanded?

Kind regards,

Thank you for your reply.

I need to know when the Group Row is selected. In my case, when the row is clicked by the user -- selected -- the group row expands to show the underlying records. To clarify, the group row is the row which has the group expander and group aggregates as defined at the bottom of this page http://www.telerik.com/help/silverlight/gridview-visual-structure.html. I need to know when the user selects the row and some indication as to what aggregates are a part of that grouping.

Thank you for your time.

Hi Paul,

We currently do not have events that signal which is the selected group but most probably we will such events in the near future. In the mean time you can use the following workaround:

public MainPage()
{
    InitializeComponent();

    this.playersGrid.AddHandler(FrameworkElement.MouseLeftButtonDownEvent, new
        MouseButtonEventHandler(OnGridMouseDown), true);
}

private void OnGridMouseDown(object sender, MouseButtonEventArgs e)
{
    if (this.playersGrid.IsGrouping)
    {
        var senderElement = e.OriginalSource as FrameworkElement;
        var parentRow = senderElement.ParentOfType<GridViewRow>();
        var parentGroupRow = senderElement.ParentOfType<GridViewGroupRow>();

        // gorup header was clicked
        if (parentRow == null && parentGroupRow != null)
        {
            // provides information line AggregateResults, etc
            //parentGroupRow.GroupViewModel;
        }
    }
}

You can also vote for this feature request which is about adding Group Expanded / GroupCollaped events to RadGridView.
