[Solved] Hierarchy and SelectionChanged

[Tomasz Wisniewski]

Hi,

I'm using a hierarchy in my datagrid. How can make the SelectionChanged event fire when I click the "+" instead of the row itself?

Hello Tomasz Wisniewski,

You may add a handler for the GridViewToggleButton that listens for the MouseLeftButtonDown event. Afterwards, all you need to do is to find the parent of that button - a GridViewRow in this case and set its IsSelected Property to "True".
For instance:

public MainPage()
{
    InitializeComponent();

  this.clubsGrid.AddHandler(GridViewToggleButton.MouseLeftButtonDownEvent, new MouseButtonEventHandler(OnMouseDown), true);
}

private void OnMouseDown(object sender, MouseButtonEventArgs e)
{
    RadGridView grid = sender as RadGridView;
    var buttons = grid.ChildrenOfType<GridViewToggleButton>();
    foreach (GridViewToggleButton button in buttons)
    {
        if (button.IsPressed)
        {
            GridViewRow parentRow = button.ParentOfType<GridViewRow>();
            if (parentRow != null)
            {
                parentRow.IsSelected = true;
            }
        }
    }
}

Thank you very much. But I have a diferent problem.
Lets say I have to rows in my grid which I expand with the "+" button.

First I expand the row A, then I expand row B.
Now I click on some control which in the expanded area of row A. The problem is, that row B is still selected.
Any suggestions on that?
