Determine Source of Close

[Steve]

Now that there is a CloseButtonPostion property which can be set to InPaneAndGroup, is there any way to determine the source of the PreviewClose event; either from a pane or from the group?  If not it would be useful.

Thanks in advance,
Steve

I wasn't able to find any straight forward way, but I came up with a bit of a kludge if anyone's interested...

void OnPreviewClose(object sender, Telerik.Windows.Controls.Docking.StateChangeEventArgs e)
{
    RadPane pane = e.Panes.ToList()[0];
    Point pt = Mouse.GetPosition(pane);
    if (pt.X <= pane.ActualWidth)
    {
        // the close came from the pane
    }
    else
    {
        // the close came from the group
    }
}

Still, it would be nice if there were some property that could be tested.
Thanks,
Steve

Hello Steve,

In the RadDocking control there is no definition of "closing a PaneGroup", but only "closing a pane". The RadPaneGroup will be closed (hidden) automatically when it doesn't contain any visible panes. In this scenario I would suggest the following code:

private void dock_PreviewClose(object sender, Telerik.Windows.Controls.Docking.StateChangeEventArgs e)
{
    RadPane pane = e.Panes.ToList()[0];
    if (pane.PaneGroup.Items.Count == 1)
    {
        // this is the last pane in the group and the group will be closed as well.
    }
}

Hope this helps.

Hi George,
Actually I just wanted a way to tell if the user clicked the close button on a pane as opposed to the one on the group.  By doing so I was able to implement a close all on the group button.
Thanks,Steve
