(2013.1.220.40) DraggedSokutContainer is obsolete Warning

[Robert]

**** SORRY - the title should have read 'DraggedSplitContainer is obsolete' - TYPO ****

Hi,

I'm getting the following warning in VS2010 when using wpf libraries 2013.1.220.40.

'Telerik.Windows.Controls.Docking.PreviewShowCompassEventArgs.DraggedSplitContainer' is obsolete: 'This should not be used anymore. Use the DraggedElement property instead.

It's relating to the following code I have for conditional pane docking:

private void RadDocking_PreviewShowCompass(object sender, Telerik.Windows.Controls.Docking.PreviewShowCompassEventArgs e)
{
    if (e.TargetGroup != null)
    {
        e.Compass.IsCenterIndicatorVisible = CanDockIn(e.DraggedSplitContainer, e.TargetGroup, DockPosition.Center);
        e.Compass.IsLeftIndicatorVisible = CanDockIn(e.DraggedSplitContainer, e.TargetGroup, DockPosition.Left);
        e.Compass.IsTopIndicatorVisible = CanDockIn(e.DraggedSplitContainer, e.TargetGroup, DockPosition.Top);
        e.Compass.IsRightIndicatorVisible = CanDockIn(e.DraggedSplitContainer, e.TargetGroup, DockPosition.Right);
        e.Compass.IsBottomIndicatorVisible = CanDockIn(e.DraggedSplitContainer, e.TargetGroup, DockPosition.Bottom);
    }
    else
    {
        e.Compass.IsLeftIndicatorVisible = CanDock(e.DraggedSplitContainer, DockPosition.Left);
        e.Compass.IsTopIndicatorVisible = CanDock(e.DraggedSplitContainer, DockPosition.Top);
        e.Compass.IsRightIndicatorVisible = CanDock(e.DraggedSplitContainer, DockPosition.Right);
        e.Compass.IsBottomIndicatorVisible = CanDock(e.DraggedSplitContainer, DockPosition.Bottom);
    }
    e.Canceled = !(CompassNeedsToShow(e.Compass));
}

CanDockIn Method:

private bool CanDockIn(ISplitItem dragged, ISplitItem target, DockPosition position)
{
    // If there is a pane that cannot be dropped in any of the targeted panes.
    return !dragged.EnumeratePanes().Any((RadPane p) => target.EnumeratePanes().Any((RadPane p1) => !CanDockIn(p, p1, position)));
}

Can you offer any suggestions about how I can fix this?

Thank you for your time,

Rob

I fixed it this way:

e.Compass.IsTopIndicatorVisible = CanDockIn(e.DraggedElement, e.TargetGroup, DockPosition.Top);           }

private bool CanDockIn(object dragged, ISplitItem target, DockPosition position)

{

// If there is a pane that cannot be dropped in any of the targeted panes.

if (dragged is ISplitItem)

{

return !((ISplitItem)dragged).EnumeratePanes().Any((RadPane p) => target.EnumeratePanes().Any((RadPane p1) => !CanDockIn(p, p1, position)));

}

 

return false;
}

This worked for me.

Hello,

We would suggest using e.DraggedElement property instead of e.DraggedSplitContainer. Hope this helps.

Kind regards,
