RadPane, Fixed Size

[Jay]

Hi,

I'm using Silverlight 4 and Telerik 2011.1.419.1040.  Is there any way to set a fixed width and height for a floating RadPane?  I found the post referring to SL3, however, the assemblies are different and the resource does not compile.

You can force a minimum size or set the size explicitly when the pane switches to a floating pane from a docked pane. You will need to handle the PaneStateChange event on the rad docking control like this:

private void radDocking_PaneStateChange(object sender, Telerik.Windows.RadRoutedEventArgs e)
        {
            foreach (RadPane pane in radDocking.Panes)
            {
                if (pane != null && pane.IsFloating)
                {
                    ToolWindow toolWindow = GetToolWindow(pane);
                    toolWindow.Height = 200;
                    toolWindow.Width = 200;
                }
            }
        }

private ToolWindow GetToolWindow(RadPane pane)
        {
            ToolWindow window = pane.ParentOfType<ToolWindow>();
            if (window == null)
            {
                window = (((pane.Parent as RadPaneGroup).Parent as RadSplitContainer).Parent) as ToolWindow;
            }
            return window;
        }

Hope that helps.

A good idea, however not really the solution I’m looking for.  If I could disable the ability to resize, that would work.  These windows are more like dialogs and cannot dock when they’re in a different state.

Is there any way to prevent the RadPane from resizing at all?

Hello Jay,

You could set the Max/Min Width and Height of the ToolWindow like this:

toolwindow.MinHeight = 200;
toolwindow.MinWidth = 300;
toolwindow.MaxHeight = 200;
toolwindow.MaxWidth = 300;

That will prevent the resize.

Hope this helps.

That worked, partially.  It prevents the window from resizing but the resize icon (arrows) still shows up when hovering over the edges.  Is there any way to prevent the resize icon from displaying?

Code:

ToolWindow parentToolWindow = Telerik.Windows.Controls.UIElementExtensions.ParentOfType<ToolWindow>(radPane);

if (parentToolWindow != null)
{
    parentToolWindow.MinHeight =
        parentToolWindow.MaxHeight = FixedHeight;

    parentToolWindow.MinWidth =
        parentToolWindow.MaxWidth = FixedWidth;
}

Hello Jay,

I thought of a better way to do this. Since Q2 2011 the ToolWindow and the RadWindow inherit a common class. So, you could set the ResizeMode property of the ToolWindow, instead of setting the Min and Max sizes. In that way the ToolWindow won't be resizable and the arrows will be gone.
Another approach is to inherit the DefaultGeneratedItemsFactory and override the CreateToolWindow property.
Please find attached a sample project which illustrates both approaches.

Awesome, now how do I get rid of the little 'X' in the upper corner?  It is disabled since the PaneHeader is not visible, but you can see it.

Hello Cody,

You can try to set CanClose= false, another property that comes from the common class of ToolWindow and RadWindow.

All the best,
