RadDock - Dynamically adding UserControls with autoscroll

[Pawz]

How do I get this to work? I'm dynamically adding a UserControl to the Dock control, and I can't seem to get the docked window to get scrollbars to show up when it is resized.

CSUserControl itemControl;

            if (typeof(CSUserControl).IsAssignableFrom(ucType))
            {
                itemControl = (CSUserControl) Activator.CreateInstance(ucType, parameterList);
            }
            else
            {
                UserControl item = (UserControl)Activator.CreateInstance(ucType, parameterList);

                itemControl = new CSUserControl();
                itemControl.Controls.Add(item);
                item.Dock = DockStyle.Fill;
            }

            Size size = itemControl.Size;
            //Hook up events
            itemControl.WindowChangeRequested += documentPane_WindowChangeRequested;
            itemControl.WindowOpenRequested += documentPane_WindowOpenRequested;
            itemControl.WindowCloseRequested += documentPane_WindowCloseRequested;

            itemControl.AutoScroll = true;

            HostWindow host;
            if (dockPosition == DockPosition.Fill)
            {
                host = _dock.DockControl(itemControl, dockPosition, DockType.Document);
            }
            else
            {
                host = _dock.DockControl(itemControl, dockPosition);
            }


            host.Text = documentName;
            host.Name = documentName;
            host.CloseAction = DockWindowCloseAction.CloseAndDispose;
            host.AutoScroll = true;
            host.TabStrip.AutoScroll = true;
            //host.TabStrip.MinimumSize = itemControl.MinimumSize;
            //host.MinimumSize = itemControl.MinimumSize;

            DockTabStrip strip = (DockTabStrip)host.TabStrip;
            strip.SizeInfo.AbsoluteSize = size;
            _dock.ActivateWindow(host);

CSUserControl is simply a wrapper around the standard UserControl that gives me some extra functionality.

I've gotten it SORT OF working by using the commented out lines above - when I set the TabStrip AutoScroll  = true and the minimum size as well, then the scrollbars show up. BUT it's terrible in implementation - the tabstrip randomly disappears or repeats itself, scrollbars show up when they're not supposed to be, scrolling around wrecks the tabstrib.

How am I supposed to be doing this?

Hi,

Besides setting the Form Autoscroll property to true, you also need to set the AutoScrollMinSize to the size that you want the scroll bars to appear.
