Hi,

I used the following code to add a docked control in my form:

        public void DockControl(string area, string group, string key, string text, Control control)
        {
            if (control == null)
                return;

            if (ultraDockManager1.DockAreas.Exists(area))
            {
                DockAreaPane areaPane = ultraDockManager1.DockAreas[area];
                DockableGroupPane groupPane = null;
                if (areaPane.Panes.Exists(group))
                {
                    groupPane = areaPane.Panes[group] as DockableGroupPane;
                }
                if (groupPane == null)
                {
                    groupPane = new DockableGroupPane(group);
                    groupPane.ChildPaneStyle = ChildPaneStyle.TabGroup;
                    areaPane.Panes.Add(groupPane);
                }
                DockableControlPane pane = new DockableControlPane(key, text, control);
                groupPane.Panes.Add(pane);
                groupPane.Text = pane.Text;
         }
    }
   
   
            string leftKey = "LeftDockArea";
            DockAreaPane areaPane = this.ultraDockManager1.DockAreas.Add(DockedLocation.DockedLeft, leftKey);
            areaPane.Size = new Size(250, 150);

            string groupKey = "LeftDockGroup";
            this.DockControl(leftKey, groupKey, "Property", "Property", control);

I also added some UltraTree as the docked controls in the same way, and use ultraDockManager1.SaveAsXML/LoadAsXML to save/load the layout.

My problem is that when I load the layout back, it is a mess. I cannot even work with the tree and the application becomes no responding. I'm not sure if I use the ultraDockManager in the right way, can anyone tell me what is my problem? Thanks a lot!
