Hi All,

I ran across the same issue as described in the following link, http://community.infragistics.com/forums/t/1113.aspx

I tried the solution proposed and it worked to a large extent. When I click on the X button I get a panehidden message, where I close my control and dispose the dockcontrolpane. When I save and load the layout, I get a empty panel in  the top left corner. After playing around with it quite a bit I couldn't get around removing the blank panel. 

Is there a solution for this? Can you point me in the right direction ? 

See my creation code and remove code below,

.// My usercontrol

LiveVariableDataControl wpf = new LiveVariableDataControl();

wpf.Size = new Size(200, 200);

UltraTile tile = new UltraTile();

tile.Control = wpf;

UltraTilePanel tilep = new UltraTilePanel();

tilep.TileSettings.ShowCloseButton = Infragistics.Win.DefaultableBoolean.True;

tilep.Appearance.BackColor = Color.Transparent;

tilep.add(tile);

DockableControlPane dockableControlPane1 = new DockableControlPane(tilep);

dockableControlPane1.Size = new Size(210, 210);

dockableControlPane1.Settings.Appearance.BackColor = Color.Transparent;

DockableControlPane dockableControlPane1 = new DockableControlPane(tilep);

dockableControlPane1.Size = new Size(210, 210);

dockableControlPane1.Settings.Appearance.BackColor = Color.Transparent;

DockAreaPane flpane =   MainFormDockManager.DockAreas.Add(DockedLocation.DockedLeft);

flpane.Panes.Add(dockableControlPane1);

flpane.Closed = false;

flpane.Tag = id;

flpane.Size = new System.Drawing.Size(264, 583);

flpane.Settings.Appearance.BackColor = Color.Transparent; 

//Pane Hidden method

private void MainFormDockManager_PaneHidden(object sender, PaneHiddenEventArgs e)

{

 removeControlPaneAndChildren(e.Pane);

 e.Pane.Closed = true;

}

private void removeControlPaneAndChildren(DockableControlPane pane)

{

            UltraTilePanel tilep = pane.Control as UltraTilePanel;

            if (tilep != null)

            {

                while (tilep.Tiles.Count > 0)

                {

                    UltraTile tile = tilep.Tiles[0];

                    IUIControl ctrl = (IUIControl)tile.Control;

                    ctrl.close();

                    tile.Control.Dispose();

                    tilep.Tiles.Remove(tile);

                    tile.Dispose();

                }

            }

            pane.Dispose();

}

Any help is greatly appreciated

Thanks!
