Could you upload a small sample shell which shows the layout?  Or possibly a picture describing it?  Do you use aligned controls in the MDI form?

Hi,

I have the same issue in C#.Net within a Child Form. I noticed that all appears to be fine with the DockingPane object when the form is opened, however when I open another form and go back to the first form with the docking panes the Action event no longer seems to work! It seems as though the Action event has disconnected itself.

Therefore when I hide and show the panes they don't repaint correctly and the only way I can get this to repaint is by calling the RecalcLayout() method in a timer object after this has been created but this is not the best way to resolve this. Can anyone from Codejock please check this out?

I have sent in a support ticket too as I need this resolved rather urgently.

EDIT: I have since discovered that this appears to be fine on several forms that use Docking Panes, the form I am having an issue with contains the TrackControl object. The code is no different from every other form yet the one with the TrackControl causes the issue.

Just a quick update on this, forgot to do so quite some time ago...

I have resolved this issue. It appears that you cannot use the DockingPaneManager control within C#.Net the same way as you would in VB due to how the .Net forms initialise.

So to resolve this I had to put the initialise code for the docking pane into a reusable method for building a DockingPaneManager (not easy if you're not too sure what you're doing) and this could then be added to the load event. Works everytime now without any issues whatsoever.

See the code below:

/// <summary>
/// Creates a DockingPaneManager object
/// </summary>
/// <param name="frm"></param>
/// <returns></returns>
public static AxXtremeDockingPane.AxDockingPane DockingPaneManager(Form frm)
{
    AxXtremeDockingPane.AxDockingPane DockingPaneManager = new AxXtremeDockingPane.AxDockingPane();
    ((System.ComponentModel.ISupportInitialize)(DockingPaneManager)).BeginInit();
    frm.SuspendLayout();

    DockingPaneManager.Enabled = true;
    DockingPaneManager.Location = new System.Drawing.Point(21, 12);
    DockingPaneManager.Name = "DockingPaneManager";
    DockingPaneManager.Size = new System.Drawing.Size(24, 24);
    DockingPaneManager.TabIndex = 0;

    frm.Controls.Add(DockingPaneManager);
    ((System.ComponentModel.ISupportInitialize)(DockingPaneManager)).EndInit();
    frm.ResumeLayout(false);

    DockingPaneManager.AttachToWindow(frm.Handle.ToInt32());
    DockingPaneManager.VisualTheme = XtremeDockingPane.VisualTheme.ThemeResource;
    DockingPaneManager.Options.HideClient = true;
    DockingPaneManager.PaintManager.HighlightActiveCaption = false;
    DockingPaneManager.PaintManager.SplitterStyle = XtremeDockingPane.DockingPaneSplitterStyle.PaneSplitterSoft3D;
    DockingPaneManager.PanelPaintManager.Layout = XtremeDockingPane.XTPTabLayoutStyle.xtpTabLayoutAutoSize;
    DockingPaneManager.SendToBack();

    return DockingPaneManager;
}

How to use this:
// Create a global DockingPaneManager variable
private AxXtremeDockingPane.AxDockingPane DockingPaneManager;

//In the load event, create the object and use as you would have in VB6.
DockingPaneManager = BSDLibrary.Codejock.DockingPaneManager(Instance);


You need to pass the Form instance of which you are adding the DockingPane to and that's all.
