Preserving order of Tabbed Document

[Edward]

Say I have the following in a tabbed document A B C D E.  If I move C out of the group, then dock it back in, it will show up as A B D E C instead.  I guess that's what I need:

1) An event that detects tabbed document movement
2) A method or property that change the order

Hi Edward ,

You can use following code snippet:

private void dockingManager1_DockingStateChanged(object sender, DockingChangedEventArgs e)
{
    if (e.DockObject.DockState == DockState.TabbedDocument)
    {
        if (e.DockObject == documentPane3)
        {
            SetTabPosition(documentPane3, 2);
        }
    }
}

private void radButton1_Click(object sender, EventArgs e)
{
    dockingManager1.RemoveDocument(documentPane3);
}

private void radButton2_Click(object sender, EventArgs e)
{
    dockingManager1.SetDocument(documentPane3);
}

private bool SetTabPosition(IDockable window, int index)
{
    RadTabStripElement tabStrip = ((DocumentPresenterControl)documentPane3.DefaultPresenter).DocumentPresenterElement.TabStripElement;

    for (int i = 0; i < tabStrip.Items.Count; i++)
    {
        if (((DockableTab)tabStrip.Items[i]).Element == window)
        {
            RadItem item = tabStrip.Items[i];
            tabStrip.Items.RemoveAt(i);

            if (index < tabStrip.Items.Count)
            {
                tabStrip.Items.Insert(index, item);
                return true;
            }
        }
    }

    return false;
}

I made a small modification and it works perfectly.

        private bool SetTabPosition(IDockable window, int index)
        {
            RadTabStripElement tabStrip = ((DocumentPresenterControl)window.DefaultPresenter).DocumentPresenterElement.TabStripElement;
            Telerik.WinControls.RadItem item = null;

            for (int i = 0; i < tabStrip.Items.Count; i++)
            {
                if (((DockableTab)tabStrip.Items[i]).Element == window)
                {
                    item = tabStrip.Items[i];
                    tabStrip.Items.RemoveAt(i);

                    if (index <= tabStrip.Items.Count)
                    {
                        tabStrip.Items.Insert(index, item);
                        return true;
                    }
                }
            }
            tabStrip.Items.Insert(tabStrip.Items.Count, item);

            return false;
        }
