Hello Saghar,

Thank you for contacting Telerik Support.

To get the correct order of the Tabs you need to get the instance of the RadPageViewElement. The property Items is a ReadOnlyCollection which holds all the tabs in their correct order. Which means that if you create two Tabs - "Tab 1" and "Tab 2", when "Tab 2" is dragged before "Tab 1" the collection's order will also change. With the sample code below you can get the PageViewElement and use your methods for loading/saving the DocumentTabs:

private RadDock dock = new RadDock();
private RadPageViewElement pageView;

public Form1()
{
    InitializeComponent();
    this.Controls.Add(this.dock);

    for (int i = 0; i < 5; i++)
    {
        this.dock.AddDocument(new DocumentWindow("Doc " + i));
    }
}

public void SaveDocumentsToXml()
{
    // Use pageView.Items
}

public void LoadDocumentsFromXml()
{
}

protected override void OnLoad(EventArgs e)
{
    base.OnLoad(e);
    foreach (Control child in ControlHelper.EnumChildControls(this.dock, true))
    {
        DocumentTabStrip docStrip = child as DocumentTabStrip;
        if (docStrip != null)
        {
            RadPageViewElement pageViewElement = docStrip.TabStripElement;
            this.pageView = pageViewElement;
            break;
        }
    }
}

I hope this information is helpful. Let me know if you require additional assistance.

Hello Saghar,

Thank you for writing back.

In version 2013 Q2 724 the property TabStripElement is of type RadPageViewStripElement which inherits from RadPageViewElement which should not be a problem. However my assumption here is that you are using an earlier version of our controls. If that is the case I would recommend you to upgrade to the latest release.

Let me know If I can be of further assistance.
