RadDock: Crash after downloading latest version

Hello,

I have downloaded the latest winform version today and launched my application.

I experienced an immediate crash while replacing a document container by a split container.

You can see the small piece of code and the insttruction which is causing the crash ....

Obviously it was working properly before upgrading ...

Can you help? I am now just stuck so a fix or a workaround would be useful...

Thanks,

Olivier D.

if (ctrlOutput == null)
{
Telerik.WinControls.UI.RadSplitContainer mainSplitContainer = null;

ctrlOutput = new ToolWindowOutput(sbOutput);

var Output = new Telerik.WinControls.UI.Docking.ToolWindow();
Output.Text = "Output";
Output.Controls.Add(ctrlOutput);

var toolTabStrip = new Telerik.WinControls.UI.Docking.ToolTabStrip();
toolTabStrip.Controls.Add(Output);

if (this.documentContainer1.Parent == this.radDock1)
{

>>>>>>>>>>>>>>>>>>>>>>>>>>>>

this.radDock1.Controls.Remove(this.documentContainer1); <<<< CRASH HERE

>>>>>>>>>>>>>>>>>>>>>>>>>>>>
// need to remplace document container by a split container
mainSplitContainer = new Telerik.WinControls.UI.RadSplitContainer();
mainSplitContainer.Orientation = System.Windows.Forms.Orientation.Horizontal;
mainSplitContainer.Controls.Add(this.documentContainer1);

this.radDock1.Controls.Add(mainSplitContainer);
}
else
{
mainSplitContainer = (Telerik.WinControls.UI.RadSplitContainer)this.documentContainer1.Parent;
}

mainSplitContainer.Controls.Add(toolTabStrip);

Hello, Olivier,

Following the provided information I have prepared a sample project containing a RadDock and using your code snippet. I was able to observe the error message. Indeed, in the previous version it didn't crash.

I have logged it in our feedback portal by making this thread public. You can track its progress, subscribe for status changes and add your comments on the following link - feedback item.

I have also updated your Telerik points.

Currently, the possible solution that I can suggest is to use the following custom implementation for the existing DocumentTabStrips in RadDock:

        public class CustomDockTabStrip : DocumentTabStrip
        {
            public override string ThemeClassName
            {
                get
                {
                    return typeof(DocumentTabStrip).FullName;
                }
            }

            protected override void OnDockManagerChanged()
            {
                if (this.DockManager != null)
                {
                    base.OnDockManagerChanged();
                }
            }
        }

        private void InitializeComponent()
        {
            this.radDock1 = new Telerik.WinControls.UI.Docking.RadDock();
            this.documentContainer1 = new Telerik.WinControls.UI.Docking.DocumentContainer();
            this.documentWindow1 = new Telerik.WinControls.UI.Docking.DocumentWindow();
            this.documentTabStrip1 = new CustomDockTabStrip();
        //some other code
        }

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
