I checked that sample code. It is similar to my code.

However, it does not have the solution that I need.

I want to drag out the tab in UltraTabbedMdiManager like below capture.

This solution has one more problem.

If the TabbedMdiManager has multiple tabs, it works, but one tab in the TabbedMdiManager can not be dragged.

Do you know why?

Is there any property that one tab can be dragged out?

No, I made a test with my sample and everything works properly. Could you please give me more details around this issue. If you are able, please modeify my sample to reproduce this issue and revert it back to me. By this way I`ll be able to reserach your scenario.

No, and I`d like to inform you that it is not possible to have such property, because if you want to achieve desired behavior, you should combine two different controls (UltraTabbedMDiManager with their TabDropped event and UltraDockManager with thier Float() method), so no way to have a property for this functionality

Let me know if you have any further questions.

I mean if the tab groups have multiple tabs like below the first picture, tabs can drag out.

However, if the tab groups have only one tab like below the second picture, the tab can not be dragged.

I want to find the way in this situation. Please let me know how to do that.

Thanks for provided information, but mentioned behavior is expected, because by this way your "Listing" (see the screenshot from previous post) at that moment is MDIChildForm and ultraTabbedMdiManager1_TabDropped() event doesn`t fire.

So if you want to achieve desired behavior you should extend your code for example like that:

        private bool IsPressed = false;

        private void ultraTabbedMdiManager1_TabDropped(object sender, Infragistics.Win.UltraWinTabbedMdi.MdiTabDroppedEventArgs e)

        {

            if (e.Tab.UIElement != null)

            {

                ultraDockManager1.ActivePane.Float();

                if (e.Tab.TabGroup.Tabs.Count == 1)

                {

                   ultraTabbedMdiManager1.ActiveTab.MoveToNewGroup();  

                }

            }

        }

       void Control_MouseUp(object sender, MouseEventArgs e)

        {

            if (e.Button == System.Windows.Forms.MouseButtons.Left && IsPressed) IsPressed = false;

        }

        void Control_MouseDown(object sender, MouseEventArgs e)

        {

           if (e.Button == System.Windows.Forms.MouseButtons.Left && !IsPressed) IsPressed = true;

        }

        private void ultraTabbedMdiManager1_MouseLeaveElement(object sender, UIElementEventArgs e)

        {

            e.Element.Control.MouseDown += new MouseEventHandler(Control_MouseDown);

            e.Element.Control.MouseUp += new MouseEventHandler(Control_MouseUp);

            if (e.Element.GetType() == typeof(Infragistics.Win.ImageAndTextUIElement.ImageAndTextDependentTextUIElement) && IsPressed)

            {

                ultraDockManager1.ActivePane.Float();

                IsPressed = false;

            }

        }
