Hi,

Let me know if this works for you or if you have any additional questions.

Thanks for the information.

The CreationFilter approach to add a new  ButtonUIElement looks like a very good solution.

Now I'm trying to make the "FlyIn" Button looks like the other Pane Buttons and align it to the right side with the other Buttons.

I looked on the PaneCaptionButtonUIElement source code, but still not sure how to add this button.

Any idea how to do it?

Thanks,

Mano

Hi,

The PaneCaptionButtonUIElement has ButtonType which is an enumeration including toggle and pushbutton types, so you would have to use the ButtonUIElement to create the button. You can style the ButtonUIElement according to your application look. The position of the button is specified by its rectangle coordinates and size. As the creation filter is called on each recreation of the control you would need to use static variables for the coordinates and the size, something like this:

  class MyCreationFilter : Infragistics.Win.IUIElementCreationFilter

    {      

        public bool BeforeCreateChildElements(Infragistics.Win.UIElement parent)

        {

            // return false so PositionChildElements will get called

            // to do the default child element creation

            return false;

        }

        public void AfterCreateChildElements(Infragistics.Win.UIElement parent)

        {

            PaneUIElement paneUIelement;

            if (parent is PaneUIElement)

            {

                paneUIelement = (PaneUIElement)parent;

                if (paneUIelement.Pane.Manager.FlyoutPane != null)

                {

                    PaneCaptionUIElement caption = (PaneCaptionUIElement)parent.GetDescendant(typeof(PaneCaptionUIElement));

                    List<UIElement> element=new List<UIElement>();

                    if (caption != null)

                    {

                        element = (from el in caption.ChildElements

                                       where el is PaneCaptionButtonUIElement

                                       orderby el.Rect.X ascending

                                       select el).ToList();

                    }

                    if (element.Count != 0)

                    {

                        //the button

                        ButtonUIElement btn = new ButtonUIElement(parent);

                        //coordinates and size depends on your requirements

                        btn.Rect = new Rectangle(new Point(element[0].Rect.X - 17, element[0].Rect.Y), new Size(17, 17));

                        btn.Text = "hide";

                        btn.ElementClick += new UIElementEventHandler(btn_ElementClick);

                        parent.ChildElements.Add(btn);

                    }

                }

            }

        }

        void btn_ElementClick(object sender, UIElementEventArgs e)

        {

            DockableWindow wind = (DockableWindow)sender;

            if (wind.Pane.Manager.FlyoutPane != null)

                wind.Pane.Manager.FlyIn();

        }

    }
