Dynamic Resizing of DropDown User Control

I can get my own user control to show up and function without problem. However, I need to allow the user to resize the dropdown window during the dropped state. I do not want to use the dropdown form since it does not mind the bounds of the user''s screen. How can this be done. Just resizing the user control works if you close the dropdown and reopen it, but I need to resize dynamically. I appreciate any help. Thanks.

In the renderer.DropDownContainerShowingDropDown, set the parent form''s FormBorderStyle to sizable and subscribe to its SizedChanged event. In the renderer.DropDownContainerCloseDropDown, unsubscribe to the event. In the event handler, size both the user control and the container. // in renderer.DropDownContainerShowingDropDown Form f = (Syncfusion.Windows.Forms.PopupHost)this.DropDownContainer.Parent; f.FormBorderStyle = FormBorderStyle.Sizable; f.SizeChanged += new EventHandler(user_SizeChanged); // in renderer.DropDownContainerCloseDropDown Form f = (Syncfusion.Windows.Forms.PopupHost)this.DropDownContainer.Parent; f.SizeChanged -= new EventHandler(user_SizeChanged); //the handler private void user_SizeChanged(object sender, EventArgs e) { this.DropDownContainer.Size = this.DropDownContainer.Parent.Size; ddUser.Size = this.DropDownContainer.Parent.Size; }
