I have been trying to solve a problem where a popupcontainer disappears when I select a syncfusion comboboxadv but not when I select a windows.forms.combobox.

I read this FAQ and created a custom popupcontainer that overrides the IsRelatedControl.

This fixed the popupcontainer if it is programmatically opened.  This does not stop the popupcontainer from disappearing if opened using a popupmenu.  Also the FAQ breaks the default behavior and closes regardless of what control is selected.

Hi Chris Bishop,
By setting the PopupControlContainer as the popup parent for comboxbox'x popupcontainer, you can avoid closing of the combobox's dropdown.
void comboBoxAdv1_DropDown(object sender, EventArgs e)
            comboBoxAdv1.PopupContainer.PopupParent =dropDownBarItem1.PopupControlContainer;
            dropDownBarItem1.PopupControlContainer.CurrentPopupChild = comboBoxAdv1.PopupContainer;             
Please let us know if you need any other details.
We are glad to help you on this.
Thillai. C
