Popup in Winforms

[Jack Wright]

Dear All,
In Winforms, does anyone know whether we can have an equivalent of
a popup object in Web forms ? In Winforms, we are developing the
Combobox on a concept of a floating window which will align itself
correctly with the base Textbox.
we will control the opening and closing of this floating window.
Does anyone have another or better idea for developing combo boxes in
Winforms?

Also I would like to have a resizable window inside my form (similar
to an MDI form), but the border-style of the form is null...Is it
possible?

Thanks & regards
Jack

Jack,

I did something I believe match your description.

the popup is a form. it opens up as dialog and i capture the leave event to
hide it.

To implement a popup, start with a borderless Form and fill it with a
listbox (for example). Then show that form beside the textbox.

However, for a pure combo like behavior, it gets more complicated. If you
are interested in a commercial solution, check out Essential Tools from
Syncfusion which includes a PopupContainerControl that lets you create
custom popups and provides true popup behavior (combobox like).
