How to show custom control as a drop down window?

Question

I want to show my custom control(eg: monthcalendar) as a drop-down (popup) window. One option is to use ToolStripDropDown and ToolStripControlHost as the second example in msdn example.

My doubt is:

1. ToolStripDropDown should be used for ToolStrip items - is this correct or not?

2. Any other better options to achieve the above requirement?

Answer 1

If you have a simple control, it should be completely fine to use the ToolStripDropDown/ToolStripControlHost combination. More complex controls, however, have sizing, focus, and tab order issues that are difficult to correct. I would recommend that if your custom control has more than one "edit" type child control in it, you're probably better off creating a custom dialog and not trying to make it work in a dropdown.
