I need a simple solution to have a Button next to an edit field to show up some simple options for the user to choose from.
I thought and tried this:- put an UltraDropDownButton on the Form- put an UltraPopupControlContainer on the Form- put an ContextMenuStrip on the Form
I choosed a simple MenuStrip because it's simple to use (i only need a few entries that i put in at runtime)
In the PopupContainer i've set "PopupControl" to the MenuStrip (design time)
In the DropDownButton i've set "PopupItem" to the "MenuStrip [PopupControlContainer]" (design time)
Now, if i run the application and press the DropDownButton i get an error: (translated something like 'the control of the topmost level cannot added to a control')

In this case i have:- a windows form- on that form a UserControl i've written- That UserControl is creating other UserControls at runtime and placing it on itself- These runtime-created UserControls are the ones that have the DropDownButton on it (besides other controls) plus the MenuStrip and the PopupControlContainer of course.
If you have any idea how to solve this please let me know. If you have another simple idea how to get a small dropdown-button showing a simple menu i would be happy too. I decided to choose Infragistic DropDownButton in case that some day i need to popUp a more complex UserControl or something else instead of that simple menu - so it would be easier to extend in future... But if this is too complex i would rather choose a simpler way :)
Hi,
PopupControlContainer needs to contain a fixed Control. The ContextMenu really isn't a control - it's another popup. So that's not going to do what you want.
The PopupItem on the UltraDropDownButton takes an IPopupItem. There are two things that implement this interface. The first is the PopupControlContainer - but as we've already established, that won't work for you.
The second is a PopupMenu from an UltraToolbarsManager. So what you could so here is use an UltraToolbarsManager and go into the designer and create a PopupMenu with some items on it, rather than using the inbox ContextMenu(Strip).
Another option would be to use UltraTextEditor ar eyou "edit field", or maybe one of the other editor controls. You could use the ButtonsRight collection to add a button to the control. Then you could trap for a MouseUp event on the control, use the UIElements to determine the location of the MouseUp and determine if it was on the button. And then you could manually show your ContextMenu.
