Scroll bar not showing on ultradropdown
posted

I have a ultramaskededit control with an editbutton set to a ultradrop the displaylayout.scrollsbars property is set to automatic but the scroll bar never shows.  Another question is there a sample app that shows how to use the ulltradropdown with a textbox or maskededitbox?

 

thanks

    If I understand you correctly, you are assigning an UltraDropDown control to the DropDownEditorButton's Control property. If that's the case, then this will not work. An UltraDropDown cannot be used this way - it's not a standalone control - it only works as a ValueList in an UltraWinGrid or other control. 

    If you want a dropdown grid on your UltraMaskedEdit control, then you should use the UltraWinGrid control.
