Hi,
I have a problem which is hard to isolate and therefor to report as an issue to Infragistics.The problem is that sometimes when an UltraDropdown (dropdown in the grid) or UltraCombois opened (list visible) and the user switches to another application (clicking the taskbar button on thetaskbar) and then back again, only the dropdown list is shown (the dropdown list is shownon top of the other application).
Have anyone else seen this behaviour?
I saw that Infragistics dropdowns are not closed when switching to other applications, which "standardwindows forms" dropdowns do when they are used on an mdi child form.
RegardsTomas.
If it still happens with the latest Hot Fix, then it sounds like it may be a bug. You should try to demonstrate the issue in a small sample project and Submit an incident to Infragistics Developer Support
Now have tried this with the latest version and hotfix (NetAdvantage_20081_CLR2X_HotFix_WIN_2033)and it behaves the same.
I'm not creating controls in run time.

Hi Tomas,
Dropdowns should close when the form that owns them loses focus. So if you switch to another application and the dropdown stays open, it's a bug.
Are you using the latest Hot Fox?
Are you creating controls at run-time? If so, always make sure to add the control to the form's Controls collection. Otherwise, it won't get disposed and it could cause problems like the one you have here.
