The current application has bugs in Combobox. When user selects an option and deletes the selected option and attempts to save, the value does not revert to null. Instead the last selection is still kept. It is a databound combo box. Need help with adding a blank option which will set the value to NULL if blank option is selected.
If you can work with me through [url removed, login to view] that would be great.
It should not be much effort.

It looks not very complicated. Can you provide your app? Maybe it's better to resolve with TeamViewer, especially if your app requires prepared environment (database, system settings) for working.
