[OPEN] ComboBox Value
Hello,
The example below will demonstrate that I can not submit a value in a ComboBox that is not in the list:
1. Enter "Timothy" into Combobox
2. Click "Save"
3. Notice it doesn't show Timothy as selected
4. Select "Consultant" from Combobox (or type it)
5. Click "Save"
6. Notice it knows my selection
I thought it might be the SelectedItem property, because I haven't really selected anything, but even the underlying Value property is null. Have I missed a property setting to make this work?
Cheers,
Timothy
