        </ComboBox>

cboRecordType.Text is empty, didn’t cantain the selected Text, how to get that

Answer 1

In the SelectionChanged event handler, you can either look at the cboRecordType.SelectedItem property on the combobox itself, or you can look at the AddedItems property of the SelectionChangedEventArgs passed into the event handler.

When an item is selected, the item is added to the AddedItems array property of the event args. (multiple items in a multi select case). When an item is deselected, it is added to the RemovedItems array property of the event args.
