My application is using most of the Dev Express controls.Using QTP we are unale to identify the Objects.so we are planning to implement the .Net Dll using .net extensibility.

Does the below process works?
Letís assume that,
a. I have created a new DLL for Dev express Combo box.
b. I have mapped this control to SwfComboBox.
c. I want only the default methods which are available for SwfComboBox. So without updating the DLL (TestRecord,TestRun) I have configured the dll with QTP.
Now can I access the Parent Object(SwfComboBox) methods from QTP?

Please reply soon..
