title: No event triggering on change in the UI
body: <p>I am working on a project, and we are using Infragistics as a third party control library. We have not provided with any documentation of the project and only thing I know is they have used MVP design pattern. Now I am trying to debug the application based on the task given to me.</p>
  
  <p>I have a custom grid (mostly from Infragistics) and it has three columns "ColA, ColB, ColC". ColB and ColC have comboboxes. ColB and ColC already are bind to a datasource. When I change the selected item in the ColB combobox, based on the selection in ColB, ColC combo collection refines itself(removes few items based on the value in ColB). Here I need to change some logic in the collection refinement for ColC based on the ColB selected value. But I am not able to as I am not sure where the refinement is taking place. I tried placing the breakpoints, but there is no event triggering while changing the value in ColB and thus I dont know the codes related to refinement.</p>
  
  <p>I know the question is specific to my project, but what my question is that is there any way to get to the codes based on the action taken by me in the UI apart from breakpoints? Or is there any approach I should be following in this situation? I am not very good in debugging tools.</p>
  
  <p>Thank You.</p>
