I have been able to get the supplied data format changed just a little to allow for me to make the necessary alterations to get the data in a format more suitable for usage with the ComboBox.  The grid now works successfully. Thank you for your assistance.  

Marc,  Now that I have had the weekend to review everything again, I believe there may be room for manipulation of the data columns into a more standard lookup style format utilizing the Id column within the data. Let me try a few things and will post back the results later today or tomorrow. 

Marc, The data sample I sent to you was exactly what is going to be received for consumption by the grid. Changing the sample data does not resolve the issue. To give you a bit more of an idea of what needs to be done, I have attached an Excel worksheet with a sample of the actual  ExchangeRates structure with the data anonymized. The key ...

Marc, Attached is sample project replicating the error that I get using the CellViewManager, not being able to see the RateDescriptor value in the column instead of the Id value of CURRDOL and the ComboxBox selection not being saved when changed. Thanks.

Additionally, the initial displayed value in the column with the combobox is the value member and not the display member.    

Thanks for the reply but the problem is with the Combobox and not the checkbox. The checkbox works just fine.   As for setting the CellViewerManager for the Combobox, I try to do that and I get an error indicating that the Key value - blah blah has already been loaded into some dictionary.  

I know I have to be doing something wrong but just can't find the issue. I am using v3.9 of the .Net Grid. Problem: When the grid is displayed in the form, the combobox column is displaying the value of the column from the binding dataset for the grid. When I click on the cell, the combox displays the appropriate caption information. But when I ...
