Hello,

I have a scenario where I need to have cell text to display one databound field from an entity property, but when in edit mode I would like to use a dropdownlist to change the underlying entity itself and not the value being displayed.

For example my entity in simple terms is as follows:

Vehicle (Main databound entity)
-- Vehicle.Make (relates to Make entity)
-- Vehicle.Model (relates to Make entity)
-- Vehicle.Year (relates to Year entity)
-- Vehicle.Region (relates to Region entity)

Make
-- Make.MakeID
-- Make.MakeName

Model
-- Model.ModelID
-- Model.ModelName

Year
-- Year.YearID

Region
-- RegionID
-- RegionAbbr
-- RegionFullName

I would like to have for example a Region column that displays Region.RegionAbbr in the cell text, but when entering edit mode give a list bound to Region enities.  These entries should be bound to a List<Region> and displaymember should be set to RegionAbbr for display purposes.  When an entity is selected from the dropdown, instead of altering Region.RegionAbbr I would like to intercept the change and assign the Dropdownlist DataBoundItem to the Vehicle.Region entity.

Can this be done?

Hello Bobby,

Thank you for writing.

I am not completely sure about your requirement, but it looks like a classical data-bound scenario. If this is the case, you can use the standard GridViewComboBoxColumn or GridViewMultiComboBoxColumn to implement drop-down editor with value and display members. For more details, please refer to our product documentation.

If this does not help, please open a new support ticket and send me a small sample project, which demonstrates your scenario along with detailed description of your goal. This will allow me to investigate further and provide you with accurate assistance.

Best wishes,
