How to show correct Filter Dropdown values in a column with a custom CellDisplayTemplate

created 4 years ago

Hi DevEx,

I have a table with a foreign key to display. All readable values from this other table are displayed in a ComboBoxEdit. When using a CellDisplayTemplate the values in the column header filter popup are the ValueMembers instead of the DisplayMembers. When using ComboBoxEditSettings the FilterPopup looks fine. How can I fix this?
I attached a small sample showing this behavior.

Best regards,
Daniel

Hello Daniel,

CellDisplayTemplate does not affect data filtering, similar to CellTemplate. Please check the following topic where we compared CellTemplate with other ways to customize display text - Format Cell Values.

If the EditSettings property meets your requirements, I recommend you continue using it. This technique is the best in terms of performance and compatibility with other features. Otherwise, combine CellDisplayTemplate/CellEditTemplate with other techniques that affect filtering. For example, use CellEditTemplate along with EditSettings.

Thanks

      Hi Ivan,

      I wasn't aware that EditSettings and CellEditTemplate can be used together.
      That work just fine for my case.
      Thanks for your help.

      Best regards,
      Daniel
