Self-Referential Foreign Key field in Grid

[Nicholas]

I have a grid for a model Departments. Departments has a foreign key field ParentDepartmentKey. The foreign key field correctly generates a dropdown list with Departmens listed. However, if you add a new department, it is added to the grid, but the dropdown in the foreign key field is not updated and does not update.

Is it possible to have the foreign key field update when an item is added to the grid?

Hi Nicholas,

 
From the provided information it seems that you either bind the ForeignKeyColumn to a nullable field from the model or you never defined default value for current field. Please check the possible solutions for both cases:

• Bind the ForeignKeyColumn to a nullable field - we already provide example how to achieve this in our CodeLibrary
• Define default value for this field

Kind Regards,
