Show int column as translated string + filter on string

Hi,

I want to show a DataGridColumn showing strings based on an id.

Typicaly:

Class Device
{
Public string name {get; set;}
Public device_type_id {get ; set ;}
}

Class DeviceType
{
Public int device_type_id { get ; set; }
Public string name { get; set;
}

Extension with Device with “device name” is not possible, device comes from a WCF service.I can write a new class but that results in lots of overhead.

I want a filter column allowing to filter on device type, looking like:

However when selecting an item to filter, I receive an exception, see below
I defined the column as joined:

Someone any suggestions what goes wrong?

Your DropDown Multiple should be set to true not false according to the DataGrid column Type.

does the trick - thx
