I am binding my xml data to the datagrid via the light weight datatable that you guys gave me. I have adjust each DataColumn class to have bool to indicate if the column should be visible in the grid. Most of the columns I hide are actually companion columns that have the unit associated with a value. For instance, there would be a Temperature column and the next column would be Temperature unit Column. I would like merge the values of these columns but still be able to filter the value based on datatype. Is there an easy way to do this?
In the example above I want the Temperature column to show its value + value of its companion unit column but still be allowed to filter (such as Temperature > 30.)

Hello Matt ,
I have tried to illustrate a scenario close to yours ( please see the attached project) . There we have two fields - one with the value of a temperature and one with the unit.
Using a custom value converter we merge both values to have them displayed in a single column .
To preserve filtering we keep the DataMemberBinding pointing to the TempValue field.
To have the ValueConverter in action we replace the default cell template with a textblock bound to the underlying object via our converter.
To see all this in action just run the project attached. It uses a List of .Net objects but with a small change in the Convert() method it can be easily adapted to use the "datatable".
