Hi sdcox451,

When a datagrid has a TemplateDataField, that column is not actually bound to any data.  You might be adding eval statements to show data in the cells, but the cells don't have a value the same as a BoundDataField.  So, there would be no way for the grid to filter on that column. 

What you could try to do is add another hidden column that shows the data that you want to filter by and add filter conditions on that column.  You would also probably need to have a custom filtering UI on your tempalte column.
