Hi Kenney,
Greetings from Syncfusion support.
We would like to inform you that, the Column Template feature of grid is only for display purposes. You can customize the display content for a cell in grid using this ColumnTemplate feature. But all the DataOperations and CRUD operations for the corresponding customized column will be handled only based on the Field property value of the corresponding column. This is the default behavior of performing search action in Grid.
Please get back to us if you need further assistance.
Regards,
Renjith R
