Hi Bhuvaneshwari,
Your GridTemplateColumn settings are correct and if you set the AllowFilteringByColumn property of the grid to true you will be able to filter by the "CreaQualification" data field for that column. Please keep in mind that the filtering is performed on the data field and not on the displayed values in the cells.

You can test the above by entering "2" in the filter and choosing the "Contains" filter function.
Hope this helps.
