Hi Debashis Pyne,
In order to allow filtering for GridTemplateColumn you need to do the following things:
- Set the AllowFilteringByColumn property of the grid or table view to True. This is needed to enable filtering.
- Ensure that the AllowFiltering property of the template column is True (this is the default value).
- Set the DataField property of the template column to the field you want to use for filtering.
The last point is particularly important since it actually enables the grid to do a specific filtering on a field from the datasource. In your case you might set the DataField property to discussion_date or discussion_time fields from the data source. For more information on this subject please refer to the following help topic and live demo.
Of course you can also create your custom filter using the filter template of the template column and handle the filtering logic yourself.
All the best,
the Telerik team
