Hi Kumar,
Thanks for contacting Syncfusion support.
ColumnTemplate:
You achieve the ColumnTemplate by using GridTemplateColumn. It is derived from GridColumn, and hence it inherits all the properties of GridColumn. It allows you to extend the functionality of GridColumn with your own view by creating the CellTemplate of GridTemplateColumn. Please refer the below UG link to get more details about GridTemplateColumn
RowTemplate:
Currently we do not have support for RowTemplate in SfDataGrid. Already we have added this feature to our feature management system and this feature will be available any of our upcoming volume release (tentatively).
You can customize the GridStyle by writing a Style class overriding from DataGridStyle and assigning it to the
SfDataGrid.GridStyle property. Please refer the below UG link to get more details about GridStyle:
Regards,
Ashok
