Hi Kunal,
Thanks for contacting Syncfusion Support.
At present, we are not having DataTemplateSelector Support for LeftSwipeTemplate and RightSwipeTemplate in SfDataGrid.
We have logged the feature request to “Provide DataTemplateSelector Support for LeftSwipeTemplate and RightSwipeTemplate in SfDataGrid”. This feature will be included in 2018 Volume 4 main release which is scheduled to be rolled out by the mid of December 2018. We appreciate your patience until then.
Regards,
Vigneshkumar R
