Hello,

When using the .FooterTemplate() configuration, both in ASP.NET Core environment as well as when using jQuery, as shown here https://dojo.telerik.com/@AleksandarEvangelatov/ukIwEpaZ the template receives the event data as a parameter, but not the widget instance. When using data-template MVVM binding there is a known limitation where the data-template attributes cannot contain inline template definitions, but only ID's of external templates. When using an external template, the template receives the widget instance as a parameter https://dojo.telerik.com/@AleksandarEvangelatov/ukOjaxEc .To receive the widget instance as parameter in ASP.NET Core use the .FooterTemplateId() configuration and pass the ID of an external template.

Regards,
Aleksandar
