Grid aggregate rows not displaying when using virtual scroll

[Jim]

Hi, 

I'm trying to get group footer rows to display while using virtual scrolling. They display just fine without virtual scrolling, but once I enable it, they are nowhere to be found.

I've been trying different combinations for the past few hours, trying to figure this out with no luck.Here is a simplified example: https://stackblitz.com/edit/angular-9f2v8c

The example has virtual scrolling enabled. As a result, the footer aggregate rows are not displayed. If you remove line 9, you'll see the footers appear. How can I get the footer rows to display with virtual scrolling enabled?

Thanks

Jim

Hi Jim,

Thank you for the provided example.

When using the groupFooterTemplate then the [groupable] option should be set to:

[groupable]="{showFooter: true}"

Please check the following example:

Indeed, that is something that is currently missing from our documentation. Thus I have updated your account Telerik points for bringing that to our attention.

We will try to provide an internal fix that will set the [groupable] option properly and automatically under the hood when using the kendoGridGroupBinding directive. But if we face some corner stones with this approach, we will update the documentation accordingly to show that setting as required.

Thank you for the provided feedback. Please let me know in case any further assistance is required for this case.
