Summary Row "Inline" with grouped rows

[Vicent]

I have made a Custom Summary grouper to show summary data "inline" with grouped rows, it will be great if something similar could be done native.

I attach project example if someone is interested

Hello Vicent,

I appreciate your effort in implementing this and sharing it with the community. 

I am happy to inform you that with the 2024 Q1 version of the controls the RadGridView can show summary row values when groups are collapsed. More information can be found in the Summary rows in a grouped RadGridView section in our documentation. You can check it out and share your feedback.

In addition, we have a KB article that exposes how you can do it before introducing this functionality out of the box: Show Summary Values for Collapsed Groups in RadGridView
