I found a bug :

VS 2019.16.10.0 / Telerik 2021.1.218.1

strangely, I had functionalities that disappeared in my grid "group" and i found how to reproduce the problem :

In radgrid, from designer :

1) open property builder and add columns.

2) get a column and add it to group panel.

3) uncheck group panel check (example because must in group but user must don't touch it and can't add)

4) in columns, column added to group, uncheck "isVisible".

5) bind datas for example.

run project : Ok works.

now Open again property builder, rename not group column header, click Ok.

save, run project : group disappeared, if you go in designer group descriptors : all is empty.

Hello, Vincent,

Following the described steps and changing the HeaderText for a non-grouped column seems to work as expected on my end and GroupDescriptors are preserved after the changes in Property Builder. One of the tests I performed is captured in the attached gif file.

I would recommend you to give the latest version 2021.2.511 a try and see how it would work on your end since we have made some improvements in the Property Builder. Please let me know what is the observed result on your end.

If you need any further assistance please don't hesitate to contact me.
