Can I prevent the detailTemplate's render when I sort the Grid?

[Chris]

I put some kind of subGrid in the detailTemplate of kendoGrid, then I do some changes to the subGrid, but after I sort or filter the kendoGrid, I just found what i did was gone. So what should I do? maybe there's some method can do the job that when i change the datasource of kendoGrid, which can prevent the detailTemplate's render?

Hello Chris,

The observed behavior is by design and I am afraid it cannot be prevented out-of-the-box. When the Grid's datasource fires its change event, the Grid rebinds in order to show valid and up-to-date data.

I am not aware of your exact scenario, but you can try thinking in the opposite direction - what should be done, so that the subGrid state is persisted after the outer Grid is rebound.

Kind regards,
