Hi Team,
We have a requirement that in hierarchical GridView user should able to sort only current Expand Template(ChildGrid) records when there are multiple expanded template. so we are having issue to implement  the functionality for 'Application should sort the selected or expanded child grid results only'.
I am attaching screenshots  for reference.
Thanks
Dinesh

Hello Dinesh,

We kindly ask you to use just one support channel to contact us. Posting the same questions numerous times slows down our response time because we will need to review and address two or more tickets instead of one. Moreover threads are handled according to license and time of posting, so if it is an urgent problem, we suggest you use a support ticket, which would be handled before a forum thread.

I am copying my answer here as well, so the community can benefit from it:
By design RadGridView uses ChildGridViewTemplates to display different hierarchy levels. All currently expanded child rows (at the same level) corresponds to one and the same GridViewTemplate. It is allowed to modify the template, but as it is common to all ChildViewInfos, its changes reflects to all the child rows at this level - to the whole template. It is normal and desired behaviour for hierarchical RadGridView, because this child template is some kind of a pattern for constructing the child rows view. So, to answer your question, it is not supported to have different child templates for each child row at the same level with the purpose to modify them individually. 

Thank you for your understanding.
