I've a parent/child grid and I need to edit some columns in the child grids.
When the page load the server send all the parent and children data needed to work in the client side, I mean, the user will be able to expand any child grid without the need of reading the data from the server when expanding a grid because the data is already in the client.
I've attached a screenshot.
Currently I've populated the child grids and I'm able to edit the rows but every time I edit one row in any child grid and the editor lose the focus the parent grid collapse all expanded children keeping the edited values.
I've been working around that but I've no idea how to fix it and I've never used the Telerik controls.
Here I attached a clean project reproducing the issue https://www.dropbox.com/s/9g76yrbccwh11r3/TelerikMvcApp1.7z?dl=0
I really need to be able to edit the child grids without READING data from the server every time the user expand a child because the data in the child grid is built using heavy calculations and it takes a lot of time to finish.
Can anyone help me fix the problem?
