I still have a refresh problem on my hierarchical grid.......
I am sorry for asking again, but, it makes me depressed :)
Check on our ExpandGrid in the Essential Suite Sample \ DataBound \ hierarchical \ ExpandGrid
* Expand a row
--> for exemple : expand 3 - Confections
* Modify categoryID of the row
--> for exemple : replace 3 by 33
the childs automaticly change their key value
* then, clic on child rows : They disappear!!!
* then, To have the right display, you need to collapse the row and expand it again!
So, how to refresh it correctly?
