Hello,
I've faced an issue with remote data and tree rendering.
So the first problem I faced is that when you execute refresh after expanding row it refreshes the grid with additional params that were added while getting child data.
Sequence:
1) Loaded treeGrid
2) Expanding one of the grid trees
3) Executing treeGrid.refresh() function. It executed with additional params that were passed for child data to render and now whole grid is just that row child data
What I could do and I did: removed params that stayed in query and then grid will be loaded as in the first picture where parent_ID is NULL.
Query: But what if I want grid to be expanded as it was before the refresh ?
So there are two ways that would work:
1) Refresh grid with parent_ID null and then expand elements to where the user was (This might be slow, cause we'll need all the child data to load again) and I couldn't manage to do it with treeGrid expand methods
or
2) Refresh only that data where user was. So this is basically how it works on expanding, gets data and adds to parent, but I would want this behaviour on refresh and leave user row selection as it was.
Additional notice:
When you filter treeGrid for exmaple with menu filter. Then expanding one of the rows, the data gets duplicated.
Sequence:
1) Filtered treeGrid with menu filter where value is "test". The result I got:
2) And when I'm expanding "test" row it gets data to child and to main grid, so it gets duplicated:
