Refresh TreeGrid and preserve open & selected state ?

[markok]

Hi,

What is the correct way to refresh an already loaded TreeGrid and preserve the open & selected state of the tree ? When calling invalidateCache there is no callback code available to do custom getOpenState & setOpenState as in the initial fetch when calling fetchData(...).

Or - is there a api method available to mark the cache of data bound component's resultset to invalid so that consequent fetchData call on component would always trigger a server fetch ?

br,
Marko

That would be great!

I'm also now looking for a solution to this problem, but for GridList. I need to update one column with the prices.

You may take a look at the ds.updateCaches(changeResponse, changeRequest);
But you have to fetch data yourself, grab DSResponse and feed updateCaches with it.
