Dynamic TreeGrid

[alarcher]

Hello folks,

Do you know if there is a simple way to create a TreeGrid that dynamicaly loads the data as long as you browse the tree ?

I may call a server method on each onFolderOpened event, but this leads to a graphical bug : the new data is correctly loaded but I need to click twice on the node in order to expand it.

Is there a better solution, for example by using a server datasource ?

Any help will be appreciated,
Thanks a lot.

Hi,

Check this example out:
http://www.smartclient.com/smartgwt/showcase/#featured_tree_grid

But pay attention to the line

 treeGrid.setLoadDataOnDemand(false);

You should change it to "true" to have one request per open "folder". Otherwise, you should retrieve all data in one request.

Hope this helps!

Hi,

I would appreciate if you can point me to the source code of the same.
I couldn't find it in the zip file I downloaded (Smartgwt 2.5 nightly build).

Thx,
