Dear forum members,
I am faced by the below problem, and I am not able to figure out what can be done to resolve it.
There are two TreeGrids on a page, which support drag and drop between them. As these Treegrids are datasource bound, whenever I perform any drag and drop, these changes are propogated to the database and are saved.
But what if I committed some mistake, by appending node to a wrong parent, what can I do to undo those changes, without having to manually perform the reverse drag and drop?
or
How to implement a mechanism, such that when I am convinced by my changes, I click the save button and these changes are sent to the database?
Added to the fact that trees in my applications are quite large, so I need to use the loadOnDemand feature of TreeGrids
Could anyone please provide some direction to me?
Should you have any queries then please do let me know.
Note: I am using NetBeans IDE 6.8, GWT 2.0.3 and SmartGWT 2.1, Firefox 3.6.3
Kind regards,
Hardik Raja
