@ Data_Binding : From server side we are passing xml to client side. Is there any way to bind that xml data to CellTree so that all data populated/render in CellTree (In Tree format) like.. In smartGwt http://www.smartclient.com/smartgwt/showcase/#featured_tree_grid ==> Source code ==>see EmployeeXmlDS.java # Created data source set to TreeGrid #1 Create dataSource : specify dataUrl (data in xml format) & setRecordXPath etc.. and set created DataSource in TreeGrid
BUT I dont want to use SmartGwt ( :( Its not free) . I want to use GWT. In GWT,: How to populate a CellTree with xml data which is coming from server side >From server side we are passing xml to client side. Is there any way to bind that xml data to CellTree so that all data populated/render in CellTree (In Tree format) @ Sorting ? Or Is there any Tree widgets (from Open source) which provides Sorting, Filtering, DataBinding On Apr 5, 1:13 pm, Thomas Broyer <[email protected]> wrote: > On Thursday, April 5, 2012 8:54:03 AM UTC+2, vaibhav gwt wrote: > > > I want to render large tree dynamically so I selected CellTree widget. > > I also want to know How CellTree widget supports DataBinding, > > CellTree, like all Cell widgets, is *based* on databinding (unless you > don't have the same definition for databinding as me) > > > Sorting & filtering etc.. ? > > It doesn't support those features, but your model (TreeViewModel) can (most > likely using a *decorator* pattern around you *real* TreeViewModel).
