Multicolumn TreeGrid implementation with json data

[preeti_kanyal]

Hi Isomorphic Team,
We are using the ismorphic version : 6.1-p20170930
my current functionality uses SmartGWT + Spring Rest services.
We are using Google chrome browser latest version.

I want to implement TreeGrid to display hierarchical data (Data looks similar to Windows file system structure. FolderA -> FolderB ->FolderC ->File.txt)
In front of all the leaf nodes (.txt files ) i want to provide a user clickable icon (say favorite icon)

I thought to implement my TreeGrid as multi column grid and add icon to one of the TreeGridField.
But i could see all the multi column examples in showcase using DataSource.
As stated above my functionality will get the tree data as json from a Rest service.

Could you please provide any example of multiColumn TreeGrid without dataSource.?
or suggest any other way to achieve the same?

Hi,

please see the showcase and search for "REST". Without having used it myself, I'd assume that TreeGrid + RestDataSource connecting to your service will solve this for you.

Best regards

You seem to think that multicolumn is in some way related to use of DataSources - it isn't. Please revisit the QuickStart Guide, Data Binding chapter. TreeGrid and other DataBoundComponents can be configured with multiple fields regardless of whether a DataSource is involved.
