Levure helper for creating a file browser control in your application

File Browser Helper

The File Browser helper is an example of a helper that extends the DataView Tree behavior. It will list the folders and files of a root folder and allow the user to drill down into the contents of sub-folders.

This helper includes a behavior script that can be assigned to a DataView. When in use the behavior chain of the DataView group control is as follows:

File Browser DataView Tree Behavior > DataView Tree Behavior > DataView Behavior

The helper includes the row templates necessary for display files and folders.

Note that this helper requires the DataView Tree helper and DataView helper.

Demo
