In order to define the hierarchical structure needed for the tree it's necessary to provide a nested array of JavaScript objects. At the lowest level a tree node is a represented as a simple JavaScript object. This one required property text will build you a tree.

The following properties are defined to allow node level overrides, such as node specific icons, colours and tags. For simplicity we directly leverage Bootstraps Glyphicons support and as such you should provide both the base class and individual icon class separated by a space.

By providing the base class you retain full control over the icons used. If you want to use your own then just add your class to this icon field. Whether or not a node is selectable in the tree. False indicates the node should act as an expansion heading and will not fire selection events.

Used in conjunction with global showTags option to add additional information to the right of each node; using Bootstrap Badges. You can extend the node object by adding any number of additional key value pairs that you require for your application. Remember this is the object which will be passed around during selection events. Options allow you to customise the treeview's default appearance and behaviour. They are passed to the plugin on initialization, as an object.

You can pass a new options object to the treeview at any time but this will have the effect of re-initializing the treeview. String, any legal color value. Default: inherits from Bootstrap.

Each Tree View node is represented by a BootstrapTreeViewNode object and provides access to a collection of its sub-nodes through the Nodes collection property. The Tree View control supports selection of nodes with a mouse click.

Note that only one node can be selected at a time. Handle the client ItemClick or server ItemClick event to detect a selection change. You can identify the clicked item by the value of its Name property. Moreover, the Tree View control can automatically select an item for a current page. You can control this behavior using the SyncSelectionMode property. The Tree View control can obtain its node from the server as needed using callbacks. When this mode is activated, the contents of collapsed nodes are not present on the client until these nodes are expanded.

To specify whether to use the callback technology to transfer node data to from server, use the EnableCallBacks property. Note that in this demo the callback time is intentionally extended so that the loading indicator is visible during callbacks.

Collapsing and expanding actions will remain available for end-users via a mouse double click. To prevent these actions, subscribe to the client-side ExpandedChanging event and set e. The TreeView can display supplementary information for any node within a badge. A badge can display a text, an icon or both.

Use the following API to configure badges on the server side:. Note that the BootstrapTreeViewNode. Badge property does not affect templated nodes. A data-bound Tree View automatically creates a node for each data item. A created node obtains values for its properties from data item attributes with matching names. You can also explicitly specify mappings between node properties and names of data item attributes using the following properties.

When the Tree View control is functioning in Virtual mode, child nodes are created and initialized only when their parent node is expanded. In the event handler, programmatically create a list of BootstrapTreeViewVirtualNode objects representing child nodes for the currently expanded node. For each created node that has no children, set the IsLeaf property to true so that the node does not display the expand button.

The Tree View control supports templates allowing you to customize control appearance and layout. A template can be applied to all nodes using control level templates or a specific node using node level templates. Use the following properties to specify templates. BootstrapTreeView properties:. NET Framework. DevExpress ASP. NET Controls and Libraries for the. DevExpress Document Server for the. This demo illustrates the capabilities of the Tree View control's client events and allows you to specify which client-side events you want to track.

Interact with the Tree View interface to see the information about all tracked events raised in response to your actions in the event log. The Tree View control offers an advanced client-side API allowing you to manipulate the control and its elements. Note that the client-side API is automatically enabled if the ClientInstanceName property is specified or any client-side event available through the ClientSideEvents property is handled.

This demo allows you to interactively explore capabilities of the Tree View control's client-side API. BootstrapClientTreeView methods:. BootstrapClientTreeViewNode methods:.The article submission wizard is messing around with my Code Dowload link, so here is the code in GitHub:.

Please ignore the FancyTree project in the source. That is an article in early progress and will feature here very soon. The user needs to select a folder for backup to another location. JQuery and family have plenty, and one that deserves honourable mention is jQuery FancyTree. It is, of course, also free and open source.

My adaptation of this widget for my folder browser is far from feature perfect and has some drawbacks, but it was very quick and easy to implement, it works, and it allows me to choose a folder, the only real requirement here.

This part of the article covers setting up a treeview to show file system data. At the end of this part, you should be able to create a web page on which people can browse folders. Once the important stuff is out of the way, in Part 2I will show you how to package up all this cool into a new Folder Browser widget, with more features and more reusability.

This is as simple as downloading or installing Bootstrap Treeview and referencing scripts and styles in your view or layout page. The package is available via npm and boweror you can clone or download the whole repo from github. My style references for this project, for the Development environment, look like below.

I always try and use non-minified files for development, but there is no non-minified file is this case:. I also only normally use non-minified scripts for development, except when not available, like here.

Bootstrap Treeview

Place a container and script on your view, ideally a divin which the Treeview must appear:. The Bootstrap Treeview is very simplistic but tricky. It requires the tree graph data to be ready before you initialize the Treeview. The fact that we must have the data before initializing the widget means we can do the initialization of the treeview in the done jQuery Ajax method or equivalent :.

My simplified node class, TreeNodeis designed to represent a tree node, and is a very small subset of the full specification for a node object, as seen on the home page for the widget, under the heading Data Structure. No other icons are visible on the online examples either, so I chose to omit the icon properties totally, to keep things as small and tidy as possible. This treeview requires a recursive data structure JSON to represent a whole folder tree as the widget does not support lazy loading, or any Ajax beyond the initial load.

It, therefore, needs all the data at once. I find this unnerving, because nesting is rife on a filesystemto who knows what depth, and building and transferring huge JSON documents only hurts performance. I think the above code is readable, given we know its exact purpose, so no more explanation is required.

Bootstrap Tree View

It seems ideal to have a browsing root, set to a file system folder, that the user cannot browse beyond. They can, using relative paths, but the complexity of checking these paths is beyond the scope of this simple exercise. I have a config setting called BaseDirwhich is the path to where the root of the treeview must begin. The Path. Combine in the controller code helps establish this as the root for the treeview. If you have followed along this article together with the official documentation for the Bootstrap Treeviewyou should easily be able to put together, if not a real browser widget, at least a page e.

In the second and last part of this article, I will show you how to use your code to build a proper, reusable widget that can be plugged in anywhere you need folder picking or browsing.A simple and elegant solution to displaying hierarchical tree structures i.
