How to use Treeview IE Web Control

The first step is to install the IE Web Controls from Microsoft.The link to download and
install these controls is as follows: http://msdn.microsoft.com/downloads/samples/
internet/default.asp?url=/downloads/samples/internet/asp_dot_net_servercontrols/webcontrols/default.asp

The next step is to add a reference to the controls on your page:
<%@ Register TagPrefix=”mytree” Namespace=”Microsoft.Web.UI.WebControls”
Assembly=”Microsoft.Web.UI.WebControls” %>;
<%@ import namespace=”Microsoft.Web.UI.WebControls” %>;
Then you add the TreeView control to your page:


The last step is to add the node information to the TreeView.This is the list of items that
will appear when you expand the tree:
<mytree:treeview runat=”server” id=”myTree”>
<mytree:treenode text=”Cars”>
<mytree:treenode text=”Ford” />
<mytree:treenode text=”Toyota” />
<mytree:treenode text=”Infiniti” />
</mytree:treenode>
</mytree:treeview>

Here, we created one node called Cars and then added nodes within that node for different
car manufacturers.

The TreeView IE Web Control is a very powerful and easy-to-use control. In this example,
you saw how easy it was to create an explorer-like expandable tree.When adding
nodes to the TreeView, you use a very XML-like approach whereby the nodes that are
under a parent node are contained inside the parent node tag. If you encounter errors
when trying to add a reference to your page, or you receive errors indicating that the
Web Controls cannot be found, copy the Web Controls DLL to the bin directory of
your application.
