How to extend the TreeView to create a HierarchicalTreeView RRS feed

  • Question

  • User-1887867400 posted

    Hi need some directions regarding how we can extend a TreeView control and change its appearance to look like a hierarchical tree structure (or binary tree)? so that it can be used for generating a MLM tree from the database with clickable nodes.

    Hi Vijay,

     

    You cannot derive the "TreeView" control for the change of it rendering style because its "TreeNodeCollection" is sealed one which in-charge of Saving/recreating all "TreeNodes" to/from viewstate. So better, you can derive from the "DataBoundControl" and define your own way of Rendering "HierarchicalTreeView".

    Hi Vijay,

    You can get excellent sample from this link.

    http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.hierarchicaldataboundcontrol.aspx

    Here they have also listed the Member and Methods available. Example is given in last section.

    Hi all thanks for replying.

    But the problem is that, this msdn link just lists the api for HierarchicalDataBoundControl but i'm looking for a complete sample that implements the UI of the control like a Binary Tree. Something like this. And each node can hold some controls there.

    The nodes not necessarily needs to be round but should be able to hold other controls as well.
