jQxTree(load on demand) from database

[fakharMember]

Hi…. I am working in ASP.Net MVC. I have used jqxtree plugin into my view. I have to make jqxtree ajax-supported i.e. i want its functionality of “Load on Demand”. I have maintained a database whose schema is somehow as: ID , Label, ParentID.
I want a node to be filled by its children when it is expanded. Please help me in this regard that how to find ID of expanded item, receive data (ID & Label) from server and add it to tree using ajax. Please help.

Hi,

Have you looked at that sample: http://www.jqwidgets.com/jquery-widgets-demo/demos/jqxtree/ajaxloading.htm?web? In the sample, the Tree nodes are loaded through Ajax. A dummy node – “Loading…” is added to each tree node so the Expand Arrow is displayed. When the node is expanded, the Tree makes an Ajax request and dynamically adds the sub nodes and also removes the “Loading…” node. I believe the same approach could be used when working with DB as a data source. However, the difference would be that the Ajax requests should point to your server code which should return the appropriate Nodes formatted in the same way as in our sample.
