Web Dev Update: ASP.NET Templates – YUI 2 – Grails

I’m going to combine these two short comments together

ASP.NET MVC 2 Templates

Brad Wilson does a good job explaining some features of the asp.net mvc 2 templates:



YUI – Treeview and Datatable Together

Carlos Bueno blogs about the YUI 2 features of linking a treeview and datatable together:


Carlos was kind enough to email me a response on using this with asp.net mvc.  Here is the snippet:

You create an AJAX endpoint that returns data in the format described in that link. 
Then instead of a static javascript datasource, you instantiate a json data source 
and give it the URL to pull from:

var myDataSource = new YAHOO.util.DataSource("/foo/bar/some-data");
myDataSource.responseType = YAHOO.util.DataSource.TYPE_JSON;

To change the URL (and thus refresh the table) you would call datasource.sendRequest() 
with a new querystring, like so:

var requestString='QUERY=’ + some_query + ’&sort=timestamp&dir=asc&startIndex=0&results=25';
var oCallback = {
  success : myDataTable.onDataReturnSetRows,
  failure : myDataTable.onDataReturnSetRows,
  scope   : myDataTable,
  argument: myDataTable.getState()
myDataTable._oDataSource.sendRequest(requestString, oCallback);
