I also have not been able to get the async portion of jquery TreeView
plug in working in ASP.NET. My WebMethod is returning data just
fine. Not sure what I'm doing wrong. I can call my WebMethod just
fine outside of the treeview...
// var x = $.ajax({type:"POST",
// url: "SearchResults.aspx/GetData",
// data: "{}",
// contentType: "application/json; charset=utf-8",
// dataType: "json"
// });
//alert(x);
But when I try to do something like this, it doesn't call my method.
$("#navigation").treeview({
persist: "location",
collapsed: true,
unique: false,
ajax: {
url: "SearchResults.aspx/GetData",
type: "POST",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success:function(json){x=json;}
}
});
