Cannot find any bindable properties in an item from the datasource

[Ozzie]

Hello!

I receive the error Cannot find any bindable properties in an item from the datasource when I try to achieve client-side databinding with the help of a webservice.
I use one class to handle all calls to my stored procedures. They return a DataTable. When I use these calls in RadGrid1_NeedDataSource() to bind data with RadGrid1.DataSource = myClass.GetDataTable(); it works fine.
But when I place the same call in a WebService and use that Webservice in my javascript functions it does not.

in myService.cs:
[WebMethod]
public DataTable bindData()
{
   return myClass.GetDataTable();
}

my javascript:
function pageLoad(sender, args)
{
    setInterval("myService.bindData(updateGrid)", 1000);
}
function updateGrid(result)
{
     //var grid = $find("<%= RadGrid1.ClientID %>");
     //grid.DataSource = result;
     var tableView = $find("<%= RadGrid1.ClientID %>").get_masterTableView();
     tableView.set_dataSource(result);
     tableView.dataBind();
}

In my RadGrid I use an ItemTemplate.

Hi Ozzie,

The JSON serializer doesn't support data table objects, so you can't get them through the web service. You have to use an alternative datasource object.

Hope this helps.
