There are client APIs to know when data is being requested or when the user clicks the search button but I haven't found any examples of calling an external web service (using JQuery for example) and adding the search results using a client method. Does the search box support this?
The TreeView for example supports adding RadTreeViewNodes programmatically after querying an external "ado.net web service" as you call it in your documentation. I would like to be able to this with the RadSearchBox as well: manually query an external web service then add the results to the dropdown.
