Question

I am working on JQuery AutoComplete on my ASP.NET page. And, I am using ashx file to populate list.

But, the ashx looks like it’s not firing. I am not sure what I am doing wrong.

jQuery code

$(function () {
    $("#<%=txtBox.ClientID%>").autocomplete('MyList.ashx', { minChars: 1 });
});

.ashx code

[WebService(Namespace = "http://www.yoursite.com/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] 
public class MyList: IHttpHandler
{ 
    public void ProcessRequest(HttpContext context) {
        //Just to test
        context.Response.Write("test");
    }
}

Answer 1

Set MIME content-type for the ashx to return json data.

Response.ContentType = "application/json";
Response.Write("['Content1', 'Content2']");  //consider using JsonSerializer

Also, specify json as the data type for the source to autocomplete.

$("...").autocomplete('MyList.ashx', { dataType: "json" });
