Just set the Value and Display properties of the anonymous object from values in your datatable using dt["ColumnName"]

$.each(msg.d, function(index, item)

But I had to coded like this

$.each(eval(‘(‘ + msg.d + ‘)’), function(index, item)

Because otherwise item would return and array with size of the total of characters in the msg.d string; therefore giving me item.Value and item.Display as undefined

Do you know why this happens? I’m making a web application on VS 2010 (framework 4), in my web method (the one that is called via Ajax) I serialize a List whit the JavaScriptSerializer object. I don’t know if this has something to do with it

It won’t be visible when you view source as it’s loaded into the DOM via ajax.

For showing the combo after population you could initially add a display:none style to it, then in the ajax callback use jQuery.Show to display it.

1. Why option tag not visible under select tag when I do View Source on the IE even if the values have been filled in combo-box successfully.
2. I need to hide the combo-box when page loads and then need to display when the comb-box is populated through Ajax call.

Where are you seeing msg.d?

Joe

My example uses an ArrayList, you can easily swap it out for a generic list.

SQL Server won’t be giving you a generic list, it’ll be whatever ORM/data access method you’re using. With my example you need a web service method that returns the data you get from the database.

$(‘#>option’).remove();
$(“#”).append($(”).val(‘-1′).html(“–Select One–”));

i tried following code for that also

$(‘#drpGenderHobby).empty().append(‘-All-’).find(‘option:first’).attr(“selected”, “selected”);

but in my case it is not working fine..
i also tried your give way

$(“#ddlName”).get(0).options.length = 0;
$(“#ddlName”).get(0).options[0] = new Option(“Select name”, “-1″);

but in this case i am not getting desire output

looking for positive reply

thanks in advance.

Taking it a step further, I cleaned it up, by using something like:

$(‘#ddlName’).empty().append(‘Loading Names’);

And used:

$(‘#ddlName’).append(” + item.Display + ‘</option');

In the for loop.

The Webservice you create should be using the Name Space System.Web.Script.Services; [ScriptService] attribute has to be added.

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ScriptService]
public class MyService : System.Web.Services.WebService
{

Not really sure without seeing it. Have you got all the necessary using statements?

Thanks for this, it’s just what I’m after. The only problem is I am having trouble compiling.

I’m working in Visual Web Developer 2008 Exp and have .net 3.5 installed. I can compile your sample code but as soon as I try to compile an exact copy of your web method in my code it comes up with around 45 errors all asking for ‘;’s or type expected etc… in and around the web method. Have you any ideas what may be causing it?
