[Solved] ComboBox Rebind on Open?

[Sean]

I have a number of form fields that I bind that are dependent on other field values. Is there some way to tell the ComboBox to rebind every time it is opened? In this example if someone changes the State, the zip codes in the list are no longer valid.

function

 

 

Zip_AutoComplete(e) {

 

 

    e.data = $.extend({}, e.data, { state: $(

 

"#State").val(), city: $("#City").val() });

 

 

}

 

 

@(Html.Telerik().AutoComplete()

 

.Name(

 

 

"Zip")

 

 

.Encode(

 

 

false)

 

 

.Filterable(f => f.FilterMode(

 

 

AutoCompleteFilterMode.Contains))

 

 

.HighlightFirstMatch(

 

 

true)

 

 

.ClientEvents(events => events.OnDataBinding(

 

 

"Zip_AutoComplete"))

 

 

.DataBinding(a => a.Ajax().Select(

 

 

"ZipList", "Rat"))

 

 

.AutoFill(

 

 

true)

 

 

.HtmlAttributes(

 

 

new { style = string.Format("width:{0}px", 90) })

 

 

)

public ActionResult ZipList(string text, string state, string city) {

 

 

 

 

 

    var zips = _entities.Locations.Where(l => l.State == state

 

 

        && (city.Length == 0 || l.City.StartsWith(city)))

 

        .Select(l => l.ZipCode).Distinct()

 

        .OrderBy(o => o)

 

        .ToList();

 

 

 

 

    return new JsonResult { Data = zips };

 

 

}

I think this is a valid question, found any solution to it? I'm surprised no one from the Telerik Team helped.
