ComboBox store reload in beforeQuery problem

[Vinci]

Actually this thread is related to my other post.

I want to do a custom search of combobox by reload store in BeforeQuery event.

In code behide

 cbo.Listeners.BeforeQuery.Handler = "beforeQuery(this);";

In JS

function beforeQuery(sender) {
    sender.lastQuery = null;
    var q = sender.getRawValue();
    sender.loaded = true;
    sender.store.reload({ params: { search: q} });
    sender.cancel = true;
}

The problem is every time I input, the store is reloaded twice.

One is from beforeQuery that defined by me, and other I think is happen in doQuery.

And the reload in doQuery cannot get correct result.

I try to disable the doQuery by inserting sender.cancel = true; at last line, but it does not work.

How can I disable doQuery? Thanks!

Hi @Vinci,

I don't think you need to reload a Store manually.

If a ComboBox QueryMode is Remote (it is by default), when a ComboBox reloads its Store sending typed text as a parameter.

Thank you. I get rid of the BeforeQuery.Handler
and get the query string by HttpContext.Current.Request.QueryString["query"] in the according .ashx.

Know it run fine.
