    I am not sure what assistance do you need. Exception text gives clear instruction, define reader in proxy only (if proxy is defined)

    You code from the first post has reader adding to the proxy already. Just somewhere you add a proxy to the store directly (to Reader collection of the store). You need avoid it (reader must be added to proxy only)

    Please see the below code

    </div>
</body>

        {
            this.QueryMode = DataLoadMode.Remote;
            this.TriggerAction = TriggerAction.All;
            this.MinChars = 1;
            this.PageSize = 10;
            this.TypeAhead = false;

            var reader = new Ext.Net.JsonReader();
            var model = new Model();

            model.Fields.Add("fullName");
            model.Fields.Add("active", ModelFieldType.Boolean);
            reader.Root = "data";
            reader.TotalProperty = "total";

            var proxy = new Ext.Net.AjaxProxy();
            proxy.ActionMethods.Read = HttpMethod.POST;
            proxy.Url = this.getProxyUrl();

            var store = new Ext.Net.Store();

    1. You have to add the reader to the proxy instead to the store

    Remove
    store.Reader.Add(reader);
    Add
    proxy.Reader.Add(reader);
    2. Ajax request cannot be cross domain. Url must point to the same domain (page's domain)
