Hi, guys!

this is my combobox setting:
            cbo.TriggerAction =TriggerAction.All;//  TriggerAction.Query;
            cbo.DisplayField = "DSP";
            cbo.ValueField = "VAL";
            cbo.Mode = DataLoadMode.Remote; //DataLoadMode.Local;
            cbo.LoadingText = "Searching..."; 
            cbo.Editable = true;
            cbo.ItemSelector = "tr.trSelectBoxBody";
            cbo.SelectOnFocus =false ;
            cbo.ValidateOnBlur = true;
            cbo.ValidationEvent = "blur"; 
            cbo.MinChars = 4;
            cbo.Validator="comboValidating"; 
            cbo.Listeners.BeforeQuery.Handler = "beforeQuery(this);";           
            cbo.MsgTarget = MessageTarget.Side;
            cbo.QueryDelay = 300;
it works fine.
But the only question is combobox will do query everytime when i input some text. I hope it do query only when I press its triggerbutton. any setting can help me solve it? Thanks.
