    Hello Thanh,

    Thank you for writing.

    I managed to reproduce the issue and I added it to our public issue tracking system. We will address it in a future release.

    In the meantime, you should create a custom multicombo box control to address the issue:
    public class CustomMCCB : RadMultiColumnComboBox
    {
        public override string ThemeClassName
        {
            get
            {
                return typeof(RadMultiColumnComboBox).FullName;
            }
            set
            {
                base.ThemeClassName = value;
            }
        }
     
        protected override RadMultiColumnComboBoxElement CreateMultiColumnComboBoxElement()
        {
            return new CustomMCCBElement();
        }
    }
     
    public class CustomMCCBElement : RadMultiColumnComboBoxElement
    {
        protected override Type ThemeEffectiveType
        {
            get
            {
                return typeof(RadMultiColumnComboBoxElement);
            }
        }
     
        protected override void ProcessTextKeyUp(object sender, System.Windows.Forms.KeyEventArgs e)
        {
            if (e.KeyCode == Keys.Tab ||
                e.KeyCode == (Keys.Tab | Keys.Shift) || e.KeyCode == Keys.ShiftKey)
            {
                return;
            }
     
            base.ProcessTextKeyUp(sender, e);
        }
    }

    I updated your Telerik points.
