public void SetDropDownSettings()

    // Creates an instance of a GcMaskedComboBox control.
    GcMaskedComboBox gcMaskedComboBox1 = new GcMaskedComboBox();

    // Sets the AllowResize to true, you can change the size of drop-dwon window by drag the mouse.
    gcMaskedComboBox1.DropDown.AllowResize = true;
    // Sets the ClosingAnimation to Fade, the drop-down window will displayed as a fade effect when it's closing.
    gcMaskedComboBox1.DropDown.ClosingAnimation = DropDownAnimation.Fade;
    // Sets the OpeningAnimation to Fade, the drop-down window will displayed as a fade effect when it's opening.
    gcMaskedComboBox1.DropDown.OpeningAnimation = DropDownAnimation.Fade;
    // Sets the Dirction to AboveLeft, the drop-down window will displayed above the control and align to left.
    gcMaskedComboBox1.DropDown.Direction = DropDownDirection.AboveLeft;
    // Sets the ShowShadow to true, the drop-down window will displayed with a shadow.
