您可以参考下面的代码片段。

using System;
using PX.Data;
using PX.Objects.CR;

namespace PXDemoPkg
{
    public class CRCaseMaintPXDemoExt : PXGraphExtension<CRCaseMaint>
    {
        public override void Initialize()
        {
            if (Base.Actions.Contains("NewActivity"))
            {
                PXButtonState actionsMenuState = Base.Actions["NewActivity"].GetState(null) as PXButtonState;
                if (actionsMenuState != null)
                {
                    foreach (ButtonMenu button in actionsMenuState.Menus)
                    {
                        button.Visible = false;
                    }
                    actionsMenuState.Visible = false;
                }
            }
        }
    }
}
