推荐答案

将此代码与您自己的按钮ID一起使用

Use this code with your own button id

(this.Page.Master.FindControl("btnRegister") as Button).Visible=false;

try:

try:

Button myButton = (Button) Master.FindControl("buttonId");
if(myButton != null)
{
    myButton .Visible =false;
}

最好的方法是在母版页上拥有一个公共属性.此属性可以更改控件的可见性，并且您可以有条件地从子页面使用此属性.

参见以下示例:
在我的母版页中有(RightSide 是我的母版页中的面板的名称)

The best way to do this would be to have a public property on the master page. this property can change the visibility of the controls and you can use this property from child pages conditionally.

see this example:
in my master page i have (RightSide is name of a Panel in my master page)

   public bool SidePaneVisibility
   {
   get
   {
    return RightSide.Visible;
   }
   set
   {
      RightSide.Visible = value;
   }
}

而且我在内容页面上有条件地使用它:

and I am using it from my content page conditionally as:

if (Session["UserId"] == null)
          {
              MasterPage master = (MasterPage)this.Master;
              master.SidePaneVisibility = false;
          }
