[英]Hide edit button on Page_Load
I am trying to hide the Edit button when a student logs in and show it when the admin logs in. By default the edit button is visible.我试图在学生登录时隐藏“编辑”按钮,并在管理员登录时显示它。默认情况下,编辑按钮是可见的。 I want to hide the edit button on Page_Load.我想隐藏 Page_Load 上的编辑按钮。 I have tried wrapping it in a div but it does not work for some reason.我曾尝试将它包装在一个 div 中,但由于某种原因它不起作用。 Any solutions??有什么解决办法??
