推荐答案

使用javascript或服务器端事件

见下面的片段

Use javascript or server side event for it
see below snippet

<script labguage="javascript">
function enableDisable(objID)
{
  //check if login is clicked then make logout disable
  if (objID == "btnLogin")
  {
     document.getElementById("btnLogin").disabled = true;
     document.getElementById("btnLogout").disabled = false;
  }
  else //if logout clicked
  {
     document.getElementById("btnLogin").disabled = false;
     document.getElementById("btnLogout").disabled = true;
  }

}
</script>
//call above javascript function on button click
<asp:button runat="server" id="btnLogin" text="Login" onclientclick="return enableDisable(this.id)"  />
<asp:button runat="server" id="btnLogout" text="Login" onclientclick="return enableDisable(this.id)"  />
