Hello All,

How to disable page buttons or the page itself during postback(in asp.net with c#) so that the user will not be able to click buttons in between data processing?

The button or page should be disabled on button click and will get enabled after data processing with error or success message.

Thank you..!!

What I have tried:

on button click:

btnSave.Enabled = false;
     btnSubmit.Enabled = false;
     btnLogout.Enabled = false;

操作后，错误/成功消息之前：

And after operation, before the error/ success message:

btnSave.Enabled = true;
     btnSubmit.Enabled = true;
     btnLogout.Enabled = true;

这是正确的方法吗？因为即使将值设置为false后按钮也可见并且可点击。

Is this the right way? Because the buttons are visible and clickable even after setting value to false.

兄弟...你很幸运，有一个现成的解决方案可用一点点的javascript

ASP.NET导出Excel - 显示/隐藏加载图像 [ ^ ]

通过这些链接，最好是你要来的第一个知道逻辑。

Go through these links preferably the first one you will come to know about the logic.

试试

try

<asp:Button Text="text" ID="btnTest" OnClientClick="disableAllButton();" runat="server" OnClick="btnTest_Click" />

function disableAllButton() {
           var buttonsToDisable = [];
           buttonsToDisable.push(<%=Button1.ClientID%>);
           buttonsToDisable.push(<%=Button2.ClientID%>);
           buttonsToDisable.push(<%=Button3.ClientID%>);
           buttonsToDisable.push(<%=btnTest.ClientID%>);
           for (var i = 0; i < buttonsToDisable.length; i++) {
               buttonsToDisable[i].disabled = true;
           }
       }
