推荐答案

这是我们努力保持的东西远离：它强迫用户按照现代用户非常极少的顺序工作。



为网络执行此操作的正常方法形式会b e有多个页面，因此第一个按钮创建一个具有第二个按钮的新显示，依此类推。想想你真正需要的方式 - 在购物网站上首次购买：

第一页：电子邮件和密码

第二页：地址确认/输入

第三页：付款细节

第四页：承诺购买。

每页都有一个后退按钮。



你不是在一个页面上这样做（因为它令人困惑）所以为什么你的任务会有所不同？应用程序控制用户处理页面的顺序的程序输入现在非常非常罕见。

That's something we try very hard to stay away from: it "forces" the user to work in a sequence which very, very few modern users do these days.

The normal way to do this for a web form would be to have multiple "pages" so the first button create a new display that has the second button, and so on. Think of the way you do this when you really have to - a first purchase on a shopping site:
Page one: email and password
Page two: address confirmation / entry
Page three: payment details
Page four: commit to buy.
And each page has a "back" button.

You don't do this on a single page (because it's confusing) so why would your task be any different? Procedural inputs where the app controlled the order in which the user handled a page are very, very rare these days.

您可以在网页中使用Mulltiview控件，其中您可以拥有3个视图和每个视图都有一个按钮。点击按钮，它将切换到下一个视图。作为参考，您可以参考下面的多视图示例。

You can use Mulltiview control in your webpage, Where you can have 3 Views and each view will have a button. On click of button it will switch to next view. For reference you can refer below multi view example.

i have used following solution
on Page_Load set
button2.visible = false;

button3.visible = false
 and when function of button1 is completed then it call 
button2.visible = true;
same as above and when function of button2 is completed then it call 
button3.visible = true;
