动态创建一个按钮，但它不会触发（ASP.NET） [英] Created a button dynamically but it doesnt fire (ASP.NET)

问题描述

您好。我设法在面板中动态创建一个按钮，并分配了一个单击时触发的功能。好的，我可以在面板中看到按钮但是当我点击时，功能不会触发。 （实际上按钮也消失了。）这是代码：

按钮eklemeButonu = new Button（）; 
 eklemeButonu.Text =添加; 
 eklemeButonu.ID =eklemeButonu; 
 eklemeButonu.Attributes.Add（runat，server）; 
 eklemeButonu.Click + = EklemeButonu_Click; 

 Panel2.Controls.Add（eklemeButonu）; 
 

 private void EklemeButonu_Click（object sender，EventArgs e ）
 {
 //显示消息
} 
 

什么我试过了：



放runat server属性和其他一些属性。但是没有用。

解决方案

应该在每个回发上重新创建动态生成的控件，以便将它们保留在页面上。请参阅：

谢谢你的回答。我更擅长Windows窗体，所以我不会使用asp。

Hi. I managed to create a button dynamically in a panel and assigned a function to fire when clicked. Ok i can see the button in the panel but when i click, function doesnt fire. (Actually button vanishes too.) This is the code:

Button eklemeButonu = new Button();
            eklemeButonu.Text = "Add";
            eklemeButonu.ID = "eklemeButonu";
            eklemeButonu.Attributes.Add("runat", "server");
            eklemeButonu.Click += EklemeButonu_Click;

Panel2.Controls.Add(eklemeButonu);

private void EklemeButonu_Click(object sender, EventArgs e)
       {
            //show message
       }

What I have tried:

put "runat server" attribute and some other attributes. but didnt work.

解决方案

Dynamically generated controls should be recreated on each postbacks to retain them on the page. See:

ASP.Net Persist Dynamic Controls: Dynamic Controls disappear after PostBack in ASP.Net
