Hello all.

I have about 700 buttons in my aspx. All buttons will do the same event so I want to declare only one buttonclick event so that all buttons will fire to that only event. How can I do that?

Tq!

推荐答案

您可以声明任意数量的按钮并分配1个onclick函数:)


经过测试的4个按钮

You can declare as many buttons you want and assign 1 onclick function :)


Tested for 4 buttons

<asp:Button ID="btn1" runat="server" Text="btn1" onclick="btn1_Click" />
    <asp:Button ID="Button1" runat="server" Text="btn1" onclick="btn1_Click" />
     <asp:Button ID="Button2" runat="server" Text="btn1" onclick="btn1_Click" />
      <asp:Button ID="Button3" runat="server" Text="btn1" onclick="btn1_Click" />

定义单个按钮单击事件处理程序并将该处理程序附加到所有按钮.

Define a single button Click event handler and attach that handler to all the buttons.

btn1.Click += new EventHandler(this.GenericBtn_Click);
btn2.Click += new EventHandler(this.GenericBtn_Click);
btn3.Click += new EventHandler(this.GenericBtn_Click);
btn4.Click += new EventHandler(this.GenericBtn_Click);
.
.
.
btnn.Click += new EventHandler(this.GenericBtn_Click);

void GenericBtn_Click(Object sender, EventArgs e)
{
  // all button clicks land here!
}
