I have some Html code that contains the button tag "<button></button>".
I have noticed that if I place a linkbutton inside this element, the postback of the linkbutton will never occur.
So this is not working :
<button><asp:LinkButton ID="lnkExample" OnClick="lnkExampleBtn_Click"runat="server">Text</asp:LinkButton></button>
The server method "lnkExampleBtn_Click" will never be launched.
How come the postback doesn't work ?
Is there a way to have a linkbutton work inside the "button" tag ?
I also tried putting an href element with javascript _doPostback specific method, but that is not working either.
I've tried to reproduce your case.
Here's code behind:
public partial class Test : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btnTest_Click(object sender, EventArgs e)
{
lblTest.Text = "Test";
}
protected void btnTest2_Click(object sender, EventArgs e)
{
lblTest.Text = "Test2";
}
}
And here's aspx:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Test.aspx.cs" Inherits="WebApplication1.Test" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:LinkButton ID="btnTest" runat="server" OnClick="btnTest_Click">Test</asp:LinkButton>
<button><asp:LinkButton ID="btnTest2" runat="server" OnClick="btnTest2_Click">Test2</asp:LinkButton></button>
<button><a href="http://www.google.com/">test</a></button>
<asp:Label ID="lblTest" runat="server"></asp:Label>
</div>
</form>
</body>
</html>
What I found is - it depends on browser. In Chrome it's possible to place LinkButton inside tags. In Firefox and IE 10 it's not.
The reason why it's not working is simple - it's not allowed by the HTML 5 standard. You just can't embed a link inside a button.
