[Mono-bugs] ImageButton Command event always raised

Fri Sep 30 05:56:50 EDT 2005

Strange behaviour with ImageButton class ! The Command event is raised 
whatever the action in the form ...

Exemple :

<%@ Page Language="C#" AutoEventWireup="True" %>

<html>
<head>
<script language="C#" runat="server">
    static int count = 0;

    protected void Page_Load(object sender, EventArgs e)
    {
        Console.WriteLine("******** {0} ********", ++count);
        Message.Text = "";
    }

    protected void SubmitBtn1_Command(object sender, CommandEventArgs e)
    {
        Console.WriteLine("-- {0} : {1} --", ((WebControl) sender).ID, 
e.CommandName);
        Console.WriteLine("1...");
        Message.Text += "1 !! ";
    }

    protected void SubmitBtn2_Command(object sender, CommandEventArgs e)
    {
        Console.WriteLine("-- {0} : {1} --", ((WebControl) sender).ID, 
e.CommandName);
        Console.WriteLine("2...");
        Message.Text += "2 !! ";
    }

    protected void DDList1_IndexChanged(object sender, EventArgs e) {
        Console.WriteLine("-- {0} --", ((WebControl) sender).ID);
        Console.WriteLine("{0}...", ((DropDownList) sender).SelectedValue);
        Message.Text += String.Format("{0} !! ", ((DropDownList) 
sender).SelectedValue);
    }

    protected void SubmitBtn6_Command(object sender, CommandEventArgs e)
    {
        Console.WriteLine("-- {0} : {1} --", ((WebControl) sender).ID, 
e.CommandName);
        Console.WriteLine("6...");
        Message.Text += "6 !! ";
    }
</script>
</head>
<body>
   <form runat="server" method="get">
