Adding OnClick event to an ASP.NET Label control

It's a strange requirement, but I bumped into it when helping out a user on the forums. Here's how to add an OnClick event to the ASP.NET Label Control


 


<html xmlns="http://www.w3.org/1999/xhtml">


<head runat="server">


    <title></title>


    <script type="text/javascript">


        function CallMe() {


            alert('Hi');


        }


    </script>


</head>


<body>


    <form id="form1" runat="server">


    <div>


        <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>


    </div>


    </form>


</body>


</html>




Now in the Code Behind, use the Control.Attributes.Add() to add the OnClick event to the Label Control

C#


    protected void Page_Load(object sender, EventArgs e)


    {


        Label1.Attributes.Add("onClick", "CallMe();");


    }




VB.NET


 


Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)


    Label1.Attributes.Add("onClick", "CallMe();")


End Sub

    Could you please explain how to catch the event? I just get a java error now and adding a sub in VB.net does not work (adding a sub CallMe).
