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
