You should also inherit from the IPostBackEventHandler interface and implement the RaisePostBackEvent so that it raises your click event.

Venkatesh MookkanHere "Page" throws NullReferenceException. I have already tried it and removed it.

<DefaultProperty("Text"), ToolboxData("<{0}:EglLabel runat=server></{0}:EglLabel>"), _<br />

    Public Class EglLabel<br />

        Implements IPostBackEventHandler<br />

        Public Event Click As EventHandler<br />

        Protected Overridable Sub OnClick(ByVal e As EventArgs)<br />
            RaiseEvent Click(Me, e)<br />
        End Sub<br />
<br />
        Public Sub RaisePostBackEvent(ByVal eventArgument As String) Implements System.Web.UI.IPostBackEventHandler.RaisePostBackEvent<br />
            OnClick(EventArgs.Empty)<br />
        End Sub<br />

        Public Sub New()<br />
            Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(Me, ClientID))<br />
        End Sub<br />
    End Class

Venkatesh MookkanPublic Sub New()
Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(Me, ClientID))
End Sub
End Class
