Good Day,

A few days ago we upgraded our version of IntersoftWebStudio with all updates.
Because of this update however, the OnClientClick Javascript Event for ImageButton does not work anymore.

If you use "<asp:Image>" with OnClick instead of "<asp:ImageButton>" with OnClientClick, it works.
This problem seems to only occur with ImageButtons.

I've uploaded a testsite for you to look at as an attachment + I added the code in this post as well.

The Intersoft Version we are using:


The ASPX Page:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="TestImageButton.aspx.cs"
    Inherits="Test_Debug_TestImageButton" %>

<%@ Register Assembly="ISNet.WebUI.WebDesktop" Namespace="ISNet.WebUI.WebDesktop"
    TagPrefix="ISWebDesktop" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
<html>
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <ISWebDesktop:WebFlyPostBackManager ID="uiService" runat="server" ServiceUrl="TestImageButton.aspx"
        TimeoutInterval="900" LoaderStyle-BackColor="Black" BlockPageUIOnBusy="true"
        EnableUIMode="true">
        <FlyPostBackSettings PostControlState="true" PostHiddenFields="true" PostInputControls="true"
            PostViewState="true" />
    </ISWebDesktop:WebFlyPostBackManager>
    <asp:ImageButton ID="ImageButton" runat="server" OnClientClick="alert('Javascript is working!');"
        AlternateText="ClickMe" />
    </form>
</body>
</html>

The ASPX.cs Page:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using ISNet.WebUI;
using ISNet.WebUI.WebDesktop;

public partial class Test_Debug_TestImageButton : System.Web.UI.Page
{
    WebFlyPostBackListener listener = null;

    protected void Page_Load(object sender, EventArgs e)
    {

        listener = new WebFlyPostBackListener(this);
    }
}

regards,

Wolfgang Pichler
