Hello mks-ydi,

I couldn't reproduce your problem using your code. Please, can you explain step to step how we can reproduce your problem here? On the other hand, I am very grateful if you can try to do a test using last version of TeeChart.Net. You can use the evaluation version and try check if your problem persist.

Thanks,

Hello mks-ydi,

I have done many test with your project, and finally I can reproduce your problem. The problem is caused in MasterPage and you can solve it, removing div tab, that doesn't allow zoom works fine, as do in next code:

Code: Select all

<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"
    CodeBehind="Default.aspx.cs" Inherits="ChartZoom._Default" %>

<%@ Register Assembly="TeeChart" Namespace="Steema.TeeChart.Web" TagPrefix="tchart" %>

<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
<style type="text/css">
    .TeeChart
    {
        position:absolute;
        left:200px;
        top:200px;
    }
</style>
</asp:Content>
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
        <tchart:WebChart ID="WebChart1" runat="server" GetChartFile="GetChart.aspx" 
            TempChart="Session" AutoPostback="False" Height="300px" 
            Width="400px"/>
</asp:Content>

And modifying the position of chart into the master page, for example, as do in next lines of code:

Code: Select all

  WebChart1.Style["position"] = "absolute";
            WebChart1.Style["left"] = "200px";
            WebChart1.Style["top"] = "200px";

Can you please, tell us if previous code works as you expected? On the other hand, I inform you, that the build 4.1.2011.4197, you use to check if problem appears, is not the last build of TeeChart.Net, so the last is Build 4.1.2011.06283. I would be very grateful, if you also can make the test in last version of TeeChart.

I hope will helps.

Thanks,
