ScrollPager just freezes everything

[thor]

Hi,

I'm using TeeChart for WPF version 4.1.2012.5103 and was hoping I could use the ScrollPager on my chart.
Everytime I assign a series to the ScrollPager the application freezes.

Even the WPF demo that came with this version of TeeChart freezes and crashes on the ScrollPager demo.

Please fix this...

Hello thor,

I'm using TeeChart for WPF version 4.1.2012.5103 and was hoping I could use the ScrollPager on my chart.
Everytime I assign a series to the ScrollPager the application freezes.

I can not reproduce your problem using last version of TeeCharWPF and next code:

Code: Select all

public MainWindow()
        {
            InitializeComponent();
            InitializeChart();
        }
        Steema.TeeChart.WPF.Tools.ScrollPager scroll;
        private void InitializeChart()
        {
            Steema.TeeChart.WPF.Styles.Line line = new Steema.TeeChart.WPF.Styles.Line(tChart1.Chart);
            scroll = new Steema.TeeChart.WPF.Tools.ScrollPager(tChart1.Chart);
            line.FillSampleValues();
            scroll.Series = line;

        }

Can you please modify previous code because we can reproduce your problem here?

Even the WPF demo that came with this version of TeeChart freezes and crashes on the ScrollPager demo.

It bug still is in bug list report with number[TW16016189]. We will try to fix it for next maintenance releases of TeeChartFor.Net.

Thanks,

So the problem must be with my setup?

I ran your example and it freezes as well.

If I remove "scroll.Series = line;" everything runs fine.

My environment is :
Win7 Ultimate 64bit. (6.1.7601 SP 1 build 7601)
VS2010 10.0.40219.1 SP1Rel

Please advice on some way to get this working or if you need further details about my environment.

thanks

Hello Thor,

I am afraid I can not reproduce your problem using my previous code and compiled it in X64 machine here.

Can you tell us if you compiled with x86 TeeChart.WPF.dll or x64 TeeChart.WPF.dll? On the other hand,Does appear in your application any exception, caused to the ScrollPager? If the answer is yes, please tell me the exactly exception appears.

Thanks,

[thor]

Hi,

This is compiled with x86.

When I add the scroll pager I don't get an exception it just hangs without drawing the chart.
Breaking with intellitrace gives me the following stacktrace:

It seems it's just hanging on some thread or monitor.

thanks

btw this is after updating to 4.1.2012.7133

Hi thor,

Thanks for the info. I could reproduce the issue here and added it (TW16016276) to the defect list to be fixed.

Hi thor,

After investigating the issue here we found that the problem is when chart dimensions have not been set. ScrollPager tool needs that so you can either declare your chart like this:

Code: Select all

    <my:TChart Margin="0,0,0,0" Name="tChart1"  Height="300" Width="300"/>

Or define dimensions at run-time:

Code: Select all

      tChart1.Width = 300;
      tChart1.Height = 300;

      Steema.TeeChart.WPF.Styles.Line line = new Steema.TeeChart.WPF.Styles.Line(tChart1.Chart);
      line.FillSampleValues();
      Steema.TeeChart.WPF.Tools.ScrollPager scroll = new Steema.TeeChart.WPF.Tools.ScrollPager(tChart1.Chart);
      scroll.Series = line;
