Hi,

We get a System.IndexOutOfRangeException when we want to show a hidden highLow serie. The Teechart is used in a ASP.net 2003 application.
The chart is created with the highLow series hidden. Then we cache the chart so we have it after a postback.

In the event of a checkbox we switch the serie on or off. (value checkbox).

When we do this in code by generate the chart there is no problem (we can hide and show, but when we do this in like so :

Code: Select all

// something goes here wrong !!! indexout of bound exeption
private void minMaxValue_CheckedChanged(object sender, System.EventArgs e)
        {
            try
            {
            
                bool minMaxChecked =  minMaxValue.Checked;
        
                foreach(DictionaryEntry lineDescEntry in WebChartSerieLineDesc)
                {
                    string lineDesc = lineDescEntry.Value.ToString().ToLower();
                    int serieNr = int.Parse(lineDescEntry.Key.ToString());

                    if ((lineDesc  == "min") || (lineDesc== "max"))
                    {
                        if(GraphDetail.Chart.Series[serieNr].Visible != minMaxChecked)
                        {   
                            GraphDetail.Chart.Series[serieNr].Visible  = minMaxChecked;
                    
                        }
                    }
                    else
                    {
                        if(lineDesc == "min/max")
                        {
                           // HighLow series
                           Steema.TeeChart.Styles.HighLow highLowStyle = (Steema.TeeChart.Styles.HighLow)GraphDetail.Chart.Series[serieNr];
                           highLowStyle.Visible =   minMaxChecked; 
                        }
                    }
                }
            }
            catch (Exception error)
            {
                HDBPageHeaderSubPlus.ErrorMessage = error.Message;
                General.Log.Write(error,"minMaxValue_CheckedChanged",pageName);
            }
        }
    }

It thows the following exception after exiting the event.

Global.asax.Application_Error: Error: System.Web.HttpUnhandledException: Er is een uitzondering van het type System.Web.HttpUnhandledException veroorzaakt. ---> System.IndexOutOfRangeException: De index ligt buiten de matrixgrenzen.

Hi Roland,

Thank you very much for the example. It works fine for me here using TeeChart for .NET v2 latest Debug build available at our Customer Download Area. Which TeeChart version are you using?

I enabled and disabled all checkboxes in the WebForm. Are there any special steps I should follow to reproduce the problem?

Thanks in advance.

Sorry for not having noticed before. We have been able to reproduce the problem and fixed it for the next TeeChart for .NET v1 maintenance release.

Yes, you won't have any problem upgrading from v1 to v2. You can do it on-line here. For further information please contact our Sales Dept. at sales@steema.com.
