Error when switching TempChart from Httphander to File

Hi,

I'm having a problem when I switch the TempChart property from HttpHandler to File.

I have a simple time series chart where I've added a number of points at runtime. If I compile my application and run it the chart will appear as expected irrespective of which TempChart setting I use (i.e. File or Httphandler). However if I include the following lines:

Code: Select all

Dim scrollTool As New Steema.TeeChart.Tools.ScrollTool(WebChart1.Chart)
scrollTool.SegmentViewUnits = Steema.TeeChart.Tools.ScrollToolViewUnit.percent
scrollTool.ViewSegmentSize = 10
scrollTool.StartPosition = 10

I get the following error at runtime whenthe TempChart is set to File only:

Length cannot be less than zero.
Parameter name: length
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.ArgumentOutOfRangeException: Length cannot be less than zero.

System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +2558

Everything works as expected when TempChart is set to Httphandler but I wish to use File for another reason.

As I understand it neither rely on GetChart.aspx so that isn't the problem? I've recompiled the application, stopped and started the web publishing service, cleared the history and cleared out the _chart_temp directory between attempts just to make sure I'm starting afresh each time. Could it be an issue with the particular build of TeeChart I'm using?

The release notes indicate:

Hi norman,

I'm not sure if any bug in this field has been fixed. However I strongly recommend you to try using latest version which is build 3.5.3225.32183/4/5 from 3rt November 2008. As you can see in the release notes a lot of issues have been fixed, enhanced and implemented since January.

Thanks in advance.
