Hi durensky,

hi, I have the problem, when I set a project with ajax.net, and use the example code in it ,there is a error in this code:

zoomedState = ((Steema.TeeChart.Tools.ZoomTool)wChart.Chart.Tools[0]).SetCurrentZoom(Request,
zoomedState);

the error information is:Parameter is not valid

Can you please send us a simple example project we can run "as-is" to reproduce the problem here? You can either post your files at news://www.steema.net/steema.public.attachments newsgroup or at our upload page.

so ,please answer me , can v3 surpport ajax.net?

TeeChart for .NET v3 supports AJAX and can be used in an UpdatePanel to limit any repaints to that page zone alone. TeeChart also offers some specific optimisations using AJAX clientside code to permit scrolling without a return trip to the server and to capture Chart zoom requests.
There are some live examples of that included with the ASP.NET demo portion of the evaluation version if you'd like a closer look. You can also find the live ASP.NET demo here.

zoomedState);

Hi durensky,

How are you using WebChart in an Ajax page? Are you using it in an UpdatePanel?

Thanks in advance.

Hello,

Please send in an example project that reproduces the problem to help us visualise it (to the link in Narcís's previous post). Creating a new project here with Ajax extensions ('Web site with ASP.NET 2.0 AJAX Extensions 1.0 features enabled (.NET Framework 3.5)') doesn't reproduce the problem. Perhaps we're missing some aspect of the setup.

Regards,
Marc Meumann
