Hi Jackey,

Zoom can not be done using TeeChart for .NET in WebForms. However a DrillDown operation could be done.

For zooming you could use TeeChart Pro ActiveX (a free version is included with each TeeChart for .NET license) as the component is inserted in the WebForm as an object, while TeeChart for .NET component is an image in an ASP.NET page.

Hi,narcis,
Thanks for your replay.
If I use TeeChart Pro ActiveX, do you dnow whether I can use ADO.NET as DataSource? According to the Tutorials, user only use ADO as DataSorce.

Hi Jackey,

No, ADO.NET can't be used as a datasource using TeeChart Pro ActiveX in .NET WebForms, you should have to do loop through the datasource and then use AddXY for example.
