Hi, since I'm working with VS 2002, I can't install WEB chart v2. My question is what client side events has been added to the new version of WEB chart.
thanks

Hi Hermes,

Hi, since I'm working with VS 2002, I can't install WEB chart v2.

Yes, that's right. If I'm not wrong, I told you TeeChart for .NET v2 should be compiled with VS.NET 2002 (.NET Framework v1.0 ) to be compatible with it.

My question is what client side events has been added to the new version of WEB chart.

There's one new run-time event for WebChart which is the HotSpots tool. You can view live examples of that at v2 .NET web demo.

Narcís, I'm only want to know, if you can say it to me, if I can drop something on the chart and with JavaScript in the client to know where it was droped, series, axis, background, labels.....

Hi Hermes,

You may code clientside Chart x,y co-ordinates in Javascript to respond to click, mouseover, etc using the hotspot tool and creating an event to handle the processing you want. Alternatively you can pass the co-ordinate back to the server code-behind module to further process it. Examples of both techniques are included in the TeeChart webdemo installed with TeeChart or viewable via http://www.steema.net/TeeChartForNET/index.aspx . I don't have any specific examples of drag-drop, as you have described, in JScript, but the underlying principles using co-ordinates would be the same.

This tecniques are typically used for drill-down, data related navigation or to return additional information to the client.
