Binding OWC Chart to a DataSet? article 303016

[rockdale]

Hi, all

After trial and fail, I realized that you can not binding a
ChartSpace.DataSource to a DataSet of ADO.net. I am using ASP.net 2.0
and OWC11.

From the article 303016

http://support.microsoft.com/default.aspx?scid=kb;en-us;303016. We need
to transform a dataset to a xml.

But with my website has more than 100 chart, do I need to create 100
different MakeData.aspx files? How can I put these 100 different aspx
files into my web. the xslt files I guess I can make the dataset
consistant with the fields.

Or should I just use literal data, loop through the dataset
(datareader), then get 3 arrays (serial, category and values) back,
(seems kind stupid since data is there, and I need to add every field
into a different array without duplicate entries).

Any better idea?

Thanks a lot

Yup, because the ado.net dataset does not implement ilistsource interface.
However, it's pretty trivial to work your way around that. I posted a rough
idea of the code that you can use in another thread a short while ago.
