Export throws IndexOutOfRangeException

[Oops]

I am trying to implement a functionality wherein if the user clicks on a chart in the webpage, a new webpage opens up with an expanded version of the chart.

Now my code looks like this

 MemoryStream mm = new MemoryStream(); ((Chart)PreviousPage.FindControl("Chart1")).Export(mm); Chart2.Import(mm ); But when i run this i get a exception like so :

System.IndexOutOfRangeException was unhandled by user code  Message="Index was outside the bounds of the array."  Source="ChartFX.WebForms"

 at the 3rd line where i do the import. Can anyone help in pointing out what might be wrong here.

Thanks.

After export, the position in the stream is at the end of it, that's the reason Import fails.

you need to do:

mm.Position = 0;
