saveAsPNG() with asmx

[toqueheadParticipant]

Can you please provide an example of an asmx implementation of the server method required by jqxChart(‘saveAsPNG’).

The only thing I can find points me at the php example that ships with your pro version. That example is old: it is looking for POST variables format, filename, and content, when jqxChart is actually POSTing fname and content.

But I need asmx anyway.

Thanks.

I managed to answer my own question. The stripped down asmx method is:

public void DownloadContent(string fname, string content)
{
    var response = Context.Response;
    response.Clear();
    response.Charset = "UTF-8";
    response.ContentType = "application/octet-stream";
    response.AppendHeader("Content-Disposition", "attachment; filename=" + fname);
    byte[] bytes = Convert.FromBase64String(content);
    response.OutputStream.Write(bytes, 0, bytes.Length);
    response.Flush();
}
