Question
I want to print the gantt shown on a webpage.
Answer
You will need to perform the rending server side. The general idea is the same as explained in this article https://plexityhide.com/faqs_gen_GTPNET/10374.htm.
To be more precise this is how it is done if you want the result to returned as jpeg:
protected void LinkButton1_Click(object sender, EventArgs e)
{
Bitmap bm = new Bitmap(Gantt_ASP1.Gantt.Width, 300 + Gantt_ASP1.Gantt.DateScalerHeight);
Graphics g = Graphics.FromImage(bm);
Rectangle r = Rectangle.FromLTRB(0, 0, Gantt_ASP1.Gantt.Width, 300 + Gantt_ASP1.Gantt.DateScalerHeight);
g.FillRectangle(Brushes.White, r);
bool hasMorePages = false;
Gantt_ASP1.Gantt.PrintInit(null);
Gantt_ASP1.Gantt.PrintPage(g, r, Gantt_ASP1.Gantt.GridWidth + 10, Gantt_ASP1.Gantt.DateScalerHeight, ref hasMorePages);
Gantt_ASP1.Gantt.PrintEnd();
Response.Clear();
Response.ContentType = “image/jpeg”;
Response.AddHeader(“Content-Disposition”, “attachment; filename=GanttASP.jpeg”);
bm.Save(Response.OutputStream, ImageFormat.Jpeg);
Response.End();
bm.Dispose();
g.Dispose();
}
If you want to to pdf or something like that, the basic principle applies, but you will need an additional tool to render the pdf.
