Add Content-Disposition header with "attachment" value. You can also specify the filename which will be suggested in the Save as dialog:

Response.AddHeader("content-disposition", "attachment;filename=print.png");

Example

    protected void ButtonExport_Click(object sender, EventArgs e)
    {
        setDataSourceAndBind();

        Response.Clear();
        Response.ContentType = "image/png";
        Response.AddHeader("content-disposition", "attachment;filename=print.png");
        MemoryStream img = DayPilotScheduler1.Export(ImageFormat.Png);
        img.WriteTo(Response.OutputStream);
        Response.End();

    }
