pdf 변환 다운로드

2017. 2. 10. 18:09

c# .net 프로젝트를 하고 있는데 견적서 화면을 pdf로 다운로드 받고 싶다는 고객의 요청~ㅠ

1. Estimate.aspx (견적서 화면)에 pdf로 출력될 내용을 panel로 감쌈

2. CS에 pdf 다운로드 구현 => NReco.PdfGenerator 사용

3. "형식 'UpdatePanel'의 컨트롤 'ContentPage_페널명'은(는) runat=server 구문과 함께 form 태그 내부에 와야 합니다." 에러 발생 ㅠ

=> c# 코드에 하기의 코드로 해결

        public override void VerifyRenderingInServerForm(System.Web.UI.Control control)
        {
            // Confirms that an HtmlForm control is rendered for the specified ASP.NET server control at run time.
        }
