using itextsharp.text; using itextsharp.text.pdf; using itextsharp.text.html.simpleparser; using system.io; using system.web.ui.htmlcontrols; my codes:
protected void button1_click(object sender, eventargs e) { using (stringwriter sw = new stringwriter()) { using (htmltextwriter hw = new htmltextwriter(sw)) { //to export pages gridview1.allowpaging = false; gridview1.showheader = true; this.bindgv(); gridview1.rendercontrol(hw); stringreader sr = new stringreader(sw.tostring()); document pdfdoc = new document(pagesize.a2, 10f, 10f, 10f, 0f); htmlworker htmlparser = new htmlworker(pdfdoc); pdfwriter.getinstance(pdfdoc, response.outputstream); pdfdoc.open(); htmlparser.parse(sr); pdfdoc.close(); response.contenttype = "application/pdf"; response.addheader("content-disposition", "attachment;filename=gridviewexport.pdf"); response.cache.setcacheability(httpcacheability.nocache); response.write(pdfdoc); response.end(); } }
this working me using itextsharp 5.5.3
response.clear(); response.clearcontent(); response.clearheaders(); response.charset = string.empty; response.contenttype = "application/pdf"; response.addheader("content-disposition", "attachment;filename=gridviewexport.pdf"); response.cache.setcacheability(httpcacheability.nocache); page.response.buffer = false; using (stringwriter sw = new stringwriter()) { using (htmltextwriter hw = new htmltextwriter(sw)) { gridview1.allowpaging = false; gridview1.showheader = true; this.bindgv(); gridview1.rendercontrol(hw); using (stringreader sr = new stringreader(sw.tostring())) { document pdfdoc = new document(pagesize.a2, 10f, 10f, 10f, 0f); htmlworker htmlparser = new htmlworker(pdfdoc); memorystream ms = new memorystream(); pdfwriter.getinstance(pdfdoc, ms); pdfdoc.open(); htmlparser.parse(sr); pdfdoc.close(); byte[] bytes = ms.toarray(); response.addheader("content-length", bytes.length.tostring()); response.binarywrite(bytes); response.close(); } } }
