问题描述
大家好，
我在asp.net页面使用c＃有一个转发器。
我添加了一个export2pdf按钮。
代码：
Hi guys,
I have a repeater in asp.net page using c#.
where i have added a export2pdf button.
code:
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=JobReport.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
Repeater1.DataSource = Department.GetDepartments();
Repeater1.DataBind();
Repeater1.RenderControl(hw);
StringReader sr = new StringReader(sw.ToString());
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.Close();
Response.Write(pdfDoc);
Response.End();
代码将转发器数据导出到pdf但没有桌边框和颜色。
i希望导出，因为它转发器，pdf，意思是：颜色，图像，边框......等等，我在转发器中有什么，我想导出它，就像一个图像。 />
任何人都可以帮助我，我该怎么做.......

使用System;
使用System.Web;
使用System.Web.UI;
使用System.Data;
使用System.IO;
使用iTextSharp.text;
使用iTextSharp.text.pdf;
使用iTextSharp.text。 html.simpleparser;
之后写下面的co de in code
protected void Page_Load（object sender，EventArgs e）
{
if（！ IsPostBack）
{
BindGridview（）;
}
}
protected void BindGridview（）
{
DataTable dt = new DataTable（）;
dt.Columns.Add（UserId，typeof（Int32） ））;
dt.Columns.Add（UserName，typeof（string））;
dt.Columns.Add（Education，typeof（string）） ;
dt.Columns.Add（Location，typeof（string））;
DataRow dtrow = dt.NewRow（）; //创建新行
dtrow [UserId] = 1; //将数据绑定到列
dtrow [UserName] =SureshDasari;
dtrow [Education] =B.Tech;
dtrow [Location] =Chennai;
dt.Rows.Add（dtrow）;
dtrow = dt.NewRow（）; //创建新行
dtrow [UserId] = 2; //将数据绑定到列
dtrow [UserName] =MadhavSai;
dtrow [Education] =MBA;
dtrow [Location] =Nagpur;
dt.Rows.Add（dtrow）;
dtrow = dt.NewRow（）; //创建新行
dtrow [UserId] = 3; //将数据绑定到列
dtrow [UserName] =MaheshDasari;
dtrow [Education] =B.Tech;
dtrow [Location] =Nuzividu;
dt.Rows.Add（dtrow）;
gvDetails.DataSource = dt;
gvDetails.DataBind（）;
}
public override void VerifyRenderingInServerForm（Control control）
{
/ *验证控件是否呈现* /
}
protected void btnPDF_Click（object sender，EventArgs e）
{
Response.ContentType =application / pdf;
Response.AddHeader（content-disposition，attachment; filename = UserDetails.pdf）;
Response.Cache.SetCacheability（HttpCacheability.NoCache）;
StringWriter sw = new StringWriter（）;
HtmlTextWriter hw = new HtmlTextWriter（sw）;
this.Page.RenderControl（hw）;
StringReader sr = new StringReader（sw.ToString（））;
文件pdfDoc =新文件（PageSize .A4,10f，10f，100f， 0.0f）;
HTMLWorker htmlparser = new HTMLWorker（pdfDoc）;
PdfWriter.GetInstance（pdfDoc，Response.OutputStream）;
pdfDoc。打开（）;
htmlparser.Parse（sr）;
pdfDoc.Close（）;
Response.Write（pdfDoc）;
Response.End（）;
}
using System;
using System.Web;
using System.Web.UI;
using System.Data;
using System.IO;
using iTextSharp.text;
using iTextSharp.text.pdf;
using iTextSharp.text.html.simpleparser;
After that write the following code in code behind
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindGridview();
}
}
protected void BindGridview()
{
DataTable dt = new DataTable();
dt.Columns.Add("UserId", typeof(Int32));
dt.Columns.Add("UserName", typeof(string));
dt.Columns.Add("Education", typeof(string));
dt.Columns.Add("Location", typeof(string));
DataRow dtrow = dt.NewRow(); // Create New Row
dtrow["UserId"] = 1; //Bind Data to Columns
dtrow["UserName"] = "SureshDasari";
dtrow["Education"] = "B.Tech";
dtrow["Location"] = "Chennai";
dt.Rows.Add(dtrow);
dtrow = dt.NewRow(); // Create New Row
dtrow["UserId"] = 2; //Bind Data to Columns
dtrow["UserName"] = "MadhavSai";
dtrow["Education"] = "MBA";
dtrow["Location"] = "Nagpur";
dt.Rows.Add(dtrow);
dtrow = dt.NewRow(); // Create New Row
dtrow["UserId"] = 3; //Bind Data to Columns
dtrow["UserName"] = "MaheshDasari";
dtrow["Education"] = "B.Tech";
dtrow["Location"] = "Nuzividu";
dt.Rows.Add(dtrow);
gvDetails.DataSource = dt;
gvDetails.DataBind();
}
public override void VerifyRenderingInServerForm(Control control)
{
/* Verifies that the control is rendered */
}
protected void btnPDF_Click(object sender, EventArgs e)
{
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=UserDetails.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
this.Page.RenderControl(hw);
StringReader sr = new StringReader(sw.ToString());
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 100f, 0.0f);
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.Close();
Response.Write(pdfDoc);
Response.End();
}
Response.Clear();
Response.Charset = "";
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.ContentType = "application/vnd.xls";
Response.AddHeader("content-disposition", "attachment;filename=" + "Report.xls");
System.IO.StringWriter sw = new System.IO.StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
((Repeater)Cache["Report"]).RenderControl(htw);
System.Text.StringBuilder sb1 = new System.Text.StringBuilder();

Response.End();
