how to Encript and decript values

how to export gridview data to PDF using asp.net or Export gridview data to PDF using asp.net

Introduction:

Here I will explain how to export gridview data to PDF using asp.net.

Description:

In my previous articles I explained clearly how to export gridview data to excel or word and how to export gridview data to CSV file . Now I will explain how to export gridview data to PDF using asp.net. In asp.net we don’t have direct feature to export gridview data to PDF for that reason here I am using third party library ITextSharp reference. The dll is available here ITextSharp first download dll from this site after that create one new website in visual studio and add ITextsharp dll reference to newly created website after that design aspx page like this 

 <html xmlns="http://www.w3.org/1999/xhtml">

<head id="Head1" runat="server">

<title></title>

</head>

<body>

<form id="form1" runat="server">

<div>

<table>

<tr>

<td align="right">

<asp:ImageButton ID="btnPDF" runat="server" ImageUrl="~/PDF.jpg" Width="32px"

Height="32px" onclick="btnPDF_Click"/>

</td>

</tr>

<tr>

<td>

<asp:GridView runat="server" ID="gvdetails" DataSourceID="dsdetails"  AllowPaging="true" AllowSorting="true" AutoGenerateColumns="false">

<RowStyle BackColor="#EFF3FB" />

<FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />

<PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" />

<HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />

<AlternatingRowStyle BackColor="White" />

<Columns>

<asp:BoundField DataField="UserId" HeaderText="UserId" />

<asp:BoundField DataField="UserName" HeaderText="UserName" />

<asp:BoundField DataField="LastName" HeaderText="LastName" />

<asp:BoundField DataField="Location" HeaderText="Location" />

</Columns>

</asp:GridView>

</td>

</tr>

</table>

<asp:SqlDataSource ID="dsdetails" runat="server" ConnectionString="<%$ConnectionStrings:dbconnection %>"

SelectCommand="select * from UserInformation"/>

</div>

</form>

</body>

</html>

<connectionStrings>

<add name="dbconnection" connectionString="Data Source=SureshDasari;Integrated Security=true;Initial Catalog=MySampleDB"/>

</connectionStrings>

 

Now in code behind add these references

using iTextSharp.text;

using iTextSharp.text.pdf;

using iTextSharp.text.html.simpleparser;

After that write the following code in code behind

public override void VerifyRenderingInServerForm(Control control)

{

/* Verifies that the control is rendered */

}

protected void btnPDF_Click(object sender, ImageClickEventArgs 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);

gvdetails.AllowPaging = false;

gvdetails.DataBind();

gvdetails.RenderControl(hw);

gvdetails.HeaderRow.Style.Add("width", "15%");

gvdetails.HeaderRow.Style.Add("font-size", "10px");

gvdetails.Style.Add("text-decoration", "none");

gvdetails.Style.Add("font-family", "Arial, Helvetica, sans-serif;");

gvdetails.Style.Add("font-size", "8px");

StringReader sr = new StringReader(sw.ToString());

Document pdfDoc = new Document(PageSize.A2, 7f, 7f, 7f, 0f);

HTMLWorker htmlparser = new HTMLWorker(pdfDoc);

PdfWriter.GetInstance(pdfDoc, Response.OutputStream);

pdfDoc.Open();

htmlparser.Parse(sr);

pdfDoc.Close();

Response.Write(pdfDoc);

Response.End();

}

  If you observe above code I added one function that is VerifyRenderingInServerForm this function is used to avoid the error like “control must be placed in inside of form tag”. If we set VerifyRenderingInServerForm function then compiler will think that controls rendered before exporting and our functionality will work perfectly
