Printing an ASP.NET Web Site page

asp.net

Solution

If you want to print only a Datalist from a webpage. You can create a Div Name around the datalist and use the below code

<script language="javascript">
    function printDiv(divName) {
        var printContents = document.getElementById(divName).innerHTML;
        var originalContents = document.body.innerHTML;

        document.body.innerHTML = printContents;

        window.print();

        document.body.innerHTML = originalContents;
    }
</script>

Give a div name around the Datalist like this.

<div id="PrintDiv">
       <asp:DataList ID="DataList1" runat="server">     </asp:DataList>
</div>

Finally Create a print button.

<input type="button" onclick="printDiv('PrintDiv')" value="Print only Datalist!" />

EDIT

Your exact code worked for me. I created a ASP.NET website (Not Project). I copied your entire code and pasted into a new page and it worked.

The only thing I changed is the following.

I changed `CodeBehind="PageLinkDetails.aspx.cs"` to `CodeFile="PageLinkDetails.aspx.cs"`

<%@ Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true"
 CodeFile="PageLinkDetails.aspx.cs" Inherits="TestDataBase.PageLinkDetails" %>

EDIT

Here is my Complete Code.
