How to Print a Asp.net Gridview.

You want to print only Gridview not entire page.

Solution is, put Gridview inside a Panel as below:

<asp: Panel runat="server" id="pnlToPrint" >
 <asp:GridView ID="gvReport" runat="server"........>
 ............
 ..............
 ............
 </asp:GridView>
</asp: Panel>
 <input type="button" value="Print"  onclick="CallPrint();" />

Now create a function as below:

function CallPrint()
{
  var printContent = document.getElementById('<%= pnlToPrint.ClientID %>');
  var printWindow = window.open("", "Print Panel", 'left=50000,top=50000,width=0,height=0');
  printWindow.document.write(prtContent.innerHTML);
  printWindow.document.close();
  printWindow.focus();
  printWindow.print();
  printWindow.close();
}
