Introduction
Here I am going to demonstrate “how to print particular portion of webpage?”. Manier we use “Window.Print()”
javascript in order to print data displayed on web-page. But there may be a
case when I didn’t need to print whole page or just required to print one small
portion of page instead of whole page, in those scenario “Window.print()” won’t work. So what should we do in such situation?
Here is the answer.
Inside the code
We can print web document through javascript, so definitely
we’ll write some javascript to print portion of web page. Here is the script:
function
CallPrint(strid) {
var
prtContent = document.getElementById(strid);
var
WinPrint = window.open('', '',
'letf=0,top=0,width=1,height=1,toolbar=0,scrollbars=0,status=0');
WinPrint.document.write(prtContent.innerHTML);
WinPrint.document.close();
WinPrint.focus();
WinPrint.print();
WinPrint.close();
prtContent.innerHTML = strOldOne;
}
Now, how to use this javascript? For that create a <div
/> element and assign unique id to it (i.e. <div ID=”divPrint”). Now put
your html content between this <div />.
For example, if I want to print Item information which are
displays on grid like:
<asp:DataGrid Id=”grdItem” runat=”server>
<Columns>
……..
……..
</Columns>
</asp:DataGrid>
Put this whole html content between <div /> tag.
Now onClientClick event of button call javascript function
like:
OnClientClick=”CallPrint(‘divPrint’)”
This
all makes your printing done.
