I am trying to call a print function to print a string from a database using javascript.
Which is RC_DATA of Varchar2(2500).
This is a javascript is not being used. I have a thing that needs to be modified:
if(e.CommandName =="Print")
{
string parsedreceipt = null;
parsedreceipt = DecodeReceipt (e.Item.Cells[3].Text);
Session["parsedreceipt"] = parsedreceipt;
/// Response.Write("<script language=\"JavaScript\">window.OpenNewWin('print.aspx', null, 'height=200,width=400');");
Response.Write("<script language=\"JavaScript\">window.open('print.aspx', null, 'height=200,width=400');</script>");
}
I am confused on what to do? I just want to print the string.
<script language="javascript">
function OpenNewWin(Receipt)
{
winNew = window.open("print.aspx?","printwindow","toolbar=no,scrollbar=no,height=200,width=300,resizable=no,top=200,left=200");
var PrintHtml ="<Table cellpadding=5 cellspacing=5 broder=0>";
PrintHtml = PrintHtml + "<TR><TD>Receipt</TD><TD width=5>:</TD><TD>" + Receipt + "</TD></TR>";
PrintHtml = PrintHtml + " </TABLE>";
PrintHtml = PrintHtml + " <DIV id=butPanel align=center> <input Type=button value=' Print ' onclick=Javascript:document.getElementById('butPanel').style.display='none';window.print();document.getElementById('butPanel').style.display='';>";
PrintHtml = PrintHtml + " <input type=button value=cancel onclick=javascript:window.close();></Div>";
winNew.document.body.innerHTML=PrintHtml;
winNew.focus();
}
</script>
