Hello,

I am trying to open a popup window on click of a button.I have tried the following code but it is not working:

Button btn = Page.FindControl("btndefer") as Button;
btn.Attributes.Add("onClick","javascript:window.open('DeferReason.aspx','width=500,height=245,left=350,top=400')");

Have also tried:

btndefer.Attributes.Add("onClick", "window.open('DeferReason.aspx'); return false;");

Also tried

string popupScript = "<script language='javascript'>" +
     "window.open('DeferReason.aspx ',  " +
     "'width=200, height=200, menubar=no, scrollbars=yes')" +
     "</script>";
      Page.RegisterStartupScript("PopupScript", popupScript);

How to make it working?

Bye

Any error? check in firefox error console. If yes then include that in your question & let me know.
Also ensure if your popup blocker not blocked that popup window.

Try this

XML

<%@ Page Language="C#" %>
<%@ Import namespace="System.Text" %>
<script runat="server">
    void Page_load(object sender, EventArgs e)
    {
       Button1.Attributes.Add( "onclick", "popWin();return false;" ); 
     }
</script>
<html>
<head>
  <script>
   function popWin(){
        window.open('http://msdn.microsoft.com', '', '');");
   }
   </script>
    </head>
<body>
    <form runat="server">
        <asp:Button id="Button1" onclick="Button1_Click" runat="server" Text="Go!"></asp:Button>
    </form>
</body>
</html>

If ur using button then u can use OnClientClick like

C++

<asp:Button ID="Button1" OnClientClick="return testing();" runat="server" Text="Button" />

in javascript write like

C#

function testing()
   {
    window.open("Default2.aspx");
    return false;
   }

The Error in your code is that

C#

Button btn = Page.FindControl("btndefer") as Button;
btn.Attributes.Add("onClick","javascript:window.open('DeferReason.aspx','width=500,height=245,left=350,top=400')");

when you write this code what .net does is this in html

<input type="submit"  önclick="javascript:window.open(" deferreason.aspx="," width="500,height=245,left=350,top=400')'" value="Error Code"></input>

So in the above you see that the before the onClick .net puts single Quotes and you have put single Quotes in the code as well so it the quotes is the problem

So try this

C#

Button btn = Page.FindControl("btndefer") as Button;
btn.Attributes.Add("onClick","javascript:window.open(\'DeferReason.aspx\',\'_blank\',\'width=500,height=245,left=350,top=400\')");

See this revised code
