HI all,

I have a weird problem in my page. I have a button called Print. I wanted report should come in a new tab, so i wrote some javascript on button's onClientClick. Which works great with no problem at all.

But problem starts now when user comes back on original page again, now here i have several controls which cause postback. Say for example its a dropdownlist. so whenever user changes dropdown item it causes postback which is fine but everytime it opens a new tab on every postback.

hope I am clear in question...

Any help??

Here is a code:

ASP.NET

<asp:button ID="btnPrint" runat="server" Text = "Print" OnClick="btnPrint_Click" onClientClick="aspnetForm.target='_blank'" />

Hi,

On page load event check IsPostBack and load you settings according to that.

that is not really possible because to open a new tab on button click is written on onClientClick so before i get on page load event it has already opened a new tab.

first of all thanks Hiren, i had a same problem as like you but using your solution i sort it out

in aspx;
inside body section
write the following

C#

<body onload="fixform()">

then write a javascript

C#

<script type="text/javascript">
    function fixform() 
    {
        document.getElementById("Form1").target = '';       
    }

remember you have set target ='_blank' onClientClick
for viz.:

C#

<asp:button id="btnPrint" runat="server" text="Print" onclick="btnPrint_Click" onclientclick="Form1.target='_blank'" xmlns:asp="#unknown" />
