Method 1

You could use Like this:

protected void btnNewEntry_Click(object sender, EventArgs e)

Method 2

Why not just call straight from OnClick?

<asp:Button ID="btnNewEntry" runat="Server" CssClass="button" Text="New Entry" OnClick="'New.aspx')" />

Method 3

Take care to reset target, otherwise all other calls like Response.Redirect will open in a new tab, which might be not what you want.

<asp:LinkButton OnClientClick="openInNewTab();" .../>

In javaScript:
<script type="text/javascript">
    function openInNewTab() {
        window.document.forms[0].target = '_blank'; 
        setTimeout(function () { window.document.forms[0].target = ''; }, 0);

Method 4

Use JavaScript for the main form / Button click event. An example is:

Context.Response.Write("<script language='javascript'>'AccountsStmt.aspx?showledger=" & sledgerGrp & "','_newtab');</script>")

Method 5

Try This

<a href="#" rel="nofollow noreferrer noopener" target="_blank">Link</a>

Method 6

try this rather than redirect…


Method 7

Just had the same problem. Client-side wasn’t appropriate because the button was posting back information from a listview.

Saw same solution as Amaranth’s on way2coding but this didn’t work for me.

However, in the comments, someone posted a similar solution that does work

OnClientClick="document.getElementById('form1').target ='_blank';"

where form1 is the id of your form.

Method 8

You have to use Javascript since code behind is server side only. I am pretty sure that this works.

<asp:Button ID="btnNewEntry" runat="Server" CssClass="button" Text="New Entry" OnClick="btnNewEntry_Click" OnClientClick=" ='_blank';"/>

protected void btnNewEntry_Click(object sender, EventArgs e)

Method 9

Add this Script  
<script type = "text/javascript">
 function SetTarget() {
     document.forms[0].target = "_blank";
<asp:Button ID="BTNpRINT"  runat="server" Text="PRINT"  CssClass="btn btn-primary"  OnClick="BTNpRINT_Click" OnClientClick = "SetTarget();"/>    
protected void BTNpRINT_Click(object sender, EventArgs e)

Method 10

You can add to your button OnClientClick like so:

<asp:Button ID="" runat="Server" Text="" OnClick="btnNewEntry_Click" OnClientClick="target ='_blank';"/>

This will change the current form’s target for all buttons to open in new tab. So to complete the fix you can then use 2 approaches:
  1. For any other button in this form, add to client click a “reset form target” function like so:

function ResetTarget() {
   window.document.forms[0].target = '';
  1. Add the same code inside the function inside a setTimeout() so the code will reset the form’s target after few moments. See this answer

Method 11

Per Open a URL in a new tab (and not a new window) using JavaScript

Nothing an author can do can choose to open in a new tab instead of a new window.

The browser decides between opening a new tab or opening a new window. You cannot control this as a developer.

Method 12

In either on button click or on link button click, this will work.

System.Web.UI.ScriptManager.RegisterClientScriptBlock(Me, Me.GetType(), "openModal", "'CertificatePrintViewAll.aspx' ,'_blank');", True)

Method 13

add target=’_blank’ after check validation :

    <asp:button id="_ButPrint"  ValidationGroup="print" OnClientClick="if (Page_ClientValidate()){$('form').attr('target','_blank');}"  runat="server" onclick="ButPrint_Click" Text="print" />

Method 14

You could do this on the ASPX HTML front end to make the button go to a new tab to show page in your ASP.NET site dynamically:

        <asp:Button ID="btnNewEntry" CssClass="button"  OnClientClick="'https://website','_blank'); return false;" text="WebsiteName"  runat="server" />

Method 15

If the url is dynamic and you want to control it in the code behind

<asp:Button ID="btnNewEntry" runat="Server" Text="New Entry" />

//code behind
var id = 0;
btnNewEntry.OnClientClick = $"'New.aspx?ID={id}')";

Method 16

A simple solution:

<a href="" rel="nofollow noreferrer noopener" target="_blank">
    <button type="button">Open new tab</button>

Method 17

You shuld do it by client side. you can place a html hyperlink with target=”_blank” and style=”display:none”.
after that create a javascript function like following

function openwindow(){
return false;

use this function as onclientclick event handler of the button like onclientclick=”return openwindow()”
You need to include a jquery in the page.

Method 18

Add_ supplier is name of the form

private void add_supplier_Load(object sender, EventArgs e)
    add_supplier childform = new add_supplier();
    childform.MdiParent = this;
