my asp:LinkButton does not perform its OnClick action when I add a second button

Question

I am having to have 2 buttons to correctly behave inside a div.

If I set a single button redirecting to a code behing method, it works fine:

<div class="divBtNavCommande">
     <asp:LinkButton ID="bt_1" runat="server" OnClick="myAction">
      My text 1
     </asp:LinkButton>                  
</div>

If I add a second buttons redirecting to a link, the redirection works fine but the first button nolonger performs the code behind action:

 <div class="divBtNavCommande">
     <asp:LinkButton ID="bt_1" runat="server" OnClick="myAction">
       My text 1
     </asp:LinkButton>

     <asp:LinkButton ID="bt_2" runat="server" PostBackUrl="~/MyPage.aspx">
       My text 2
     </asp:LinkButton>
</div>

And if I remove the PostBackUrl="~/myPage.aspx"part, the first button works again.

What is wrong?

Is it a typo or have you forgot to add a `OnClick` method on the second linkbutton? — Hypnobrew, Nov 03 '16 at 13:35
@ElectricRouge : was a typo in my question, I updated the post. — A.D., Nov 03 '16 at 13:42
@Hypnobrew : the second button performs a PostBackUrl="~/MyPage.aspx" — A.D., Nov 03 '16 at 13:43
For me you code seems to be correct, Try clean and rebuld the solution — Jaydip Jadhav, Nov 03 '16 at 13:48
@ Hypnobrew : yep. Button1 should perform a code behind action. Button 2 should perform a redirect. — A.D., Nov 03 '16 at 13:50
Ok, I see now after you fixed the code. Maybe you can try to set the `PostBackUrl` on bt_1 explicit? — Hypnobrew, Nov 03 '16 at 13:52
@ JP Hellemons : I used a LinkButton as well so I could keep the same class / design for both buttons — A.D., Nov 03 '16 at 13:56
@A.D. and are both buttons on `MyPage.aspx`? because a "form" submit is a postback, so you do not need the `PostBackUrl` attribute if they are on the `MyPage.aspx` webform. — JP Hellemons, Nov 03 '16 at 14:01
@JP Hellemons : no these 2 buttons are on a different page than MyPage.aspx. — A.D., Nov 03 '16 at 14:07

YourPage.aspx:

<div class="divBtNavCommande">
 <asp:LinkButton ID="bt_1" runat="server" OnClick="myAction">
   My text 1
 </asp:LinkButton>

 <asp:LinkButton ID="bt_2" runat="server" OnClick="bt_2_OnClick">
   My text 2
 </asp:LinkButton>
</div>

YourPage.aspx.cs:

protected void bt_2_OnClick(object sender, EventArgs e)
{
    Response.Redirect("MyPage.aspx");
}

Because you said that it was for nagivation purposes only. Otherwise use Server.Transer(); more info here: https://stackoverflow.com/a/6778952/169714

That would work, this is what I had in mind. Thanks. Do you know why the solution that I posted does not work although both buttons operate correctly separately if I add only one of the 2 buttons (any of the 2), but do not work if the 2 buttons are present? – A.D. Nov 03 '16 at 14:18
Perhaps your `Page_Load` show some more code behind ;) As said here https://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.linkbutton.postbackurl(v=vs.110).aspx perhaps the server-side validation? I need more context I think. – JP Hellemons Nov 03 '16 at 14:23
