c# - Page_Load is called when leaving page -

i have master page , 2 web pages, webform1 , webform2. on master page there 2 linkbuttons in order go webform1 or webform2.

when click on linkbutton go webform1 page_load event handler webform1 called , page.ispostback == false. far good.

then when click go webform2 happens:

a) page_load event handler webform1 called again , page.ispostback == true. b) page_load event handler webform2 called , page_load == false.  vice versa when going webform1. 

why page_load webform1 called when i'm going webform2? loading webform2 , not webform1.

for pages: autoeventwireup="true".

<form id="form1" runat="server"> <div>     <p>this mysite.master.</p>     <p>         <asp:linkbutton id="goto1" runat="server" onclick="goto1_click">go webform1</asp:linkbutton>     </p>     <p>         <asp:linkbutton id="goto2" runat="server" onclick="goto2_click">go webform2</asp:linkbutton>     </p>      <asp:contentplaceholder id="contentplaceholder1" runat="server">     </asp:contentplaceholder> </div> </form>   protected void goto1_click(object sender, eventargs e) {     response.redirect("webform1.aspx"); }  protected void goto2_click(object sender, eventargs e) {     response.redirect("webform2.aspx"); }    public partial class webform1 : system.web.ui.page {     protected void page_load(object sender, eventargs e) {          if (page.ispostback) {          }     } }    public partial class webform2 : system.web.ui.page {     protected void page_load(object sender, eventargs e) {          if (page.ispostback) {          }     } } 

to add on kirk's answer...

when want simple link page, don't use linkbutton @ all. linkbutton submit button, designed link - it's hooked magically through javascript asp.net builds automatically.

if want link send page, in regular html:

<a href="webform2.aspx">go webform2</a>
