I have a main page and two web pages, WebForm1 and WebForm2. There are two LinkButtons on the main page to go to WebForm1 or WebForm2.
When I click LinkButton to go to WebForm1, the Page_Load event handler for WebForm1 and Page.IsPostBack == false are called. So far so good.
Then, when I click to go to WebForm2, this happens:
a) The Page_Load event handler for WebForm1 is called again and Page.IsPostBack == true.
b) Then the Page_Load event handler for WebForm2 is called and its Page_Load == false.
Vice versa when going back to WebForm1.
Why is Page_Load called for WebForm1 when I go to WebForm2? I am loading WebForm2, not WebForm1.
For all pages: AutoEventWireup = "true".
<form id="form1" runat="server">
<div>
<p>This is MySite.Master.</p>
<p>
<asp:LinkButton ID="goto1" runat="server" OnClick="goto1_Click">Go To WebForm1</asp:LinkButton>
</p>
<p>
<asp:LinkButton ID="goto2" runat="server" OnClick="goto2_Click">Go To 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) {
}
}
}
