Load (Display) ASPX page content into another page in ASP.Net

Hi mahesh213,

You have to use the IFrame inside employee.aspx to display country.aspx page

Refer below sample.

HTML

Employee.aspx

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
 <asp:Label ID="Label1" Text="Employee Page" runat="server" /><br />
    <iframe src="Country.aspx"></iframe>
</asp:Content>

Country.aspx

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
    <asp:Label Text="Country Page" runat="server" />
</asp:Content>
