Steps to create Master Page:
- Right-click your web project in the Solution Explorer window
- Select Add New Item.
- Select the Master Page item type from the Add New Item dialog.
Following is an example of Master Page and a Content Page.
<%@ Master %>
<html>
<body>
<Title>Title of the Pages</Title>
<asp:ContentPlaceHolder id="Content1" runat="server">
</asp:ContentPlaceHolder>
</body>
</html>
- This is simple HTML page that serves template for other pages.
- The @ Master directive at the top of the page defines that the page is Master Page.
- A placeholder tag <asp:ContentPlaceHolder> is overridden by the content page to place the content.
- You can have many placeholders tag each of them with different id.
Content Page Example
%@ Page MasterPageFile="master1.master" %>
<asp:Content ContentPlaceHolderId="Content1" runat="server">
<h1>ASP Interview Questions</h1>
</asp:Content>
When you request this page, ASP.NET merges layout specified in the Master Page and content of content page to produce page result.
