How can I avoid a nested form situation? - asp.net

Ok basically I have a master page which has all the design in a Form with runat server as follows:
<head runat="server">
<title></title>
<asp:ContentPlaceHolder ID="head" runat="server">
</asp:ContentPlaceHolder>
</head>
<body>
<form id="form1" runat="server">
<table style="font-family: Arial">
<tr>
<td colspan="2" style="width: 800px; height: 80px; background-color: #3399FF; text-align: center">
<h1>WebSite Header
</h1>
</td>
</tr>
<tr>
<td style="height: 500px; background-color: #66FFFF; width: 150px">
<h3>Menu</h3>
</td>
<td style="height: 500px; background-color: #9999FF; width: 650px">
<h3>content</h3>
<div>
<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
<p>
</p>
</asp:ContentPlaceHolder>
</div>
</td>
</tr>
<tr>
<td colspan="2" style="background-color: #3399FF; text-align: center">
<b>Website Footer</b>
</td>
</tr>
</table>
</form>
</body>
</html>
Now I am trying to do a page using this master page and in this page I am initializing a CKEditor which apparently needs to be in a form with runat server to be able to function, as follows:
<%# Page Title="" Language="C#" MasterPageFile="~/Site1.Master" AutoEventWireup="true" CodeBehind="CkEditor.aspx.cs" Inherits="WebApplication5.CkEditor" %>
<%# Register Assembly="CKEditor.NET" Namespace="CKEditor.NET" TagPrefix="CKEditor" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
<form id="form2" runat="server">
<div>
<div>
<CKEditor:CKEditorControl ID="CKEditor1" runat="server">
</CKEditor:CKEditorControl>
</div>
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
<asp:Label ID="lblText" runat="server" Text=" "></asp:Label>
</div>
</form>
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
</asp:Content>
The Form however with the CKEditor in it is not allowing to be initialized because it is becoming a Nested Form, since the master page itself is bound in a form.
How can I prevent this please?

Your CKEditorControl will inherit the form from the master page.
First, move your asp:ContentPlaceHolder from the head tag:
<head runat="server">
<title></title>
<!--DON'T PUT IT HERE-->
</head>
<body>
<form id="form1" runat="server">
<asp:ContentPlaceHolder ID="head" runat="server">
</asp:ContentPlaceHolder>
...
Now you can remove the form2:
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
<!--<form id="form2" runat="server">-->
<div>
<div>
<CKEditor:CKEditorControl ID="CKEditor1" runat="server">
</CKEditor:CKEditorControl>
...

</asp:content>
in your design page use like this.
<asp:Content ContentPlaceHolderID="ContentPlaceHolder4" Runat="Server">
<img id="img1" runat="server" />
</asp:Content>
and in code behind link button click event like below:
protected void lkbutton_click(object sender, EventArgs e)
{
img1.Src = "~/images/sonata-logo.png";
}
i tested it it's working fine.
but put the correct path of image then only it will show.
Thanks
<asp:LinkButton ID="LinkButton1" runat="server" width="250px" height="250">
<img runat="server" id="IL"src="~/Class/Adds/0/4.jpg" width="250" height="250" />
</asp:LinkButton>
With this you can change the picture with server code.
il.SRC = "~/Class/Adds/0/7.jpg"

CSS won't appear on one asp.net page, fine on others

I'm working on a project at the moment that I've recently taken over, which has the Umbraco CMS installed (4.7.1) and is written in ASP.net and I'm not really sure what I'm doing and have got stuck.
The CSS won't appear on one page, the ContactUs page (contact-us.aspx), but the CSS appears perfectly fine everywhere else, which I find really odd.
So my question is what do I need to do to get the CSS appearing on this page, like the others?
Here is the contact-us template:
<%# Master Language="C#" AutoEventWireup="true" CodeBehind="ContactUs.master.cs" Inherits="GreenHill.masterpages.ContactUs"
MasterPageFile="~/umbraco/masterpages/default.master"%>
<%# Register TagPrefix="gh" TagName="ProductNav" Src="~/usercontrols/ProductNav.ascx" %>
<%# Register TagPrefix="gh" TagName="ProductListing" Src="~/usercontrols/ProductListing.ascx" %>
<%# Register TagPrefix="gh" TagName="Twitter" Src="~/usercontrols/Twitter.ascx" %>
<asp:Content runat="server" ID="pageContent" ContentPlaceHolderID="content">
<div class="title">

<asp:Literal ID="litTitle" runat="server"></asp:Literal></h1>
</div>
<div class="brown-border"></div>
<table class="content">

</td>
</tr>
<tr>
<td>
<table class="small-table">

And finally there default.master template:
<%# Master Language="C#" AutoEventWireup="true" CodeBehind="default.master.cs" Inherits="umbraco.presentation.masterpages._default" %>
<asp:ContentPlaceHolder ID="ContentPlaceHolderDefault" runat="server">
</asp:ContentPlaceHolder>
<asp:ContentPlaceHolder id="content" runat="server">
</asp:ContentPlaceHolder>
You have:
MasterPageFile="~/umbraco/masterpages/default.master"
Which means your Contact Us page is inheriting from the default Umbraco master page, and not your base master page.
I just realized in typing this that your question is a week old, but I'm going to answer anyway. :)

This page is missing a HtmlHead control which is required for the CSS stylesheet link that is being added. Please add <head runat="server" />

Master pages should not contain form tags in general because they are meant to be used only as the base layout of your content page. Remove the form tag from the Master page and the error will go away.
If you want to define a common "Login" section for all your pages (this appears to be your intent), you can instead create a UserControl to do this. You would then define a section inside your Master page to contain this user control making sure that the ContentPlaceHolder of the Login UserControl always ends up enclosed inside the content page's form. That way, when you submit the form, the btnlogin_Click1 click event is triggered.
In conclusion: re-arrange your page in a way that you have one form tag per page, since ASP.NET does not allow having more than one and try to define your form's inside the content pages and not the Master page.

Cant bind the Master page to my Page

I'm new in ASP.Net and I want to creat a very simple form which bind to a master page but no success. this is my Master Page code:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<asp:ContentPlaceHolder ID="HeadContent" runat="server" />
</head>
<body>
<form runat=server>
<asp:ContentPlaceHolder ID="MainContent" runat="server">
<body>
<table width=100% border=1 style="background:black" >
<tr>
<td width=20%></td>
<td width=80%><asp:Label ID="Label1" runat="server" Text="Label"></asp:Label></td>
<td width=20%></td>
</tr>
</table>
</body>
</asp:ContentPlaceHolder>
</form>
</body>
</html>
and code of my page is:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<asp:Content ContentPlaceHolderID=HeadContent runat=server>
</asp:Content>
<asp:Content ID="MainContent" runat=server ContentPlaceHolderID=MainContent >
</asp:Content>
but hte table in the Master Page doesn't appear in the page.Would you please help me to solve this problem?
For starters,
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<asp:Content ContentPlaceHolderID=HeadContent runat=server>
</asp:Content>
<asp:Content ID="MainContent" runat=server ContentPlaceHolderID=MainContent >
</asp:Content>
is entirely wrong.
The DOCTYPE should be listed in the master. Secondly:
<asp:Content ID="HContent" ContentPlaceHolderID="HeadContent" runat="server">
</asp:Content>
<asp:Content ID="MainContent" runat="server" ContentPlaceHolderID="MainContent" >
</asp:Content>
Would more closely match your intent. But one flaw in your style, as it were, and this is strictly a style thing:
<asp:Content ID="HContent" ContentPlaceHolderID="HeadContent" runat="server" >
</asp:Content>
<asp:Content ID="MainContent" ContentPlaceHolderID="MainContent" runat="server" >
</asp:Content>
Notice how I put runat="server" at the end, on both tags? Always put that at the end, it'll make it easier to make sure you've put it in the right place. Alternately, always put it right before ID
Edit:
<asp:ContentPlaceHolder ID="MainContent" runat="server">
<body>
<table width=100% border=1 style="background:black" >
<tr>
<td width=20%></td>
<td width=80%><asp:Label ID="Label1" runat="server" Text="Label"></asp:Label></td>
<td width=20%></td>
</tr>
</table>
</body>
</asp:ContentPlaceHolder>
Where you have this in the master page, the contents of the ContentPlaceHolder won't be shown when a child page implements this section. You'll need to move those outside of the master page ContentPlaceHolder declaration. This concept is very "either or" and there is no room to have an alternate opinion. It was written this way on purpose.
Perhaps you want:
<asp:ContentPlaceHolder ID="MainContent" runat="server" />
<body>
<table width=100% border=1 style="background:black" >
<tr>
<td width=20%></td>
<td width=80%><asp:Label ID="Label1" runat="server" Text="Label"></asp:Label></td>
<td width=20%></td>
</tr>
</table>
</body>
Are you specifying the master page in your #Page directive?
For example:
<%# Page Language="C#" MasterPageFile="~/MasterPages/Master1.master" Title="Content Page"%>
