Using Code Blocks In Head Content And Link Tags?

Feb 1, 2010

I'm building an asp.net app using themes, and I've assigned a theme to the app using the web config.

I have a bookmark icon that I want to use for my page and it is located in the themes directory, but I am having trouble referencing the themes location from a link tag in my header.

First I tried putting a code block inside the link tags href element, which did not work. Instead all it did was html encode the <% characters and output it directly to the browser:

<link rel="shortcut icon" href="/App_Themes/<%=Page.Theme %>/images/bookmark.ico" type="image/x-icon" runat="server"/>

I am able to put a code block inside an element in an hr tag though, so I don't know why it won't work in a link tag:

<hr test="<%=Page.Theme %>"/>

Then I tried doing a Response.Write inside the head tag, but I got an error saying the Controls collection cannot be modified because the control contains code blocks:

<% Response.Write("<link rel="shortcut icon" href="/App_Themes/" + Page.Theme + "/images/bookmark.ico" type="image/x-icon"/>"); %>

I also tried it just with a string literal, and got the same error:

<%= "<link rel="shortcut icon" href="/App_Themes/" + Page.StyleSheetTheme + "/images/bookmark.ico" type="image/x-icon"/>" %>

Is there any way to reference something from the themes directory inside the link tag?

I'm trying to do this in both an ASP.NET 2 and an ASP.NET 2 MVC app.

Custom Control Render JavaScript Code In Head Tags?

Feb 3, 2011

I am creating a custom control and was wondering if it is possible to render any JavaScript in the head tags of the page it is placed on? I am thinking I would need to use the FindControl method, but am not sure what I need to bind to. I am thinking the page object? Let me know if I am thinking in the right direction or if there is another option.

My only concern with the above mentioned idea is that how do I render all my content while placing some code in the head tags?

Why Does URLs Get Encoded In <link> Tags Within <head Runat="server"> And How To Avoid It

Jan 4, 2011

(I have tested this with a vanilla asp.net site running from the webdev server and it is a problem here also):

I have the following markup in my .master file

[code]....

Clearly Asp.Net does something to encode the url. As it happens, I really need the head tag to be runat="server" and I would also like to be able to have "&" in link-urls within it is there some trick I can use to have my cake and eat it too?

Server Removes Spacing Between Head Tags

Jun 11, 2010

I haven't been able to find relevant information through searches. I'm very green when it comes to sever side scripting. I have an ASPX page with a standard form. In the head I have meta tags, the title tag, and a link tag neatly ordered on their own lines. However, when viewing the source code after publishing to the server, the spacing between the tags is removed and it looks quite messy. (There are also <style> and <script> tags that follow, but they remain unaffected.)

I realize this has no practical effect on the site itself (in an SEO sense or otherwise). My project manager shows the source code to our clients to educate them on meta tags and page titles. It would help if it wouldn't become jumbled like this. I wonder if this is a common issue and if it's possible to prevent through better coding practices. HTML as authored, with tags separated on their own lines:

HTML Code:

<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta name="description" content="Welcome to Lawn Care Waukesha - Cut My Lawn. Cut My Lawn - Lawn Care Services has offered quality lawn cutting, fertilizing, aerating, and much more at affordable pricing since 2002! We currently offer lawn care service to Waukesha, Brookfield, Pewaukee, Menomonee Falls, and surrounding communities." />
<meta name="keywords" content="lawn cutting, lawn mowing, lawn care, fertilizing, aeration, mulching, shrub trimming, lawn mowing, edging, pruning, mulching, weed control, waukesha, Brookfield, Pewaukee, menomonee falls" />
<title>Lawn Care Waukesha ó Cut My Lawn, Lawn Care Service</title>
<link rel="shortcut icon" type="image/x-icon" href="favicon.ico" />
HTML after being processed by the sever, with all the tags running together:

HTML Code:
<head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><meta name="description" content="Welcome to Lawn Care Waukesha - Cut My Lawn. Cut My Lawn - Lawn Care Services has offered quality lawn cutting, fertilizing, aerating, and much more at affordable pricing since 2002! We currently offer lawn care service to Waukesha, Brookfield, Pewaukee, Menomonee Falls, and surrounding communities." /><meta name="keywords" content="lawn cutting, lawn mowing, lawn care, fertilizing, aeration, mulching, shrub trimming, lawn mowing, edging, pruning, mulching, weed control, waukesha, Brookfield, Pewaukee, menomonee falls" /><title>
Lawn Care Waukesha ó Cut My Lawn, Lawn Care Service
</title><link rel="shortcut icon" type="image/x-icon" href="favicon.ico" />

I'm not sure it's relevant, but here's the script used to send the form (which I didn't write, by the way). It's the final tag inside the page head:

HTML Code:
<script type="" runat="server">
Protected Sub SubmitForm_Click(ByVal sender As Object, ByVal e As System.EventArgs)
If Not Page.IsValid Then Exit Sub
Dim SendResultsTo As String = "email"
Dim smtpMailServer As String = "smtp"
Dim smtpUsername As String = "email"
Dim MailSubject As String = "subject"
Try
Dim txtQ As TextBox = Me.FormContent.FindControl("TextBoxQ")
If txtQ IsNot Nothing Then
Dim ans As String = ViewState("hf1")
If ans.ToLower <> txtQ.Text.ToLower Or ans.ToUpper <> txtQ.Text.ToUpper Then
Me.CutMyLawnForm.ActiveViewIndex = 3.......................

Resolve Code Blocks At Runtime (C#)?

Feb 3, 2011

I am writing a dynamic control that I want to pass in something along the lines of the following:

HyperLink myLink = new HyperLink();
myLink.NavigateUrl = "/Home.aspx?id=<%= DataBinder.Eval("PageId") %>";
myLink.Text = "The link";
myControl.Controls.Add(myLink);

I want to be able to resolve the myLink.NavigateUrl at run-time according to the context that myControl puts the control into in the end (this is not a WebControl and therefore adding to the collection of controls doesn't output to page).

How To Use If Statements With Razor And Inline Code Blocks

Jan 22, 2011

I'm updating my old .aspx views with the new Razore view engine. I have a bunch of places where I have code like this:

<span class="vote-up<%= puzzle.UserVote == VoteType.Up ? "-selected" : "" %>">Vote Up</span>

Ideally I'd like to do this:

<span class="vote-up@{puzzle.UserVote == VoteType.Up ? "-selected" : ""}">Vote Up</span>

However there's two problems here:

vote-up@{puzzle.UserVote .... is not treating the @ symbol as a start of a code block @puzzle.UserVote == VoteType.Up looks at the first part @puzzle.UserVote as if it's supposed to render the value of the variable.

The Controls Collection Cannot Be Modified Because The Control Contains Code Blocks

C# - Controls Collection Cannot Be Modified Because The Control Contains Code Blocks?

Aug 11, 2010

I recently put some code <% %> code blocks in my Master Page. Note I've read of the "fix" for either moving things out of <head> or using <%# %> but neither of them work well for my application.

Now the weird thing is that I only get this error on one page of mine. All the other pages seem to work fine, so what actually causes this error? There is nothing I can think of that is unique about this page. It uses the script manager as does other working pages and there is just nothing extraordinary about this page. It does have quite a few custom controls on it, so hunting down what is different in this page is more difficult than usual.

So what actually causes the Controls collection cannot be modified because the control contains code blocks exception?

VS 2010 - ItemTemplate (Code Blocks Are Not Supported In This Context)

Nov 21, 2013

We are using Infragistics' WebDataGrid, but this question probably applies to all other grids. I am new to Infragistics (actually have worked with their controls years ago, but feeling new regardless!) and this application as well. So I'm looking to its existing code as a model.

I want to have a column called Tobacco with a Y or N value depending on if Smoker is true/false.

Ideally, the whole thing would be something like this:

Code:
<ig:BoundDataField Header-Text="TobaccoUse" Key="Smoker">
<ItemTemplate>
<%# DataBinder.Eval(Container, "DataItem.Smoker") != DBNull.Value ? (DataBinder.Eval(Container, "DataItem.Smoker") == true ? "Y" : "N") : "N"%>
</ItemTemplate>

Because I want to check for a null first and when I know I don't have one, test the value.

But since I am getting an error on that I am trying to start simple and build it up. I am getting the same error on this:

Code:
<ig:BoundDataField Header-Text="TobaccoUse" Key="Smoker">
<ItemTemplate>
<%# DataBinder.Eval(Container, "DataItem.Smoker") == true ? "Y" : "N"%>
</ItemTemplate>

The error is: Code blocks are not supported in this context.

Why is this a code block and should it be something else? What is my context?

This is an example of a line that works:

Code:
<ig:TemplateDataField Header-Text="DOB" Key="DOB">
<ItemTemplate>
<%# DataBinder.Eval(Container, "DataItem.DOB") != DBNull.Value ? Convert.ToDateTime(DataBinder.Eval(Container, "DataItem.DOB")).ToShortDateString() : ""%>
</ItemTemplate>
</ig:TemplateDataField>

I don't know if I need a Convert.ToBoolean in there somewhere but I tried and it didn't work and at this point I am just guessing which will take a long time for me to get it right.

Inject Code Into Masterpage / Html Head From A User Control?

Jan 10, 2010

I am struggling with something that I guess should be standard practice really. I have a number of user controls that use some JQuery plugins. I do not really want to link to the extra CSS and JS files from my main masterpage as this would cause extra load to the user the first time they hit the site, (admittedly it would only be the once), so I was just putting them links into the top of the user control. Then I looked at my source HTML, not nice! Even worse for controls that repeat multiple times on a page.

So I was thinking is there a way of injecting them into the Head of the page when they are needed from the User Control. For that matter is there a way of doing it to the footer for JS stuff?

AJAX :: Ajaxtoolkit Version 4 - Error 'The Controls Collection Cannot Be Modified Because The Control Contains Code Blocks"

Sep 23, 2010

I was working on an asp.net 3.5 website and used ajaxtoolkit in it and when I use it in my page it was registered as below

<%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="cc1" %>

and it was working well even After I upgraded my wevbsite to .net version 4 but when I started a new website from scratch in vs2010 using .net4 when I use ajax toolkit in this new site it is registered as folowing

<%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="asp" %>

and when I run the page I get the error The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>) I don't Know what is the reason for this. I noticed another thing. in my old website I was using thckbox script by using the files common.js, jquery-1.3.2.js,jquery.thickbox.js and puting them in a Javascript folder ad then registering them in Script manager as following

<asp:ScriptManager ID="ScriptManager1" runat="server">
<Scripts>
<asp:ScriptReference Path="~/Javascript/jquery-1.3.2.js" />
<asp:ScriptReference Path="~/Javascript/jquery.thickbox.js" />
<asp:ScriptReference Path="~/Javascript/common.js" />
</Scripts>
</asp:ScriptManager>

this was working well also but in my new site the jquery file version was jquery-1.4.1.js but also I added the old version f the javascripts files in the built in Scripts folder that is created by default b the new site and followed the same way in registering them in the script managerchange the JavaScript folder to the built in folder Scripts

<asp:ScriptManager ID="ScriptManager1" runat="server">
<Scripts>
<asp:ScriptReference Path="~/Scripts/jquery-1.3.2.js" />
<asp:ScriptReference Path="~/Scripts/jquery.thickbox.js" />
<asp:ScriptReference Path="~/Scripts/common.js" />
</Scripts>
</asp:ScriptManager>

but this doesn't work also in the new site I think that there is something diffirent in the 2 case which leads to this change in performance I wish your support and advice about how to solve this matter

How To Organized Page Specific CSS Link Tags With Spark View Pages

Mar 12, 2010

I'm currently using ASP.NET MVC 2 and the spark view engine. The main master page (application.spark) contains all of the CSS link tags that need to be present for all pages (global stuff). However, I have some content pages that have page specific CSS tags and currently I'm just sticking the link tag in the body as something like:

<content name="MainContent">
<!-- page specific csss -->
<link rel="stylesheet" href="/Content/css/page_specific.css" />

My problem is that when the page renders, this tag ends up in the which is not where it needs to be. Is there a solution for this?

I had was to check the controller in the Application.spark page and write out which page specific css file is required for that particular controller, however, that solution doesn't seem to scale well and I would imagine there is some way of creating the link in the child page and having it render where it's supposed to by the browser.
