What Is A Page Directive
Oct 10, 2010
I'm studying up for a Microsoft Certification exam, and some of the wording for the 'content' in the examn confused me. In the MS exam website, under Developing Web Form Pages, it says in regard to the content on the exam...
This objective may include but is not limited to: page directives such as ViewState, request validation, event validation, MasterPageFile; ClientIDMode;
I was under the impression that a page directive referred to the @Page keyword, and the associated values defined in the @Page section were attributes/properties. But the wording of the exam content almost implies that the attributes/properties of the @Page keyword are directives.

I am receiving a Parser Error with all my pages in a particular folder:
Parser Error Message:
The file '/railroad/freightcars/covered_hopper/MasterFiles/Freightcars.master' does not exist.
Line 1: <%@ Page Title="Freight Car Photos - CP Covered hoppers - CoveredHopperPhotos.com" Language="C#"
MasterPageFile="~/MasterFiles/Freightcars.master" AutoEventWireup="true" CodeFile="cprail.aspx.cs" Inherits="railroad_freightcars_covered_hoppers_cprail" %>
It seems like the ~ is not resolving; none of my .aspx pages in this folder work. All my pages in several other folders work fine.
I had this problem with another folder when i first published pages to a folder named covered_hoppers. Since i couldn't figure out the problem, i renamed the folder to covered_hopper and re-published.. all worked fine for a couple of months until yesterday. Now i am having the same problem. No problems on my local copy; never had this error with any other folder in my site.

I am working on an MVC site using NHaml for the view engine.
I have a page that needs to submit HTML code as a form value and am getting the System.Web.HttpRequestValidationException thrown at me.
I want to specify the <%@ Page validateRequest="false" %> so that this page will allow this data to be submitted but am unsure on how to do this with NHaml generating the pages.
The editor I was using was TinyMCE and I found that it has an option for encoding the output, that way it doesn't trigger the anti-html validation.

I have been trying to find a way to declare two classes using page directive, but it seems like mvc framework doesnt support it.
I have got :
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<IEnumerable<ContactManager.Models.contact>>" %>
which shows the list of the contacts including edit delete and create option.
What I need to declare another model class which is FileRepository.cs for uploading files on the same page. In this case the page directive should be like:
2. <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<IEnumerable<ContactManager.Models.FileDescription>>" %>
Is there any way I can incorporate both into one as the first is coming from the database.

The docs for @MasterType have this example.
<%@ Page masterPageFile="~/MasterPage.master"%>
<%@ MasterType virtualPath="~/MasterPage.master"%>
Why is @MasterType even needed? Couldn't the compiler automatically take the same actions based solely on @Page masterPageFile? When would you not want to use both?

I am having trouble with the performance of a web site... Some SQL queries are killing the server. But, as the title of this post mention, I looked at the OutputCache page directive to improve performance of the site. Although, I came across some questions regarding this directive:
1- If I have a web-user control that declares an OuputCache directive in a page that has one too, which one will "win"?
2- What's the best pratice regarding the duration ? I'd love to have a sliding window too.

i designed an export to excel page that uses the following code
the data is displayed in grid view and the date format is displayed as M/d/yyyy
so i added the culture en-GB to page directive to display the date as d/M/yyyy
the date now displays correctly d/M/yyyy, and the utf-8 also display correctly in gridview.
however once i export to excel the utf-8 appears scrambled
when ever i remove the culture from page directives, names display correctly, however i face again the M/d/yyyy issue.
My question is: is there a way to display date as d/M/yyyy and at the same time reading correct utf-8

Is it possible to set the Inherits attribute of an ASPX Page directive to a class in an arbitrary assembly?
I need to modify an ASP.NET (1.1) application for which the source code was lost. In a new assembly (foo2.dll) I've created a replacement code-behind class that derives from the original class in the site's code-behind assembly (foo.dll). It seems easy enough to set the Inherits attribute of the Page directive to the new class name, but when I do that the web server gives me Could not load type 'Foo2.checkout2'. I am referencing the new assembly in the <assemblies> section of Web.config.
I don't see anything in the documentation to indicate that this scenario is unsupported, but I'm not certain that it is, either.
Original
<%@ Page Inherits="Foo.checkout" language="c#" Codebehind="checkout.aspx.cs" AutoEventWireup="false" %>
New
<%@ Page Inherits="Foo2.checkout2" CodeFile="checkout2.aspx.cs" CodeFileBaseClass="Foo.checkout" language="c#" Codebehind="checkout.aspx.cs" AutoEventWireup="false" %>

OK, so I'm trying to create a template item from a web form.
I have referenced this article: [URL] and it exports the template and installs it fine.
When you try and use the template item within a project though it leaves the inherits="_Default" in the page directive like shown below:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="FormTemplateDev.aspx.cs" Inherits="_Default" %>
So it thinks all the new template items use the original form name pre-template generation. This is an issue in the code behind too as shown here:
public partial class _Default : System.Web.UI.Page
I have seen example of passing paramater strings through but havent managed to get anything to compile. I found something like below:
public partial class $safeitemname$ : System.Web.UI.Page
This was the link to the list of available template parameters i found:

As that title says my aspx page shows a compile error on the @Page directive that says "ASP.NET runtime error: Cannot load file or Assembly 'Microsoft.SqlServer.BatchParser' or one of it's dependencies". The project compiles with our error and it runs with no problem. The only real problem that this causes it that the intellisense for anything other than simple HTML is broken so I can't type asp:Controlname and have intellisense show me a the list of items or properties in a control. I get a green squiggly line under all the asp tags saying "Unrecognized tag prefix or device filter 'asp'". This project doesn't directly use SQL SMO but it does reference a project that does. However, I removed that reference and the problem still doesn't go away. I have installed on my development machine the full SQL client and for both SQL 2005 and 2008 (including the SDK) from the Developer editions of both versions. This was not a problem on VS2005 and the project compiles without error in VS2010 too.

I would like to parse QueryString and put the ID value to the ImgUrl path, I am trying this code:
<asp:Image ID="imgImageNormal" runat="server" ImageUrl='<%# string.Format("ImageHandler.ashx?ID={0}",Request.QueryString["ID"].ToString()) %>'/>
But the produced result is none. I am not getting any error message but after viewing the source of the page, this is the output for the image:
<img id="ctl00_ContentPlaceHolder1_imgImageNormal" src="" style="border-width:0px;" />
What am I doing wrong?

I inherited a really weird ASP.NET application where every .aspx page is basically a WebControl that acts as a surface for every other control that page is supposed to render/display.
One such page has a DropDownList -- I wanted a very simple thing that people do every day, namely to cause a postback when user changes a selection in it. I thought all I had to was set dropDownList.AutoPostBack = true, but after the page is rendered, when I see the generated HTML, I notice that there is no "onchange = __doPostBack(...)" code for the dropdownlist. Consequently selection changes don't do anything. Before I spend too much time digging into this, is there something obvious I am missing?

I am loading .aspx and .ascx files as StreamReader.
I want each file to register it's javascript and stylesheet dependencies in some declaration like a <%@ ClientDependency path="~/Scripts/jquery-1.4.1.min.js" %>.
Is there an existing convention for doing such a thing? I don't need an implementation, but I don't want to create a new syntax if there is already a way to do it.
Also, what are the guidelines for custom <%@ blocks in ASP.NET?

If I use the webforms view engine with MVC3, using an import directive on a strongly typed view causes a compile time error.e.g, given the fully qualified model class ImportBug.Models.TestModel,
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<TestModel>" %>
<%@ Import namespace="ImportBug.Models" %>

My master page looks like:
<head runat="server">
<title>
<asp:ContentPlaceHolder ID="PageTitlePlaceHolder" runat="server" />
</title>
Content pages look like:
<asp:Content ID="TitleContent1"
ContentPlaceHolderID="PageTitlePlaceHolder" runat="Server">
My Page
</asp:Content>
This works by placing the content page specific title on the page ("My Page" in this example). Now I want to add a global prefix to the title in my master page for the site name. So I want:
<head runat="server">
<title>
Example.com:
<asp:ContentPlaceHolder ID="PageTitlePlaceHolder" runat="server" />
</title>
However, when I do this content pages are still rendered without "Example.com" in the tile, it's like it's ignored.
Why is this happening and how can I achieve this?
