However, when I want to assign the property on any aspx file, it does not show in intellisense and when I use it it said it is a invalid attribute of element "Page".So, 2 question.How do I make it such that it shows up in intellisense?Can I set any localize variable as a value of the property in the page directive?here is the property on my base page:

I noticed a behaviour in Visual Studio that the design tab for aspx page does not work if I use a dynamic master page using a base page. I dynamically set the master page to implement theming. It shows a master page error and says "The page has controls that require a Master Page reference, but none is specified".
Is there any solution? Or any work around?
I currently set the base/master page to a default master page in the page for myself and work on the page. Once I complete the page, I remove the master page attribute. I wanted to know if some better method is available.

I m having little misunderstanding that how basepage inheritance work in asp.net. I saw this example [URL] and others and I just have questions to get better understanding on the articles: Do we always need override type function in base page even if we dont want to overwrite in child page. What is the purpose of "MyBase.OnLoad(e)"?
' -- VB.NET
Public Class MyBaseClass
Inherits System.Web.UI.Page
Protected Overrides Sub OnLoad(ByVal e As EventArgs)
'... add custom logic here ...
'Be sure to call the base class's OnLoad method!
MyBase.OnLoad(e)
End Sub
End Class

I am feeling that I have terribly wrong somewhere. I was working on a small asp.net app. I have some dynamic themes in the heme folder and have implemented a page base class to load the master page on the fly. The master is having the ContentPlaceHolder like: <asp:ContentPlaceHolder ID="cphBody" runat="server" />
Now I am adding pages that are derived from my base class and added the form elements. I know, Visual Studio has problem showing the page in the design mode. I have a dropdown box and wish to add the event of onselectedindexchange. But it is not working. the page is like this:
<%@ Page Language="C#" AutoEventWireup="true" Inherits="trigon.web.Pages.MIS.JobStatus" Title="Job Status" AspCompat="true" CodeBehind="JobStatus.aspx.cs" %>
<asp:Content ID="Content1" ContentPlaceHolderID="cphBody" runat="Server">
<div id="divError" runat="server" />
<asp:DropDownList runat="server" id="jobType" onselectedindexchange="On_jobTypeSelection_Change"></asp:DropDownList>
</asp:Content>
I have also tried adding the event on the code behind like:
protected void Page_Load(object sender, EventArgs e)
{
jobType.SelectedIndexChanged += new System.EventHandler(this.On_jobTypeSelection_Change);
if (!IsPostBack)
{
JobStatus_DA da = new JobStatus_DA();
jobType.DataSource = da.getJobTypes();
jobType.DataBind();
}
}
protected void On_jobTypeSelection_Change(Object sender, EventArgs e)
{
//do something here
}

I have a custom basepage and a master page in my web application. In my master page, there are events that I run from each page in my web application. Instead of putting the code in each of my pages, I decided to create a base page that each web page will inherit from. Trouble is, I cannot get the base page to invoke the events on the master page.

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.

How do I create a new event in a base page class that fires after all derived pages have fired their load events but before any controls fire their load events.
The following code fires the event before the derived page's load event. I want it to fire the event after the derived page's load event but before all control load events:
Base Class:
Public Event FirstLoad(ByVal sender As Object, ByVal e As System.EventArgs)
Private Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not IsPostBack Then
RaiseEvent FirstLoad(sender, e)
End If
End Sub
Derived Class:
Private Sub Page_FirstLoad(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.FirstLoad
'Stuff here happens before controls load but only on first page loads'
End Sub

I have a web page (Orders.aspx) that gets some orders and show them in a Gridview .The orders list I get from DB is depend on a field named Status. The page has a master page that contains a Tab user control. The user control has several tabs and every tab has a different Status. Therefor, when the user clicks on every tab, I want to pass a value as status to my content page (Orders.aspx) and then select the orders from DB based on status.

I can have a base class for views in an MVC project like this:
public class BaseViewPage : System.Web.Mvc.ViewPage
{
public string Something { get; set; }
}
And then in the ASPX I can do this:
<%@ Page Something="foo" Language="C#" Inherits="MyNamespace.BaseViewPage" %>
This works fine; the problem is when I try to do the same with the generic version:
public class BaseViewPage<TModel> : System.Web.Mvc.ViewPage<TModel> where TModel : class
{
public string Something { get; set; }
}
When I try to use this from the ASPX, like this:
<%@ Page Something="foo" Language="C#" Inherits="MyNamespace.BaseViewPage<SomeClass>" %>
I get the error message:
Error parsing attribute 'something': Type 'System.Web.Mvc.ViewPage' does not have a public property named 'something'.
Notice how it tries to use System.Web.Mvc.ViewPage rather than my BaseViewPage class. To make it more interesting, if I remove the "Something" attribute from the Page directive and put some code in the generic version of BaseViewPage (OnInit for example) the class is actually called / used / instantiated.
So, am I doing something wrong or is this a limitation.

So what I'm trying to accomplish is this
[Code]....
The user control has public properties named accordingly and the page has protected properties accordingly which I've verified have the desired values.
For some reason the values are always empty strings or 0s in the usercontrol, no matter what the page property is.

In a webforms app, I used to be able to access the master page to hide a link as follows through a property...
protected void Page_Load(object sender, EventArgs e)
{
HeaderFooter m = Master as HeaderFooter;
m.ShowHomePageLink = true;
}
However, when I try this in my MVC View, I can access the property but it doesn't hide the link as expected. It's as if the View is already rendered.
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
<%
MyApp.MasterPages.HeaderFooter m = Master as MyApp.MasterPages.HeaderFooter;
m.ShowHomePageLink = true;
%>
...
</asp:Content>

FROM BOOK: To reference public properties in a master page, we add the @MasterType declaration to the content page and reference the property using Master.<PropertyName>.
QUESTION: But what happens internally? Does all of the master's and content page's properties, function gets complied into one class? Or something else?

I have a Master Page which has an associated css file. On one of the base pages I have a div to which I am trying to apply a style from this css file by id. However, the page when rendered has a different id for this element. How can I specify the correct id name in the css file? Is there a way to specify that I want the id of this element like there is in javascript using the <%= Element.ClientID %>?

I'm workng on a new, green-field ASP.Net application. We're implementing a base page which all pages will be, er, based on. The application will be running under Integrate Windows Auth, so I'll have the user's account details. With these, I'll be going to several databases (in which the user will exist) to find out what roles they are assigned to in each db. I'll be holding the role yay/nay in a bool array, and key into it via an enum.
There will be a session object that will hold a few things, and the roles assigned for that user. I'm thinking of making the session object available as a property of the base page, as the code would be something like this:
public SessionObject MasterSessionObject
{
get
{[CODE]....
But, I'm sure you'll agree, it looks sucky...If there was a CheckSecurity method on the base page, it would have to take a concrete DatabaseRoles object, but also an enum of which role to check, which would also look sucky. And finally, there would be a requirement at a later date to add more databases and their security settings...
I'll add code tomorrow if required... :-s
I dunno, I'm not that thick, but I do have a hard time sometimes binding all this together...

I've tried setting the <pages pageBaseType="DynamicWebPage" /> value in web.config, but when I response.write out the page type, I'm still getting Microsoft.WebPages.WebPage.
I'm simply trying to sub-class WebPage and add some additional functionality such as a dynamic PageData dictionary similar to Phil Haack's dynamic ViewData dictionary.

I have an asp.net project, and I load a base aspx page to display to the user. Then I ajax in the results of an ascx component and inject it via innerHTML in javascript. I have noticed that the ascx component loads slowly on the first page load, but instantly thereafter. This is really cool, but I do not understand how this can be cached, as the contents are generated by making several db calls. Does the server send some kind of hash to compare the contents to, to see if it changed on the server or not? Is this a browser thing or an asp.net thing?
