i want to disable validation controls on some conditions. how can i find that a control is inherited from "BaseValidator"?
note all validator controls are inherited from BaseValidator (+)
In my MVC project, I am trying to setup a base product class that will be inherited by a more specific class later. Here is my scenario. I have a table called ProductBase, it contains three fields, BaseProductId(PK), CatalogNum, and ListPrice. Every product in the system will share these attributes. Next, I have a table called Shirt, with three fields BaseProductId(PK, FK), Color, and Size.
I then setup an Entity Data Model that pulled in both of these tables and created classes BaseProduct and Shirt. So, in my model, I want to do something like this:
[Code]....
The main problem I have with this, is that if I do any kind of condition on CatalogNum or ListPrice, then my performance goes to crap. One of the main things we will want to do is something like this:
[Code]....
This takes an enormous performance hit, and I suspect it is because the partial class above returns to the database for each shirt.
The other problem I have with this approach, is that I cannot force the properties for the Shirt. What if I make a change to the BaseProduct? What happens when I have multiple product types, will I have to repeat this code? I assume I will need to make a change with the entity data model, but I am unsure where to begin.

View 5 RepliesI've created a base page type that derives from WebViewPage<T>.
I'm using a StructureMap implementation of IDependencyResolver to inject dependencies using setting injection
i.e.public ISomeService SomeService {get;set;}
Whilst this works fine on a normal view page, my services are not injected on a Layout page.
Are the base types for a standard view page and layout page the same?
If I call IDependencyResolver directly in the base page type then it works fine but I would prefer not to do this.
I have created inherited textbox control using windowscontrol library project.the code is here:
Public Class MyTextBox
Inherits System.Windows.Forms.TextBox
Public Property sanText() As String
[code]...
I implemented a lot of ASP.NET controls inheriting controls from existing control library. My problem is that I can't use existing library themes/ skin files for skinning my controls. Is there a way to use existing skin files in inherited controls? Changing parts or renaming skin files is not an option. I could read data from skin file and then apply it to control programatically. Is there some kind of API for reading skin files?

I am Confused about the TextReader Class,that how it fetched data ?And from where it fetches data?
Is this the base class of all other Reader type classes?
i am tryin to make an inherited custom label control.
what i want is i want to have a property for the label where one can select languages.
like <label id="lbl" language="">
so when the user gives "language" property he must be provided with an option of "EN" and "AR" like an intellisense.
regarding the following issueCode
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Test.aspx.cs" Inherits="Ajax.Test" %>
<%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="cc1" %>

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.
I put a server side button on the header page. The website is running fine. I use the same source and put it on IIS, it's also working fine but the problem is, i couldn't compile it anymore using my VS studio. It's showing no error so when I go and check the output (after scrolling down a bit and found one line says error). it says
C:InetpubwwwrootAmFraserIntranetheader.master.vb(31,0): error BC30506: Handles clause requires a WithEvents variable defined in the containing type or one of its base types.
C:InetpubwwwrootAmFraserIntranetheader.master.vb(32,0): error BC30451: Name 'keyword' is not declared.
keyword is the textbox on the header page. I also played around with AutoEventWireUp (true/false) and defining onclick event on the server tag but it is still not solving the problem.
If the answer to this question exists somewhere, I'm no good at searching for it. This is sort of a simple question, the response being two parts: (1) is it possible? (2) if so, how?
I've created a web user control for my site's footer. In my web.config I have it registered like this:
[Code]....
Then, within the pages on my site, I simply insert it like this:
[Code]....
But obviously, that didn't work. I get this error: The type or namespace name 'FooterControl' could not be found (are you missing a using directive or an assembly reference?)
So I'm really not sure what to do at this point. I can put all of my code in the ASPX file and make my life easier, but I would kind of prefer not to.
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 new in asp .net.I am not able to undestand why we call base class method when we
override methods/events.Like automatically visual studio will put base.OnInit() if you are overriding OnInit.
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
}
same is the case of Finalize. In derived we call base.Finalize() Is there any need of calling these base class methods ?
I have to implement User base security in my Web project using .Net3.5. Followings are some we need:
Roles can be Admin, Manage, Editor, Member etc User can have multiple roles Every roles has its own dynamic menus and restrictions/resources All menus and interface will populate dynamically from Database
I heard some where this kind of i.e user base security can be implemented using HashTable but I dont know how is it?
Today I came to know that for this kind of work Java people use Interceptor Design patterns. So, how could I do the same in asp.net C#?

I'm receiving the following error when deploying a feature containing ASP.NET pages to our development SharePoint servers: System.InvalidOperationException: The type specified in the TypeName property of ObjectDataSource 'odsYears' could not be found. Our .dll is being deployed to the GAC and our pages are being deployed to the the respective Features directory in the 12 hive. We are not receiving this error on our Sandbox SharePoint server. I disassembled the .dll to be sure the class was being deployed and everything looked ok. why this would not work on one of our SharePoint environments?
View 2 RepliesHow to find the control type in javasccript?. Say if i have an ASP.NET LinkButton and i wanna find control type from the javascript. How can i do that. I tried using typeof(), but it giving me an object back. and i tried

I have a user control in silverlight which contains both XMAL and .cs file. But I wanna make it into a base control. In other word,I can make a control inherited it whose area in it can be edited. Just like Master Page in asp.net,you know. In the base control,I only have a lot of description in XMAL,perhaps it can be described in the .cs file,too.
View 1 RepliesIn a recent post, I expressed a need to access the properties for the body using declarative syntax, see
Contentplaceholder for replacing attributes?
But, the syntax confuses the editor which is not acceptable.
My hypothesis for a workable solution is to make the change in code. To derive a class from System.Web.UI.Page with extended functionality. However, I want for the designer to be able to still use declarative syntax to set the body tag.
I do not want to have to change any code in my aspx web pages except that they derive from base I want to be able to set these properties using declarative syntax, merely by adding a tag in the derived page I'm not immediately sure how to go about doing this because it doesn't exactly fit the OOP paradigm and I'm not sure where the changes need to be made.
I can use a findcontrol in the base to see if the placeholder has been added. But, not sure exactly at what point in the page processing lifecycle that I can use this findcontrol. I need to set the body before it renders but also be able to grab something from the declarative code.
Is it possible for a derived controls to inherit his base control skin.
Say I am deriving a control from TextBox, is it possible for the derived control to inherit the skin settings for Textbox or do they need to be defined again?
I am applying the default skins to all controls through the styleSheetTheme Page property I am using the Devexpress asp.net controls if that makes any difference.
I have a progress bar (which is a user control). When user, click a button, this progressbar will get displayed. The issue is ...even if the progressbar is visible, I am able to set focus to other controls in base page. I need to blur the base page...and set focus to user control.
View 2 RepliesI have a base user control (inherited from System.Web.UI.UserControl)
public delegate void MyEventHandler(object sender, MyEventArgs e);
public event MyEventHandler ControlLoaded;
//Fire the event from here
protected override void OnLoad(EventArgs e)
{
MyEventArgs cmdEventArgs = new MyEventArgs("somearg");
ControlLoaded(this, cmdEventArgs);
}
I have several controls that are derived from this base user control.
On the host ASPX page, I need to subscribe to the ControlLoaded event.
protected void Page_Load(object sender, EventArgs e)
{
//subscribe to the event
//This line DOES NOT WORK as I cannot attach event to a base control - It needs an instance of the user control which I don't have
BaseUserControl.ControlLoaded += new MyEventHandler(ControlLoaded);
}
private void ControlLoaded(object sender, MyEventArgs e)
{
// some control has been loaded
}
How do I subscribe to the ControlLoaded event?
