I have a solution with quite a few different MasterPages / BasePages which all inherit from somewhere else. My problem is that I have a virtual string in BaseMaster, which is overridden by BaseManagement, but when I try to access this string I always get the base valueThe point of inheriting masters and pages is obviously to avoid having duplicate code everywhere.

I have a MasterPage (MasterPage.master) with 2 child MasterPages (specialMaster.master and standardMaster.master). From the MasterPage.master I need to get at some of the controls in one of the children, specialMaster.master, say for example to hide certain
content if a session variable is not null.
I have a SharePoint 2007 Server and want to create a site with a nested Master Page.I created a new Master Page, test.master:
<%@ Master MasterPageFile="~masterurl/default.master" %>
<asp:Content ID="Content1" ContentPlaceHolderID="PlaceHolderMain" runat="server">
Test123
<b>
<asp:ContentPlaceHolder runat="server" ID="TestPH" Visible="true" />

I´m having a little trouble finding a radiobutton on a nested masterpage.
I tried this code.
//Principal principal = (Principal)this.Page.Master;
I'm changing the CSS of my menu items during runtime to reflect which page is currently being viewed. It works fine. But, I have a nested master page that needs to change the CSS of the master page's items. How I can access the master page's menu items?
Here's the menu:
Code:
<div class="Menu" id="TopMenu" runat="server">
<ul>
<li><a href="../Default.aspx" runat="server" id="HomeButton" class="ActiveMenuButton">
<span>Home</span></a></li>
[Code] ....
I need to access the InventoryButton ID, but am unable to directly.
In my masterpage, I have a menu that hosts an anchor. That anchor points to a another page and looks like this:
ASP.NET Code:
<a href="../resources/techs/masterlist.aspx">BOMs & Service Manuals</a>
I used the designer to input the href location. This page and the "masterlist" page are using the same masterpage.
When I run default.aspx and click that link, it works no problem. But when I click that link from the masterlist page, it throws an exception because it can't find the file. Which makes sense, it's looking for "/resources/resources/techs/masterlist.aspx" because that page is already within that directory. I know how to format that link you point to itself no problem, but I can't figure out how to do it so that I don't have to manually change each page, nulling the purpose of the masterpage.
I don't understand because the click event doesn't fire in ascx control nested in masterpage.
The scenario is:
In Page Pre-Init i load a particular MasterPage, one of these have a ascx control with LogOff Button.
The ascx is showed correctly but doesn't fire the button click event that allow me to logoff.
I haven't load the control programmatically but directly in masterpage:

I have 2 masterpages. (Default.master and User.master).I have a hidden field in Default.master then how can i get the hidden field value of Default.master file from User.master.is there any way to access that hidden field like: Request.form("hidID") ?
View 2 RepliesI need to know the best way to do the following. I have nested business level APIs (say level 1 & level 2). L1 needs to call L2. Both APIs use the database layer directly at their own nesting levels.
Now, in the database layer, I fetch the db connection from the pool each time as follows:
SqlConnection conn = new SqlConnection(connString);
conn.Open();
Is it proper to fetch the db connection each time on every DB level call as above? I know it will return a connection from the ASP.NET connection pool. However, wouldn't it be better to maintain the same DB connection throughout the nested calls (or throughout the current http request lifetime)? Will fetching a connection from the pool each time cause issues with nested TransactionScopes?
Is there a better, cleaner way to do this in ASP.NET 2.0?
An ASP.NET 2.0 page displays a datalist of records. Each record can have many dates, so the dates are in a nested gridview (I chose a gridview over a datalist here because we want to be able to delete a date and this is easier done in a gridview). The parent record can never be deleted.
The display works fine: the nested gridview gets its datasource during the parent datalist's OnItemDataBound event.
The problem: the nested gridview's delete function. The date gets deleted without a problem (handled in the OnRowDeleting event), but somehow the redisplay is untying all the other nested gridviews from their datasources. The delete does not appear to cause a page postback, so I don't know how the other nested gridviews are losing their datasources.
what is best to use in CTP 5 for inheritence. Ive heard of 3 ways of doing it. (This is indirectly addressed to Serenarules )
Table per Hierarchy ?
Table per Type ?
or able per Concrete Type ?
For those who wondering what the hell is that.. refer to http://weblogs.asp.net/manavi/default.aspx which is a nice blog about inheritence and polymorphism in CTP 5.
All my controllers inherit from a BaseController that has an ActionFilter attribute:
[AnalyticsData]
public class BaseController : Controller {}
public class AccountController : BaseController {}
Some of my Actions in my controllers reuse the AnalyticsData ActionFilter:
public class AccountController : BaseController
{
[AnalyticsData(Page="AccountProfile")]
public ActionResult Profile()
{
// return View
}
}
I notice that the AnalyticsData ActionFilter only runs once. This is a good thing and I only want it to run once, but I'm wondering how that happens. If I set my breakpoint inside the OnActionExecuting:
public class AnalyticsAttribute : ActionFilterAttribute
{
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
// break point set here
}
}
only gets hit once when AccountController serves it Profile view. How do ActionFilters and/or Attributes work that [AnalyticsData(Page="AccountProfile")] on the Action overrides/replaces [AnalyticsData] on BaseController?
When people talk about extending a control are they just talking about inheritance?
View 1 RepliesCan anybody tell me why multiple inheritance is not supported in C#?
View 9 RepliesI'm trying to figure out if its possible to have multiple inheritance in a view in ASP.Net MVC. Right now I'm trying to print out a list of entries from two different tables from my model in a single View. I have the following line at the top of my view:
Inherits="System.Web.Mvc.ViewPage<List<GEApproval.Models.CoursePrefix>>"
But I also want to include the table Course as follows:
Inherits="System.Web.Mvc.ViewPage<List<GEApproval.Models.Course>>"
I went ahead and created a composite class as follows:
namespace GEApproval.Models
{
public class Listings: GEApproval.Models.CoursePrefix, GEApproval.Models.ICourse
{
public List<CoursePrefix> CoursePrefixObjList { get; set; }
public List<Course> CourseObjList { get; set; }
private GEApprovalDataModel _db;
//Constructor
public Listings()
{
_db = new GEApprovalDataModel();
}
//Generate a list of all courses associated with the prefix and place in ViewData model
public void listCourses(ViewDataDictionary viewData, int prefixID)
{
var test = _db.CoursePrefix.Include("Course").First(cp => cp.id == 1);
//Show total courses for this prefix
viewData.Model = test.Course.ToList();
viewData["prefix"] = test.Prefix;
viewData["courseCount"] = test.Course.Count;
int courseCount = test.Course.Count();//Test
}
}
}
And in my view, I now have the following line:
Inherits="System.Web.Mvc.ViewPage<List<GEApproval.Models.Listings>>"
I'm still a little confused because I still cannot access the properties of the Course object when listing them in my view, because I'm only inheriting directly from CoursePrefix. I'm not sure what I'm missing. Do I need to have a constructor for the composite object? Do I need the inherit and implementation statements for CoursePrefix and ICourse respectively if I'm already, supposedly, exposing the properties of each within the Listings wrapper class?
I work in a web agency and thus we are plenty of websites from several customers. They're built upon a cms we made, so websites are quite identical for the 90% of code. However, remaining 10% struggles me and my team as it involves not only the presentation layer but behavioral logics too (ex: a website1 requires simply user/pass registration while website2 needs more data, facebook connector, etc. But this is a very easy example). Making ad hoc development for our customers is becoming painful as keep each version aligned is getting really hard for us What I really dream to have is an extendible website that works by itself, but in which I can override a part. This behavior should sound like "look for the specific part, if it doesn't exists get the base one". The parts could be a method, a class, a page, a control, a static file.
example:
Suppose I want website2 to have an own login component, let's so imagine that we have a situation like:
/website_base
|_ login.aspx
/website1
/website2
|_ login.aspx
So, if I ask for [URL] I'll get /website_base/login.aspx, but if I ask for [URL] I'll get /website2/login.aspx
I'm using EF4 to generate a model. My architecture looks like this:
IMyEntity (custom interface)
-> MyEntity - EF generated class
IMyOtherEntity (custom interface)
-> MyExtendedEntity (Customn Partial class) : MyOtherEntity (EF Generated)
The first entity has a list of MyExtendedEntity. Is there any way I can bind this with the entity framework. I'm targetting ASP.NET and WPF. The main probnlem I have is that I need an ObservableCollection in WPF, while the EF generated class only has an EntityCollection which doesn't even seem to derive from ObservableCollection.
I think I know the answer to this but hoping someone has a neat solution. We are currently using two kinds of drop down controls (telerik and .net). I'm hoping to combine these into one control but struggling with a user friendly design.
Ideally the control would be created in the design file with a bool property of say "SimpleBox", to determine which kind of control to inherit. The instantiation would then be generated in the code behind design file and the constructor would then dynamically load the base (which isn't possible). The easy solution would be for me to create a IDropDown interface then have a factory create the correct one. The only real problem with this is the fact the instantiation has to be manually written every time. Which is a hassle, and does not speed up our process at all.
Although it isn't directly possible i'm looking for a solution along the lines of a factory which is ran inside the object constructor for setting the base, based on a bool property.
Am new bee to Webservices.I have declared complete BLL in the class library.
Can call those methods defined in Class library class files(.cs file) in .asmx file.
I am currently trialing EF4 code-first. My POCO classes inherit from an Audit class that contains CreatedBy, CreatedOn, UpdatedBy, UpdatedOn. I was hoping the framework would include the Audit properties in my Action table when creating my database, however this doesn't appear to be the case. Does anyone know how to enable this without overriding the OnModelCreating() method?
Public Class Audit
Public Property CreatedOn as DateTime
End Class
Public Class Action
inherits Audit
Public Property ActionId As Int32
End Class
I have created a Entity named MediaItem which is Abstract and Game inherits form it. I create the database automatically and I get a table MediaItems and MediaItems_Game.
The issue is when I do the following in my ASP.Net Controller:
private Models.DBContainer dataModel = new DBContainer();
dataModel. ---> Intellisense shows me MediaItem but I can find no way to either navigate to or use MediaItems_Game, how can I solve this? i.e. How can I grab a list of 'Games' with some 'WHERE' constraints on another table (not pictured).
I have ASP.NET Page - PageBase and some pages that inherits this page:
public class PageBase : System.Web.Page
public class SomePage : PageBase
I would like to have some controls placed in PageBase that every page that inherits from this page (like SomePage example) will have it displayed as well. This works perfectly in WinForms. If I place control (in designer mode) to WinForm A, I will get it displayed in form B - that inherits from A. This is perfect for building complex solution and I need to extend my WinForm solution to web.How will I do it in ASP.NET?

I'm using VS2008, and I've got 10 ASP.NET 3.5 sites which all have a virtual directory which maps to one ASP.NET 3.5 subsite.
I'm trying to get a WCF service to work with client-side ajax on the subsite. I've modified my web.config file on the subsite to use baseAddressPrefixFilters, but I can't get this to work with every site. For example, I can add an entry for one site, but the ajax calls will only work for that one site. All the other sites will fail.
I'm trying to add a IsImage property that I wrote myself to the HttpPostedFile class, so that if a user is uploading a file, I can do something like this:FileUpload1.PostedFile.IsImageHow can I do that in C#?
