Web Forms :: Access Base Class Functions From Master Page?

May 14, 2010

I have a base class called BasePage, and a master page called SiteMaster. All my content pages inherit BasePage using BasePage instead of System.Web.UI.Page. Now, I need to access some functions in BasePage from my master page SiteMaster, let's say, the function is called "DisplayClientName()". How can I do it? Searched the Web, have found tons of similar questions but not solid solutions.

Page With Base Class With Dynamic Master Page Not Firing Events

May 3, 2010

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
}

Feb 12, 2010

I want to search my asp.net pages and user controls to see which master page and base class they use.

I have a div on my master page and I want to use it for showing page errors. I have an error display class and it works fine.

I want to counter this by having the error shown on a div within my master page.

How can I access <div id="errorSegment" runat="server">?

MVC :: Access HTTPContext And Session From Custom Base Controller Class?

Jan 13, 2010

I built a base controller class inherits from Controller class to add some custom behavior to all controllers which will inherit from this base class.

My issue is when I try to access HTTPContext and Session objects in my custom base class, they are always null.

Am I doing something wrong or need missing something?

My custom base class definition:

public class ApplicationControllerBase : Controller

controllers classes definition:

public class HomeController : ApplicationControllerBase

using ASP.NET MVC 1, .NET 3.5.

UPDATE:

It seems the issue is I try to access HTTPContext in the constructor while HTTPContext is not ready yet, I tried it in the OnActionExecuted event handler and it works fine.

My question is what is the best place to access Session object in my custom controller class, that will guarantee executing my code with all controllers.

Web Forms :: Accessing Master Page From A Base Page?

Oct 11, 2010

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.

Call Always Base Class Method Like Base.OnInit()?

Jun 29, 2010

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 ?

Web Forms :: Trying To Use A MasterType TypeName To Access A Class With Master Pages?

Sep 7, 2010

I'm trying to use a MasterType TypeName to access a class with master pages. This works when I'm using .NET 2.0, VS 2005, and C#. When I try this using .NET 3.5, VS 2008 and C# I get the error:

The type or namespace name 'classA' could not be found (are you missing a using directive or an assembly reference?) and it is pointing to the Default.aspx.designer.cs

In the default.aspx I have:

<%@ Page Language="C#" MasterPageFile="...

<%@ MasterType TypeName="classA" %>

I have added a folder App_Code to my project and in that folder I have a class file "classA.cs" that contains:

Using ...

Namespace Project.App_Code

{
public class classA : System.Web.UI.MasterPage

...

The main difference that I see from where it works and where it doesn't work is that where it doesn't work it uses the namespace called Project.So I figure my problem is in the including the class classA in the namespace or properly including the namespace and / or App_Code directory in the MasterType TypeName which I don't seem to be able to figure out.

Web Forms :: Master Pages - How To Access Content Page From Master Page

Sep 5, 2010

I have a master page setup that is used throughout my site that is basically a header with a menu. I recently added a textbox and a button to this master page which is to be a quick search box that is available anywhere in the site. When a user enters text into the search box and hits the button, I need to load the actual content page which is used to search and show search results (which also uses this same master page), and have the text entered available so the search can be triggered automatically. Again, this search text box and button is now in my master page so it could be triggered from anywhere in the app... it serves as a convenient way to do a basic search from anywhere in my app, without having to first navigate to the actual 'search page' that already exists. You can also navigate to the actual search page, which uses the same master page, where there is many more search options.I'm thrown off by the master page arrangement, which I have not used until this project. What do I do?

C# - Webservice Complex Types And Class Inheritance - Use The Properties Of The Base Class?

Mar 13, 2010

Using the following Webservice definition using aClientArgs as a complex type:

[System.Web.Script.Services.ScriptService]
public class Controller : System.Web.Services.WebService {
[WebMethod]
public void save_client(aClientArgs client)
{
// Save client data
}
}
Then defining aClientArgs as a sub-class:
public class aArgs
{
public string id = null;
public string name = null;
}
public class aClientArgs : aArgs
{
public string address = null;
public string website = null;
}
Returns the following WSDL fragment for the save_client args:
<save_client xmlns="http://tempuri.org/">
<client>
<address>string</address>
<website>string</website>
</client>
</save_client>
When I'm expecting the following:
<save_client xmlns="http://tempuri.org/">
<client>
<id>string</id>
<name>string</name>
<address>string</address>
<website>string</website>
</client>
</save_client>

So it appears that the .NET WebService is not treating inherited properties as arguments/variables for purposes of a web service. How do I get .NET to also use the properties of the base class?

Mvc - Can Set A Custom Class As The Default Base Class For Controllers In MVC3

Feb 15, 2011

I'd like to inherit all my controllers from a custom base class that I write myself. I can change the line every time I add a new controller, but it would be nicer if I could somewhere specify the default value that gets set there. That way I wouldn't need to worry about forgetting this, and other people who get added to the project later on would have an easier time.
