I have the below structure. Admin_note --> AdminBasePage --> System.Web.UI.Page.But Page_Load does not call in AdminBasePage when calling page_load in Admin_note class.Do you know how to solve??

I'm using a simple base class for my controller that sets a piece of ViewData and makes use of the HttpContext. My understanding is that I need to put this code in Initialize() or OnActionExecuting(). I tried both, but believe Initialize() is what I want.
This works when running the app in VS just fine.
I wrote a unit test that calls the action and checks the ViewData for the expected value. When unit testing, neither method is called.
I have a class BasePage this class inhereted from System.Web.UI.Page, all my other pages inhereted from BasePage.
How i can access Master page in BasePage ? To access master page at any page i use :
Template masterPage = Master as Template; where Template class of my Master page.
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.
View 2 RepliesI just discover why some validation is working bad on some of my forms: the button click event is being called before page load.
What I need for good is (I consider this is a normal cycle of events):
The user press a buttonSome validation occurs at client side (js function returns true if success)Some validation occurs at server sideThe page loads again showing the results
But this is what I get (BAD):
The user press a buttonSome validation occurs at client side (js function returns true if success)The page loads showing no results, because server validation hasnt happened yet Some validation occurs at server sideThe page doesn´t loads again and I cant see the results, so my client cant know what happened on the server side
This is how I tried to implement this:

View 2 RepliesI am attempting to access a textbox control on a master page from a code behind base class but having problems. I have 3 levels of master pages. m1.master is the master page for m2.master which is the master page for m3.master.m3.master has a textbox as shown below

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 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 the following PerformanceFactsheet.aspx.cs page class
public partial class PerformanceFactsheet : FactsheetBase
protected void Page_Load(object sender, EventArgs e)
// do stuff with the data extracted in FactsheetBase
divPerformance.Controls.Add(this.Data);
where FactsheetBase is defined as
public class FactsheetBase : System.Web.UI.Page
[code]...
I've got a page Default.aspx, it was inherited from class MyBasePage
like this
public partial class _Default : MyBasePage, ICallbackEventHandler
{
}
also it has a master page
<%@ Page Language="C#" AutoEventWireup="true" EnableEventValidation="false" MasterPageFile="~/Master/MyMaster.master" CodeFile="Default.aspx.cs" Inherits="_Default" %>
this master page also has a master
<%@ Master Language="C#" MasterPageFile="~/Master/Base.master" AutoEventWireup="true" CodeFile="MyMaster.cs" Inherits="MyMaster" %>
All works ok, but then i discovered that
Page_Load in Default.aspx is called two times, and both from method OnLoad in MyBasePage
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
}
base.OnLoad(e) calls Page_Load.
I've got a site with such a structure of master pages and basepage, but it works ok, method page_load is called only once.
So why would in the second site PAge_Load be called twice?
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.
it's possible to put the database connection settings into a base page class so that I can auto-init them on a page. like this document: [URL] but with instructions in VB.net
View 1 RepliesI 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?
View 3 RepliesI want to search my asp.net pages and user controls to see which master page and base class they use. I mention search because we are re-factoring a large project and we need to track progress on the code conversion. I know I can pull this information individually but I need a automated and repeatable procedure.
View 1 RepliesCurrently I'm doing common functionality required throughout my site inside of my masterpage. What I want to do is move this functionality to a BaseClass so All my pages inherit from the Base Class. However, I'm not sure how to set this up interms of c# code with regards to Using a Base Class and then having a masterpage applied to my aspx pages that i create.

View 2 RepliesUsing 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>

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?
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.
View 3 RepliesIn 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.
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 am trying to export data to a csv file in my web application.
I have the following class to enable this but i want to know how to call the class on Page_Load?

{
string attachment = "attachment; filename=PersonList.csv";

I want to add a custom base class for all of my web forms. I created a "App_code" folder in my asp.net web project and add a simple base page class like this:
namespace MySite.Web
{
// base page for all the pages that need localization
public class LocalizationPage : System.Web.UI.Page
{
protected override void InitializeCulture()
{
base.InitializeCulture();
}
}
}
And then I try to let asp.net web form to inherit from this base page. I have something like this:
using MySite.Web;
namespace MySite.Public
{
public partial class RegisterPage : LocalizationPage
{
}
}
Now I run into problem where Visual Studio doesn't recognize the LocalizationPage class I created. On the above code snippet, LocalizationPage is not highlighted as a class. And when I try to compile, I got the following error message:
Error 1 The type or namespace name 'LocalizationPage' could not be found (are you missing a using directive or an assembly reference?)
We have a base class that all our webpages in our application inherit from. I have a static method in the base class which when called will clear values from the application cache. Now the issue is this method needs to be triggered from a source outside the current application. I there any way this can be accomplished without creating an aspx page that will call this base method on page load.
