C# - Where Is The Component Initialize Method In 3.5
Jan 10, 2010
I want to create my own naming convention for page events rather than AutoEventWireUp but I couldn't find Component Initialize methods any where ? Should I override it ? But in which class it is defined ?
Edit :
For example : I don't want to use Page_Load but LoadThisPage naming. So It should be like
Load += new LoadThisPage(sender,e);
I was expecting a InitializeComponent method where I can initialize page,controls etc. events handlers...But it turned out to be Constructor function :
So what confused me is I thought there should have been a method like InitializeComponent which does things for me already created by Designer itself so I thought I could define my own event handler names within this method by overriding it in the say Default.aspx.cs .

I have a site that uses ActiveRecord. I'm getting an exception that says "An ActiveRecord class () was used but the framework seems not properly initialized. Did you forget about ActiveRecordStarter.Initialize() ?" This is a web application, and the Initialize() method is called by the Application_Start event handler.
I created a new page that also calls the initialize() method. If I visit that page once, then the rest of the site works. If I visit it a second time, I get an exception stating that the Initialize() method can only be called once.
I've tried modifying the web.config and resetting the application pool to force Application_Start to run.
This only happens in production; dev, my stage, and client stage are fine. Production is the only load-balanced environment--I'm not sure if that comes into play.
Edit: We have another site deployed in the same environment which successfully uses ActiveRecord with the same initialization code. One difference is that the site that is working has only the ActiveRecord code in Application_Start; the site that doesn't also sets up some URL routing in Application_Start.

I'm overriding the Controller.Initialize method to set some stuff before each ActionResult is executed, however I'm finding that the method is being called multiple times for each request (anywhere between 2 - 10 times). I'm running in Cassini.
My hunch is that it is running for all static files (images, css etc) as well as the requested action - although I may be wrong? I thought maybe something was wrong in my web.config but it all looks right to me.

I am trying to stop the data flow when certain conditions happen in the script component. Like if a row in the data set has an invalid date, I dont want that dataset to be inserted in the tables or go through OLEDB Destination, rather I want the entire data flow for that dataset to stop and go back to the control flow page.
I have tried mulitple solutions but nothing worked. Conditional Split ends up inserting the correct rows, but I just dont want anyting to be inserted when one row is bad, where as I do want the entire dataset to be inserted if all rows are good.
How can I fail the component when certain conditions happen int eh script component.

I have - for instance - an asp:FormView which supports Read, Insert, Update, Delete and is bound to a DataSource:
[code]....
If I am in Read-Mode or Edit-Mode the control is initialized with the property MyText of the current object which is bound to the FormView.
But when I go to Insert-Mode I do not have a "current object" (FormView1.DataItem is indeed null) and the controls are empty.
If I want to have my TextBox control initialized with a specific value how can I do that? In which event can I hook in to set default values to the controls in the InsertItemTemplate?
Especially I have in mind using an ObjectDataSource. I was expecting that the InsertItemTemplate is initialized with a business object which underlies my ObjectDataSource and which is created by the ASP.NET framework simply by using its default constructor when the InsertItemTemplate gets activated. In the default constructor I would init the class members to the default values I'd like to have in my controls of the InsertItemTemplate. But unfortunately that's not the case: No "default" object is created and bound to the FormView. So it seems I have to initialize all controls separately or to create the default object manually and bind it to the InsertItemTemplate of the FormView. But how and where can I do that?

I was looking for a custom membership/role provider and came across The Altairis Web Security Toolkit Looked at the source and this is just perfect for what I had in mind. So I implemented it in my project, created a database and tables and configured it in my web.config. Everything compiles fine, but seems I'm being stupid in how to actually use it. (Looking at the source code here might be useful in helping me out) Just to see it work, I'm making a call like this:
Code:
private readonly KrokSqlMembershipProvider_membershipService;
_membershipService = new KrokSqlMembershipProvider();
MembershipCreateStatus status;
_membershipService.CreateUser("krok", "password", "[URL], "", "", true, null, out status);
However when I debug the code, I realize that in the MembershipProvider class the configuration settings to be loaded from the web.config are empty, so it fail when trying to connect to my database (empty connection string). I notice the settings are retrieved in the Initialize method, but I'm not sure if I'm suppose to call that, and if so, how. (The sample application that comes with the source code have no code in it. It's asp.net, while I'm using asp.net mvc)

I'm having a hard time with the page cycles when using masterpages and contentpages. My masterpage has two linkbuttons that are used to select a language (using resources). When these buttons are clicked I create Session["language"]. The goal I have is to 'translate' my masterpage after the buttons are clicked AND to translate the content page.I've been trying all kinds of different methods (Page_Load etc) based on this url: http://msdn.microsoft.com/en-us/library/dct97kc3.aspx but it never works like it should. Usually the content page only gets translated after two clicks. I can't figure out the cycle problem between the masterpage and the content page combined with the click-events.

I am using a Telerik combobox and using jquery to make a clone of it.
the control is being rendered correctly, however the dropdown is not working I believe due to the fact the javascript has not been initialized on the control.
Is there a way to do this or a better way to make a duplicate of the control?
I may have to resort to making an ajax request but would ideally like to keep it all clientside.

How can I write the C# code (aspx) to initialize the user control with some default property values? I mean where/which event? I have a user control with a gridview that I bind on container page. On page load of the container page I bind the data. I tried writing the initialization code in initproperties but it didn't work. Please suggest where can I set the default values for my usercontrol?
Edited:As suggested by DOK.. I already have a property and I change width of one of the DIVs. Here is the code that is not working.
public int CollapsiblePanelWidth
{
set[code]....
this works only if I set the width on calling program. Otherwise the default value of style="width: 105px;" is not added.

I designed a user control. It contains a public property "CurrentValue". When I try to initialize the property using an Eval expression, a null value is assigned.
// In below code, label assignment is OK, RatingNull user control assignment get null
<asp:TemplateField>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Eval("Difficulty") %>'
<uc1:RatingNull ID="RatingNull1" runat="server" CurrentValue='<%# Eval("Difficulty") %>' />
</ItemTemplate>
If I directly assigned a value (ie, CurrentValue="5"), user control works fine.
public partial class RatingNull : System.Web.UI.UserControl
{
private string _CurrentValue;
public string CurrentValue
{
get { return _CurrentValue; }
set { _CurrentValue = value; }
}
