In ASP.NET if the code and the asp.net markup is in one ascx file for example for a user control,would it perform poorly compared to a User control with Code Behind using a cs file and a designer.cs file?
View 3 RepliesI have a project made with inline code. How can I most quickly move inline code to codebehind for each webform? First, how can I add a codebehind page aspx.c or aspx.vb to one that doesn't have one?
View 3 RepliesI have a project that suddenly the webusercontrols starting to ignore the codeBehind files.
When ever I click a button it setups a inline button click event in the ascx file

Why does my VS2008 suddenly start to use inline click event instead of using the codebehind ascx.cs file that I want?
Are there any differences between coding row-specific stuff inline within the repeater's template and doing so in the codebehind file in ItemDataBound?
EDIT: Re: differences - I think we're all agreed it makes for markup that's nasty to read/maintain :) I was thinking of performance benefits.
I am generating a dropdown list in codebehind and cannot get the selectedindexchanged event to fire automatically. It works fine when put directly into the ASPX page, but I need it to be in the codebehind.
This doesn't work -

I know placing all your styles in a CSS file is the best thing to do as it is a lot neater.
But does it REALLY matter if the styles are inline or in a CSS?
Edit below
My plan is to just place the styles in my MasterPage and all other pages will use the MasterPage....I believe the correct term is not "INLINE" but Embedded?

View 1 RepliesI've gone rounds with this ever since I started programming classic ASP 12 (or so) years ago and I've never found a great solution because the architecture of ASP and ASP.NET has always been a swamp of bad practices, magic shared singletons, etc. My biggest issue is with the HttpApplication object with its non-event events (Application_Start, Application_End, etc.).
If you want to do stuff once for the entire lifespan of an HTTP application, Application_Start is the obvious place to do it. Right? Not exactly. Firstly, this is not an event per se, it's a magic naming convention that, when followed, causes the method to be called once per AppDomain created by IIS.
Besides magic naming conventions being a horrible practice, I've started to think it might be a reason there exist no such thing as a Start event on the HttpApplication object. So I've experimented with events that do exist, such as Init. Well, this isn't really an event either, it's an overridable method, which is the next best thing.
It seems that the Init() method is called for every instantiation of an HttpApplication object, which happens a lot more than once per AppDomain. This means that I might as just put my startup logic inside the HttpApplication object's constructor.
Now my question is, why shouldn't I put my startup logic in the constructor? Why does even Init() exist and do I need to care about Application_Start? If I do, can anyone explain why there is no proper event or overridable method for this pseudo-event in the HttpApplication object?
And can anyone explain to me why in a typical ASP.NET application, 8 instances of my HttpApplication are created (which causes the constructor and Init to run just as many times, of course; this can be mitigated with locking and a shared static boolean called initialized) when my application only has a single AppDomain?
As the title says then the question is relative simple however I cant decide whether a resource file with strings in is better than hard-coded strings...

The inline code
<% for (int i = 0; i < ThumbnailList.Items.Count; i++)
{ Response.Write("thumbnailViews[" + i.ToString() + "] = $find('" +
ThumbnailList.Items[i].FindControl("ThumbnailView").ClientID + "');
"); } %>
produces a bunch of compile time errors in Visual Studio 2008 - although it works fine.
But this seems to be the exact way inline code should be added, at least according to this MS help file:

The errors are:
expected expression (at "<%")
expected ';' (at "int i")
expected ')' (at ThumbnailList.Items.Count;

my ASP.NET application reads an xml file to determine which environment it's currently in (e.g. local, development, production).
It checks this file every single time it opens a connection to the database, in order to know which connection string to grab from the Application Settings.
I'm entering a phase of development where efficiency is becoming a concern. I don't think it's a good idea to have to read a file on a physical disk ever single time I wish to access the database (very often).
I was considering storing the connection string in Application["ConnectionString"].
[code].....
I didn't design the application so I figure there must have been a reason for reading the xml file every time (to change settings while the application runs?) I have very little concept of the inner workings here. What are the pros and cons?
I wanted to know how can I get request to XML file (.xml) but to render the response using codebehind.(like doing <% ... %> )
View 2 RepliesHow can I achieve the desired effect?
Here's the code:
<% if(!String.IsNullOrEmpty(%><%#Eval(Container.DataItem,"OrderXml");%><%)){ %>
etc., which is placed inside of an ItemTemplate inside of a TemplateColumn. In the CodeBehind page I will bind a value to the OrderXml field, which occasionally is NULL.
Unfortunately I get compilation errors.
