1. Describe the role of inetinfo.exe, aspnet_isapi.dll andaspnet_wp.exe in the
page loading process. inetinfo.exe is theMicrosoft IIS server running, handling
ASP.NET requests among other things.When an ASP.NET request is received
(usually a file with .aspx extension),the ISAPI filter aspnet_isapi.dll takes care
of it by passing the request tothe actual worker process aspnet_wp.exe.
2. What’s the difference between Response.Write()
andResponse.Output.Write()? The latter one allows you to write
formattedoutput.
3. What methods are fired during the page load? Init() - when the pageis
instantiated, Load() - when the page is loaded into server memory,PreRender() -
the brief moment before the page is displayed to the user asHTML, Unload() -
when page finishes loading.
4. Where does the Web page belong in the .NET Framework class
hierarchy?System.Web.UI.Page
5. Where do you store the information about the user’s locale?
System.Web.UI.Page.Culture
6. What’s the difference between Codebehind="MyCode.aspx.cs"
andSrc="MyCode.aspx.cs"? CodeBehind is relevant to Visual Studio.NET
only.
7. What’s a bubbled event? When you have a complex control, like DataGrid,
writing an event processing routine for each object (cell, button, row, etc.) is
quite tedious. The controls can bubble up their eventhandlers, allowing the main
DataGrid event handler to take care of its constituents.
8. Suppose you want a certain ASP.NET function executed on MouseOver
overa certain button. Where do you add an event handler? It’s the
Attributesproperty, the Add function inside that property. So
btnSubmit.Attributes.Add("onMouseOver","someClientCod
e();")
9. What data type does the RangeValidator control support? Integer,String and
Date.

10. Explain the differences between Server-side and Client-side code? Serverside
code runs on the server. Client-side code runs in the clients’ browser.
11. What type of code (server or client) is found in a Code-Behind class?
Server-side code.
12. Should validation (did the user enter a real date) occur server-side or
client-side? Why? Client-side. This reduces an additional request to the server
to validate the users input.
13. What does the "EnableViewState" property do? Why would I want it on or
off? It enables the viewstate on the page. It allows the page to save the users
input on a form.
14. What is the difference between Server.Transfer and Response.Redirect?
Why would I choose one over the other? Server.Transfer is used to post a
form to another page. Response.Redirect is used to redirect the user to another
page or site.
15. Can you explain the difference between an ADO.NET Dataset and an ADO
Recordset?
· A DataSet can represent an entire relational database in memory,
complete with tables, relations, and views.
· A DataSet is designed to work without any continuing connection to
the original data source.
· Data in a DataSet is bulk-loaded, rather than being loaded on
demand.
· There's no concept of cursor types in a DataSet.
· DataSets have no current record pointer You can use For Each
loops to move through the data.
· You can store many edits in a DataSet, and write them to the
original data source in a single operation.
· Though the DataSet is universal, other objects in ADO.NET come in
different versions for different data sources.
16. Can you give an example of what might be best suited to place in the
Application_Start and Session_Start subroutines? This is where you can set
the specific variables for the Application and Session objects.
17. If I’m developing an application that must accommodate multiple security
levels though secure login and my ASP.NET web application is spanned
across three web-servers (using round-robin load balancing) what would be
the best approach to maintain login-in state for the users? Maintain the login
state security through a database.
18. Can you explain what inheritance is and an example of when you might use
it? When you want to inherit (use the functionality of) another class. Base Class
Employee. A Manager class could be derived from the Employee base class.
19. Whats an assembly? Assemblies are the building blocks of the .NET
framework. Overview of assemblies from MSDN
20. Describe the difference between inline and code behind. Inline code written
along side the html in a page. Code-behind is code written in a separate file and
referenced by the .aspx page.
