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.

Response.Output.Write() allows you to write formatted output.

Init() - when the page is instantiated
Load() - when the page is loaded into server memory
PreRender() - the brief moment before the page is displayed to the user as HTML
Unload() - when page finishes loading.

After the Init() and before the Page_Load(), or OnLoad() for a control.

CodeBehind is relevant to Visual Studio.NET only.

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.

Add an OnMouseOver attribute to the button.Example: btnSubmit.Attributes.Add("onmouseover","someClientCodeHere();");

Integer, String, and Date.

Server-side code executes on the server.Client-side code executes in the client's browser.

The answer is server-side code since code-behind is executed on the server.However,
during the code-behind's execution on the server, it can render client-side code such
as JavaScript to be processed in the clients browser.But just to be clear, code-behind
executes on the server, thus making it server-side code.

All user input data validation should occur on the server at a minimum.Additionally,
client-side validation can be performed where deemed appropriate and feasable to
provide a richer, more responsive experience for the user.

Server.Transfer transfers page processing from one page directly to the next page
without making a round-trip back to the client's browser.This provides a faster
response with a little less overhead on the server.Server.Transfer does not update the
clients url history list or current url.Response.Redirect is used to redirect the user's
browser to another page or site.This performas a trip back to the client where the
client's browser is redirected to the new page.The user's browser history list is
updated to reflect the new address.

Valid answers are:
·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.

The Global.asax (including the Global.asax.cs file) is used to implement application and session level events.

This is where you can set the specific variables for the Application and Session objects.

When you want to inherit (use the functionality of) another class.Example: With a base class named Employee, a Manager class could be derived from the Employee base class.

Assemblies are the building blocks of the .NET framework. Overview of assemblies from MSDN

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.

The DiffGram is one of the two XML formats that you can use to render DataSet object
contents to XML.A good use is reading database data to an XML file to be sent to a
Web Service.

MSIL is the Microsoft Intermediate Language. All .NET compatible languages will get
converted to MSIL.MSIL also allows the .NET Framework to JIT compile the assembly
on the installed computer.

The Fill() method.

No, it just reads the information from its data source.

ItemTemplate.

Use the AlternatingItemTemplate.

You must set the DataSource property and call the DataBind method.

The Page class.

ControlToValidate property and Text property.
