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.
What’s the difference between Response.Write()
andResponse.Output.Write()?
The latter one allows you to write formattedoutput.
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.
Where does the Web page belong in the .NET Framework
class hierarchy?System.Web.UI.Page
Where do you store the information about the user’s
locale? System.Web.UI.Page.Culture
What’s the difference between Codebehind="MyCode.aspx.cs"
andSrc="MyCode.aspx.cs"?
CodeBehind is relevant to Visual Studio.NET only.
What’s a bubbled event? When you have a complex control,
likeDataGrid,
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
itsconstituents.
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","someClientCode();")A
simple”Javascript:ClientCode();” in the button control
of the .aspx
page will attach the handler (javascript function)to the
onmouseover event.
What data type does the RangeValidator control support?
Integer,String
and Date.
Where would you use an iHTTPModule, and what are the
limitations of any
approach you might take in implementing one? One of
ASP.NET’s most useful
features is the extensibility
of the HTTP pipeline, the path that data takes between
client and server.
You can use them to extend your ASP.NET applications by
adding pre- and post-processing
to each HTTP request coming into your application. For
example, if you wanted
custom authentication facilities for your application,
the best technique
would be to intercept the request when it comes in and
process the request
in a custom HTTP module.
Explain what a diffgram is, and a good use for one? A
DiffGram is
an XML format that is used to identify current and
original versions of data
elements. The DataSet uses the DiffGram format to load
and persist its contents,
and to serialize its contents for transport across a
network connection. When
a DataSet is written as a DiffGram, it populates the
DiffGram with all the
necessary information to accurately recreate the
contents, though not the
schema, of the DataSet, including column values from
both the Original and
Current row versions, row error information, and row
order. |
