ASP.NET Interview Questions related to Master Pages, ASP.Net Page Life Cycle, Ajax, Jquery, Json, Web Service

1. How to change master page of a content page dynamically?
   
2. Why to change Masterpage of a page in Page_PreInit() function ?
   
3. What is the maximum limit of parameters we can pass to a stored procedure ?
   
4. How can we change current theme of a page at Page_PreInit() from master page?

ASP.NET Ajax Extension Script Manager

In order to use ASP.NET AJAX you need to add ScriptManager to your webpage. This control is the brain of ASP.NET AJAX.

You can add it from ToolBox tabnamed AJAX Extensions. The source of this control is as below:

< asp:ScriptManager ID="ScriptManager1" runat="server" >< / asp:ScriptManager >

This control add links to ASP.NET AJAX libraries in your page. The output of this looks something like:

< Script src="/YourWebSite/ScriptResource.axd?d=RUSU1mI......" type="text/javascript" >< /Script >

It brings the JavaScript code using 'src' attribute. Rather than adding extra javascript files, the src attribute points to ScriptResource.axd. ScriptResource.axd is not an actual file. It tells ASP.NET to find Javascript file in one of the compiled .Net assemblies. The query string arguments tells ScriptResource.axd extension the file to be sent to the browser.

Every page that uses ASP.NET AJAX requires an instance of the ScriptManager. However, you can only use one ScriptManager on a page. ASP.NET AJAX-enabled controls can interact with the ScriptManager, directing it to link to additional Javascript files.

It's recommended that you add ScriptManager to master pages of the website. However, different content pages may require different settings of the properties of ScriptManager. The solution to this requirement is to add ScriptManager to master page and then add ScriptManagerProxy to the content pages. This ScriptManagerProxy can be configured in the same way as ScriptManager on the page.


The Javascript files used by ASP.NET AJAX contains thousands of complex lines that forms the bases of all Ajax functionalities. These files are ver compant not more than 200 KB, depending on the features being used on the page. This code is downloaded only once and then cached by the browser for later use. Also ASP.NET sends a compressed version of script in case the browser supports it. Thus Ajax enabled web pages do not require a longer download time.

Gmail, Yahoo, Hotmail Attachment Size Limit

Email Attachment Size Limit

Email service has provided us a great advantage over our traditional communication services. But almost all the email service providers have imposed some limitations and restrictions like gmail, yahoo and hotmail as the well known mail server.


We must understand the maximum size of an attachment before sending an email attachment.

Gmail Attachment Size: 20MB
Yahoo Attachment Size: 20MB
Hotmail Attachment Size: 10MB

And even then if you want to send a larger file as required sometime you can use some other alternatives. For example using yousendit.com you can send upto 2GB of file.

ASP.Net Restricted File Types

ASP.Net Hidden File Type Restricted File Types

ASP.Net stops you from requesting certain file types and authomatically provides a certain level of security to your configuration and source code files. This is accomplished by registering the file types with IIS and are assigned to HttpForbidderHandler class. This class has the role to simply deny all the requests it receives.

Thus ASP.Net blocks access to Visual Studio project files, Source Code files and some other resources like:

.cs file (C# files)
.vb file (VB.Net files)
.config file (configuration files like web.config file)
.ascx file (ASP.Net user controls)
.vbproj file (VB.Net project file)
.csproj file (C# Project file)
.asax file (Global.asax file containing global.asax events)
.resx file (resource file format consisting of XML entries)
.resources file (specifically designed to create .resources files)



For further details your can refer to web.config.default file in

c:\Windows\Microsoft.NET\Framework\v2.0.50727\Config folder

and find the text

System.Web.HttpForbiddenHandler
