ViewState Control in ASP.NET 4.0

CodeProject
View State is one of the most important and useful client side state management mechanisms. It can store the page value at the time of post back (Sending and Receiving information from Server) of your page. ASP.NET pages provide the View State property as a built-in structure for automatically storing values between multiple requests for the same page.

we generally used “EnableViewState” Properties for both Page Level and Server Control Level to maintain the view state. Till ASP.NET 3.5 Version, Page Level view state control treat as highest priorities. Which means If we set EnableViewState= “False” in page level that will automatically derived by all the server side control. In that case if we set “EnableViewState=”True”” for any server side control will treat as false, as we have defined them “False” in Page Level.Here is one complete article on ASP.NET 2.0/3.5 View State , which may helpful for you

Now, let’s have a look into the changes in ViewState Control in ASP.NET 4.0. There is a massive change in View State Control in ASP.NET 4.0 which is very much helpful for developer also. Asp.net 4.0 added a new property to Page object and server controls called ViewStateMode.

Mastering in Visual Studio 2010 Debugging

Visual Studio IDE gives us a lot of tools to debug our application. Sometimes debugging activity takes a very long time to identify the root cause. But VS IDE provides a lot of handy tools which help to debug code in a better way. Debugger features include error listing, adding breakpoints, visualize the program flow, control the flow of execution, data tips, watch variables and many more. Many of them are very common for many developers and many are not. In this article, I have discussed all the important features of VS IDE for debugging like Breakpoint, labeling and saving breakpoints, putting conditions and filter on breakpoints, DataTips, Watch windows, Multithreaded debugging, Thread window, overview of parallel debugging and overview of IntelliTrace Debugging

Using Bookmark in Visual Studio

CodeProject

Introduction

As name suggests, bookmarking speedup your code navigation in visual studio. There may be some portion of code where we need to move very frequently. Generally we scroll the page and move to that section, but Visual studio provides great features by which we can move to a particular section very quickly using some shortcut keys. This is called Bookmarking of Code.
Below are the set of Icons which are used to navigate the code using Bookmark.

How To Use

We can place the bookmark by clicking on Bookmark icon or using keys Ctrl + K, Ctrl + K. Below is the sample code where I have putted two bookmarks in different section of code.



Now we can easily navigate among those breakpoint using Ctrl + K, Ctrl + N for Next Bookmark and Ctrl + K , Ctrl + p for Previous mark. We can achieve the same using following toolbar icon.



This is very much easy to use and its give you very fast navigation throughout the code.

Using Bookmark Window:

Visual Studio provides you Bookmark window where you can get list of all bookmarked section.



Now, by selecting particular bookmark from the Bookmarks list we can easily move to the particular section.

Renaming BookMarks

For easy reference we can also rename bookmark so that we can easily identify them. This helps us to easily move to particular code block based on the name given.  This is useful when we are having many bookmarks in the bookmark list.



As I have renamed my bookmark list as below

Summary

This may not be new to many of us, but it may helpful for some beginners.  Using this features we can navingate our code very easily. Please provide your valuable suggestion and feedback.

XSL Transformation : Rendering XML using XSL - HTML Output

Overview

Some times we need to display the XML data in our web application in specific format. XSLT provides the ability to display the XML document in some specific format like HTML, PDF etc. We can select a a XML file or a portion of XML File and using XSL Transformation we can display in some specific format.



An XSL transformation need an XML document to transform and an XSL style sheet describing how the transformation will take place. An XSLT engine then transforms the XML document via the XSL style sheet and will produce the output in the format specified by the style sheet.

Here I am just going to show you how we can display a XML data using XSL in our web page and which will help beginners to start with. This is an sample application. The XSL, which I have used over here is very simple. If you want to learn details on XSL please read tutorials from W3School.

 

 

How to Implement ?

1. Create Data Base :

Rather than reading the data from xml, I have read the data from database. First of all I have create an DB Student with table name "StudentDetails" . Table contain some dummy data like,

2. Add XSL File

Before, reading the data from database, we have to create the XSL file, We can add XSL file by just right click on the project > Add New Item >Select XSLT File

I have put the xsl file in a specific folder called XSL .

 

 

 

 

3. Desing XSL

Now, Designing XSL is one of the important task, and there are many things that related with XSL . In my case, this is very simple XSL, but if you need to learn in details, I will suggest you to read from W3School. First of all have a look into the XML data which I have got from the dataset.



And based on that we need to desing the XSL File. Below is the StudentDetails XSL

 

 

[sourcecode language='xml']



style="background-color:#123456;font-family:verdana;font-size:10pt;border:1">

Roll

Name

Address

style="font-family:verdana;font-size:10pt;border:1">










[/sourcecode]

Now, have a look into the code,

Read the data from database and put it into dataset. We can easily get the XML from dataset using.

[sourcecode language='csharp']

string XMLString=ds.GetXml();

[/sourcecode]

Below code is used to read data from database

[sourcecode language='csharp']
public string strstudentDetails = string.Empty;
protected void Page_Load(object sender, EventArgs e)
{
string _strConnectionString = "Data Source=.\\sqlexpress;Initial Catalog=Student;Integrated Security=True";
string _strquery = "select * from studentDetails";
SqlConnection con = new SqlConnection(_strConnectionString);
DataSet ds = new DataSet("Students");
SqlDataAdapter da = new SqlDataAdapter(_strquery, con);
da.Fill(ds);
//Get the XML From DataSet
string strXML = ds.GetXml();
strstudentDetails=GetHtml(Server.MapPath("~/xsl/studentDetails.xsl"), strXML);
}
[/sourcecode]

GetHtml function actually doing the job. Its taking XSL Stylesheet and XML data as parameter and returning the html output

 

 

 

 

[sourcecode language='csharp']
///

/// Get HTML From XML and XSL
///

///
XSL File Path
///
XML String
/// HTML Output
public static string GetHtml(string xsltPath, string xml)
{
MemoryStream stream = new MemoryStream(ASCIIEncoding.Default.GetBytes(xml));
XPathDocument document = new XPathDocument(stream);
StringWriter writer = new StringWriter();
XslCompiledTransform transform = new XslCompiledTransform();
transform.Load(xsltPath);
transform.Transform(document, null, writer);
return writer.ToString();
}
}
[/sourcecode]

Now for displaying the result, we have to put following line in the aspx page,

[sourcecode language='html']

Student Info : Displying using XSL Rendering

<%= strstudentDetails %>

[/sourcecode]

and the output like,



Hope this will help you to move ahead with XSL Transformation.

Thankyou
