ASP.NET Dynamic Data is used to create data-driven web applications with minimal coding. ASP.NET Dynamic Data have the advantage of using all capabilities of the Dynamic Data Framework. You can also add specific capabilities of Dynamic Data to an existing Web application, such as:

• Web scaffolding, which is a mechanism to enhance the existing ASP.NET page Framework by dynamically display webpages based on the data model. Web scaffolding involves running a Web Application by reading the underlying database schema. Dynamic Data Scaffolding can generate a standard user interface(UI) from the data model.
• Full access to data operations (such as CREATE, DELETE, UPDATE, REMOVE and DISPLAY), relational operations, and data validation.
• Support for foreign-key relationships that allows Dynamic Data to detect the relationships among tabl ... Read more »

XSLT is very simple but powerful way to handle dynamic transform. In this example i have used XML datasource and XSLT file for generating dynamic nested menu. The menu source is an SQL server database. The script for generating SQL table is also provided with solution.

Create Excel (xls) from gridview, XSLT from XML using c#, ASP.NET or .NET

In this example i have covered 2 ways of generating XLS:

1. From Gridview
2. Using XLST file

Code for Gridview to XLS:

Code for XLS using XSLT:

Note:

• Better way is using XSLT.
• XSLT is fast resource for generating XSL
• Can be used with any datasource taking XML in between.
  

Read html, text or content between HTML tag c#. .NET

It is very easy to read content between HTML tag using c#. Steps for reading HTML content are as follows:

• Using namespace System.Xml
• Code:

        XmlDocument a=new XmlDocument();
        a.Load(Server.MapPath("~") + "//a.html");
        XmlNode n = a.SelectSingleNode("/html/body");
        TextBox1.Text = n.InnerXml;

       Note:

• Be sure about case sensitivity of tag example (/HTML/BODY) in place of (/html/body).

Their are 3 Methods for developing multi-language websites:

1. Replication
2. Generalized approach
3. Using Concept of Localization and Globalization

Replization: This is basic approach used in static websites. In this approach you need to

create replica of each web page in different languages. Suppose you have 100 web pages in

your web site and you want to provide same content in 3 languages then you have to create

300 pages for it.

This is totally incorrect approach.


Generalized approach: This approach is supported in ASP.NET version 1.1, 2.0, 3.5 and

4.0. Means this approach is supported by all version of  ASP.NET.

Localization and Globalization: This approa ... Read more »

Creating BarCode using VB.Net. or Barcode and Vb.Net.

In this project we used font which is added to font at run time. It is barcode font it convert entered text in form of Barcode value. There is file name "rmad " this must be copied into Debug folder of project so that font could be at installed run time. After generation of Barcode equivalent value and image would be created in Debug folder automatically containing Barcode value. You could download whole project as well as rmad file if need it explicitly otherwise it is already in project Debug folder.

I am using visual studio 2010. I have converted this project compatible to framework version 2.0 but still if it doesn’t work. Then just follow the steps and create your own project. This code is acceptable to all ... Read more »
