 In this post, I will let you know how to add or update query string parameter to current URL using Javascript.

  • function updateQueryStringParameter(uri, key, value) {  
  •       var re = new RegExp("([?&])" + key + "=.*?(&|$)", "i");  
  •       var separator = uri.indexOf('?') !== -1 ? "&" : "?";  
  •       if (uri.match(re)) {  
  •         return uri.replace(re, '$1' + key + "=" + value + '$2');  
  •       }  
  •       else {  
  •         return uri + separator + key + "=" + value;  
  •       }  
  • }  

In above example, you will need to pass three argument, first will be your current URL and second will be key which you want to add/update and last argument will be the value of key.

ADO.NET entity is an ORM (object relational mapping) which creates a higher abstract object model over ADO.NET components. So rather than getting into dataset, datatables, command, and connection objects as shown in the below code, you work on higher level domain objects like customers, suppliers, etc. DataTable table = adoDs.Tables[ 0 ]; for ( int j = 0 ; j < table.Rows.Count; j++) { DataRow row = table.Rows[j]; // Get the values of the fields string CustomerName = ( string )row[ " Customername" ]; string CustomerCode = ( string )row[ " CustomerCode" ]; }   Benefits of using EF The main and the only benefit of EF is it auto-generates code for the Model (middle layer), Data Access Layer, and mapping code, thus reducing a lot of development time.
