Using BindingNavigator & BindingSource
May 4th
One of the students in our online .NET training program wanted to know about the usage of BindingNavigator and BindingSource controls. We thought it would be useful to write an article demonstrating the usefulness of these controls. We plan to add more such articles to the articles section of our website.

Visual studio shortcuts for the .NET developer
Aug 12th
Almost every student asks me how to remember the namespaces for the classes. It’s plain simple, Visual Studio has a very useful shortcut for finding the namespace of a class. It comes in very handy when you are working on projects and you need to be fast typing code. So here are the steps to use it.
Type the name of the Class, highlight it and press Shift + Alt + F10, phew! you got your namespace.
Use the drop down displayed to do the following:
1. Add the namespace displayed to the usings clause
2. Fully qualify your class
3. Generate a new class
4. Generate a new type
The other shortcut that I find very useful is for declaring properties:
To declare a property just type prop and press TAB TAB. Now type in the datatype and a the name for the property.
There’s also a shortcut to implement interfaces automatically. This would save you tons of time in implementing interfaces.
Declare the class and type the name of the interface. Now, highlight the interface that you’d like to implement and press Shift + Alt + F10. Select the corresponding option in the dropdown – Implement interface (or) Explicitly implement interface

Retrieving Data by Using the EntityClient Provider
Jul 13th
A simple snippet that let’s you know how to retrieve data by using Entity Client Provider. You can refer to the DataModel image in the earlier post.
// Retrieving Data by Using the EntityClient Provider
// Entity Connection, Command and Parameter objects
using (EntityConnection connection =
new EntityConnection("name=EMSEntities"))
{
connection.Open();
// Note that "Order" is the actual table name
const string queryString = @"SELECT VALUE r FROM
EMSEntities.Orders as r WHERE r.OrderID=@OrderID";
EntityCommand cmd = new EntityCommand(queryString,
connection);
EntityParameter p = new EntityParameter() {
ParameterName = "OrderID", Value = 1 };
cmd.Parameters.Add(p);
EntityDataReader reader =
cmd.ExecuteReader(CommandBehavior.SequentialAccess);
while (reader.Read())
{
string orderID = reader.GetInt32(0).ToString();
string orderDate = reader.GetDateTime(1).ToString();
Debug.WriteLine(String.Format("Order ID = {0}, " +
" Order Date = {1}", orderID, orderDate));
}

Retrieving Data by using Entity SQL
Jul 13th
A simple snippet that let’s you know how to retrieve data by using Entity SQL. You can refer to the DataModel image in the previous post.
// Retrieving Data by using Entity SQL
// Note that "Orders" used in the query is an Entity
using (EMSEntities context = new EMSEntities())
{
const string queryString = @"SELECT VALUE r from " +
"Orders as r WHERE r.OrderID=@OrderID";
ObjectQuery<Order> orderQuery =
new ObjectQuery<Order>(queryString, context);
orderQuery.Parameters.Add(
new ObjectParameter("OrderID", 1));
List<Order> results = orderQuery.ToList();
string orderID = results[0].OrderID.ToString();
string orderDate = results[0].OrderDate.ToString();
Debug.WriteLine(String.Format("Order ID = {0}, " +
" Order Date = {1}", orderID, orderDate));
EntityCollection<OrderDetail> details =
results[0].OrderDetails;
Debug.WriteLine(String.Format(
"Order Detail Count = {0}", details.Count));
}

Retrieving Data by Using LINQ to Entities
Jul 13th
A simple snippet that let’s you know how to retrieve data by using LINQ to Entities. Just follow it through, I guess it’s self-explanatory.
C# .NET Entity Framework
// Retrieving Data by using LINQ to Entities
using (EMSEntities context = new EMSEntities())
{
ObjectQuery<Order> orders = context.Orders;
IQueryable<Order> query = from c in orders where
c.OrderID == 1 select c;
List<Order> results = query.ToList();
string orderID = results[0].OrderID.ToString();
string orderDate = results[0].OrderDate.ToString();
Debug.WriteLine(String.Format("Order ID = {0}, " +
" Order Date = {1}", orderID, orderDate));
EntityCollection<OrderDetail> details =
results[0].OrderDetails;
Debug.WriteLine(String.Format(
"Order Detail Count = {0}", details.Count));
}

Data Access – Entity Framework – Retrieving Complex Types
Jun 30th
Using the EDM, we created a Complex type for storing/re-using addresses. We also discussed about the advantages of complex types over Entity. Entity requires a key as opposed to complex types, which don't need a key. Given below is a sample snippet on how you can access complex types in an entity.
EMSEntities context = new EMSEntities();
var addresses = from address in context.Addresses
where address.ContactID == 1
select address;
foreach (Address address in addresses)
{
Console.WriteLine("Contact Id: " + address.ContactID);
Console.WriteLine("Contact's address1: " +
address.AddressComplex.Address1);
Console.WriteLine("Contact's address2: " +
address.AddressComplex.Address2);
}
