DbDataSource

DbDataSource is a handy component that was designed to provide advanced PC users such as software developers or programmers with an ASP.NET WebForms DataSource control to be utilized alongside the EntityFramework CodeFirst.

With DbDataSource, users will be able to quickly and easily add a datasource in their markup. Moreover, it also provides them with the ability to rapidly filter the results with LINQ within the Where property as well as select values using the Select property in a specific manner.

A data source can be added in the user's markup as displayed in the following example: "ss:DbDataSource ID="source" runat="server" Source="Namespace.MyDbContext.MyDbSetProperty"".

It is also possible for developers to filter their results with LINQ in the Where property and even select values by using the Select property. An example of this situation: "Where:

<% source.Where = set => set.OfType<MyEntityType>().Where(s => My where expression here)) %>

Select:

<% source.Select = set => set.OfType<MyEntityType>().Select(s => My select expression here)) %> ".

It is worth noting that if the Select property is set, it will become impossible to insert, update or delete any more data from the datasource that has been previously loaded.
