Features
Cross Platform Support
ComponentOne Studio
for Entity Framework includes the C1DataSource component, which
allows you to combine multiple client view sources using Entity
Framework or RIA Services. C1DataSource is supported in Silverlight
4, WPF, and WinForms (.NET 4.0).
Smart Client-side Caching
The key to most of
Studio for Entity Framework’s features is its built-in client-side
data cache. Studio for Entity Framework maintains a cache of
entities on the client. When new queries are executed, it does not
necessarily go to the server. It checks the client-side cache first
and will not go to the server if it can find the result in the
cache. By minimising the number of trips to and from the server,
this significantly improves performance and speed.
Context Management
With Studio for Entity
Framework you can use a single data context for your entire
application. This allows you to forget the troubles of programming
against multiple contexts across multiple views. Without Studio for
Entity Framework you might have multiple contexts which can be very
difficult to write code when you need to use entities from different
contexts together. This feature is made possible by the smart
client-side cache.
Memory Management
Studio for Entity Framework
is optimised for both performance and memory consumption. It manages
memory resources for you releasing old entity objects in the cache
when necessary to prevent memory leaks. In doing so, it fully
preserves consistency by maintaining required entities and entities
modified by the user.
Virtual Mode for Large DataSets
Handle
infinitely large data sets. Virtual Mode technology allows you to
navigate through large data sets asynchronously. It works like
paging on the data layer, but the user can scroll through the data
as if all rows were on the client. As the user scrolls, chunks of
data are retrieved from the source page by page and disposed of as
necessary. You can use Virtual Mode with various UI controls such as
the standard DataGrid or C1FlexGrid. Data can also be modified. This
feature is transparent to the developer; you can turn on Virtual
Mode with one simple property setting.
Paging with Data Modification
For
applications that prefer a paging interface, Studio for Entity
Framework also supports paging without any limitations on data
modification. That means users can make changes on multiple pages in
one session before having to push the changes back to the database.
This is a substantial improvement over other paging implementations
such as with the Microsoft RIA Services DomainDataSource. Paging
with C1DataSource is also supported in WinForms and WPF where paging
is not already provided.
Automatic Look-up Columns
C1DataSource can
automatically configure grid columns to display look-up comboboxes
for referenced class objects. Without C1DataSource, columns display
useless class types rather than readable information, and tedious
work is involved to fix the problem. This time-saving feature can be
turned on with one Boolean property.
Server-side Filtering
Data brought from the
server to the client usually needs to be filtered, or restricted in
some way, to avoid moving large amounts of data over the wire and
heaping it on the client. Studio for Entity Framework makes this
common task very simple. Instead of doing it manually in code, you
can specify server-side filters as simple property settings on
C1DataSource.
Saving Modified Data
Studio for Entity
Framework’s smart client caching makes it easy to write code that
saves modified data back to the server. With just one line of code
and one trip to the server, you can save multiple entities. Data
Studio does all of the heavy lifting; it maintains changed entities
in the cache, and ensures the cache is always consistent, while also
optimising memory usage and performance.
Client-side Transactions
Studio for Entity
Framework gives developers a simple and powerful mechanism for
rolling back (canceling) and accepting changes on the client without
involving the server. It makes it easy to implement Cancel/Undo and
OK/Accept buttons anywhere, even in nested (child) dialogs and
forms, modal and modeless.
Live Views with LiveLinq
LINQ is the perfect
tool for transforming raw data into custom views. Studio for Entity
Framework makes LINQ even more powerful by making LINQ query
statements live. Studio for Entity Framework includes ComponentOne
LiveLinq, an extension library which augments the functionality of
LINQ to speed up queries and provide live views. With LiveLinq, you
can shape your view however you want using LINQ operators without
losing full updatability and bindability. "Bindability" means that
your views are not just static snapshots of their source data. They
are "live" and automatically reflect changes in the data. Your query
results are kept up-to-date without re-populating every time changes
in your data occur.
Simplifies MVVM
Simplify programming with the
widely-adopted Model-View-ViewModel pattern known as MVVM. You have
to write a lot more code to develop MVVM applications because of the
additional code layer, the ViewModel, and the synchronisation
between the Model and ViewModel data members. With Studio for Entity
Framework, you can use live views as your ViewModel and not have to
worry about writing any synchronisation code. Live views are
synchronised automatically with their sources and are much easier to
create. You can use Studio for Entity Framework with any MVVM
framework.
Code Freedom
Set up your data sources
directly on the designer surface, with easy-to-use property dialogs
and very little code to write. Configure the C1DataSource control
and apply server-side filter, sort and group descriptors quickly at
design-time. Of course, if you prefer to do everything in code you
have the freedom of doing so using the rich data class libraries.
