Introduction
In this article we will see how we can filter a Textbox on
Keyboard inputs. We will see how we can block Numeric input from Keyboard.
Creating Silverlight Project
Fire up Visual Studio 2010 and create a new Silverlight 4
Business Application Project. Name it as RIASilverlight4Sample01.
After creating the Project, you would see a change in
Solution Structure. I meant to say that different Layers are separated from each
other using different Folders.
See the below figure for the Solution Structure in VS
2010.
We will have our own Page to the Project. Add A Silverlight
Page to the "View" Folder, name it as Employee.xaml.
I have added the below XAML code to have the link button in
the MainPage.xaml
We would add a DataGrid to
the Employee.xaml page which will be useful for our need.
Now Add An Entity Model to
the Web Project.
The following screenshots are
for the reference how to proceed further. You can use it as step by step.
We would change the table and
field names for easy use.
Add A Domain Service Class to
the Web project and name it as "EmployeeDomainService".
If you are not getting any
Entity Frameworks listed, then just press cancel and rebuild the Web Project.
And do the above steps again.
You would see the
EmployeeDomainService.cs file has all the methods related to CRUD operations.
See the below figure
Change the GetEmployees
method to below code.
Now Re Build the solution.
Building the solution generates the Domain Context and
entities in the client project.
Open Employee.xaml.cs and add
the following namespaces.
Add the following Context and
use it as shown below:
I have changed the DataGrid's
AutoGenerateColumns to False and made the IsReadOnly property to True. I have
customized the columns structure as follows:
Now we are ready, run the
application and click on the Employee Details Link on the top right. You would
get the results as shown in below figure.
Hope this article helps for
the beginning.
