Using The Silverlight DataGrid

Article
03/21/2008

This post has been updated to work with the RTW version of the Silverlight 2 DataGrid. The code examples are not guaranteed to work with previous Beta versions of the DataGrid. Read more about the features that the Silverlight 2 DataGrid has to offer...

If you have ever worked on an application that displayed large amounts of data, one of the cornerstones of your application was probably a DataGrid control. We have provided four .NET DataGrids over the years, two for ASP.NET and two for Windows Forms, but until now Silverlight and WPF were left out of the party.

At MIX 2008 we shipped the first preview of the Silverlight DataGrid and a preview of it in WPF was also shown. Now that it is out there people want to know how to use it. If you are one of those people, then you have come to the right place. Here's a quick guide on how to get up and running with a Silverlight DataGrid.

Step 0: Create A Silverlight Project

Start a new Silverlight Application as outlined in my previous post. When given the option, choose the default "Add a new ASP.NET Web project" option.

Step 1: Add a DataGrid

If everything went smoothly in the previous step, your project should be loaded and opened to Page.xaml. Now just find the DataGrid on the Toolbox and drag it into the root layout Grid named "LayoutRoot".

DataGridOnToolBox

This does a few things behind the scenes:

It adds a reference in your Silverlight project to System.Windows.Controls.Data
It adds an xmlns called "data" to the root UserControl that specifies that the DataGrid is in the System.Windows.Controls namespace and located in the System.Windows.Controls.Data assembly
- ```
 xmlns:data="clr-namespace:System.Windows.Controls;
 assembly=System.Windows.Controls.Data"
```
It adds an instance of the DataGrid as a child of "LayoutRoot"
- ```
 <data:DataGrid></data:DataGrid>
```

If you are the type of the person who likes to see things working after each step, feel free to F5 (choose the option to allow debugging in the popup) and take in the awesome sight that is an empty DataGrid.

EmptyDataGrid

Not much here, so lets fill it with something.

Step 2: Set the ItemsSource and AutoGenerateColumns

The way to make a DataGrid interesting is by giving it some data. This is done through the DataGrid's ItemsSource property. This is same property that other controls in WPF and Silverlight, such as ListBox, use to specify where they will get their data. The one difference here is that you cannot place arbitrary content in it and have it create a collection for you.

Instead you need to provide it a collection of anything that implements IEnumerable such as a List or ObservableCollection.

The ItemsSource can be specified inline in XAML such as:

 <data:DataGrid x:Name="dg">
    <data:DataGrid.ItemsSource>
        <!--Something that implements IEnumerable -->
    </data:DataGrid.ItemsSource>
</data:DataGrid>

However, it is more commonly set in code behind, which is what we will do in this example.

Step 2 A: Name the DataGrid and build

Before we go to the code behind you will want to be sure to give the DataGrid a name such as "dg". Also be sure to build so that you can reference the DataGrid in code:

 <my:DataGrid x:Name="dg" ></my:DataGrid>

Step 2 B: Create and Set the Items Source

Now that the DataGrid is ready to have its ItemsSource set, go to the Page's constructor located in the code behind file for Page.xaml (A handy shortcut to do this from within Page.xaml is F7) and add the following line below InitializeComponent:

 public Page()
{
    InitializeComponent();
    dg.ItemsSource = "H e l l o W o r l d !".Split();
}

 Public Sub New()
    InitializeComponent()
    dg.ItemsSource = "H e l l o W o r l d !".Split()
End Sub

(If you get the build error: "The name 'dg' does not exist in the current context" with the code above be sure to build a second time so that the name has a chance to propagate)

One of the easiest ways to generate an IEnumerable collection is String.Split. When the resulting array is set as the ItemsSource of the DataGrid a column will be automatically generated since AutoGenerateColumns is true. When you run the application, it will look like this:

StringSplitDataGrid

This is a little better, but so far this could be done with a ListBox. Lets add some more complicated data so that we actually need to use a DataGrid.

Add a new class to your Silverlight project (not the Web project) and name it "Data".

AddNewClass

Then add a few properties to bind to.

If you are using C#, you can use the great 3.0 Automatic Properties feature.

 public class Data
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public int Age { get; set; }
    public bool Available { get; set; }
}

 Public Class Data
    Private _firstName As String
    Private _lastName As String
    Private _age As Integer
    Private _available As Boolean

    Property FirstName() As String
        Get
            Return _firstName
        End Get
        Set(ByVal value As String)
            _firstName = value
        End Set
    End Property

    Property LastName() As String
        Get
            Return _lastName
        End Get
        Set(ByVal value As String)
            _lastName = value
        End Set
    End Property

    Property Age() As Integer
        Get
            Return _age
        End Get
        Set(ByVal value As Integer)
            _age = value
        End Set
    End Property

    Property Available() As Boolean
        Get
            Return _available
        End Get
        Set(ByVal value As Boolean)
            _available = value
        End Set
    End Property
End Class

Once the Data class is defined, it can now be used to provide data for the DataGrid. Go back to the code behind file for Page.xaml and replace the previous ItemsSource assignment with the following. A useful trick here is to use the C# and VB 3.0 Object Initializer feature to initialize the Data objects as we add them to the List.

 public Page()
{
    InitializeComponent();
    //dg.ItemsSource = "H e l l o W o r l d !".Split();

    List<Data> source = new List<Data>();
    int itemsCount = 100;

    for (int i = 0; i < itemsCount; i++)
    {
        source.Add(new Data() 
        { 
            FirstName = "First", 
            LastName = "Last", 
            Age = i, 
            Available = (i % 2 == 0) 
        });
    }

    dg.ItemsSource = source;
}

 Public Sub New()
    InitializeComponent()
    'dg.ItemsSource = "H e l l o W o r l d !".Split()

    Dim Source As List(Of Data) = New List(Of Data)
    Dim ItemsCount As Integer = 100

    For index As Integer = 1 To ItemsCount
        Source.Add(New Data() With _
        { _
            .FirstName = "First", _
            .LastName = "Last", _
            .Age = index, _      .Available = (index Mod 2 = 0) _
        })
    Next

    dg.ItemsSource = Source
End Sub

When you run this you will notice that columns are created for you. This is because auto-generation takes over, using reflection to create a column for each property in Data, setting the column header to the name of the property, and choosing default column types based on the property type. For instance the Available column is a DataGridCheckBoxColumn. (If you did not want this behavior, but rather wanted to choose your own columns, you can do this by setting the DataGrid's AutoGenerateColumns property to false. For information on choosing your own columns see my post on Defining Columns for a Silverlight DataGrid)

DataListDataGrid

Step 3: Simple Customization of the DataGrid

The easiest way to customize the DataGrid is through a variety of properties. The other two ways are through Styles and Templates which will be covered in future posts. Some of the most useful properties for customization are:

GridLinesVisibility & HeadersVisibility

These properties are enumerations that control what gridlines and headers are displayed.

RowBackground & AlternatingRowBackground

These properties are shortcuts to setting the background color for both rows and alternating rows.

ColumnWidth & RowHeight

These properties set the default column width and default row height.

IsReadOnly & CanUserResizeColumns

These properties control if the end user can edit the data in the grid and if the columns can be resized.

For instance if you set the following properties to the following values:

 <data:DataGrid x:Name="dg" AutoGenerateColumns="True" 
    GridlinesVisibility="None" HeadersVisibility="All"
    RowBackground="Cornsilk" AlternatingRowBackground="LemonChiffon"
    ColumnWidth="85" RowHeight="30"
    IsReadOnly="True" CanUserResizeColumns="False"
    >
</data:DataGrid>

You would get this:

CustomizedDataGrid

Step 4: Enjoy

Now that you have the basics, enjoy using the DataGrid. Next time I'll go into how to explicitly define and customize columns instead of using auto generation.

Also, you can read more about the features that the Silverlight 2 DataGrid has to offer...

I highly recommend if you are interested in adding a SQL data source, yes you can do this by creating a webservice and using the LINQ2SQL functions. Remember SL 2.0 is client side so you are going to have to do something still serving it that sql data.. In fact with LINQ you can use any kind data you want.. Check out this video blog tutorial from the Swiss MSDN TEAM.. http://blogs.msdn.com/swiss_dpe_team/archive/2008/03/17/silverlight-2-beta1-wcf-linq-to-sql-a-powerfull-combination.aspx After watching this you should find it very easy to be mapping SQL data to the datagrid... -Don

Hi Don; Thank you for the link. Before I get started to develop a complex middle tier data server (using WCF) for my SL client (which can become fairly complex, I like to know what are the plans from MSFT to provide us with some tools for the middle tier. I like to know if Astoria is the solution for SL or id SL team have a more customized solution for SL? Again, I don't want to re-invent the wheel, if the team is already working on it. I'm going to watch the video now, thank you again!

Hi Diego, Based on what you are saying I'm guessing that what you have the DataGrid bound to is something like an IEnumerable which does not persist changes made to it. If this is the case, then when you scroll a row out of view and then back in the row's data is being refreshed from the data source due to a performance increasing process called UI virtualization. Since the IEnumerable doesn't accept the changes, you get the original value. To fix this behavior, instead bind your DataGrid to a List or ObservableCollection. If you are using XLinq to query your XML then you can use the shortcut method .ToList<T> on the collection that was returned from the Linq expression. Hope this helps. -Scott

March 25, 2008
Ethan, I'll be posting a topic on it however there are a dozen or so topics in the queue before it so it could be a while. To get you started, be sure to bind to an ObservableCollection<T> or some other collection that implements INotifyCollectionChanged. Then you can change the contents of the collection (such as sorting it) and have these changes reflected in your DataGrid. Malky, The answer to your question is actually the same as Ethan's. To avoid the behavior that you are seeing you need to bind to something that gives collection changed notifications so that the DataGrid knows to update itself. Go ahead and use an ObservableCollection and you should see the behavior that you want. -Scott

Scott, I appreciate the blogs and the great work y'all are doing on the framework. But, I'm really lost on one thing: I want to make a DataGrid with 7 columns, the value of which each come from a separate table. All tables are related. So, I'm struggling with figuring out how I am supposed to get that data into a List or Collection of non-anonymous, non-DataRow objects from the server to the client. I'm trying to do the whole SL/WCF/EF thing here, I can't seem to figure out this piece.

I was unable to access the Cells property of the DataGridRow class, later i found it but marked as internal, why is that?

I solved the problem. There is a bug in dragging items from the toolbox to the XAML. I already had a TabControl in the XAML which created the appropriate reference at the top. Apparently when you do this again with a control that references a different assembly it fails. nothing is added to the top (i.e. xmlns:data="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data" should be added). If I temporarily delete the reference for the TabControl add the DataGrid - everything works correctly and then I add the reference for the TabControl back in. greg

Hey Scott, just saw your session on Data Driven RIA's. Good talk. Nice stuff. I need to ask you though if you could elaborate on the groupby functionality in the out of band release of the datagrid. To me, that seems more like a reporting type of tool and not as useful as a master - detail - detail relationship that I could have built in traditional datasets. For example, if you have a collection of Authors who have each have a collection of books and also a collection of videos. In ASP.Net I would just build a relationship object between those three tables. It would be nice to be able to decompose that master record into the many collections which it may contain. I would also appreciate any feedback you could provide on performing this functionality on a UDF which throws up a table. In my real world, I might need to pull together 7 different tables for my forms which might involve unions, and the best way to do that is through a UDF. Forget about ASP Entity Framework at the moment as feel it is only about half backed.

For a datagrid, how can I bind data without any code behind I mean my data will be defined in the xaml file. I don't want code anything in the c# or VB class. I know, in a c# code behind class, it is easy to do that. But, what I am trying to do is to dynamic generate xaml file in a string on server side, and send the string to the client side by using WCF service, then, load the xaml file string using XmlReader.Load(fileString), finally the xaml file will be displayed in the client side browser. There're so many reasons that I can't send data to client side and using c# class to load data to the class properties and sign it to the Datagrid.ItemSource. So, I have to build everything in the xaml file string. Can I do it? Thanks.

Hello, The grid is awesome, but there are definately times when you want to dynamically build the grid. Also ...DataSet/DataTable? The serialization can happen, you just need to find a way to put the string indexers on the DataRow after serialization. Just replace the underlying ListDictionary<oibject> with a Dictionary<string, object>. Actually, don't sweat the serialization, just put the Data Objects in the Silverlight side and support them in the grid.

IMO, data virtualization is a must have for the grid. I don't care whether it performs nicely with millions of rows. For one thing, I don't want to keep them in memory, and - more importantly - I don't want to fetch them from my server at once. This is quite a show stopper for us I'm afraid.

I would think that something that baisic would be well documented, heck it should be automatic but it's not. Thanks for wasting a full day and starting another one...

Scott -- Please help. That is a nice article. Can you please explain a bit more? If one sets AutoGenerateColumns=false then how can one add columns programmatically to a Silverlight DataGrid? Please advise. Thank you. -- Mark Kamoski

Hi Mac, To enable scrollbars, make sure that your DataGrid is either in a control that constrains its height (like a Grid) or explicitly set a height. Mark, Looks like you already found the article, but for others who are interested: blogs.msdn.com/.../defining-columns-for-a-silverlight-datagrid.aspx Hope this helps! -Scott

Hi, And if I don't know the exact number of columns at design time? how do I fullfill the datagrid dynamically without a class? Regards
