Impossible d'ajouter un datagrid

**maxwel56** · 22/01/2010, 10h01

Bonjour,
J'aimerais ajouter a mon projet un datagrid, mais je n'y parviens pas.
En effet, lorsque je tente d'en ajouter, je reçois le message d'erreur suivant :

Value cannot be null
Parameter name : childorDescendant

Est ce que quelqu'un peut m'aider?
Merci d'avance

Si tu essayes d'ajouter ton Datagrid à la main dans le code XAML ?

Ouais ça m'est déjà arrivé. Du coup je fais plus de glisser-déposer de la toolbox, j'écris tout à la main.

Quand j'ajoute un datagrid directement ds le code ça me le souligne.
Je ne comprends pas pourquoi.

Est-ce que tu as rajouté la référence vers la dll qui contient le DataGrid ?
Est-ce que tu as rajouté la ligne dans le xaml pour référencer le namespace ?

**maxwel56** · 25/01/2010, 19h29

Oui j'ai ajouté la reference
System.windows.control.data.dll que j'ai trouvé ds c://microsoftsdks
J'ai également ajouté le namespace correspondant
Et même en fesant ceci ma balise <datagrid> n'est pas reconnu?
Est ce que cela peut venir d'un problème d'installation?
J'utilise Visual Studio 2010 Beta 2, je developpe en silverlight 4

Oui mais tu programmes au hasard...

Est-ce que tu as rajouté le namespace pour référencer ton assembly comme je t'ai indiqué dans le message précédent ?

Code xml :

xmlns:data="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data"

<data:DataGrid>

Montre tout ton code.
Est-ce que la référence apparait bien dans l'onglet .NET quand tu fais Ajouter une référence ?

Si tu vas en code behind et que tu tapes : DataGrid, est-ce qu'il est reconnu ? Est-ce qu'il te propose d'ajouter le namespace ?

Quel est le chemin exact de la dll que tu as ajouté comme référence ?
Si tu fais clic droit : Voir dans l'explorateur d'objet, est-ce que tu peux voir la classe DataGrid ?

**maxwel56** · 25/01/2010, 20h16

Dans le .net j'ai pas la dll correspondante au datagrid du coup je l'ai cherché sur mon ordinateur :
C:\Program Files\Microsoft SDKs\Silverlight\v4.0\Libraries\Client\System.Windows.Controls.Data.dll
