silverlight dataform control unavailable

I have RIA services installed and also have silverlight 3.0 but there is no system.windows.controls.data.dataform . On account of this, I am unable to use dataform control . WHat should I do?I have also tried to download the same but u开发者_如何学Gonable to find it.

DataForm is not currently in the SDK. Its found in the Toolkit. Download and install the Nov09 Silverlight Toolkit for Silverlight 3.

You need to add the System.Windows.Controls.Data.DataForm.Toolkit reference to your project. Then the DataForm will be available in the System.Windows.Controls namespace.
