Using The Silverlight DataGrid

核心提示： C#public Page(){InitializeComponent();//dg.ItemsSource = "H e l l o W o r l d !".Split();List<Data> source = new List<Data>

C#

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)
