Binding to Array or ArrayList

You can bind RadToolBar to an object-based data source such as ObjectDataSource or any class that implements the IEnumerable interface.

Binding to an object that supports IEnumerable

Instead of going through an ObjectDataSource, you can bind RadToolBar directly to any collection that implements the ICollection or IEnumerable interface.Mapping properties of the objects in the collection to properties of the buttons works exactly the same way as when using ObjectDataSource.

To bind directly to a collection, you must bind the toolbar at runtime, using the following steps:

  1. Create the collection.

  2. Add items to the collection. Depending on the type of the collection, these can be strings, or more complex objects with properties that correspond to RadToolBarButton properties.

  3. Set the DataSource property of RadToolBar to the instance of the collection.

  4. Call the DataBind method.

The following example shows a toolbar bound to an ArrayList. The items in the list are simple strings, so the buttons map their Text property automatically to the strings in the list:

private ArrayList GenerateArrayList()
    ArrayList itemsList = new ArrayList();
    return itemsList;
protected void Page_Load(object sender, EventArgs e)
    if (!IsPostBack)
        RadToolBar1.DataSource = GenerateArrayList();
Private Function GenerateArrayList() As ArrayList

    Dim itemsList As New ArrayList()
    Return itemsList

End Function 'GenerateArrayList

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

    If Not IsPostBack Then
        RadToolBar1.DataSource = GenerateArrayList()
    End If

End Sub
