The ItemCreated event occurs for each new item that is added to the Items collection of the combobox.

If the item is added from a data source (the DataSource or DataSourceID property specifies the source of the items), it is a good idea to use the ItemDataBound event instead. ItemCreated occurs before the ItemDataBound event (before any item properties have been set to reflect the data in the data source).

The ItemCreated event handler receives two arguments:

  1. The RadComboBox that is loading items. This argument is of type object, but can be cast to the RadComboBox type.

  2. An EventArgs object. This object has an Item property, which provides access to the item that has just been added.

Use the ItemCreated event handler to make changes to items as they are added to the combobox:

        protected void Page_Load(object sender, EventArgs e) 
            if (!Page.IsPostBack)     

        protected void RadComboBox1_ItemCreated(object sender, RadComboBoxItemEventArgs e) 
            RadComboBoxItem newItem = e.Item; 
            if (newItem.Text == "Paris")            
                newItem.Enabled = false; 

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

            If Not Page.IsPostBack Then

            End If
        End Sub

        Protected Sub RadComboBox1_ItemCreated(ByVal sender As Object, ByVal e As RadComboBoxItemEventArgs) Handles RadComboBox1.ItemCreated

            Dim newItem As RadComboBoxItem = e.Item
            If newItem.Text = "Paris" Then
                newItem.Enabled = False
            End If
        End Sub
