BulletedList.Click Event

Note: This event is new in the .NET Framework version 2.0.

Occurs when a link button in a BulletedList control is clicked.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

'Declaration
Public Event Click As BulletedListEventHandler
'Usage
Dim instance As BulletedList
Dim handler As BulletedListEventHandler

AddHandler instance.Click, handler

/** @event */
public void add_Click (BulletedListEventHandler value)

/** @event */
public void remove_Click (BulletedListEventHandler value)

JScript supports the use of events, but not the declaration of new ones.

The Click event is raised when a list item in a BulletedList control is clicked. To enable list items in a BulletedList control to raise the Click event, the DisplayMode property first must be set to the value LinkButton.

Raising an event invokes the event handler through a delegate. For more information about handling events, see Consuming Events.

The following code example demonstrates how to specify and code an event handler for the Click event of a BulletedList control. When a list item is clicked, a message is displayed in a Label control on the page. All the link buttons in the bulleted list raise the same Click event. To determine which link button raised the event, the BulletedListEventArgs argument is examined.

        Sub ItemsBulletedList_Click(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.BulletedListEventArgs)
            ' Change the message displayed in the label based on the index
            ' of the list item that was clicked.
            Select Case (e.Index)
                Case 0
                    Message.Text = "You clicked list item 1."
                Case 1
                    Message.Text = "You clicked list item 2."
                Case 2
                    Message.Text = "You clicked list item 3."
                Case Else
                    Throw New Exception("You did not click a valid list item.")
            End Select
