CheckedListBox.DisplayMember Property

Gets or sets a string that specifies a property of the objects contained in the list box whose contents you want to display.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

'Declaration
<BrowsableAttribute(False)> _
Public Property DisplayMember As String

Property Value

Type: System.String
A string that specifies the name of a property of the objects contained in the list box. The default is an empty string ("").

By default the CheckedListBox displays the default string for the items it contains. However, the CheckedListBox can display diverse types of objects and you may want to change the displayed string by specifying the DisplayMember property. If the specified property does not exist, or the value of the DisplayMember property is an empty string (""), the results of the object's ToString method are displayed instead.

If the new value of the DisplayMember cannot be set, the previous value is maintained.

The following code example demonstrates initializing a CheckedListBox control by setting the CheckOnClick, SelectionMode, and ThreeDCheckBoxes properties. The example populates the CheckedListBox with controls and sets the DisplayMember to the Control.Name property of the control.

To run the example, paste the following code in a form containing a CheckedListBox named CheckedListBox1 and call the InitializeCheckListBox method from the form's constructor or Load method.


' This method initializes CheckedListBox1 with a list of all the controls
' on the form. It sets the selection mode to single selection and
' allows selection with a single click. It adds itself to the list before 
' adding itself to the form.
Friend WithEvents CheckedListBox1 As System.Windows.Forms.CheckedListBox

Private Sub InitializeCheckedListBox()
    Me.CheckedListBox1 = New CheckedListBox
    Me.CheckedListBox1.Location = New System.Drawing.Point(40, 90)
    Me.CheckedListBox1.CheckOnClick = True
    Me.CheckedListBox1.Name = "CheckedListBox1"
    Me.CheckedListBox1.Size = New System.Drawing.Size(120, 94)
    Me.CheckedListBox1.TabIndex = 1
    Me.CheckedListBox1.SelectionMode = SelectionMode.One
    Me.CheckedListBox1.ThreeDCheckBoxes = True

    Dim aControl As Control
    For Each aControl In Me.Controls
        Me.CheckedListBox1.Items.Add(aControl, False)
    Next

    Me.CheckedListBox1.DisplayMember = "Name"
    Me.CheckedListBox1.Items.Add(CheckedListBox1)
    Me.Controls.Add(Me.CheckedListBox1)
End Sub
