Hi

Not sure if you are asking about a CheckedListBox or not. Anyway, this code could be applied to most controls. This is an example project. Start new and put a CheckedListBox1 and a Button 1onto Form1 and try it out. If it is doing what is required then apply it to your own code. Remember, you don't need to do it through a Button Click event, you can just use the one line of code anywhere and it will yoggle the Enabled state of the control each time it is executed.

' Form1 with CheckedListBox1 and   
' Button1  
Option Strict On  
Option Explicit On  
Public Class Form1  
	Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click  
		CheckedListBox1.Enabled = Not CheckedListBox1.Enabled  
	End Sub  
End Class

You can handle events like ItemCheck

Dim bDisableCheck As Boolean = False  

After ListView creation :

 bDisableCheck = True  

ItemCheck :

Private Sub ListView1_ItemCheck1(ByVal sender As Object, ByVal e As System.Windows.Forms.ItemCheckEventArgs) Handles ListView1.ItemCheck  
    If bDisableCheck Then  
        e.NewValue = e.CurrentValue  
    End If       
End Sub
