I am trying to check one condition when i m checking a particular checkbox.below is the code

Private Sub CheckBox4_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox4.CheckedChanged
        If CheckBox4.Checked Then
            check_CL()
        End If

Please show that control from the .Designer.cs page.. – Vishal Suthar
it's a winform application...how to show the designer.cs..?? – Snehasish
You must not have added registered the event. Register the event from designer. Verify it from your Designer>Properties>Events section – nawfal
Open the Form in Designer view and double click on the CheckBox4 control. This will cause VB to focus on the Code Behind file and will even create a Sub for the Event. Make sure you put your code there – Ahmad
I wrote the code after double clicking only..@Ahmad San – Snehasish

From your arguments it looks that you have performed appropriate steps. I would suggest that you should look for this piece of code:

   RemoveHandler CheckBox4.CheckedChanged, AddressOf CheckBox4_CheckedChanged

It is possible that you have unregistered handler somewhere in code either in .vb or .designer.vb

Have you tried using the full code to see if it works?

If CheckBox4.Checked = True Then
  check_CL()
End If
