[Closed] Dotnet location

I don’t understand why when i click on the check box it doesn’t move, it appears to only be making it smaller.

 (
 	rollout test_rl "test" width:100 height:400
 	(
 		fn function_check_box fn_check_button =
 		(
 			fn_check_button.text = ""
 			fn_check_button.Appearance = fn_check_button.Appearance.Button
 			fn_check_button.FlatStyle = fn_check_button.FlatStyle.Flat
 			fn_check_button.FlatAppearance.CheckedBackColor = fn_check_button.FlatAppearance.CheckedBackColor.Orange
 			fn_check_button.ForeColor = (dotnetclass "system.drawing.color").FromArgb 10 10 10
 			fn_check_button.BackColor = (dotnetclass "system.drawing.color").FromArgb 250 250 250
 			
 			return fn_check_button
 		)
 		
 		dotnetcontrol left_box "system.windows.forms.checkbox" pos:[80,0] width:20 height:400
 		
 		
 		on test_rl open do
 		(	
 			function_check_box left_box
 		)
 		
 		on left_box mouseclick do
 		(
 			if left_box.checked == true then
 			(
 				left_box.location = (dotNetObject "system.drawing.point" -5 0)
 
 			)else(
 				left_box.location = (dotNetObject "system.drawing.point" 0 0)
 			)
 		)
 	)
 	createdialog test_rl style:#(#style_toolwindow,#style_sysmenu)
 )
