[Closed] Change Handlers & dotNet

Hi guys, i was testing a kind of simple “Position Inspector” using a .net dataGridView object and “When transform” change handler. The problem is that position coords displayed on the DGV, updates too slow when moving the box over long distances. Is that normal?, is there a better or faster way to expose transform data on a dataGridView object?.

function testChangeHandler =
(
	box name:"testBox" -- test object
	select $testBox
	
	-- theForm
	theForm = dotNetObject "MaxCustomCOntrols.MaxForm"
	theForm.text = "DGV Change Handler Test"
	theForm.width = 300
	theForm.height = 200
	theForm.topMost = true

	-- The dataGridView
	myDGV = dotNetObject "System.Windows.Forms.DataGridView"
	myDGV.location = dotNetObject "System.Drawing.Point" 0 0
	myDGV.defaultCellStyle.foreColor = (dotNetClass "System.Drawing.Color").black

	myCol1 = dotNetObject "System.Windows.Forms.DataGridViewTextBoxColumn"
	myCol1.headerText = "Column 1"
	myCol1.width = 100
	
	myCol2 = dotNetObject "System.Windows.Forms.DataGridViewTextBoxColumn"
	myCol2.headerText = "Column 2"
	myCol2.width = 100
		
	myDGV.columns.add myCol1
	myDGV.columns.add myCol2
		
	myDGV.width = 600
	myDGV.height = 200
	myDGV.rowCount = 3
	myDGV.columns.item [0].valueType = dotNetClass "System.Single"
	
	myDGV.rows.item [0].cells.item [0].value ="X Position"
	myDGV.rows.item [1].cells.item [0].value ="Y Position"
	myDGV.rows.item [2].cells.item [0].value ="Z Position"

	theForm.controls.add myDGV
	theForm.Show()
	theForm
	
	deleteAllChangeHandlers id:#whenTransform
	when transform $testBox changes id:#whenTransform do
	(
			myDGV.rows.item [0].cells.item [1].value =$.position.x
			myDGV.rows.item [1].cells.item [1].value =$.position.y
			myDGV.rows.item [2].cells.item [1].value =$.position.z
	)
	
) -- testChangeHandler

testChangeHandler ()
