key to know:
Using the control is very easy and just needs adding the javascript code from the source page.
On the textbox on which the formatting needs to be applied, use the following code

onkeypress="return ValidateNumberKeyPress(this, event);" onkeyup="ValidateNumberKeyUp(this);"
onblur="ValidateAndFormatNumber(this)"
