TextBox TextMod for SingleLine can be limited to length restrictions
TextBox TextMod is not good for multiline with maxlength, and you have to use the client's script to do length restrictions.
code show as below:
OnkeyPress = "Return (this.Value.Length <200);" // Input
OnPaste = "Return ((this.Value.Length WINDOW.CLIPBOARDDATA.GETDATA ('Text'). Length) <200);" / / Prevent Paste
