PdfTextFieldDoNotScroll Property

public bool DoNotScroll { get; set; }

Public Property DoNotScroll As Boolean
	Get
	Set

Property Value

If true, the text field can not scroll (horizontally for single-line fields, vertically for multiple-line fields) to accommodate more text than fits; if false, the form field's text can be scrolled and accomidate any amount of text (unless limited by MaxLength). Additionally if true, once the field is full, no further text will be accepted for interactive form filling. (NOTE: Because of a known bug in Firefox, input in this browser may not be properly limited.)

This property can not be changed if IsLocked is true.
