GetFormFieldMultiLine Method (GdPicturePDF)
In This Topic
Returns, if the Multiline flag of a required form field, here a text field, is set. The text field is specified by its unique form field's identifier and it is related to the currently loaded PDF document. As stated, this flag is only specific to text fields, so this method is explicitly applicable to text form field objects.
If this flag is set, then the text field can contain multiple lines of text. It it is not set, the field's text is restricted to a single line.
Syntax
'Declaration
Public Function GetFormFieldMultiLine( _
ByVal As Integer _
) As Boolean
public bool GetFormFieldMultiLine(
int
)
public function GetFormFieldMultiLine(
: Integer
): Boolean;
public function GetFormFieldMultiLine(
: int
) : boolean;
public: bool GetFormFieldMultiLine(

public:
bool GetFormFieldMultiLine(
int

Parameters
- FieldId
- A unique form field identifier specifying a required form field object. You can obtain this identifier using these methods: AddTextFormField(Single,Single,Single,Single,String,String,Boolean,String,Single,Byte,Byte,Byte), GetFormFieldId or GetFormFieldChildID.
Return Value
true if the Multiline flag of the specified text field is set, otherwise false. The
GetStat method can be subsequently used to determine if this method has been successful.
