GdPicture14 Namespace / GdPicturePDF Class / SetFormFieldNormalCaption Method

Example





In This Topic
SetFormFieldNormalCaption Method (GdPicturePDF)
In This Topic
Sets the normal caption of a required form field, here a button form field, that is specified by its unique form field's identifier and it is related to the currently loaded PDF document. As stated, this attribute is only specific to button form fields, so this method is explicitly applicable to button form field objects.

This caption is displayed when the button form field is not interacting with the user.

Syntax
'Declaration
 
Public Function SetFormFieldNormalCaption( _
   ByVal FieldId As Integer, _
   ByVal NormalCaption As String _
) As GdPictureStatus
public GdPictureStatus SetFormFieldNormalCaption( 
   int FieldId,
   string NormalCaption
)
public function SetFormFieldNormalCaption( 
    FieldId: Integer;
    NormalCaption: String
): GdPictureStatus; 
public function SetFormFieldNormalCaption( 
   FieldId : int,
   NormalCaption : String
) : GdPictureStatus;
public: GdPictureStatus SetFormFieldNormalCaption( 
   int FieldId,
   string* NormalCaption
) 
public:
GdPictureStatus SetFormFieldNormalCaption( 
   int FieldId,
   String^ NormalCaption
) 

Parameters

FieldId
A unique form field identifier specifying a required form field object. You can obtain this identifier using methods like GdPicturePDF.GetFormFieldId, GdPicturePDF.GetFormFieldChildID or methods intended to add form fields.
NormalCaption
The new normal caption of the specified form field.

Return Value

A member of the GdPictureStatus enumeration. If the method has been successfully followed, then the return value is GdPictureStatus.OK.

We strongly recommend always checking this status first.

Remarks
This method is only allowed for use with non-encrypted documents.

Just to remind you, that this method is only meaningful for button form fields (these are push buttons, check boxes, radio buttons), otherwise it will fail.

Example
How to find out and change the caption of all push buttons in the current document.
