GdPicture.NET.14.API
GdPicture14 Namespace / GdPicturePDF Class / SetFormFieldAction Method
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.
A unique action identifier specifying a required action object. You can obtain this identifier when creating an action, for example, using the GdPicturePDF.NewActionGoTo, GdPicturePDF.NewActionGoToR, GdPicturePDF.NewActionLaunch, GdPicturePDF.NewActionJavaScript, GdPicturePDF.NewActionNamed or GdPicturePDF.NewActionURI methods.
Example





In This Topic
SetFormFieldAction Method (GdPicturePDF)
In This Topic
Associates a specified action (identified with a unique action identifier) with a required form field, that is specified by its unique form field's identifier and it is related to the currently loaded PDF document. At this time it is supported by the toolkit to only associate one action within one form field.
Syntax
'Declaration
 

Public Function SetFormFieldAction( _
   ByVal FieldId As Integer, _
   ByVal ActionID As Integer _
) As GdPictureStatus
public GdPictureStatus SetFormFieldAction( 
   int FieldId,
   int ActionID
)
public function SetFormFieldAction( 
    FieldId: Integer;
    ActionID: Integer
): GdPictureStatus; 
public function SetFormFieldAction( 
   FieldId : int,
   ActionID : int
) : GdPictureStatus;
public: GdPictureStatus SetFormFieldAction( 
   int FieldId,
   int ActionID
) 
public:
GdPictureStatus SetFormFieldAction( 
   int FieldId,
   int ActionID
)

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.
ActionID
A unique action identifier specifying a required action object. You can obtain this identifier when creating an action, for example, using the GdPicturePDF.NewActionGoTo, GdPicturePDF.NewActionGoToR, GdPicturePDF.NewActionLaunch, GdPicturePDF.NewActionJavaScript, GdPicturePDF.NewActionNamed or GdPicturePDF.NewActionURI methods.

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.

Also be aware that at this time it is not supported by the toolkit to add multiple actions per one form field.
