FormFieldHasBorderColor(Int32) Method

In This Topic

Returns, if the border color attribute is defined for a required form field, that is specified by its unique form field's identifier and it is related to the currently loaded PDF document.

The form field's border color attribute is not assigned automatically when creating the form field. However, you can specify the border color using the GdPicturePDF.SetFormFieldBorderColor method right after adding the required form field on the page. Otherwise, the form field may display invisible.

Be aware that if the border color differs for each single child radio button in a group of radio buttons within a radio button field, this method will fail. Please use the GdPicturePDF.FormFieldHasBorderColor method instead to find out, if the border color attribute is defined for each child radio button in a group.

'Declaration
 
Public Overloads Function FormFieldHasBorderColor( _
   ByVal FieldId As Integer _
) As Boolean

public bool FormFieldHasBorderColor( 
   int FieldId
)

public function FormFieldHasBorderColor( 
    FieldId: Integer
): Boolean;

public function FormFieldHasBorderColor( 
   FieldId : int
) : boolean;

public: bool FormFieldHasBorderColor( 
   int FieldId
)

public:
bool FormFieldHasBorderColor( 
   int FieldId
)

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.

Return Value

true if the border color attribute is defined for the specified form field object, otherwise false. The GdPicturePDF.GetStat method can be subsequently used to determine if this method has been successful.

Remarks

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

It is recommend to use the GdPicturePDF.GetStat method to identify the specific reason for the method's failure, if any.

Just to remind you, that the form field's border color attribute is not assigned automatically when creating the form field.

Example

How to set the border color to only those form fields, which don't have any defined.
