A unique form field identifier specifying a required form field object. You can obtain this identifier using methods like GetFormFieldId, GetFormFieldChildID or methods intended to add form fields.

GetFormFieldBorderColor(Int32) Method

In This Topic
Returns the border color of 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 method only returns the correct form field's border color if this attribute is specified in the form field object itself, otherwise the method will fail.

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 SetFormFieldBorderColor(Int32,Byte,Byte,Byte) 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 GetFormFieldBorderColor(Int32,Int32) method to determine the individual border color for each child radio button in a group instead.

Parameters

FieldId
A unique form field identifier specifying a required form field object. You can obtain this identifier using methods like GetFormFieldId, GetFormFieldChildID or methods intended to add form fields.

Return Value

The border color of the specified form field, if defined. The 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 GetStat method to identify the specific reason for the method's failure, if any.

Be aware that the form field's border color attribute is not assigned automatically when creating the form field. If this attribute is not specified, this method will fail.
