SetFormFieldBorderColor(Int32,Int32,Byte,Byte,Byte) Method

In This Topic

Sets the border color of a required form field, here a child radio button in a group. The radio button group is specified by its unique form field's identifier and it is related to the currently loaded PDF document. Please note that every single child radio button in a group of radio buttons within a radio button field can have its own border color defined, that you are allowed to set using this method. As said, this method is only applicable to radio buttons.

Please use this method right after adding the required form field on the page, as the form field's border color attribute is not assigned automatically. Otherwise, the form field may display invisible.

This method uses the RGB color space for specifying the required color.

public:
GdPictureStatus SetFormFieldBorderColor( 
   int FieldId,
   int ChildIdx,
   byte Red,
   byte Green,
   byte Blue
)

Parameters

FieldId: A unique form field identifier specifying a required form field object. You can obtain this identifier using these methods: GdPicturePDF.AddRadioButtonFormField, GdPicturePDF.GetFormFieldId or GdPicturePDF.GetFormFieldChildID.
ChildIdx: The index of the required child radio button in a group. It must be a value from 0 to GdPicturePDF.GetFormFieldChildCount-1.
It is simply a sequence index of a radio button in a group, it does not correspond to the unique form field's identifier.
Red: The amount of red color to be used for the resulting color. Use the value between 0 and 255.
Green: The amount of green color to be used for the resulting color. Use the value between 0 and 255.
Blue: The amount of blue color to be used for the resulting color. Use the value between 0 and 255.

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. At the same, this method is only meaningful for radio buttons, otherwise it will fail.

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

Example

How to specify the border color for the newly added radio button group. Each child radio button will have its own border color.
