SetFormFieldOnStateName(Int32,String) Method
In This Topic
Sets the string representation of the normal appearance (the On state) of a required form field, here a check box, that is specified by its unique form field's identifier and it is related to the currently loaded PDF document. The normal appearance represents the checked state of a check box and it is used when a check box is not interacting with the user and for printing. As said, this method is only applicable to check boxes.
If this attribute is not defined for the specified check box, then the predefined value for the On state is "On" by default.

Parameters
- FieldId
- A unique form field identifier specifying a required form field object. You can obtain this identifier using these methods: GdPicturePDF.AddCheckBoxFormField, GdPicturePDF.GetFormFieldId or GdPicturePDF.GetFormFieldChildID.
- OnStateName
- A string representation of the On state of the specified check box.
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.
