SetFormFieldOnStateName(Int32,Int32,String) Method
In This Topic
Sets the string representation of the normal appearance (the On state, same as the radio button's choice attribute) of a required form field, here a child radio button in a group, 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 radio button and it is used when a radio button is not interacting with the user and for printing. As said, this method is only applicable to radio buttons.
If this attribute is not defined for the specified child radio button, 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.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.
- OnStateName
- A string representation of the On state (radio button's choice attribute) of the specified child radio button in a group.
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.
