When I call the DeleteFormField function with the ID of the child form field it deletes the parent too.

But if I save the document to a file all of the form fields are still there.

I'm using v7.26 of the library at the moment.

I'm going to try the current version and see if that fixes it.

Do you have any sample code we can look at ?

Here is some test code I wrote that is performing as expected in 9.12

QP.LoadFromFile("formfields_2parents2children.pdf", "");

int c = QP.FormFieldCount();

string s = "Before DeleteFormField() - Count=" + c.ToString() + "\n";

for (int i = 1; i <= c; i++)

QP.SetFormFieldValue(i, i.ToString() + "_" + QP.GetFormFieldValue(i));

for (int i = 1; i <= c; i++)

s += String.Format("{0} : Name={1} : Value={2}\n", QP.GetFormFieldType(i), QP.GetFormFieldTitle(i), QP.GetFormFieldValue(i));

QP.DeleteFormField(6);

QP.DeleteFormField(2);

c = QP.FormFieldCount();

s += "After DeleteFormField() - Count=" + c.ToString() + "\n";

for (int i = 1; i <= c; i++)

s += String.Format("{0} : Name={1} : Value={2}\n", QP.GetFormFieldType(i), QP.GetFormFieldTitle(i), QP.GetFormFieldValue(i));

MessageBox.Show(s);

QP.SaveToFile("out.pdf");

Process.Start("out.pdf");

Before DeleteFormField() - Count=6

7 : Name=F1 : Value=

1 : Name=F1.Child1 : Value=2_F1.Child1.Text

1 : Name=F1.Child2 : Value=3_F1.Child2.Text

7 : Name=F2 : Value=

1 : Name=F2.Child1 : Value=5_F2.Child1.Text

1 : Name=F2.Child2 : Value=6_F2.Child2.Text

After DeleteFormField() - Count=4

7 : Name=F1 : Value=

1 : Name=F1.Child2 : Value=3_F1.Child2.Text

7 : Name=F2 : Value=

1 : Name=F2.Child1 : Value=5_F2.Child1.Text
