Hi,

I have read that one sets the checkstate of a checkbox with the values "Yes" and "Off".
Now we have a PDF-Form where we have to set "checked" by value "Ja" (German for "Yes").

How do we find out what string is needed to check the checkbox for a certain PDF-Form?

Regards,
Josef

Hi,

it seems, this is no information one gets from the developer guide.

We have password protected documents with checkboxes the “Yes-No”, “On-Off” values are replaced by values “100-Off” or others.

My question is:
How can we find out which value is for a certain checkbox appropriate to check/uncheck it by code.

Regards,
Josef

hello,

Have you tried this approach?

for (int i = 1; i <= QP.FormFieldCount(); i++)
                    {
                        string title = QP.GetFormFieldTitle(i);
                        string hint = QP.GetFormFieldDescription(i);
                        string s = QP.GetFormFieldValue(i);
                        int type = QP.GetFormFieldType(i);

                            if (type == 3 || type == 4) // Radio or CheckBox
                            {
                                int sc = QP.GetFormFieldSubCount(i);
                                for (int j = 1; j <= sc; j++)
                                {
                                    string sfn = QP.GetFormFieldSubName(i, j);
                                    textBox1.AppendText(sfn);
                                    if (j != sc)
                                        textBox1.AppendText("|");
                                }
                            }
