I can populate fields in a XFA document as long as it it a text field.

I don't see anyway to check a field that is a Check Box however.

Does anyone know how to do that?

Thanks

Hi,

perhaps this guide from the online reference will be a help?

I appreciate the reference. I have been able to extract data from a form and mostly can place data into a form. This guide does give me a few more options I hadn't considered so thanks.

The exception for me at the moment is a CheckBox. I can see how to alter the format of the check but so far can only place a check by manually doing that in the form.

In reading the data from a CheckBox when it is unchecked the field value is 'Off'. So one might think that placing 'On' into the checkbox would activate the check mark. This does not work for me however.

I am attempting to place that data with this code:

PDF.SetXFAFormFieldValue('Form1099-S/c1_3', 'On'); //Does not produce the check mark

Doing something similar works just fine it the field is a text box but not when its a check box.

Thanks again

Hi,

fpr normal forms (not XFA) it works like this:
// ...
                   QP.SetNeedAppearances(1);
                   QP.SetFormFieldValueByTitle( FieldName, FieldValue );
                   nresult := QP.FindFormFieldByTitle(FieldName);
                   QP.UpdateAppearanceStream(nresult);
// ...
And you're right a value "On" oder "Off" will change the checkbox and regarding XFA it should work similar ...? BTW: Is your fieldname correct with the slash in it?

This works fine with text fields but I can't get either method to work with a check box.

for me it works fine ;-)
Perhaps it would help if you're able to post more than only one single line of code...
