Unable to check the checkbox

Aspose.PDF Product Family
#1

I am able to update the text fields but facing issues in updating the checkboxes in the first form in attached document. Its been a struggle from days. please guide me on this.



I have tried something like

string[] names = doc.Form.XFA.FieldNames;

//set field values

doc.Form.XFA[names[13]] = “Off”;



tried this also, seems the field tracking is wrong

pdfForm.FillField(“form1[0].name[13]”, “Off”);







Thanks.

Hi there,


Thanks for your query. Please note CheckBox field in XFA has child node items which contains possible values for the field. You can obtain these values and set one of these values as following.

List<string> GetCheckBoxValues(Document doc, string fieldName)<o:p></o:p>

{<o:p></o:p>

XmlNode tmpl = doc.Form.XFA.GetFieldTemplate(fieldName);<o:p></o:p>

XmlNodeList items = tmpl.SelectNodes(“tpl:items/*”, doc.Form.XFA.NamespaceManager);<o:p></o:p>

List<string> res = new List<string>();<o:p></o:p>

foreach (XmlNode item in items)<o:p></o:p>

{<o:p></o:p>

res.Add(item.InnerText);<o:p></o:p>

}<o:p></o:p>

return res;<o:p></o:p>

}<o:p></o:p>

<o:p> </o:p>

Document doc = new Document(“g-28.pdf”);<o:p></o:p>

List<string> items = GetCheckBoxValues(doc, “form1[0].#subform[0].Line4_Checkbox[0]”);<o:p></o:p>

doc.Form.XFA[“form1[0].#subform[0].Line4_Checkbox[0]”] = items[0];<o:p></o:p>

doc.Save(“result.pdf”);<o:p></o:p>

<o:p> </o:p>

In continuation to my above query, there are other checkboxes which are in group, they are no working if I use same logic which you have shared



List items1 = GetCheckBoxValues(doc, “form1[0].#subform[0].Line3b_Unit[2]”);

doc.Form.XFA[“form1[0].#subform[0].Line3b_Unit[2]”] = items1[0];





I wanted to check the “Petitioner” checkbox option, below is the logic I tried-didn’t work, where as if I select the “applicant” checkbox option it is working



List items = GetCheckBoxValues(doc, “form1[0].#subform[0].Line4_Checkbox[2]”);

doc.Form.XFA[“form1[0].#subform[0].Line4_Checkbox[2]”] = items[0];



Thanks for the support.

Hi there,


Thanks for your inquriy. Please note in checkbox group you need to assign value to first checkbox, it will check appropriate checkbox accordingly. Please check following code snippet, it will help you to accomplish the task.

…

List<string> items = GetCheckBoxValues(doc, "form1[0].#subform[0].Line4_Checkbox[2]");

doc.Form.XFA["form1[0].#subform[0].Line4_Checkbox[0]"] = items[0];

//List items = GetCheckBoxValues(doc, "form1[0].#subform[0].Line3b_Unit[2]");

//doc.Form.XFA["form1[0].#subform[0].Line3b_Unit[0]"] = items[0];

//List items = GetCheckBoxValues(doc, "form1[0].#subform[1].Line12b_Unit[2]");

//doc.Form.XFA["form1[0].#subform[1].Line12b_Unit[0]"] = items[0];

.....
