Get FieldLimit

I understand how to SetFieldLimit, but I would like to get the value before I change it.

Is this possible?

Hi Diane,

Thanks for contacting support. In case you need to get the field limit/width, you may consider using following code snippet.

C#

// open document
Document pdfDocument = new Document("input.pdf");

// get a field
TextBoxField textBoxField = pdfDocument.Form["textbox1"] as TextBoxField;

// get field value
Console.WriteLine("PartialName : {0} ", textBoxField.PartialName);
Console.WriteLine("Value : {0} ", textBoxField.Value, textBoxField.Value);
Console.WriteLine("Width : {0} ", textBoxField.Width);

Is that width the physical width of the field on the document (measurement) or the number of characters allowed within the field?

I need the number of characters that are allowed to be entered a textbox field.

Thanks,
Diane Asberry

Hi Diane,

Sorry for the delayed response.

The above stated code snippet returns the width of field in terms of measurement (object width over PDF file).

Hi Diane,

Thanks for your feedback. Please check the following code snippet to get the maximum field limit. Hopefully, it will help you to accomplish the task.

// Adding Field with limit
Aspose.Pdf.Facades.FormEditor form = new Aspose.Pdf.Facades.FormEditor();
form.BindPdf("input.pdf");
form.SetFieldLimit("textbox1", 15);
form.Save("output.pdf");

// Getting maximum field limit using DOM
Document doc = new Document("output.pdf");
Console.WriteLine("Limit: " + (doc.Form["textbox1"] as TextBoxField).MaxLen);

// Getting maximum field limit using Facades
Aspose.Pdf.Facades.Form form = new Aspose.Pdf.Facades.Form();
form.BindPdf("output.pdf");
Console.WriteLine("Limit: " + form.GetFieldLimit("textbox1"));

Please feel free to contact us for any further assistance.

Best Regards,
