Hello,
I try to set the visibility property /(button.Visibility =
PushbuttonField.VISIBLE_BUT_DOES_NOT_PRINT;)/. It works fine, but sometimes
few users click more than once, then the form is send and the button appears
on the PDF document.
I want to set the button to disabled after the click-event using JavaScript
(/submit.SetAdditionalActions (PdfName.D, PdfAction.JavaScript
("this.getField ('Submit'). Disabled = true ));", writer));/).
Any ideas?
This is the source code:
private static PdfFormField GetPushbuttonField(PdfWriter writer, Rectangle
box, string fieldName, string text, string submitUrl)
{
PushbuttonField button = new PushbuttonField(writer, box,
fieldName);
button.Text = text;
button.BackgroundColor = new
Color(System.Drawing.Color.FromKnownColor(System.Drawing.KnownColor.ButtonFace).ToArgb());
button.BorderStyle = PdfBorderDictionary.STYLE_BEVELED;
button.FontSize = 12;
button.BorderColor = new
Color(System.Drawing.Color.FromKnownColor(System.Drawing.KnownColor.ButtonHighlight).ToArgb());
button.Visibility = PushbuttonField.VISIBLE_BUT_DOES_NOT_PRINT;
PdfFormField submit = button.Field;
submit.Action = PdfAction.CreateSubmitForm(submitUrl, null,
PdfAction.SUBMIT_XFDF);
if (fieldName == "Submit")
{
submit.SetAdditionalActions(PdfName.D,
PdfAction.JavaScript("this.getField('Submit').disabled = true));", writer));
}
return submit;
}
