Namespace: DevExpress.Pdf
Assembly: DevExpress.Pdf.v24.2.Core.dll
NuGet Package: DevExpress.Pdf.Core
#Declaration
public void AddWidget(
int pageNumber,
PdfRectangle rectangle
)
#Parameters
Name | Type | Description |
---|---|---|
page |
Int32 | The number of a page to which to add the widget annotation (starting with 1). |
rectangle | Pdf |
The page rectangle where the widget annotation should be added. |
#Remarks
A widget annotation contains form field display properties. One field can be related to multiple widget annotations. When you create a form field, the widget annotation is created automatically. Call the AddWidget method and pass the page number as the method parameter to create an additional widget on a separate page.
The code sample below creates a list box with one widget annotation on the first page, and another widget on the second page:
using DevExpress.Pdf;
using System.Globalization;
using (PdfDocumentProcessor processor = new PdfDocumentProcessor())
{
// Load a document
processor.LoadDocument("..\\..\\Document.pdf");
// Create a list box field
PdfAcroFormListBoxField listBox =
new PdfAcroFormListBoxField("Language", 1, new PdfRectangle(230, 595, 330, 615));
// Specify list box color and font size
listBox.Appearance.BackgroundColor = new PdfRGBColor(0.8, 0.5, 0.3);
listBox.Appearance.FontSize = 12;
// Add values to the list box
var allCultures = CultureInfo.GetCultures(CultureTypes.NeutralCultures);
foreach (var item in allCultures)
{
if (item!= null)
{
listBox.AddValue(item.DisplayName);
}
}
listBox.MultiSelect = false;
// Add a widget annotation on the second page
listBox.AddWidget(2, new PdfRectangle(230, 595, 330, 615));
// Add a form field
processor.AddFormFields(textBox, radioGroup, listBox);
// Save the result
processor.SaveDocument("..\\..\\Result.pdf");
}
