+### Add a view as custom stamps without using the toolbar
+
+You can create a custom stamp from any view, such as Button, Entry, Label, Image, or any other view, and add it to a PDF document. The following example explains how to create a custom stamp from a button view in the application and add it to a PDF document using the [AddAnnotation](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.PdfViewer.SfPdfViewer.html#Syncfusion_Maui_PdfViewer_SfPdfViewer_AddAnnotation_Syncfusion_Maui_PdfViewer_Annotation_) method of the [SfPdfViewer](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.PdfViewer.SfPdfViewer.html).

+
+    // Create a button to be used as the visual content of the stamp.
+    var button = new Button

+    Text = "Click Me",

+

 ## Edit the selected stamp
 
 You can edit the properties of the selected stamp annotation programmatically by accessing the selected annotation instance. The selected annotation instance may be obtained from the [AnnotationSelected](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.PdfViewer.SfPdfViewer.html#Syncfusion_Maui_PdfViewer_SfPdfViewer_AnnotationSelected) event.
