To load and view a PDF document using the PdfDocumentSource component and FlexViewer control, follow the steps below:

1. Create a new WinForms application.
2. Navigate to the Toolbox, drag and drop FlexViewer control on the form. Adjust the position and size of FlexViewer according to your requirement.
3. Drag and drop PdfDocumentSource component on the form. It appears in the form's component tray.
4. In Properties Window, go to the FlexViewer's properties, and assign the name of the PdfDocumentSource component to the DocumentSource property value field. This property gets the PDF document source shown by FlexViewer.
5. Select PdfDocumentSource component and navigate to its properties in the Properties window. Add the full path of the PDF document to the DocumentLocation property. This fetches the location of the document in the PdfDocumentSource component .
