This quick start will guide you through the steps of adding FlexViewer control to the application, binding it with a document source, i.e., GcPdf, and loading the PDF in the FlexViewer control.

To achieve it, follow these steps:

1. Add FlexViewer control
2. Load the PDF document
3. Run the Project

The following image shows how the FlexViewer control appears after completing the steps above.

Step 1: Add FlexViewer control

In the Solution Explorer, open the activity_main.axml file from the layout folder inside the Resources folder and replace its code with the following code:

<c1.android.viewer.FlexViewer
      android:id="@+id/FlexViewer"
      android:layout_width="match_parent"
      android:layout_height="match_parent"/>

Alternatively, you can drag a FlexPie control from the Toolbox within the custom control tab onto your layout surface in designer mode.

Step 2: Load the PDF document

Load the PDF document in the FlexViewer control using the following code. In this example, we have added a PDF document to the Assets folder to load it in the viewer.

//#region load
var flexViewer = FindViewById<FlexViewer>(Resource.Id.FlexViewer);

using (var stream = Assets.Open("DefaultDocument.pdf", Android.Content.Res.Access.Streaming))
{
    using (var sr = new StreamReader(stream))
    {
        memoryStream = new MemoryStream();
        sr.BaseStream.CopyTo(memoryStream);
        flexViewer.LoadDocument(memoryStream);
    }
}

Step 3: Run the Project

Press F5 to run the application.
