Hi tpathan,

Use WebBrowser control to open the PDF. Refer following code.

Code

private void Form1_Load(object sender, EventArgs e)
{
    webBrowser1.IsWebBrowserContextMenuEnabled = false;
    webBrowser1.AllowWebBrowserDrop = false;
    webBrowser1.Navigate(@"D:\Files\Sample.pdf");
}

VB.Net

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    webBrowser1.IsWebBrowserContextMenuEnabled = False
    webBrowser1.AllowWebBrowserDrop = False
    webBrowser1.Navigate("D:\Files\Sample.pdf")
End Sub
