Why opening a pdf from winform I can't highlight text? (normally I can)

When I open a PDF from Adobe Reader (normally) I can highlight text with no problems, but when I open the same pdf file from an Adobe Reader tool into a winform I can't highlight text.

I'm writing in c# VS2015 and here's my code to open the Pdf file into the winform:

 private void Form1_Load(object sender, EventArgs e)
    {
        OpenFileDialog dlg = new OpenFileDialog();
        dlg.Filter = "pdf files (*.pdf) |*.pdf;";
        dlg.ShowDialog();
        if (dlg.FileName != null)
        {
            axAcroPDF1.LoadFile(dlg.FileName);
        }
    }

Where did I make mistakes? It's a code mistake/forgetfulness or it's a conceptual mistake?

Solution

  • No possibility to do that: suggested by TheDanMan comment I checked the Ax Control Properties and I find out that I can't highlight text (the Ax Control properties are here).
