openFileDialog1 pops up when I try to browse for a file using C# FileDialog

All,

Please note with the following code that for some reason puts openFileDialog1 as the filename - so if someone were to click Open it tries to say the name they are selecting is openFileDialog1.  I find that to be annoying - is there anything in the following code that I'm using incorrectly in the syntax causing this?

Please note result in attachment!

if (rbSingle.Checked == true)
            {
                string defaultpath = txtPath.Text;
                string newfile = "";



                fdPath.InitialDirectory = defaultpath;
                DialogResult result = this.fdPath.ShowDialog();
                if (result == DialogResult.OK)
                {
                    newfile = fdPath.FileName;

                    if (newfile != "openFileDialog1")
                            {
                                ShowMyMessageBox(@"File must be a PDF");
                            }

                    if (newfile.Substring(0, 1) != "C")
                    {
                        ShowMyMessageBox(@"File must be located locally on your C:\drive");
                    }
                    else
                    {
                        //fileName.Substring(fileName.Length - 4)
                        if (newfile.Substring(newfile.Length - 4) != ".pdf")
                        {
                            
                            
                        }
                        else
                        {
                            txtPath.Text = newfile;
                            this.Height = 516;
                        }

                    }

                }

            }
