Here is my guess at what you're looking for:

//Assume that textbox1 has folder path

 OpenFileDialog openFileDialog = new OpenFileDialog();
                    openFileDialog.Multiselect = true;
                    openFileDialog.Filter = "Text files (*.txt)|*.txt|All files (*.*)|*.*";
                    openFileDialog.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
                    if(openFileDialog.ShowDialog() == true)
                    {
                            foreach(string filename in openFileDialog.FileNames)
                                    datagrid.Items.Add(Path.GetFileName(filename));
                    }
