How do I populate a datagridview with data from XML file whose path is in items of listbox

private void ReadDropperScheduleFiles()
        {
            string folderPath = Directory.GetCurrentDirectory() + @"\" + "Libraries";
            string subfolder1 = folderPath + @"\" + "Dropper Schedule";
            string subfolder2 = folderPath + @"\" + "Support Schedule";

            lbxDropperLibrary.Items.Clear();
            try
            {
                string[] folder1 = Directory.GetFiles(subfolder1);
                string[] folder2 = Directory.GetFiles(subfolder2);

                foreach (string file1 in folder1)
                {
                    lbxDropperLibrary.Items.Add(Path.GetFileName(file1));
                }
                foreach (string file2 in folder2)
                {
                    lbxSupportLibrary.Items.Add(Path.GetFileName(file2));
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show("error " + ex.Message);
            }
