		{
			try {
				if (System.IO.Directory.Exists(SelectedPath)) {
				String[] files = System.IO.Directory.GetFiles(SelectedPath);
					DataGridViewCheckBoxColumn CheckBoxColumn = new DataGridViewCheckBoxColumn();
					DataGridViewTextBoxColumn FileNameColumn = new DataGridViewTextBoxColumn();                
					CheckBoxColumn.HeaderText = "Check Items";
					FileNameColumn.HeaderText = "File Name";                
					dataGridView1.Columns.Clear();
					dataGridView1.Rows.Clear();               
					dataGridView1.Columns.Add(CheckBoxColumn);
					dataGridView1.Columns.Add(FileNameColumn);   
					dataGridView1.Columns[1].ReadOnly = true;				  				            
					for (int i = 0; i < files.Length; i++) {
				   
					   dataGridView1.Rows.Add(false, files[i]);
					}     									
				}					
			} catch (Exception e) {
				MessageBox.Show(e.Message);
			}
