    <p>hi guys i am new to c# and i was making a text editor program using data grid view. The problem is when i open a text file to my data grid, then when i press save i get the error saying "Index was outside the bounds of the array". I included my code below. Any suggestions can be a big help for me. I included my code below. </p> <pre><code> // edit file button dataGridView1.Columns.Add("colname", "Question"); dataGridView1.Columns.Add("colname", "Answer 1"); dataGridView1.Columns.Add("colname", "Answer 2"); dataGridView1.Columns.Add("colname", "Answer 3"); dataGridView1.Columns.Add("colname", "Answer 4"); dataGridView1.Columns.Add("colname", "Correct Answer"); dataGridView1.Columns[5].ReadOnly = true; dataGridView1.Columns[5].DefaultCellStyle.BackColor = Color.DimGray; dataGridView1.AllowUserToAddRows = true; StreamReader sr = new StreamReader(fName); string Contents = sr.ReadToEnd(); string[] strArray = { Contents }; for (int r = 0; r &lt;= dataGridView1.Rows.Count - 1; r++) { for (int c = 0; c &lt;= dataGridView1.Columns.Count - 1; c++) { dataGridView1.Rows.Add(strArray[r].Split('|')); //getting the error here } } //save button private void button2_Click(object sender, EventArgs e) { //dataGridView1.AllowUserToAddRows = false; if (dataGridView1.Visible) { string fName = "C:\\Documents and Settings\\" + txtFileName.Text + ".txt"; System.IO.StreamWriter file = new System.IO.StreamWriter(fName); string sLine = ""; for (int r = 0; r &lt;= dataGridView1.Rows.Count - 1; r++) { for (int c = 0; c &lt;= dataGridView1.Columns.Count - 1; c++) { sLine = sLine + dataGridView1.Rows[r].Cells[c].Value; if (c != dataGridView1.Columns.Count - 1) { sLine = sLine + "|"; } } file.WriteLine(sLine); sLine = ""; } file.Close(); System.Windows.Forms.MessageBox.Show("Save Complete.", "Program Info", MessageBoxButtons.OK, MessageBoxIcon.Information); dataGridView1.DataSource = ""; dataGridView1.Visible = false; } else { string cap = "Confirmation"; string message = "Nothing to save"; MessageBoxButtons Btn2 = MessageBoxButtons.OK; MessageBox.Show(message, cap, Btn2); } } </code></pre> <p>Thanks again for the help</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
