title: Change value in DataGridView directly
body: <p>How can I change the value from all cells in <code>DataGridView</code> Windows Forms? I want to change directly in Windows Forms, like typing directly in the cell</p>
  
  <p>I have a table like:</p>
  
  <pre><code>AA    BB    CC
  --------------
  1     aa    ac
  2     bb    fd// I type here and change the value to kk
  </code></pre>
  
  <p>Code:</p>
  
  <pre><code>DataGridViewTextBoxColumn AA= new DataGridViewTextBoxColumn();
  MsgIDHex.HeaderText = "AA";
  MsgIDHex.DataPropertyName = "AA";
  DataGridViewTextBoxColumn BB= new DataGridViewTextBoxColumn();
  MsgIDHex.HeaderText = "BB";
  MsgIDHex.DataPropertyName = "BB";
  DataGridViewTextBoxColumn CC= new DataGridViewTextBoxColumn();
  MsgIDHex.HeaderText = "CC";
  MsgIDHex.DataPropertyName = "CC;
  dataGridView1.DataSource = result;
  dataGridView1.Columns.AddRange(AA, BB, CC};
  </code></pre>
  
  <p>Should I do something with <code>DataGridViewTextBoxEditingControl</code>?</p>
