    <p>Here is the demo I've just tried. It seems to work OK. The whole idea is <strong>You can't hide a particular cell in DataGridView</strong>. However you can make it hidden as a normal GUI engine will use when it wants to hide any control/element (I think so). You just customize it to paint the cell with the <code>BackgroundColor</code> of your <code>DataGridView</code>. Of course, to make it work, it's not such easy. Here is the code for you:</p> <pre><code>//First, you have to be sure the whole third column is Visible. //CellPainting event handler for your dataGridView1 private void dataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e) { if (e.ColumnIndex == 2)//This is the Column index you want to hide. { object o = e.RowIndex == -1 ? null : dataGridView1[e.ColumnIndex - 1,e.RowIndex].Value; if (o!=null &amp;&amp;!(bool)o || e.RowIndex == -1 || e.RowIndex == dataGridView1.RowCount - 1) { e.Graphics.FillRectangle(new SolidBrush(dataGridView1.BackgroundColor), e.CellBounds); if(e.RowIndex &gt; -1) dataGridView1[e.ColumnIndex, e.RowIndex].ReadOnly = true; e.Handled = true; } if (o != null &amp;&amp; (bool)o) { dataGridView1[e.ColumnIndex, e.RowIndex].ReadOnly = false; } } } //CellContentClick event handler for your dataGridView1 private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e) { UpdateThirdColumCell(e); } //CellContentDoubleClick event handler for your dataGridView1 private void dataGridView1_CellContentDoubleClick(object sender, DataGridViewCellEventArgs e) { UpdateThirdColumCell(e); } private void UpdateThirdColumCell(DataGridViewCellEventArgs e) { if (e.ColumnIndex == 1)//The column index of the CheckBox column { DataGridViewCheckBoxCell cell = (DataGridViewCheckBoxCell)dataGridView1[e.ColumnIndex, e.RowIndex]; cell.Value = cell.EditingCellFormattedValue; dataGridView1.Invalidate(); if ((bool)cell.Value) { dataGridView1.CurrentCell = dataGridView1[e.ColumnIndex + 1, e.RowIndex]; } } } //CellStateChanged event handler for your dataGridView1 private void dataGridView1_CellStateChanged(object sender, DataGridViewCellStateChangedEventArgs e) { if (e.Cell.ColumnIndex == 2 &amp;&amp; e.Cell.Selected) { dataGridView1.BeginEdit(false); } } </code></pre> <p>And that's all :)</p> <p><img src="https://i.stack.imgur.com/UZWWY.png" alt="enter image description here"></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.
