There are two possibilities here, one ugly and one from MSDN. The Ugly: Add a button to your DGV at runtime Do the following: - Add an unbound DataGridViewTextBoxColumn to your DGV. Note it's index value in your DGV; this is where you'll put your button. - Use your DGV's CellFormatting event like so: <pre><code> private void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e) { if (e.ColumnIndex == 0) { // Assumes column 0 has the data that determines if a button should be displayed. if (e.Value.ToString() == "bob") { // Test if a button should be displayed on row. // Create a Button and add it to our DGV. Button cellButton = new Button(); // Do something to identify which row's button was clicked. Here I'm just storing the row index. cellButton.Tag = e.RowIndex; cellButton.Text = "Hello bob"; cellButton.Click += new EventHandler(cellButton_Click); dataGridView1.Controls.Add(cellButton); // Your ugly button column is shown here as having an index value of 3. Rectangle cell = this.dataGridView1.GetCellDisplayRectangle(3, e.RowIndex, true); cellButton.Location = cell.Location; } } } </code></pre> When a user clicks the button the cellButton_Click event will fire. Here's some test code: <pre><code> void cellButton_Click(object sender, EventArgs e) { Console.WriteLine("Hello from row: {0}", ((Button) sender).Tag); } </code></pre> As you can see this isn't very refined. I based it on an even uglier sample I found. I'm sure you can modify it to suit your needs. From MSDN: Roll your own (extend) DataGridViewButtonColumn that conditionally displays a disabled button. For this option see <a href="http://msdn.microsoft.com/en-us/library/ms171619%28VS.90%29.aspx" rel="nofollow">How to: Disable Buttons in a Button Column in the Windows Forms DataGridView Control</a> Of course this option doesn't actually remove any buttons, only conditionally disables them. For your application however, this might be better.

Guidance

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.
