Hi Aarron345,

Based on my experience, there are two options to make the DataGridViewButtonCell invisible.

One way is that we can custom paint the cell. Since the button inside a DataGridViewButtonCell is not an actual button, it is painted like a button, we can paint particular cell to make it looks like a common cell by handling the CellPainting event. Please check the following link for details.

The other way is very tricky. We can change the DataGridViewButtonCell to DataGridViewTextBoxCell to hide the Button. Here is a sample for your information.

Code Snippet

public partial class Form17 : Form

{

public Form17()

{

InitializeComponent();

}

private void Form17_Load(object sender, EventArgs e)

{

DataTable dt = new DataTable();

dt.Columns.Add("id");

dt.Columns.Add("item");

for (int i = 0; i < 50; i++)

{

dt.Rows.Add(i, "item" + i);

}

dt.AcceptChanges();

DataGridViewButtonColumn btnColumn = new DataGridViewButtonColumn();

btnColumn.DataPropertyName = "id";

btnColumn.Width = 100;

btnColumn.ReadOnly = true;

this.dataGridView1.Columns.Add(btnColumn);

this.dataGridView1.DataSource = dt;

foreach (DataGridViewRow dr in this.dataGridView1.Rows)

{

if (dr.Cells[0].Value != null)

{

int i;

if ((int.TryParse(dr.Cells[0].Value.ToString(),out i)))

{

if (i % 2 == 0)

{

DataGridViewTextBoxCell txtcell = new DataGridViewTextBoxCell();

dr.Cells[0] = txtcell;

}

Best regards.
