My requirement is need to set readonly true and set grey color for the checkbox for the country has Germany as like below.

Not like below

I need to set color for checkbox only not for datagridview cell.

Is anyone have idea for this?

Answer 1

You can achieve that by setting checkbox's property: 'Enabled' as false. by that way, the checkbox cannot be clicked and its color changes automatically to grey. Example

Answer 2

Given the answer here and slightly change it

private void DataGridView1_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e)
{
    var value = Convert.ToString(dataGridView1.Rows[e.RowIndex].Cells[2].Value);
    DataGridViewCell cell = dataGridView1.Rows[e.RowIndex].Cells[0];

    if (value == "Germany" && cell.ReadOnly != true)
    {
        DataGridViewCheckBoxCell chkCell = cell as DataGridViewCheckBoxCell;
        chkCell.Value = false;
        chkCell.FlatStyle = FlatStyle.Flat;
        chkCell.Style.ForeColor = Color.DarkGray;
        cell.ReadOnly = true;
    }
}

Result
