Adding a checkboxcolumn to DataGridView, WinForm

Question

Enable Adding is false
Enable Editing is false
Enable Deleting is false
Enable Column Reordering is false

All those above settings applied I tried to see a check mark on checkboxcolumn when I click but fail, It does not appear my click actions on checkboxcolumn even I used below code.

private void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e)
    {
        if (e.ColumnIndex == 0)
        {
            dataGridView1.Columns[0].ReadOnly = false;
        }
    }

Answer 1

You cannot make only one column as readonly if datagridview on a whole is set as readonly (ie Enable editting to false )

So, firstly you need to set that to

dataGridView1.ReadOnly =false;

Next, you need to set all the columns in your code as readonly.

foreach (DataGridViewColumn dgvCol1 in dataGridView1.Columns)
{
     dgvCol1.ReadOnly = true;
}

Lastly, set the required column's readonly property ( in your case the checkbox column )
to false.

dataGridView1.Columns("ColumnName").ReadOnly = false;

I hope this solution is useful for you.
