You need to do it by adding your own code. The class being designed does not have a property for the runtime behavior you need.

Hi damu maddy,

As @Sheng Jiang said, there is no built-in property to support this behavior. But we can implement by our own code.

When you change a cell’s value, it cause CellValueChanged event. We can set ReadOnly property to a row, a column or a cell. Try something like the following:

private void Form1_Load(object sender, EventArgs e)

DataTable dt1 = new DataTable("dt1");

"tag");

for (int i = 0; i < 10; i++)

"aa");

DataGridViewCheckBoxColumn checkBoxColumn = new DataGridViewCheckBoxColumn();

this.dataGridView1.Columns.Insert(0, checkBoxColumn);

this.dataGridView1.CellValueChanged += new DataGridViewCellEventHandler(dataGridView1_CellValueChanged);

void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e)

if (e.ColumnIndex == 0)

// if checked

if (dataGridView1.CurrentCell.Value.ToString() == "True")

// make the row readonly except the first cell(check box)

true;

false;

else // unchecked

false;

If you have any other questions, please feel free to ask.

Best regards,

Ling Wang
