Disabling Rows in DataGridView

[shalakasan]

Hi,
I am new to the forms world and have a silly doubt.

I have form with a DataGridview and an "Add" button. When the user
clicks on the add button, one row gets added to the datagrid.
Now I want that when the user hits the "Add" button, then new row
should be added and all the previous rows should be disabled for
selection/editing.

How can I disable previous rows for selection/editing?

Here is my sample code (just example..won't compile)

private void buttonAdd_Click(object sender, EventArgs e)
{
// Add new row
DataRow row;
row = diagnosticsTable.NewRow();
// Then add the new row to the collection.
row["DIAGNOSTIC_NAME"] = "AddDiagnosticsName";
row["DIAGNOSTIC_DESCRIPTION"] =
"AddDiagnosticsDescription";
row["SYSTEM_NAME"] = "Newsys";
diagnosticsTable.Rows.Add(row);

this.dataGridViewDiagnostic.CurrentCell =
this.dataGridViewDiagnostic[1, 0];
}

Thankyou...

Get the Collection of DataGridViewRows.

Then go through all rows and set the ReadOnly property to true.

following which you can add the new row

Thanks for your response.
Actually what I want is all the rows except the newly added row should
be greyed out.
Also, due you suggest any good tutorial/ sample on this?
