One soltuion to this problem is to handle the CellBeginEdit event adn
cancel things if this particluar cell should be readonly.

//ReadOnlyColName0 is the name of the column you may want to be
readonly
//boolColName is the name of the column where you have your boolean
test value to check for readonly
void dataGridView1_CellBeginEdit(object sender,
DataGridViewCellCancelEventArgs e)
       {
           if (dataGridView1.Columns[e.ColumnIndex].Name ==
"ReadOnlyColName0")
           {
               object o = dataGridView1["boolColName",
e.RowIndex].Value;
               e.Cancel = o != null &&
Convert.ToBoolean(o);
           }
       }

Hi Patrik,

Based on my understanding, you'd like to make some cells in a column
editable and others non-editable and the problem is this does not open a
specific cell for editing but seems to open all cells in the column. If I'm
off base, please feel free to let me know.

It is possible to have some cells in a column to override the columns
ReadOnly property. As you have mentioned, we could set the ReadOnly
property of the cell to make it editable or non-editable.

You mentioned the AddRows event. Do you mean the RowsAdded event of the
DataGridView? The RowsAdded event is propriate when the user adds a new row
using the row for new records in the DataGridView. The
DataGridViewRowsAddedEventArgs.RowIndex value in the handler for this event
is equal to the index of the new location of the row for new records, which
is one greater than the row just added. However, when you add rows
programmatically, the RowInex value is the index of the first row added.

I suggest that you subscribe the RowPostPaint event of the DataGridView and
set the ReadOnly property of the cells you want in the event handler.

The following is a sample.

void dataGridView1_RowPostPaint(object sender,
DataGridViewRowPostPaintEventArgs e)
       {
           if (this.dataGridView1.Rows[e.RowIndex].Cells[0].Value != null)
           {
               if
(((int)this.dataGridView1.Rows[e.RowIndex].Cells[0].Value) % 2 == 0)
               {
                   this.dataGridView1.Rows[e.RowIndex].Cells[1].ReadOnly =
false;
               }
           }
       }

Hope this helps.
If you have any question, please feel free to let us know.

BTW, I will be on a long vacation from the next Monday to Friday. During my
leave, my team mates will follow up to you and it may not in time. Sorry
for the inconvenience it may bring to you!
