Hi,

You could do this:

        private void ultraGrid1_CellChange(object sender, CellEventArgs e)
        {
            if (e.Cell.Column.DataType == typeof(bool))
            {
                e.Cell.Row.Update();
            }
        }      

But this may not be ideal, because it will commit any changes in the entire row.

Another option would be to just get the new value of the cell inside the CellChange event and use it for whatever you need, without updating the data source.But to do that, you have to use the Text property of the cell.

        private void ultraGrid1_CellChange(object sender, CellEventArgs e)
        {
            if (e.Cell.Column.DataType == typeof(bool))
            {
                bool newValue = bool.Parse(e.Cell.Text);
                Debug.WriteLine(newValue);
            }
        }
