Although there is no RowNumber and ColumnNumber property available for DataGridView, you can use objects of DataGridViewCellEventArgs to get the Current row number and current column number as follows:
 
private void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e)
    {
        int columnIndex = e.ColumnIndex;
        int rowIndex = e.RowIndex;
    }
This will work only between any cell related event.
 
And if you want to rows according to index number you can use the following code
 
DataGridViewRow[] rows = new DataGridViewRow[dataGridView1.Rows.Count];
 
        for (int i = 0; i < dataGridView1.Rows.Count; i++)
        {
            rows[i] = dataGridView1.Rows[dataGridView1.Rows.IndexOf(dataGridView1.Rows[i])];
        }

dataGrid1 in your code has type System.Windows.Forms.DataGridViewCell but properties RowNumber and ColumnNumber belongs to class System.Windows.Forms.DataGridCell. So you should use object of DataGridCell class or use properties ColumnIndex and RowIndex which belongs to DataGridViewCell class.

A quick glance at the documentation[^] shows that System.Windows.Forms.DataGridViewCell does not contain a property by the name of RowNumber, or indeed ColumnNumber. Which is what the error message and red line are clearly explaining to you.
