Display date now in the whole gridview column

Question

Hello Forum

Hello every one

Please Gentelman if you can help me to resolve this problem

I have this code  to do the whole column number 8 of DataGirdView1 in datetime type

For M As Integer = 0 To DataGridView1.Rows.Count - 1
        DataGridView1.Rows(M).Cells(8).Value = Date.Now
    Next

 But now i change DataGridView with GridControl .. but this code does not work correctly

For M As Integer = 0 To GridView1.RowCount - 1
       GridView1.GetRowCellValue(M).Columns(8) = Date.Now
   Next

 Thank you in advance for help

Cordially
