Youre trying to treat that ComboBox like it's the same one you drop on a form. It's not. That combo is buried under a DataGridViewComboBoxCell as the cell's Edit Control, which is buried under a DataGridViewComboBoxColumn. What do you think you need this for?? Under any normal circumstances, if your dataset/datatable, dgv is configured correctly, you would never need to handle this event.

If e.ColumnIndex = 0 Then indexcombo = CType(Me.dgvTipuriColoane.Rows(e.RowIndex).Cells(e.ColumnIndex), DataGridViewComboBoxCell).Items.IndexOf(Me.dgvTipuriColoane.Rows(e.RowIndex).Cells(e.ColumnIndex).Value.ToString) End If valoareCombo = Me.dgvTipuriColoane.Rows(e.RowIndex).Cells(e.ColumnIndex).Valuewhere the indexcombo is the index you choosed in combo. -

Your using an event that doesn't fire until the new value is commited to the cell. Is he looking for that?? Or is he looking to find out BEFORE the value is commited?? That's why I asked...
