I 've find out this solution. It uses an external 'true' DropDownComboBox. ..... this.cboDescrizione.Leave += new System.EventHandler(this.cboDescrizioneLeave); ..... this.grdWPreventivo.CellEnter += new System.Windows.Forms.DataGridViewCellEventHandler( this.GrdWPreventivoCellContentClick); this.grdWPreventivo.CellContentClick += new System.Windows.Forms.DataGridViewCellEventHandler( this.GrdWPreventivoCellContentClick); ..... ..... private void GrdWPreventivoCellContentClick(object sender System.Windows.Forms.DataGridViewCellEventArgs e) { DataGridView grd = this.grdWPreventivo; Rectangle rect = grd.GetCellDisplayRectangle(e.ColumnIndex e.RowIndex false); if (e.ColumnIndex==0) { RigaCorrente = e.RowIndex; blEditing = true; // ------------------------------------- // Set combo absolute position // ------------------------------------- cboDescrizione.Left = rect.X + grd.Left; cboDescrizione.Top = rect.Y + grd.Top; cboDescrizione.BringToFront(); } else blEditing = false; // --------------------------------------- // Set combo visible so can receive focus // --------------------------------------- cboDescrizione.Visible = blEditing; // ----------------------------------------- // Can combo receive Focus() ? // ----------------------------------------- if (blEditing) cboDescrizione.Focus(); } private void cboDescrizioneLeave(object sender System.EventArgs e) { // ----------------------------------- // Stop editing. Start CellValidating. // ----------------------------------- string valore = cboDescrizione.Text; blEditing = false; this.grdWPreventivo.Rows[RigaCorrente].Cells[0].Value = valore; cboDescrizione.SendToBack(); cboDescrizione.Visible = false ; int i = this.cboDescrizione.FindString(cboDescrizione.Text ); if (i==-1) cboDescrizione.Items.Add(cboDescrizione.Text); } Bye.
