datagridview コンボ ボックスの内容を更新しようとすると、次の行で SetCurrentCellAddressCore 関数が再入可能に呼び出されるため、Operation is not valid がスローされます。
どうすればこの問題を解決できますか?? THX
private void treeGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)

try
{
if (e.Control.GetType() == new DataGridViewComboBoxEditingControl().GetType())
{
if ((cboEditor != null) && (cboEditor_EventHandler != null))
{
cboEditor.SelectedIndexChanged -= cboEditor_EventHandler;
}
cboEditor = (DataGridViewComboBoxEditingControl)e.Control;
cboEditor.SelectedIndexChanged += cboEditor_EventHandler;
if (this.treeGridView1.SelectedCells.Count > 0 &&
this.treeGridView1.SelectedCells[0].ColumnIndex == (int)Parameters.eColumn.valueBySelectionColumn)

break;
