    WinExplorerView view = sender as WinExplorerView;
    if (e.Item.Name == "itemCheck") {
        view.SetRowCellValue((int)e.DataItem, view.ColumnSet.CheckBoxColumn, ((CheckContextButton)e.Item).Checked);

private void winExplorerView1_ContextButtonCustomize(object sender, WinExplorerViewContextButtonCustomizeEventArgs e) {
    WinExplorerView view = sender as WinExplorerView;
    if (e.Item.Name == "itemCheck") {
