DevExpressV22:RepositoryItemComboBox的QueryPopUp事件无法动态加载数据项

经测试，表格中RepositoryItemComboBox的QueryPopUp事件无法动态加载数据项！

解决方案：必须使用 BeginInit / EndInit() 初始化组件！

C# Code:

private void OnCmbPaperNameProduce_QueryPopUp(object sender, CancelEventArgs e)
{
var rowSOs = gvDetail.GetObject<tb_SOs>();
var list = _BLL.GetSupplierProducePapers(rowSOs.SupplierCode, rowSOs.PaperName);

cmbPaperNameProduce.BeginInit();
cmbPaperNameProduce.Items.Clear();
cmbPaperNameProduce.Items.AddRange(list);
cmbPaperNameProduce.EndInit();

if (list.Count > 15)
cmbPaperNameProduce.DropDownRows = 15;
else
cmbPaperNameProduce.DropDownRows = list.Count;

cmbPaperNameProduce.DropDownItemHeight = 22;
}

C# Code:

cmbPaperNameProduce.TextEditStyle = TextEditStyles.DisableTextEditor;
cmbPaperNameProduce.QueryPopUp += OnCmbPaperNameProduce_QueryPopUp;
