2.ComboBoxEdit(barEditItem)添加Item  

string item = "comboboxItem1"; 

((DevExpress.XtraEditors.Repository.RepositoryItemComboBox)this.barEditItem.Edit).Items.Add(item); 

3.ComboBoxEdit(barEditItem)取文本  

string itemValue = this.barEditItem.EditValue.ToString(); 

4.Ribbon控件  

//添加Page 

DevExpress.XtraBars.Ribbon.RibbonPage ribbonPage = new RibbonPage();

     { 

          DevExpress.XtraTab.ViewInfo.BaseTabHitInfo hInfo = xtraTabbedMdiManager.CalcHitInfo(e.Location); 

          //右键点击位置：在Page上且不在封闭按钮内 

          if (hInfo.IsValid && hInfo.Page != null && !hInfo.InPageCloseButton) 

          { 

               this.popupMenu.ShowPopup(Control.MousePosition);//在鼠标位置弹出，而不是e.Location

    //右键位置：在barButtonItem上 

    if (e.HitInfo != null  

     && e.HitInfo.InItem 

     && e.HitInfo.Item.Item is BarButtonItem) 

    {

                {
