DevExpress是非常主流的.NET控件，眼下全世界和中國都用非常多用戶使用，只是因為是英文版，初次接觸的同學可能會認為困難。這裏就總結DevExpress常見的10個使用技巧。

1.TextEditor(barEditItem)取文本

string editValue = barEditItem1.EditValue.ToString(); //錯誤，返回null

string editValue = ((DevExpress.XtraEditors.TextEdit)barEditItem).EditValue.ToString(); //精確，返回文本框內容 DevExpress使用技巧

2.ComboBoxEdit(barEditItem)加入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

//加入Page
DevExpress.XtraBars.Ribbon.RibbonPage ribbonPage = new RibbonPage();
ribbonControl.Pages.Add(ribbonPage);
//加入Group
DevExpress.XtraBars.Ribbon.RibbonPageGroup ribbonPageGroup = new RibbonPageGroup();
ribbonPage.Groups.Add(ribbonPageGroup);
//加入Button
DevExpress.XtraBars.BarButtonItem barButtonItem = new BarButtonItem();
ribbonPageGroup.ItemLinks.Add(barButtonItem);
//加入barSubItem
DevExpress.XtraBars.BarSubItem barSubItem = new BarSubItem();
ribbonPageGroup.ItemLinks.Add(barSubItem);
//barSubItem下加入Button
barSubItem.AddItem(barButtonItem);


//神秘的刪除Page問題（ DevExpress使用技巧）
while (this.ribbonControl.Pages.Count > 0)
{
ribbonControl.Pages.Remove(ribbonControl.Pages[0]); //調試正常。運轉報異常
}
while (this.ribbonControl.Pages.Count > 0)
{
ribbonControl.SelectedPage = ribbonControl.Pages[0];
ribbonControl.Pages.Remove(ribbonControl.SelectedPage); //運轉正常
}
//遏止F10鍵Tips （DevExpress使用技巧）
ribbonControl.Manager.UseF10KeyForMenu = false;
//DXbutton
ApplicationIcon屬性修改圖標
右鍵 Add ApplicationMenu 加入evExpress.XtraBars.Ribbon.ApplicationMenu5.HitInfo

//在Tab頁上點擊右鍵的工作響應（DevExpress使用技巧）
void xtraTabbedMdiManager_Event(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Right && ActiveMdiChild != null)
{
DevExpress.XtraTab.ViewInfo.BaseTabHitInfo hInfo = xtraTabbedMdiManager.CalcHitInfo(e.Location);
//右鍵點擊位置：在Page上且不在封閉button內
if (hInfo.IsValid && hInfo.Page != null && !hInfo.InPageCloseButton)
{
this.popupMenu.ShowPopup(Control.MousePosition);//在鼠標位置彈出，而不是e.Location
}
}
}
//在ribbon上點擊右鍵的工作響應
private void ribbonControl1_ShowCustomizationMenu(object sender, RibbonCustomizationMenuEventArgs e)
{
//禁掉原系統右鍵菜單
e.ShowCustomizationMenu = false;
//右鍵位置：在barButtonItem上
if (e.HitInfo != null
&& e.HitInfo.InItem
&& e.HitInfo.Item.Item is BarButtonItem)
{
this.popupMenu.ShowPopup(Control.MousePosition);
}
//右鍵位置：在barSubItem中的barButtonItem上
else if (e.Link != null
&& e.Link.Item != null
&& e.Link.Item is BarButtonItem)
{
this.popupMenu.ShowPopup(Control.MousePosition);
}
}

6.皮膚

//加入皮膚軌範集後註冊皮膚（ DevExpress使用技巧）
DevExpress.UserSkins.OfficeSkins.Register();
DevExpress.UserSkins.BonusSkins.Register();
//設置皮膚
DevExpress.LookAndFeel.UserLookAndFeel.Default.SetSkinStyle("Liquid Sky"); //若皮膚稱號錯誤則按系統默許設置（第一個皮膚）
//GalleryFilterMenuPopup工作設置彈出選擇菜單的“All Groups”為中文
private void rgbiSkins_GalleryFilterMenuPopup(object sender, GalleryFilterMenuEventArgs e)
{
e.FilterMenu.ItemLinks[n].Caption = "一切皮膚"; //n=分組數+1
}
//GalleryInitDropDownGallery工作設置彈出皮膚列表的表頭“ALL Groups”為中文
private void rgbiSkins_GalleryInitDropDownGallery(object sender, InplaceGalleryEventArgs e)
{
e.PopupGallery.FilterCaption = "一切皮膚";
}

7.dockManager

將視圖的狀況信息保管到xml文件
dockManager1.SaveLayoutToXml("..\\UserConfig\\ViewInfo.xml");
導出xml中保管的狀況信息
dockManager1.RestoreLayoutFromXml("..\\UserConfig\\ViewInfo.xml");

8.barManager

設置bar的字體與系統字體
barAndDockingController1.AppearancesBar.ItemsFont = new Font(this.Font.FontFamily, currentFontSize);

9.設置系統字體

DevExpress.Utils.AppearanceObject.DefaultFont = new Font(this.Font.FontFamily, currentFontSize);

10.treeView

為tree節點加右鍵菜單並選中該節點
private void treeList1_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Right)
{
DevExpress.XtraTreeList.TreeListHitInfo hi = treeList1.CalcHitInfo(e.Location);
if (hi.Node != null && hi.Node.ImageIndex == 5) //葉子節點的ImageIndex == 5
{
TreeListNode node = treeList1.FindNodeByID(hi.Node.Id);
treeList1.FocusedNode = node;

this.popupMenu1.ShowPopup(MousePosition);
}
}
}
