是非常主流的.NET控件，眼下全世界和中国都用非常多用户使用，只是因为是英文版，初次接触的同学可能会认为困难。这里就总结DevExpress常见的10个使用技巧。

1.TextEditor(barEditItem)取文本 

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

string editValue = ((DevExpress.XtraEditors.TextEdit)barEditItem).EditValue.ToString();    //精确，返回文本框内容 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);

//神秘的删除Page问题（ DevExpress使用技巧）

while (this.ribbonControl.Pages.Count > 0)

{

ribbonControl.Pages.Remove(ribbonControl.Pages[0]);    //调试正常。运转报异常

}

while (this.ribbonControl.Pages.Count > 0)

{

ribbonControl.SelectedPage = ribbonControl.Pages[0];

ribbonControl.Pages.Remove(ribbonControl.SelectedPage); //运转正常

}

//遏止F10键Tips （DevExpress使用技巧）

ribbonControl.Manager.UseF10KeyForMenu = false;

//DXbutton

ApplicationIcon属性修改图标

右键 Add ApplicationMenu 加入evExpress.XtraBars.Ribbon.ApplicationMenu5.HitInfo 

//在Tab页上点击右键的工作响应（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);

//右键点击位置：在Page上且不在封闭button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

}

}

}

//在ribbon上点击右键的工作响应

private void ribbonControl1_ShowCustomizationMenu(object sender, RibbonCustomizationMenuEventArgs e)

{

//禁掉原系统右键菜单

e.ShowCustomizationMenu = false;

//右键位置：在barButtonItem上

if (e.HitInfo != null 

&& e.HitInfo.InItem

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

{

this.popupMenu.ShowPopup(Control.MousePosition);

}

//右键位置：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.皮肤 

//加入皮肤轨范集后注冊皮肤（ DevExpress使用技巧）

DevExpress.UserSkins.OfficeSkins.Register();

DevExpress.UserSkins.BonusSkins.Register();

//设置皮肤

DevExpress.LookAndFeel.UserLookAndFeel.Default.SetSkinStyle("Liquid Sky");    //若皮肤称号错误则按系统默许设置（第一个皮肤）

//GalleryFilterMenuPopup工作设置弹出选择菜单的“All Groups”为中文

private void rgbiSkins_GalleryFilterMenuPopup(object sender, GalleryFilterMenuEventArgs e)

{

e.FilterMenu.ItemLinks[n].Caption = "一切皮肤";    //n=分组数+1

}

//GalleryInitDropDownGallery工作设置弹出皮肤列表的表头“ALL Groups”为中文

private void rgbiSkins_GalleryInitDropDownGallery(object sender, InplaceGalleryEventArgs e)

{

e.PopupGallery.FilterCaption = "一切皮肤";

}

7.dockManager 

将视图的状况信息保管到xml文件

dockManager1.SaveLayoutToXml("..\\UserConfig\\ViewInfo.xml");

导出xml中保管的状况信息

dockManager1.RestoreLayoutFromXml("..\\UserConfig\\ViewInfo.xml");

8.barManager 

设置bar的字体与系统字体

barAndDockingController1.AppearancesBar.ItemsFont = new Font(this.Font.FontFamily, currentFontSize);

9.设置系统字体 

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

10.treeView 

为tree节点加右键菜单并选中该节点

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) //叶子节点的ImageIndex == 5

{

TreeListNode node = treeList1.FindNodeByID(hi.Node.Id);

treeList1.FocusedNode = node;

this.popupMenu1.ShowPopup(MousePosition);

}

}

}
