Dev技巧记录

DevExpress是DevExpress公司出品，非常主流的.NET控件，目前全世界和中国都用很多用户使用，不过由于是英文版，初次接触的同学可能会觉得困难，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)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.RibbonPageribbonPage = new RibbonPage(); ribbonControl.Pages.Add(ribbonPage); //添加Group

DevExpress.XtraBars.Ribbon.RibbonPageGroupribbonPageGroup = new RibbonPageGroup();

ribbonPage.Groups.Add(ribbonPageGroup); //添加Button

DevExpress.XtraBars.BarButtonItembarButtonItem = new BarButtonItem(); ribbonPageGroup.ItemLinks.Add(barButtonItem); //添加barSubItem

DevExpress.XtraBars.BarSubItembarSubItem = new BarSubItem(); ribbonPageGroup.ItemLinks.Add(barSubItem); //barSubItem下添加Button

barSubItem.AddItem(barButtonItem);

//奇异的删除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; //DX按钮

ApplicationIcon属性改动图标

右键 Add ApplicationMenu 添加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.BaseTabHitInfohInfo = 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 } } }

//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

//添加皮肤轨范集后注册皮肤（ 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); } } }
