DevExpress控件使用使用技巧小结
零零散散的先总结一下吧
1.TextEditor(barEditItem)取文本
string editValue = barEditItem1.EditValue.ToString(); //错误，返回null
string editValue =
((DevExpress.XtraEditors.TextEdit)barEditItem).EditValue.ToString(); //正确，返回文本框内容boBoxEdit(barEditItem)添加Item
string item = "comboboxItem1";
((DevExpress.XtraEditors.Repository.RepositoryItemComboBox)this.barEd itItem.Edit).Items.Add(item);boBoxEdit(barEditItem)取文本
string itemValue = this.barEditItem.EditValue.ToString();4.Ribbon控件//添加Page
DevExpress.XtraBars.Ribbon.RibbonPage ribbonPage = new RibbonPage(); ribbonControl.Pages.Add(ribbonPage);
//添加Group
DevExpress.XtraBars.Ribbon.RibbonPageGroup ribbonPageGroup = new RibbonPageGroup();
ribbonPage.Groups.Add(ribbonPageGroup);
//添加Button
DevExpress.XtraBars.BarButtonItem barButtonItem = new BarButtonItem(); ribbonPageGroup.ItemLinks.Add(barButtonItem);
//添加barSubItem
DevExpress.XtraBars.BarSubItem barSubItem = new BarSubItem(); ribbonPageGroup.ItemLinks.Add(barSubItem);
//barSubItem下添加Button
barSubItem.AddItem(barButtonItem);
//奇怪的删除Page问题
while (this.ribbonControl.Pages.Count > 0)
{
ribbonControl.Pages.Remove(ribbonControl.Pages[0]); //调试正常，运行报异常
}
while (this.ribbonControl.Pages.Count > 0)
{
ribbonControl.SelectedPage = ribbonControl.Pages[0];
ribbonControl.Pages.Remove(ribbonControl.SelectedPage); //运行正常
}
//禁止F10键Tips
eF10KeyForMenu = false;
//DX按钮
ApplicationIcon属性改变图标
右键 Add ApplicationMenu 添加
evExpress.XtraBars.Ribbon.ApplicationMenu5.HitInfo
//在Tab页上点击右键的事件响应
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上且不在关闭按钮内
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上点击右键的事件响应
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
//添加皮肤程序集后注册皮肤
erSkins.OfficeSkins.Register();
erSkins.BonusSkins.Register();
//设置皮肤
erLookAndFeel.Default.SetSkinStyle("Liquid Sky"); //若皮肤名称错误则按系统默认设置（第一个皮肤）
//GalleryFilterMenuPopup事件设置弹出筛选菜单的“All Groups”为中文private void rgbiSkins_GalleryFilterMenuPopup(object sender, GalleryFilterMenuEventArgs e)
{
e.FilterMenu.ItemLinks[n].Caption = "所有皮肤"; //n=分组数+1 }
//GalleryInitDropDownGallery事件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 = "所有皮肤";
}7.dockManager
将视图的状态信息保存到xml文件
dockManager1.SaveLayoutToXml("..\\UserConfig\\ViewInfo.xml");
导出xml中保存的状态信息
dockManager1.RestoreLayoutFromXml("..\\UserConfig\\ViewInfo.xml");8.b arManager
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); }
}
}。
