devexpress使用的十个技巧
DevExpress的10个使用技巧
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
https://www.360docs.net/doc/254983463.html,boBoxEdit(barEditItem)添加Item
string item = "comboboxItem1";
((DevExpress.XtraEditors.Repository.RepositoryItemComboBox)this.barEditIte m.Edit).Items.Add(item);
https://www.360docs.net/doc/254983463.html,boBoxEdit(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 Ribb onPageGroup();
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
https://www.360docs.net/doc/254983463.html,eF10KeyForMenu = false;
//DX按钮
ApplicationIcon属性改变图标
右键Add ApplicationMenu添加evExpress.XtraBars.Ribbon.ApplicationMenu 5.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.BaseTabHitInfohInfo = xtraTabbedMdiM anager.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, Ribbon CustomizationMenuEventArgs 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
https://www.360docs.net/doc/254983463.html,erSkins.OfficeSkins.Register();
https://www.360docs.net/doc/254983463.html,erSkins.BonusSkins.Register();
//设置皮肤
https://www.360docs.net/doc/254983463.html,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, GalleryFilterM enuEventArgs 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, InplaceGa lleryEventArgs 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.barManage r
设置bar的字体与系统字体
barAndDockingController1.AppearancesBar.ItemsFont = new Font(this.Font.F ontFamily, currentFontSize);
9.设置系统字体
DevExpress.Utils.AppearanceObject.DefaultFont = new Font(this.Font.FontFa mily, 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Im ageIndex == 5
{
TreeListNode node = treeList1.FindNodeByID(hi.Node.Id);
treeList1.FocusedNode = node;
this.popupMenu1.ShowPopup(MousePosition);
}
}
}
