DevExpress是非常主流的.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.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.BaseTabHitInfo hInfo = 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);
}
}
}
