DevExpress控件使用使用技巧小结

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)

{
