第三方控件使用大全

第三方控件使用大全一、ComboBoxEdit 1、如何使其不可编辑 TextEditStyle 设置为：DisableTextEditor 2、如何设置鼠标为手形 Cursor 设置为：Hand 二、GridControl 1、如何解决单击记录整行选中的问题 View->OptionsBehavior->EditorShowMode 设置为：Click 2、如何新增一条记录 (1)、gridView.AddNewRow() (2)、实现gridView_InitNewRow事件 3、如何解决GridControl记录能获取而没有显示出来的问题 gridView.populateColumns(); 4、如何让行只能选择而不能编辑（或编辑某一单元格） (1)、View->OptionsBehavior->EditorShowMode 设置为：Click (2)、View->OptionsBehavior->Editable 设置为：false 5、如何禁用GridControl中单击列弹出右键菜单设置Run Design->OptionsMenu->EnableColumnMenu 设置为：false 6、如何隐藏GridControl的GroupPanel表头设置Run Design->OptionsView->ShowGroupPanel 设置为：false 7、如何禁用GridControl中列头的过滤器过滤器如下图所示：设置 Run Design->OptionsCustomization->AllowFilter 设置为：false 8、如何在查询得到0条记录时显示自定义的字符提示/显示如图所示：方法如下： //When no Records Are Being Displayed private void gridView1_CustomDrawEmptyForeground(object sender, CustomDrawEventArgs e) { //方法一（此方法为GridView设置了数据源绑定时，可用） ColumnView columnView = sender as ColumnView; BindingSource bindingSource = this.gridView1.DataSource as BindingSource; if(bindingSource.Count == 0) { string str = "没有查询到你所想要的数据!"; Font f = new Font("宋体", 10, FontStyle.Bold); Rectangle r = new Rectangle(e.Bounds.Top + 5, e.Bounds.Left + 5, e.Bounds.Right - 5, e.Bounds.Height - 5); e.Graphics.DrawString(str, f, Brushes.Black, r); } //方法二（此方法为GridView没有设置数据源绑定时，使用，一般使用此种方法） if (this._flag) { if (this.gridView1.RowCount == 0) { string str = "没有查询到你所想要的数据!"; Font f = new Font("宋体", 10, FontStyle.Bold); Rectangle r = new Rectangle(e.Bounds.Left + 5, e.Bounds.Top + 5, e.Bounds.Width - 5, e.Bounds.Height - 5); e.Graphics.DrawString(str, f, Brushes.Black, r); } } } 9、如何显示水平滚动条？设置this.gridView.OptionsView.ColumnAutoWidth = false; 10、如何定位到第一条数据/记录？设置 this.gridView.MoveFirst() 11、如何定位到下一条数据/记录？

设置 this.gridView.MoveNext() 12、如何定位到最后一条数据/记录？设置 this.gridView.MoveLast() 13、设置成一次选择一行，并且不能被编辑 this.gridView1.FocusRectStyle = DevExpress.XtraGrid.Views.Grid.DrawFocusRectStyle.RowFocus; this.gridView1.OptionsBehavior.Editable = false; this.gridView1.OptionsSelection.EnableAppearanceFocusedCell = false; 14、如何显示行号？ this.gridView1.IndicatorWidth = 40; //显示行的序号 private void gridView1_CustomDrawRowIndicator(object sender, RowIndicatorCustomDrawEventArgs e) { if (e.Info.IsRowIndicator && e.RowHandle>=0) { e.Info.DisplayText = (e.RowHandle + 1).ToString(); } } 15、如何让各列头禁止移动？设置gridView1.OptionsCustomization.AllowColumnMoving = false; 16、如何让各列头禁止排序？设置gridView1.OptionsCustomization.AllowSort = false; 17、如何禁止各列头改变列宽？设置gridView1.OptionsCustomization.AllowColumnResizing = false;

三、navBarControl 1、如何在每一个navBarGroup里添加自己想要的控件设置GroupStyle: ControlContainer 2、如何设置navBarGroup有滚动条设置SkinExplorerBarViewScrollStyle:ScrollBar 3、如休把navBarGroup设置成如下样式如图所示：设置navBarGroup的PaintStyleName属性为: SkinNavigationPane 四、toolTipController 效果图如下： 1、如何设置显示的时间长短

设置this.toolTipController1.AutoPopDelay = 2000; 2、如何在屏幕上显示如上图所示的效果 ToolTipControllerShowEventArgs args = this.toolTipController1.CreateShowArgs(); this.toolTipController1.SetToolTip(this.sbtnYes, "请选择一条记录!"); this.toolTipController1.SetTitle(this.sbtnYes, "提示"); this.toolTipController1.SetToolTipIconType(this.sbtnYes, DevExpress.Utils.ToolTipIconType.Exclamation); this.toolTipController1.ShowBeak = true; this.toolTipController1.ShowShadow = true; this.toolTipController1.Rounded = true; this.toolTipController1.ShowHint("请选择一条记录!", "提示"); args.ToolTip = "请选择一条记录!"; args.Title = "提示"; 3、如何设置边框的颜色 this.toolTipController1.Appearance.BorderColor = Color.Red; 五、TextEdit 1、如何设置TextEdit为多行，可拉伸设置TextEdit的Propertity->AutoHeight为：False 六、LayoutControl 1、如何设置LayoutItem为隐藏设置LayoutItem.Visibility = Never 七、TreeList 1、如何隐藏TreeList的列头设置TreeListr的OptionsView的ShowColumns属性为：False 2、如何八、PictureEdit 1、如何禁止PictureEdit的右键菜单？设置PictureEdit的Properties->ShowMenu为：false 九、TreeList 1、如何让TreeList的每个结点高亮显示？效果如下：

代码如下： private void treeList1_CustomDrawNodeCell(object sender, DevExpress.XtraTreeList.CustomDrawNodeCellEventArgs e) { TreeList node = sender as TreeList; if (e.Node == node.FocusedNode) { e.Graphics.FillRectangle(SystemBrushes.Window, e.Bounds); Rectangle r = new Rectangle(e.EditViewInfo.ContentRect.Left, e.EditViewInfo.ContentRect.Top, Convert.ToInt32(e.Graphics.MeasureString(e.CellText, treeList1.Font).Width + 1), Convert.ToInt32(e.Graphics.MeasureString(e.CellText,treeList1.Font).Height)); e.Graphics.FillRectangle(SystemBrushes.Highlight, r); e.Graphics.DrawString(e.CellText, treeList1.Font, SystemBrushes.HighlightText, r); e.Handled = true; } } //============================================================================ //===============================以下内容为收集=============================== //============================================================================ 一、改变grid的样式。 DevExpress.XtraGrid.Design.XAppearances xapp; xapp=new DevExpress.XtraGrid.Design.XAppearances(System.Environment.GetFolderPath(System.Environment.SpecialFolder.System) + "\\DevExpress.XtraGrid.Appearances.xml "); xapp.LoadScheme(“样式名字”, gridControl1.MainView); 二、选择单元设置和取所选的值 gridView1.OptionsSelection.MultiSelect = ceMultiSelect.Checked; //多行选择 gridView1.OptionsSelection.MultiSelectMode= GridMultiSelectMode.CellSelect; gridView1.OptionsSelection.MultiSelectMode= GridMultiSelectMode. RowSelect; // 三、gridview的控制

gridView1.OptionsView.NewItemRowPosition = NewItemRowPosition.Bottom//Top/None; ///<设置gridView的按钮> gridView1.ShowButtonMode = ShowButtonModeEnum.。。。。。。 gridView1.OptionsBehavior.Editable = chEdit.Checked; //设置按钮是否可用 ///向选中的空间输入字符串 SendKeys.Send(“fsfds”); ///控件焦点 gridControl1.Focus(); 四、cardView的设置 ///是否现实快捷按钮CustomizeButton cardView1.OptionsView.ShowQuickCustomizeButton=true/false; ///设置CustomizeButton的能否排序和过滤 foreach(GridColumn col in cardView1.Columns) { col.OptionsColumn.AllowSort} foreach(GridColumn col in cardView1.Columns) { col.OptionsFilter.AllowFilter} ///card的头上的ico显示 cardView1.LayoutChanged(); ///card的头上的标题改变显示 cardView1.CardCaptionFormat =””; ///cardview显示的单个记录的折叠按钮 cardView1.OptionsView.ShowCardExpandButton=true; /// cardView1.MaximumCardColumns =iSize cardView1.MaximumCardRows = val; cardView1.OptionsBehavior.AutoHorzWidth ///多选 cardView1.OptionsSelection.MultiSelect = ceMultiSelect.Checked; foreach(int i in cardView1.GetSelectedRows()) { DataRow row = cardView1.GetDataRow(i); if(ret != "") ret += "\r\n"; ret += string.Format("{0} / {1} : {2:$#,0.00}", row["Trademark"], row["Model"], row["Price"]); }///查看选择中的记录 CellMerging(单元格合并的效果)

///<取当前选中的值> string GetSelectedRows(GridView view) { string ret = ""; int rowIndex = -1; if(view.OptionsSelection.MultiSelectMode == GridMultiSelectMode.RowSelect) { foreach(int i in gridView1.GetSelectedRows()) { DataRow row = gridView1.GetDataRow(i); if(ret != "") ret += "\r\n"; ret += string.Format("Company Name: {0} (#{1})", row["CompanyName"], i); } } else { foreach(GridCell cell in view.GetSelectedCells()) { if(rowIndex != cell.RowHandle) { if(ret != "") ret += "\r\n"; ret += string.Format("Row: #{0}", cell.RowHandle); } ret += "\r\n " + view.GetRowCellDisplayText(cell.RowHandle, cell.Column); rowIndex = cell.RowHandle; } } return ret; } ///<设置选中的颜色>//半透明的效果 private void icbTranslucentColors_CheckedChanged(object sender, System.EventArgs e) { if(icbTranslucentColors.Checked) { gridView1.Appearance.SelectedRow.BackColor = Color.FromArgb(30, 0, 0, 240); gridView1.Appearance.FocusedRow.BackColor = Color.FromArgb(60, 0, 0, 240); } else { gridView1.Appearance.SelectedRow.Reset(); gridView1.Appearance.FocusedRow.Reset(); } } ///<自动添加一行>
