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 ///<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> 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();

}///查看选择中的记录 CellMerging(单元格合并的效果) /// CellMerging(单元格合并的效果) gridView1.OptionsView.AllowCellMerge = ceMerging.Checked; Fixed Bands(bandedGridView) ///两边固定 gridBand3 的一列的 Fixed 属性改成 Right,Left,None ///固定与非固定列之间的距离用 bandedGridView2.FixedLineWidth = (int)numFixedLineWidth.Value; ///设置列的颜色  打开 Run Designer 选中 Columns 选中要改变的列 里面有 AppearanceCell （设置列的外观）和 AppearanceHeader（设置表格头的外观）  或者选中该列查看“属性”里面也有这两个属性。 ///统计 （gridView bandedGridView 通用） 分组统计和全部统计： 全部统计：在最下面显示统计的结果。 Run Designer->Total Summary //->General 设置显示 //->Columns 对特定列来设置统计 汇总结果是否显示：可以通过 gridControl 的 view的 ShowFooter属性来设置表格下面的汇总结果 分组统计： 以上就是“分组”的 显示在每个分组下面来显示汇总结果。 通过 bandedGridView2.GroupFooterShowMode= GroupFooterShowMode.。。。。设置分组的显示模式。 ///GridView 设置菜单 #region Grid events private void gridView1_ShowGridMenu(object sender, DevExpress.XtraGrid.Views.Grid.GridMenuEventArgs e) { if(e.MenuType == DevExpress.XtraGrid.Views.Grid.GridMenuType.Column) { DevExpress.XtraGrid.Menu.GridViewColumnMenu menu = e.Menu as DevExpress.XtraGrid.Menu.GridViewColumnMenu;
