//============================================================================

//===============================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();

///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)

///

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

l   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）

l   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;

                   menu.Items.Clear();

                   if(menu.Column != null) {

                       menu.Items.Add(CreateCheckItem("Not Fixed", menu.Column, FixedStyle.None, imageList2.Images[0]));

                       menu.Items.Add(CreateCheckItem("Fixed Left", menu.Column, FixedStyle.Left, imageList2.Images[1]));

                       menu.Items.Add(CreateCheckItem("Fixed Right", menu.Column, FixedStyle.Right, imageList2.Images[2]));

                   }

              }

         }

         #endregion

         #region New column menu

         DXMenuCheckItem CreateCheckItem(string caption, GridColumn column, FixedStyle style, Image image) {

              DXMenuCheckItem item = new DXMenuCheckItem(caption, column.Fixed == style, image, new EventHandler(OnFixedClick));

              item.Tag = new MenuInfo(column, style);

              return item;

         }

         void OnFixedClick(object sender, EventArgs e) {

              DXMenuItem item = sender as DXMenuItem;

              MenuInfo info = item.Tag as MenuInfo;

              if(info == null) return;

              info.Column.Fixed = info.Style;

         }

         class MenuInfo {

              public MenuInfo(GridColumn column, FixedStyle style) {

                   this.Column = column;

                   this.Style = style;

              }

              public FixedStyle Style;

              public GridColumn Column;

         }

#endregion

///gridview cardView自动行高

l   行高自动匹配

  gridView1.OptionsView.RowAutoHeight = ce.Checked;

  cardView1.OptionsBehavior.FieldAutoHeight = ce.Checked;

l   当文字多的时候（行高自动匹配 设置是才有用）

     repositoryItemMemoEdit1.LinesCount = ce.Checked ? 0 : 1;

     设置自动全部显示该的所有行。

     repositoryItemPictureEdit1.CustomHeight = ce.Checked ? 0 : 40;

                       case 0:

                            break;

         }

         void SetSortMode(GridColumn column, ColumnSortMode sortMode) {

              column.SortMode = sortMode;

              column.GroupIndex = 0;

         }

改变分组样式

gridView1.OptionsView.GroupDrawMode = (GroupDrawMode)

///清除分组

gridView1.ClearGrouping();

foreach(GridColumn column in gridView1.Columns) {

                       column.GroupInterval = ColumnGroupInterval.Default;
