DevExpress GridControl 控件点滴

一、常用控件样式

public void setDgv(DevExpress.XtraGrid.Views.Grid.GridView gridView1)
        {
            gridView1.OptionsView.ShowColumnHeaders = true;       //显示列标题
            gridView1.OptionsView.ShowIndicator = false;          // 不显示行标题
            gridView1.OptionsView.ShowGroupPanel = true;          // 显示分组panel
            gridView1.OptionsCustomization.AllowGroup = true;     //是否允许分组
            gridView1.OptionsView.ShowGroupedColumns = true;     //显示分组的列
            gridView1.OptionsView.ShowFilterPanelMode = DevExpress.XtraGrid.Views.Base.ShowFilterPanelMode.Never;   //是否显示过滤面板
            gridView1.OptionsCustomization.AllowFilter = true;                      //是否允许过滤

            gridView1.OptionsCustomization.AllowColumnMoving = true;                //是否允许移动列
            gridView1.OptionsCustomization.AllowColumnResizing = false;              //是否允许调整列宽
            gridView1.OptionsCustomization.AllowSort = true;                          //是否允许排序
            gridView1.OptionsSelection.EnableAppearanceFocusedCell = false;           //是否允许选中单元格
            gridView1.OptionsBehavior.EditorShowMode = DevExpress.Utils.EditorShowMode.Click;
            gridView1.OptionsBehavior.Editable = false;                               //是否允许用户编辑单元格
            gridView1.OptionsView.EnableAppearanceEvenRow = true;                    //是否启用偶数行外观
            gridView1.OptionsView.EnableAppearanceOddRow = true;                     //是否启用奇数行外观
            gridView1.OptionsMenu.EnableColumnMenu = false;                          //禁用列标题右键菜单

            // gridView1.ClearSorting();//禁止排序
            gridView1.PaintStyleName = "Flat";   //设置外观样式
            DevExpress.XtraGrid.Views.Grid.GridViewAppearances Appearance1 = new DevExpress.XtraGrid.Views.Grid.GridViewAppearances(gridView1);

            //列标题颜色：System.Drawing.Color.FromArgb(((int)(((byte)(198)))), ((int)(((byte)(232)))), ((int)(((byte)(243)))));
            //奇数行
            Appearance1.EvenRow.BackColor = System.Drawing.Color.FromArgb(((int)(((byte)()))), ((int)(((byte)()))), ((int)(((byte)()))));
            Appearance1.EvenRow.Font = new System.Drawing.Font("宋体", 9F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)()));
            //偶数行
            Appearance1.OddRow.BackColor = System.Drawing.Color.White;
            Appearance1.OddRow.Font = new System.Drawing.Font("宋体", 9F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)()));
            //选中行
            Appearance1.FocusedRow.BackColor = System.Drawing.Color.FromArgb(((int)(((byte)()))), ((int)(((byte)()))), ((int)(((byte)()))));
            Appearance1.FocusedRow.ForeColor = System.Drawing.Color.Black;
            //分组panel颜色
            Appearance1.GroupPanel.BackColor = System.Drawing.Color.White;
            Appearance1.GroupPanel.BackColor2 = System.Drawing.Color.CornflowerBlue;
            //分组row颜色
            Appearance1.GroupRow.BackColor = System.Drawing.Color.FromArgb(((int)(((byte)()))), ((int)(((byte)()))), ((int)(((byte)()))));
            Appearance1.GroupRow.BackColor2 = System.Drawing.Color.FromArgb(((int)(((byte)()))), ((int)(((byte)()))), ((int)(((byte)()))));
            //空白区域颜色
            Appearance1.Empty.BackColor = System.Drawing.Color.LightYellow;
            //列标题颜色
            Appearance1.HeaderPanel.BackColor = System.Drawing.Color.FromArgb(((int)(((byte)()))), ((int)(((byte)()))), ((int)(((byte)()))));
            //奇数行
            gridView1.Appearance.EvenRow.BackColor = Appearance1.EvenRow.BackColor;
            gridView1.Appearance.EvenRow.Font = Appearance1.EvenRow.Font;
            //偶数行
            gridView1.Appearance.OddRow.BackColor = Appearance1.OddRow.BackColor;
            gridView1.Appearance.OddRow.Font = Appearance1.OddRow.Font;
            //选中行
            gridView1.Appearance.FocusedRow.BackColor = Appearance1.FocusedRow.BackColor;   //选中的行
            gridView1.Appearance.FocusedCell.BackColor = Appearance1.FocusedRow.BackColor;  //选中的单元格
            gridView1.Appearance.FocusedRow.ForeColor = Appearance1.FocusedRow.ForeColor;   //字体颜色
            gridView1.Appearance.GroupPanel.BackColor = Appearance1.GroupPanel.BackColor;
            gridView1.Appearance.GroupPanel.BackColor2 = Appearance1.GroupPanel.BackColor2;
            //分组row颜色
            gridView1.Appearance.GroupRow.BackColor = Appearance1.GroupRow.BackColor;
            //  gridView1.Appearance.GroupRow.BackColor2 = Appearance1.GroupRow.BackColor2;
            //空白区域颜色
            gridView1.Appearance.Empty.BackColor = Appearance1.Empty.BackColor;
            //列标题颜色
            gridView1.Appearance.HeaderPanel.BackColor = Appearance1.HeaderPanel.BackColor;
            //设置分组
            gridView1.GroupSummary.Add(DevExpress.Data.SummaryItemType.Count, "分组1");  //添加分组1，如果不是count，则名称必须与字段名对应
            gridView1.GroupFormat = "{1} {2}";  //默认"{0}: [#image]{1} {2}"; 字段名称：数据 计数=？
            gridView1.Columns["部门名称"].GroupIndex = ;  //设置默认分组列
        }

二、设置分组显示格式

gridView1.GroupFormat = "{0}: [#image]{1} {2}"; //"字段名：图标 字段值";
gridView1.GroupFormat = "{1} {2}";              //"字段值";

三、统计汇总字段

       gridView1.GroupSummary.Add(DevExpress.Data.SummaryItemType.Count, "分组1");  //添加分组1，如果不是count，则名称必须与字段名对应
        gridView1.GroupFormat = "{1} {2}";  //默认"{0}: [#image]{1} {2}"; 字段名称：数据 计数=？
        gridView1.Columns["FieldName1"].GroupIndex = ;  //设置默认分组列

        //分组列格式
        gridView1.GroupSummary.Add(DevExpress.Data.SummaryItemType.Average, "id", gridView1.Columns["id"]);
        gridView1.GroupSummary[].DisplayFormat = "AVG={0:c}";

        gridView1.GroupSummary.Add(DevExpress.Data.SummaryItemType.Count, "姓名", gridView1.Columns["姓名"]);
        ((DevExpress.XtraGrid.GridSummaryItem)gridView1.GroupSummary[gridView1.GroupSummary.Count - ]).DisplayFormat = "小计：{0:N0}";
        //展开
        gridView1.ExpandAllGroups();

四、对列的操作

        //设某一列只读或者不可编辑
         gridView1.Columns[].OptionsColumn.AllowEdit = false;
         gridView1.Columns[].OptionsColumn.ReadOnly = false;   

         //设某一列文字和标题局中显示
         gridView1.Columns[].AppearanceHeader.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;
         gridView1.Columns[].AppearanceCell.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;   

         //去掉某一列上面的自动筛选功能(Filter)
         gridView1.Columns[].OptionsFilter.AllowAutoFilter = false;
         gridView1.Columns[].OptionsFilter.AllowFilter = false;
         gridView1.Columns[].OptionsFilter.ImmediateUpdateAutoFilter = false;   

         //设置冻结列(左冻结)
         gridView1.Columns[].Fixed= DevExpress.XtraGrid.Columns.FixedStyle.Left;   

         //得到单元格数据(0行0列)
         string ss = gridView1.GetRowCellDisplayText(, gridView1.Columns[]);
         string ss = gridView1.GetRowCellValue(, gridView1.Columns[]);
         //设置单元格数据(将0行0列的单元格赋值123)
         gridView1.SetRowCellValue(, gridView1.Columns[], "");   

         //手动添加dev的列
         DevExpress.XtraGrid.Columns.GridColumn Col1 = new DevExpress.XtraGrid.Columns.GridColumn();
         Col1.FieldName="FID";
         Col1.Visible=true;
         Col1.VisibleIndex=gridView1.Columns.Count;
         gridView1.Columns.Add(Col1);

五、一些常用事件

//设置自动增加的行号,需要先添加给gridview添加事件CustomDrawRowIndicator
        private void gridview_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)
        {
            if (e.Info.IsRowIndicator && e.RowHandle >= )
                e.Info.DisplayText = (e.RowHandle + ).ToString();
        }

        //删除: (修改了dgvdel里的datagridviewdel方法)
        public static void datagridviewdel_Dev(DevExpress.XtraGrid.Views.Grid.GridView Mydgv)
        {
            if (MessageBox.Show("你确定要删除选中的记录吗？", "删除提示", MessageBoxButtons.YesNo, MessageBoxIcon.Warning, MessageBoxDefaultButton.Button2, , false) == DialogResult.Yes)
            {
                int iSelectRowCount = Mydgv.SelectedRowsCount;
                if (iSelectRowCount > )
                {
                    Mydgv.DeleteSelectedRows();
                }
            }
        }
        //新增:
        private void btn_add_Click(object sender, EventArgs e)
        {
            gridView1.AddNewRow();
        }
        //新增行初始值设置:
        private void gridView1_InitNewRow(object sender, DevExpress.XtraGrid.Views.Grid.InitNewRowEventArgs e)
        {
            ColumnView View = sender as ColumnView;
            View.SetRowCellValue(e.RowHandle, View.Columns[], gridView1.GetRowCellValue(gridView1.GetRowHandle(gridView1.RowCount - ), gridView1.Columns[])); //复制最后一行的数据到新行
            View.SetRowCellValue(e.RowHandle, View.Columns[], gridView1.GetRowCellValue(gridView1.GetRowHandle(gridView1.RowCount - ), gridView1.Columns[])); //复制最后一行的数据到新行
        }
        //保存 datagridviewsave

六、获取行高

GridViewInfo vi = gridView1.GetViewInfo() as GridViewInfo;
GridRowInfo ri = vi.RowsInfo.FindRow();
int height = ;
if (ri != null)
       height = ri.Bounds.Height;
