Dev属性设置

DisplayFormat 设置显示格式如：{0:P}表示显示为百分号模式。如数据源中为0.5。表示出来为50%

2、GridContro总合计及分组合计：

常规总合计直接RunDesigner-Group Summary Items

DisplayFormat 设置显示格式如：{0:P}表示显示为百分号模式。如数据源中为0.5。表示出来为50%

FieldName 设置显示的对应列

ShowInGroupColumnFooter 在那一列下面显示

SummaryType 合计方式。选择Custom表示自定义。CustomSummaryCalculate事件可处理

//Footer行自定义列合计
  GridView view = sender as GridView;
  if (e.Item == view.Columns["RateZk"].SummaryItem)
  {
    decimal x = Convert.ToDecimal(view.Columns["RetailFAmount"].SummaryItem.SummaryValue);
    decimal y = Convert.ToDecimal(view.Columns["RetailAmount"].SummaryItem.SummaryValue);
    view.Columns["RateZk"].SummaryItem.DisplayFormat = "{0:P}";
    )
    e.TotalValue = x / y;
    else
    e.TotalValue = ;
  }

GridContro导出Excel操作：

SaveFileDialog saveFileDialog = new SaveFileDialog();
   saveFileDialog.Title = "导出Excel";
   saveFileDialog.Filter = "Excel文件(*.xls)|*.xls";
   DialogResult dialogResult = saveFileDialog.ShowDialog(this);
   if (dialogResult == DialogResult.OK)
   {
     this.gvbrowse.OptionsPrint.AutoWidth = false; //设置导出的Excel自动调整列宽，列宽和控件的列宽一致
     this.gcbrowse.ExportToXls(saveFileDialog.FileName);
     //this.gcbrowse.ExportToXlsOld(saveFileDialog.FileName);//这个方法默认会自动调整列宽，但是office10以上版本有的会报错
     DevExpress.XtraEditors.XtraMessageBox.Show("保存成功！", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
     this.gvbrowse.OptionsPrint.AutoWidth = true;
   }

GridControl列要显示百分号：

Run Designer-Columns列 FormatType="Numeric" FormatString="p"

自动调整所有字段宽度  this.gridView1.BestFitColumns();

显示滚动条：gridView1.OptionsView.ColumnAutoWidth属性是true，即各列的宽度自动调整，你把它设成false，就会出现了。

设置奇、偶行交替颜色

  • OptionsView.EnableAppearanceEvenRow = true；OptionsView.EnableAppearanceOddRow = true;

MultiSelect = true;   //设置可多选

 MultiSelectMode =CellSelect/RowSelect;//多选行还是多选单元格（一般选RowSelect）

//禁用标题行过滤

AllowFilter = false; 

//禁用标题行排序

AllowSort = false;

//禁止列移动

AllowColumnMoving = false;

//禁止改变列宽

AllowColumnResizing = false;

FocusRectStyle = None; //取消点击后的虚线框

 下拉框清空

1、清值 comboboxedit2.editvalue=null;

2、清列表 comboboxedit2.properties.items.clear();

GridView 设置选中行的颜色

  GridView : Run Designer ->  Appearences : selectRow & FocusedRow (两项都要设置)  

  BackColor :  MediumSlateBlue  背景色

　ForeColor :  White    前景色 字体颜色

GridView 设置标题行以及内容行 数据居中

 标题行 10 所述 在HeadPanel 里有一个TextOptions  展开之后 将HAlignment :  Center  

 如果是将内容行数据居中.有两种方法 1 : 逐行设置  2 : 设置Appearences

 1 : GridView -> Run Designer -> Columns  -> AppearanceCell ->  TextOptions 找到HAlignment :  Center .

 2 : GridView -> Run Designer -> Appearance ->  ViewCaption -> TextOptions -> HAlignment : Center

GridView 添加 序号 列

  GridView : Run Designer ->  Event  -> CustomDrawRowIndicator

 在事件中添加代码

public static void DrawRowIndicator(this GridView gridView, int width = 40, string headTitle = "行号")
        {

            gridView.CustomDrawRowIndicator += (sender, e) =>
            {
                e.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;
                if (e.Info.Kind == DevExpress.Utils.Drawing.IndicatorKind.Header)
                {
                    e.Appearance.DrawBackground(e.Cache, e.Bounds);
                    e.Appearance.DrawString(e.Cache, headTitle, e.Bounds);
                    e.Handled = true;
                }
                if (e.Info.IsRowIndicator)
                {

                    if (e.RowHandle >= 0)
                    {
                        e.Info.DisplayText = (e.RowHandle + 1).ToString();
                    }
                    else if (e.RowHandle < 0 && e.RowHandle > -1000)
                    {
                        e.Info.Appearance.BackColor = System.Drawing.Color.AntiqueWhite;
                        e.Info.DisplayText = "G" + e.RowHandle.ToString();
                    }
                }
            };
            gridView.IndicatorWidth = width != 0 ? width : 40;
        }

另外在 Run Desginer ->  IndicatorWidth  设置序号列的宽度 一般50左右就比较适合一些了.

            }
            return base.GetLocalizedString(id);
        }
    }

皮肤设置：

  DevExpress.UserSkins.OfficeSkins.Register(); //注册office的皮肤 请先加入引用office的dll文件，关于如何引用 请看下文
            DevExpress.UserSkins.BonusSkins.Register(); //注册BonusSkins的皮肤
           if (!DevExpress.Skins.SkinManager.AllowFormSkins)
               DevExpress.Skins.SkinManager.EnableFormSkins();
            DevExpress.LookAndFeel.UserLookAndFeel.Default.SkinName = "Black"; //默认黑背景

 DevExpress实现GridView当无数据行时提示消息  https://ctolib.com/topics-51130.html

/// <summary>

DevExpress实现GridControl列头绘制Checkbox的方法  https://ctolib.com/topics-51144.html    http://aloysians.com/blog/getInfo/52837/1491226375

public static void DrawHeaderCheckBox(this GridView view, RepositoryItemCheckEdit checkItem, string fieldName, ColumnHeaderCustomDrawEventArgs e)
{
  /*说明：

   * }
   */
  if (e.Column != null && e.Column.FieldName.Equals(fieldName))
  {
 e.Info.InnerElements.Clear();
 e.Painter.DrawObject(e.Info);
 DrawCheckBox(checkItem, e.Graphics, e.Bounds, getCheckedCount(view, fieldName) == view.DataRowCount);
 e.Handled = true;
  }
}
private static void DrawCheckBox(RepositoryItemCheckEdit checkItem, Graphics g, Rectangle r, bool Checked)
{
  CheckEditViewInfo _info;
  CheckEditPainter _painter;
  ControlGraphicsInfoArgs _args;
  _info = checkItem.CreateViewInfo() as CheckEditViewInfo;
  _painter = checkItem.CreatePainter() as CheckEditPainter;
  _info.EditValue = Checked;

  _info.Bounds = r;

                e.Painter.DrawObject(e.Info);
                DevControlHelper.DrawCheckBox(e, _mCheckStatus);
                e.Handled = true;
            }
        }

        public static void DrawCheckBox(ColumnHeaderCustomDrawEventArgs e, bool chk)
        {

            if (repositoryCheck == null) return;
            var g = e.Graphics;
            var r = e.Bounds;

            var info = repositoryCheck.CreateViewInfo() as CheckEditViewInfo;

            if (info == null) return;
            info.EditValue = chk;
            info.Bounds = r;
            info.CalcViewInfo(g);

 DevExpress中GridControl中实现checkbox多行选中

在我们要绑定的容器中添加一个新列

我用的是DataTable 在DataTable中添加一个新列代码如下

            //新建一个数据表 probll.GetProductAll自己写的方法
            DataTable db = probll.GetProductAll(4, pageIndex, "申请中", 0, out pageCount);
            //在表中增加一个列 add（列名，列类型）
            db.Columns.Add("check", typeof(bool));
            //给每一行的该列赋值
            for (int i = 0; i < db.Rows.Count; i++)
            {
                db.Rows[i]["check"] = "false";
            }

注意：新增列的类型为bool类型

设置可以多选

gridView1 .OptionsSelection.MultiSelect = true; 
gridView1 .OptionsSelection.MultiSelectMode = DevExpress.XtraGrid.Views.Grid.GridMultiSelectMode.RowSelect;

设置获取选中行的需要值

string value="";  
          string strSelected="";  
            for (int i = 0; i < gridView1.RowCount; i++)  
           {   //   获取选中行的check的值       
               value = gridView1.GetDataRow(i)["check"].ToString();  
               if (value == "True")  
               {
                 // productid 是我绑定数据表的字段 可以自己根据需求定义 这样就可以实现文中开始处的功能了                
                 strSelected += gridView1.GetRowCellValue(i, "productid");
                }             
           }

gridControl：给该列添加组件(如按钮)  三种方法
法一：打开设计器(Run Designer)，选择左侧Repository，点击In-place Editor Repository（内嵌编辑器）,点击Add右侧的下拉菜单


，选择你想添加的控件，比如ComboBoxEdit，再在右侧编辑控件的属性，ComboBox的话就可以设置Data下的Items集合，然后点左侧


Main里的Columns，点你想在上头添加控件的列，找右侧Data下的ColumnEdit，点最右边的下拉菜单，点Existing左侧的加号，就能找


到你刚才的控件，添加。会默认给该列的每一个格都加上这个控件。


法二：点击你想添加控件的列标题，再点属性栏中的ColumnEdit，下拉菜单点new，选择想添加的控件，然后Column Edit左侧会出现加


号，展开加号，下方会出现许多子属性，这些都是设置内嵌的控件的属性的。
法三：直接写代码。
②       拖动一个gridControl控件，改变视图为BandedGridview，属性栏中点OptionView，选择NewItemRowPosition，选Bottom
②添加引用：usingDevExpress.XtraGrid.Views.BandedGrid;
form的构造函数中添加代码：


BandedGridColumn newColumn = bandedGridView1.Columns.Add() as BandedGridColumn;
           newColumn.Caption = "Country";
           bandedGridView1.Bands[0].Columns.Add(newColumn);
            newColumn.Visible = true;
②（假设添加的控件是计算器）添加引用：usingDevExpress.XtraEditors.Repository;
form的构造函数中继续添加代码，效果图
RepositoryItemCalcEdit calcEdit = new RepositoryItemCalcEdit();
           gridControl.RepositoryItems.Add(calcEdit);
            newColumn.ColumnEdit = calcEdit;
