DevExpress GridControl使用方法总结

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);
           }
      }
 }

DEV控件：gridControl常用属性设置 

2011-01-19 09:50

1.隐藏最上面的GroupPanel
   gridView1.OptionsView.ShowGroupPanel=false; 

2.得到当前选定记录某字段的值
  sValue=Table.Rows[gridView1.FocusedRowHandle][FieldName].ToString();

3.数据只读
  gridView1.OptionsBehavior.Editable=false;

4.不显示MasterDetailView
   gridView1.OptionsDetail.EnableMasterViewMode=false;

5.修改最上面的GroupPanel内容
   gridView1.GroupPanelText="柳生飘絮";

6.设置数据源:
    gridControl1.DataSource = dt;
    绑定每一列的FiledName--属性
   对于Oracle数据库,所有的在设计器里写的程序中的字段名必须大写,否则可能绑定不上字段,sqlserver没有这个限制.

7.读写拷贝权限设置
  只读不可拷贝：
    ColumnViewOptionsBehavior.Editable = False

  只读可拷贝:
     ColumnViewOptionsBehavior.Editable = True
     OptionsColumn.AllowEdit = True
     OptionsColumn.ReadOnly = True

  可编辑:
     ColumnViewOptionsBehavior.Editable = True
     OptionsColumn.AllowEdit = True
     OptionsColumn.ReadOnly = False

8.模板列的设置:
   到Columns中，在他的属性中找到ColumnEdit.
   以LookUpEdit为例：
  首先从Designer左边菜单In-PlaceEditor Repository中添加LookUpEdit.取名为Re1.然后.在他的Columns属性中添加3列.Caption依次为:编号,姓名,性别.FieldName依次为:FID,FNAME,FSEX.然后将Re1的NullText设置成空.
　　AutoSearchColumnIndex属性设置为2.ImmediatePopup属性设置为True.
　　SearchMode设置为OnlyInPopup.
　　然后将这个模板列附加到我们上面提到的列1(也就是将列1的ColumnEdit属性设成Re1)
　　最后我们还要在代码里面给Re1绑定数据源和显示项.
          Re1.DataSource =DALUse.Query("select fid,fname,fsex from dual").Tables[0];
          Re1.DisplayMember ="FSEX";
          Re1.ValueMember ="FNAME";

9.设某一列文字和标题局中显示
    gridView1.Columns[0].AppearanceHeader.TextOptions.HAlignment =DevExpress.Utils.HorzAlignment.Center;
    gridView1.Columns[0].AppearanceCell.TextOptions.HAlignment =DevExpress.Utils.HorzAlignment.Center;

 10.去掉某一列上面的自动筛选功能(Filter)
    gridView1.Columns[0].OptionsFilter.AllowAutoFilter = false;
    gridView1.Columns[0].OptionsFilter.AllowFilter =false;
    gridView1.Columns[0].OptionsFilter.ImmediateUpdateAutoFilter =false;

 11.设置冻结列(左冻结)
   gridView1.Columns[0].Fixed= DevExpress.XtraGrid.Columns.FixedStyle.Left;

 12.得到单元格数据(0行0列)
    string ss=gridView1.GetRowCellDisplayText(0,gridView1.Columns[0]);
    string ss = gridView1.GetRowCellValue(0, gridView1.Columns[0]);

 13.设置单元格数据(将0行0列的单元格赋值123)
    gridView1.SetRowCellValue(0, gridView1.Columns[0],"123");

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

 14.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(objectsender,                           DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)
     {
         if (e.Info.IsRowIndicator &&e.RowHandle >= 0)
                e.Info.DisplayText = (e.RowHandle + 1).ToString();
     }

15.删除: (修改了dgvdel里的datagridviewdel方法)
     public static voiddatagridviewdel_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, 0, false) == DialogResult.Yes)
        {
            intiSelectRowCount = Mydgv.SelectedRowsCount;
            if(iSelectRowCount > 0)
            {
             Mydgv.DeleteSelectedRows();
            }
        }
     }

 16. 新增: (对于新增,其本身的AddNewRow方法就可以做到)
     private void btn_add_Click(object sender, EventArgs e)
     {
        gridView1.AddNewRow();
      }
     具体如果对于新加行还有什么特别的设置,可以在它gridView1_InitNewRow事件中填写:
     private void gridView1_InitNewRow(object sender,DevExpress.XtraGrid.Views.Grid.InitNewRowEventArgs e)
     {
        ColumnView View = sender as ColumnView;
        View.SetRowCellValue(e.RowHandle,View.Columns[0],gridView1.GetRowCellValue(gridView1.GetRowHandle(gridView1.RowCount - 2),gridView1.Columns[0])); //复制最后一行的数据到新行

           View.SetRowCellValue(e.RowHandle, View.Columns[1],gridView1.GetRowCellValue(gridView1.GetRowHandle(gridView1.RowCount - 2),gridView1.Columns[1])); //复制最后一行的数据到新行

    }

17. 保存 (第三方控件提供的RefreshData和RefreshDataSource方法对于保存数据都不好使,最后还是使用了Dgvsave的datagridviewsave方法,用这个方法就可以)

18.特效：gridcontrol中有5种view 型式，普通的是gridview，然后分别为cardview、BandedView、AdvancedBandedView、LayoutView；共5种。
  1）、view组中把OptionView下的viewmode 设置成“Carousel”就达到这种“旋转木马”式的gridcontrolview 特效了
  2）、layoutView1.OptionsCarouselMode.PitchAngle 这个属性决定“旋转木马”的pitch angle 螺距角; 螺旋角; 螺旋升角; 俯仰角; 倾角; 节锥半角
  3）、Roll Angle 属性决定着 倾侧角度
  4）、指定数据源，显示数据：
  //显示数据
        private voidshowData(List<Employee > list)
         {
             DataTable dt= new DataTable("OneEmployee");
            dt.Columns.Add("Caption", System.Type.GetType("System.String"));
            dt.Columns.Add("Department",System.Type.GetType("System.String"));
            dt.Columns.Add("PhotoName",System.Type.GetType("System.Byte[]"));

            for(int i = 0; i < list.Count; i++)
             {
                DataRow dr = dt.NewRow();
                dr["Caption"] = list[i].Name;
                dr["Department"] = list[i].Department;
                string imagePath = @"D:\C#\photos\" + list[i].PhotoPath;
                dr["PhotoName"] = getImageByte(imagePath);
                dt.Rows.Add(dr);
             }
            gridControl1.DataSource = dt;
         }

        //返回图片的字节流byte[]
         private byte[] getImageByte(stringimagePath)
         {
             FileStreamfiles = new FileStream(imagePath, FileMode.Open);
             byte[]imgByte = new byte [files.Length ];
            files.Read(imgByte, 0, imgByte.Length);
            files.Close();
             returnimgByte;
        }

19.检查数据的有效性
  在gridview的ValidateRow事件中加入检查代码：
  #region 检查数据
  private void gridView1_ValidateRow(object sender, ValidateRowEventArgse)
   {
   GridView view = sender as GridView;
   view.ClearColumnErrors();

  if (view.GetRowCellValue(e.RowHandle, "ReceiveDate") ==DBNull.Value)
   {
   e.Valid = false;
   view.SetColumnError(view.Columns["ReceiveDate"], "必须指定日期");
   }

  }
   #endregion
   调用gridview.UpdateCurrentRow()方法执行检查

最常用的DevExpress Winform 4个代码片段：

一 、GridControl的删除操作

private void rILinkEditInfoDel_Click(object sender, EventArgs e)
 {
      if (XtraMessageBox.Show("请确定是否删除当前记录？", "警告",MessageBoxButtons.YesNo, MessageBoxIcon.Warning) == DialogResult.Yes)
      {
          DataRow row =gvInfos.GetDataRow(gvInfos.FocusedRowHandle);
          delByCode(row["Code"].ToString());
          XtraMessageBox.Show("操作成功！");
      }
 }

二、绑定非数据表中列

Hashtable ht = new Hashtable();

private void gridView6_CustomUnboundColumnData(object sender, DevExpress.XtraGrid.Views.Base.CustomColumnDataEventArgse)
 {
      GridView View = sender as GridView;
      if (e.RowHandle >= 0)
      {
          object needAlert =View.GetRowCellValue(e.RowHandle, View.Columns["needAlert"]);
          if (needAlert != null &needAlert != DBNull.Value && needAlert.ToString().Trim() !="0" & View.GetRowCellValue(e.RowHandle,View.Columns["Value"]) != DBNull.Value)
          {
             decimal AverValue = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle,View.Columns["Value"]));
              objectMinValue = View.GetRowCellValue(e.RowHandle,View.Columns["MinValue"]);
              objectMaxVlaue = View.GetRowCellValue(e.RowHandle,View.Columns["MaxValue"]);
              if(MinValue != DBNull.Value & MinValue != null & MaxVlaue.ToString() !="" & MaxVlaue != DBNull.Value && MaxVlaue != null &MaxVlaue.ToString() != "")
              {
                 decimal gridColumn2 = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle,View.Columns["MinValue"]));
                 decimal gridColumn1 = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle,View.Columns["MaxValue"]));
                 if (gridColumn2 > AverValue || AverValue > gridColumn1)
                 {
                     if (!ht.ContainsKey("pic"))
                         ht.Add("pic", GetImage(1));
                     e.Value = ht["pic"];
                 }
              }
          }
      }
 }

/// <summary>
 /// 由资源文件获取图片
/// </summary>
 /// <param name="key"></param>
 /// <returns></returns>
 byte[] GetImage(int key)
 {
      Image img =DevExpress.Utils.Controls.ImageHelper.CreateImageFromResources(string.Format("RiverSys.Resources.{0}.gif",key.ToString()), typeof(RiverInfos).Assembly);
      returnDevExpress.XtraEditors.Controls.ByteImageConverter.ToByteArray(img,ImageFormat.Gif);
 }

/// <summary>
 /// 动态根据条件设置行样式
/// </summary>
 /// <param name="sender"></param>
 /// <param name="e"></param>
 private void gridView6_RowStyle(object sender,DevExpress.XtraGrid.Views.Grid.RowStyleEventArgs e)
 {
      GridView View = sender as GridView;
      if (e.RowHandle >= 0)
      {
          object needAlert =View.GetRowCellValue(e.RowHandle, View.Columns["needAlert"]);
          if (needAlert != null &needAlert != DBNull.Value && needAlert.ToString().Trim() !="0" & View.GetRowCellValue(e.RowHandle,View.Columns["Value"]) != DBNull.Value)
          {
             decimal AverValue = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle, View.Columns["Value"]));
              objectMinValue = View.GetRowCellValue(e.RowHandle,View.Columns["MinValue"]);
              objectMaxVlaue = View.GetRowCellValue(e.RowHandle,View.Columns["MaxValue"]);
              if(MinValue != DBNull.Value & MinValue != null & MaxVlaue.ToString() !="" & MaxVlaue != DBNull.Value && MaxVlaue != null &MaxVlaue.ToString() != "")
              {
                 decimal gridColumn2 = Convert.ToDecimal(MinValue);
                 decimal gridColumn1 = Convert.ToDecimal(MaxVlaue);
                 if (gridColumn2 > AverValue || AverValue > gridColumn1)
                 {
                     e.Appearance.ForeColor = Color.Red;
                     e.Appearance.BackColor = Color.LightGray;
                 }
              }
          }
      }
 }

三、GridControl 中颜色选择控件

private void gvMapColor_CustomUnboundColumnData(object sender,DevExpress.XtraGrid.Views.Base.CustomColumnDataEventArgs e)
 {
      GridView view = sender as GridView;
      DataView dv = view.DataSource as DataView;
      if (e.IsGetData)
      {
          string strVal =dv[e.ListSourceRowIndex]["Color"].ToString();
          if (strVal != "")
          {
             //e.Value = DevExpress.Utils.StyleLayout.ColorFromString(strVal);
             e.Value = Common.HexToColor(strVal);
          }
      }
      else
      {
          //Color colorVal =DevExpress.Utils.StyleLayout.ColorFromString(e.Value.ToString());
          Color colorVal =(Color)e.Value;
         dv[e.ListSourceRowIndex]["Color"] =Common.RGB_HEX(colorVal.ToArgb());
      }
 }

四、关于 GridControl 验证示例

/**//// <summary>
 /// 初始化GridView，绑定数据
/// </summary>
 /// <param name="parentId"></param>
 private void GridViewBindData(string parentId)
 {
 this.gridView1.Columns.Clear();
 this.FDs= areaSetupActionHelper.getDsRegionByParentId(parentId);
 this.gridCArea.DataSource =this.FDs.Tables[0].DefaultView;

    this.gridView1.Columns["id"].VisibleIndex =-1;
     this.gridView1.Columns["childCounts"].VisibleIndex= -1;

    this.gridView1.Columns["reg_id"].Caption ="区划编号";
     this.gridView1.Columns["reg_name"].Caption ="区划名称";
     this.gridView1.Columns["parent_id"].Caption ="父区划编号";
     this.gridView1.Columns["reg_desc"].Caption ="区划描述";
     this.gridView1.Columns["parent_id"].ImageIndex =1;
     this.gridView1.Columns["reg_desc"].ImageIndex = 0;

    RepositoryItemTextEdit textEditReg_Id = newRepositoryItemTextEdit();
     textEditReg_Id.Mask.EditMask =parentId+"\\d{2,3}";
     textEditReg_Id.Mask.MaskType =DevExpress.XtraEditors.Mask.MaskType.Regular;

    this.gridView1.Columns["reg_id"].ColumnEdit =textEditReg_Id;

    this.gridView1.Columns["reg_desc"].ColumnEdit= new RepositoryItemMemoExEdit();

    TreeListNode node =this.treelArea.FocusedNode.ParentNode;
     string fid =node==null?"0":node.GetValue("RegID").ToString().Trim();
     DataSet ds =areaSetupActionHelper.getDsRegionByParentId(fid);
     RepositoryItemLookUpEdit lookUEParent_Id = newRepositoryItemLookUpEdit();
     lookUEParent_Id.Columns.Add(newLookUpColumnInfo("reg_id", 40, "区划编号"));
     lookUEParent_Id.Columns.Add(newLookUpColumnInfo("reg_name", 40, "区划名称"));
     lookUEParent_Id.DataSource = ds.Tables[0].DefaultView;
     lookUEParent_Id.ValueMember = "reg_id";
     lookUEParent_Id.DisplayMember = "reg_id";
     this.gridView1.Columns["parent_id"].ColumnEdit =lookUEParent_Id;
 }
