C#中gridView常用属性和技巧介绍

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-Place Editor 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=new DevExpress.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(object sender,                            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 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, 0, false) == DialogResult.Yes) 
       { 
           int iSelectRowCount = 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、Advanced BandedView、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gridcontrol view 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 void showData(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(string imagePath) 
        { 
            FileStream files = new FileStream(imagePath, FileMode.Open); 
            byte[] imgByte = new byte [files.Length ]; 
            files.Read(imgByte, 0, imgByte.Length); 
            files.Close(); 
            return imgByte; 
        } 
  
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, ValidateRowEventArgs e) 
  { 
  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.CustomColumnDataEventArgs 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"])); 
             object MinValue = View.GetRowCellValue(e.RowHandle, View.Columns["MinValue"]); 
             object MaxVlaue = 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); 
     return DevExpress.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"])); 
             object MinValue = View.GetRowCellValue(e.RowHandle, View.Columns["MinValue"]); 
             object MaxVlaue = 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 = new RepositoryItemTextEdit(); 
    textEditReg_Id.Mask.EditMask =parentId+"file://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 = new RepositoryItemLookUpEdit(); 
    lookUEParent_Id.Columns.Add(new LookUpColumnInfo("reg_id", 40, "区划编号")); 
    lookUEParent_Id.Columns.Add(new LookUpColumnInfo("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; 
} 
/// <summary> 
/// gridView单元格验证的相关处理程序

    } 
    if (this.gridView1.FocusedColumn.FieldName == "reg_name") 
    {      
     Regex reg=new Regex(@"[\u4e00-\u9fa5]{1,20}"); 
     Match m=reg.Match(e.Value.ToString().Trim()); 
     if (m.Length != e.Value.ToString().Trim().Length) 
     { 
      e.Valid = false; 
      e.ErrorText = "区划名称应为汉字\n长度为1至20"; 
     } 
    } 
}

关于XtraGrid的使用（GridControl小结）来源：51编程网发布时间：2010-04-19Hits：146 
DevExpress XtraGrid的使用（AspxGridControl小结）收藏 
  
自定义焦点行的方法： gridView_bcode.FocusedRowHandle = focuseRowInt; //通过设置GridView 的FocusedRowHandle属性 
   
view plaincopy to clipboardprint? 
//获取焦点行任意单元格的数据     
ColumnView cv = (ColumnView)gridControl_Gongzi.FocusedView;//重新获取此ID 否则无法从表头连删获取不到id    
                        int focusedhandle = cv.FocusedRowHandle;

C#中GridView格式化字符串，其实就是使用DataFromatString的方法，那么现在就向你介绍具体的内容和实现的实例应用，希望对你有所帮助。

在我们从业务逻辑层获得数据实体时候，接下来的事情就是要绑定到控件中。数据实体中的一些字段可以直接绑定到界面中，但是有一些字段需要重新格式化格式。比如货币单位字段，需要显示货币符号和每隔三位显示分隔符;再比如日期字段，数据库中存放的是日期和时间，但是在界面上需要按照XXXX年XX月XX日的格式显示。这时候我们就用到了DataFormatString属性。

﹤asp:GridView ID="grvResult" runat="server"   
AutoGenerateColumns="False" Width="100%"﹥   
﹤Columns﹥   
﹤asp:BoundField HeaderText="预定日期"   
DataField="OperationDate" DataFormatString="{  
0:yyyy-MM-dd}" HtmlEncode="False"﹥   
﹤/asp:BoundField﹥     
﹤asp:BoundField HeaderText="订单总计"   
DataField="TotalRate" DataFormatString="{  
0:C}" HtmlEncode="False"﹥   
﹤/asp:BoundField﹥   
﹤/Columns﹥   
﹤/asp:GridView﹥

例如上面的代码展示了日期和货币两种绑定方式。DataFormatString中的{0}是固定的格式，这和String.Fromat(“{0}”, someString)中的{0}是一个用法，表示绑定上下文的参数索引编号。然后，在后面加入C#格式化字符串，具体的使用方法可以参考MSDN。

C#中GridView格式化字符串注意以下几点

1. 在GridView中的asp:BoundField使用DataFormatString必须设置属性HtmlEncode="False"，否则不起作用。

2. 如果需要使用日期类型的格式化字符串，必须数据实体中对应的字段也应该日起类型的。

3. 格式化字符串C代表货币单位，需要绑定的数据类型应该是数字类型的。如果是字符串类型的不起作用，需要手动添加格式化字符串为DataFormatString="￥{0:C}"。

C#中GridView格式化字符串的基本情况就向你介绍到这里，希望对你学习和理解C#中GridView格式化字符串有所帮助。

   1、在gridview中一直对“删除”不是很理解，在ASP的模式下面，这个删除链接应该有一个行ID标识，以便程序知道删除那一行，或针对这行做一些处理，然而在ASP.net里面也可以用，但是不是最好的。
    2、应该用LinkButton的各种属性，这时候非常方面，而且便于理解。这样不用选中一行（gridview.selectedRow 提供定位信息），然后再点击某种操作了。
    请注意 CommandName, CommandArgument 和 LinkButton的名字 CommandArgument 的对应关系。
    有了 CommandName 就知道是那个LinkButton控件。
    有了 CommandArgument（和行的ID绑定），就知道要处理那一行。
    swicth(CommandName)
    case "sort":{}
    case “delete”：{}
