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);

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”：{}
