GirdView1的常用属性

1、C#中gridView常用属性和技巧介绍 - 凌风95时间 2014-08-15 00:37:00  博客园-所有随笔区原文  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.RowsgridView1.FocusedRowHandleFieldName.ToString(); 3.数据只读 gridView1.OptionsBehavior.Editable=false; 4.不显示MasterDetailV

2、iew 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

3、 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 E

4、ditor 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 = DALU

5、se.Query("select fid,fname,fsex from dual").Tables0; Re1.DisplayMember = "FSEX" Re1.ValueMember = "FNAME" 9.设某一列文字和标题局中显示 gridView1.Columns0.AppearanceHeader.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center; gridView1.Columns0.AppearanceCell.TextOptions.HA

6、lignment = DevExpress.Utils.HorzAlignment.Center; 10.去掉某一列上面的自动筛选功能(Filter) gridView1.Columns0.OptionsFilter.AllowAutoFilter = false; gridView1.Columns0.OptionsFilter.AllowFilter = false; gridView1.Columns0.OptionsFilter.ImmediateUpdateAutoFilter = false; 11.设置冻结列(左冻结) gridView1.Columns0.Fixed= DevE

7、xpress.XtraGrid.Columns.FixedStyle.Left; 12.得到单元格数据(0行0列) string ss=gridView1.GetRowCellDisplayText(0, gridView1.Columns0); string ss = gridView1.GetRowCellValue(0, gridView1.Columns0); 13.设置单元格数据(将0行0列的单元格赋值123) gridView1.SetRowCellValue(0, gridView1.Columns0, "123"); 13.手动添加dev的列 DevExpr

8、ess.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_CustomDrawRowIndic

9、ator(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.Gr

10、id.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(); 1

11、6. 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 Column

12、View; View.SetRowCellValue(e.RowHandle, View.Columns0, gridView1.GetRowCellValue(gridView1.GetRowHandle(gridView1.RowCount - 2), gridView1.Columns0); /复制最后一行的数据到新行 View.SetRowCellValue(e.RowHandle, View.Columns1, gridView1.GetRowCellValue(gridView1.GetRowHandle(gridView1.RowCount - 2), gridView1.Col

13、umns1); /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

14、 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.T

15、ype.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" =

16、listi.Name; dr"Department" = listi.Department; string imagePath = "D:C#photos" + listi.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 Fil

17、eStream(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 a

18、s 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 、GridCon

19、trol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".

20、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 = Vie

21、w.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.ToDecim

22、al(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 &

23、 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.GetRowC

24、ellValue(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"

25、;></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.ByteImageCo

26、nverter.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) Grid

27、View 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

28、.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&

29、quot;MaxValue"); if (MinValue != DBNull.Value & MinValue != null & MaxVlaue.ToString() != "" & MaxVlaue != DBNull.Value && MaxVlaue != null & MaxVlaue.ToString() != "") decimal gridColumn2 = Convert.ToDecimal(MinValue); decimal gridColumn1 = Convert.T

30、oDecimal(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

31、 e) GridView view = sender as GridView; DataView dv = view.DataSource as DataView; if (e.IsGetData) string strVal = dve.ListSourceRowIndex"Color".ToString(); if (strVal != "") /e.Value = DevExpress.Utils.StyleLayout.ColorFromString(strVal); e.Value = Common.HexToColor(strVal); el

32、se /Color colorVal = DevExpress.Utils.StyleLayout.ColorFromString(e.Value.ToString(); Color colorVal = (Color)e.Value; dve.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="pare
