DV之GridControl常用屬設置.doc

成都軟件開發(fā)成都網(wǎng)站建設 成都凡迪軟件 DEV控件：gridControl常用屬性設置2011-01-19 09:501.隱藏最上面的GroupPanel gridView1.OptionsView.ShowGroupPanel=false; 2.得到當前選定記錄某字段的值 sValue=Table.RowsgridView1.FocusedRowHandleFieldName.ToString();3.數(shù)據(jù)只讀 gridView1.OptionsBehavior.Editable=false;4.不顯示MasterDetailView gridView1.OptionsDetail.EnableMasterViewMode=false;5.修改最上面的GroupPanel內容 gridView1.GroupPanelText=柳生飄絮;6.設置數(shù)據(jù)源: gridControl1.DataSource = dt; 綁定每一列的FiledName-屬性 對于Oracle數(shù)據(jù)庫,所有的在設計器里寫的程序中的字段名必須大寫,否則可能綁定不上字段,sqlserver沒有這個限制.7.讀寫拷貝權限設置 只讀不可拷貝： ColumnViewOptionsBehavior.Editable = False 只讀可拷貝: ColumnViewOptionsBehavior.Editable = True OptionsColumn.AllowEdit = True OptionsColumn.ReadOnly = True 可編輯: ColumnViewOptionsBehavior.Editable = True OptionsColumn.AllowEdit = True OptionsColumn.ReadOnly = False8.模板列的設置: 到Columns中，在他的屬性中找到ColumnEdit. 以LookUpEdit為例： 首先從Designer左邊菜單In-Place Editor Repository中添加LookUpEdit.取名為Re1.然后.在他的Columns屬性中添加3列.Caption依次為:編號,姓名,性別.FieldName依次為:FID,FNAME,FSEX.然后將Re1的NullText設置成空.AutoSearchColumnIndex屬性設置為2.ImmediatePopup屬性設置為True.SearchMode設置為OnlyInPopup.然后將這個模板列附加到我們上面提到的列1(也就是將列1的ColumnEdit屬性設成Re1)最后我們還要在代碼里面給Re1綁定數(shù)據(jù)源和顯示項. Re1.DataSource = DALUse.Query(select fid,fname,fsex from dual).Tables0; Re1.DisplayMember = FSEX; Re1.ValueMember = FNAME;9.設某一列文字和標題局中顯示 gridView1.Columns0.AppearanceHeader.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center; gridView1.Columns0.AppearanceCell.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;10.去掉某一列上面的自動篩選功能(Filter) gridView1.Columns0.OptionsFilter.AllowAutoFilter = false; gridView1.Columns0.OptionsFilter.AllowFilter = false; gridView1.Columns0.OptionsFilter.ImmediateUpdateAutoFilter = false;11.設置凍結列(左凍結) gridView1.Columns0.Fixed= DevExpress.XtraGrid.Columns.FixedStyle.Left;12.得到單元格數(shù)據(jù)(0行0列) string ss=gridView1.GetRowCellDisplayText(0, gridView1.Columns0); string ss = gridView1.GetRowCellValue(0, gridView1.Columns0);13.設置單元格數(shù)據(jù)(將0行0列的單元格賦值123) gridView1.SetRowCellValue(0, gridView1.Columns0, 123);13.手動添加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.設置自動增加的行號,需要先添加給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.刪除: (修改了dgvdel里的datagridviewdel方法) public static void datagridviewdel_Dev(DevExpress.XtraGrid.Views.Grid.GridView Mydgv) if (MessageBox.Show(你確定要刪除選中的記錄嗎？, 刪除提示, MessageBoxButtons.YesNo, MessageBoxIcon.Warning, MessageBoxDefaultButton.Button2, 0, false) = DialogResult.Yes) int iSelectRowCount = Mydgv.SelectedRowsCount; if (iSelectRowCount 0) Mydgv.DeleteSelectedRows(); 16. 新增: (對于新增,其本身的AddNewRow方法就可以做到) private void btn_add_Click(object sender, EventArgs e) gridView1.AddNewRow(); 具體如果對于新加行還有什么特別的設置,可以在它gridView1_InitNewRow事件中填寫: private void gridView1_InitNewRow(object sender, DevExpress.XtraGrid.Views.Grid.InitNewRowEventArgs e) ColumnView View = sender as ColumnView; View.SetRowCellValue(e.RowHandle, View.Columns0, gridView1.GetRowCellValue(gridView1.GetRowHandle(gridView1.RowCount - 2), gridView1.Columns0); /復制最后一行的數(shù)據(jù)到新行 View.SetRowCellValue(e.RowHandle, View.Columns1, gridView1.GetRowCellValue(gridView1.GetRowHandle(gridView1.RowCount - 2), gridView1.Columns1); /復制最后一行的數(shù)據(jù)到新行 17. 保存 (第三方控件提供的RefreshData和RefreshDataSource方法對于保存數(shù)據(jù)都不好使,最后還是使用了Dgvsave的datagridviewsave方法,用這個方法就可以)18.特效：gridcontrol中有5種view 型式，普通的是gridview，然后分別為cardview、BandedView、Advanced BandedView、LayoutView；共5種。 1）、view組中把OptionView下的viewmode 設置成“Carousel”就達到這種“旋轉木馬”式的gridcontrol view 特效了 2）、layoutView1.OptionsCarouselMode.PitchAngle 這個屬性決定“旋轉木馬”的pitch angle 螺距角; 螺旋角; 螺旋升角; 俯仰角; 傾角; 節(jié)錐半角 3）、Roll Angle 屬性決定著 傾側角度 4）、指定數(shù)據(jù)源，顯示數(shù)據(jù)： /顯示數(shù)據(jù) private void showData(List 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 = 0) object needAlert = View.GetRowCellValue(e.RowHandle, View.ColumnsneedAlert); if (needAlert != null & needAlert != DBNull.Value & needAlert.ToString().Trim() != 0 & View.GetRowCellValue(e.RowHandle, View.ColumnsValue) != DBNull.Value) decimal AverValue = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle, View.ColumnsValue); object MinValue = View.GetRowCellValue(e.RowHandle, View.ColumnsMinValue); object MaxVlaue = View.GetRowCellValue(e.RowHandle, View.ColumnsMaxValue); if (MinValue != DBNull.Value & MinValue != null & MaxVlaue.ToString() != & MaxVlaue != DBNull.Value & MaxVlaue != null & MaxVlaue.ToString() != ) decimal gridColumn2 = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle, View.ColumnsMinValue); decimal gridColumn1 = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle, View.ColumnsMaxValue); if (gridColumn2 AverValue | AverValue gridColumn1) if (!ht.ContainsKey(pic) ht.Add(pic, GetImage(1); e.Value = htpic; / / 由資源文件獲取圖片/ / / 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);/ / 動態(tài)根據(jù)條件設置行樣式/ / / 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.ColumnsneedAlert); if (needAlert != null & needAlert != DBNull.Value & needAlert.ToString().Trim() != 0 & View.GetRowCellValue(e.RowHandle, View.ColumnsValue) != DBNull.Value) decimal AverValue = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle, View.ColumnsValue); object MinValue = View.GetRowCellValue(e.RowHandle, View.ColumnsMinValue); object MaxVlaue = View.GetRowCellValue(e.RowHandle, View.ColumnsMaxValue); 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 中顏色選擇控件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 = dve.ListSourceRowIndexColor.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; dve.ListSourceRowIndexColor = Common.RGB_HEX(colorVal.ToArgb(); 四、關于 GridControl 驗證示例/*/ / 初始化GridView，綁定數(shù)據(jù)/ / private void GridViewBindData(string parentId)this.gridView1.Columns.Clear();this.FDs= areaSetupActionHelper.getDsRegionByParentId(parentId);this.gridCArea.DataSource =this.FDs.Tables0.DefaultView;
