C#|winform Dev GridView 控件常用属性总结 DevExpress|控件|winform

Dev GridControl GridView常用属性 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=https://www.it610.com/article/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="奔跑ing";
6.设置数据源:
gridControl1.DataSource = dt;
7.读写拷贝权限设置:
只读不可拷贝：
ColumnView.OptionsBehavior.Editable = False
只读可拷贝:
ColumnView.OptionsBehavior.Editable = True
OptionsColumn.AllowEdit = True
OptionsColumn.ReadOnly = True
e.g.
gv_order.OptionsBehavior.Editable = true;
gv_order.Columns["Value"].OptionsColumn.AllowEdit = true;
gv_order.Columns["Value"].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:
gridView1.SetRowCellValue(0, gridView1.Columns[0], "123");
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、如何让各列头禁止移动？
设置 gridView1.OptionsCustomization.AllowColumnMoving = false

16、如何让各列头禁止排序？
设置 gridView1.OptionsCustomization.AllowSort = false

17、如何禁止各列头改变列宽？
设置 gridView1.OptionsCustomization.AllowColumnResizing = false
18 根据数据样式显示不同的效果

private void gridView1_RowCellStyle(object sender, DevExpress.XtraGrid.Views.Grid.RowCellStyleEventArgs e) { string accountQuantity = gridView1.GetRowCellValue(e.RowHandle, "ACCOUNT_QUANTITY").ToString(); string actualQuantity = gridView1.GetRowCellValue(e.RowHandle, "ACTUAL_QUANTITY").ToString(); if (accountQuantity != actualQuantity) { // e.Appearance.BackColor = Color.Red; //改变背景色 e.Appearance.ForeColor = Color.Red; //改变字体颜色 } if (e.DisplayText.ToString().Equals("0001-01-01")) { e.DisplayText = string.Empty; } if (e.DisplayText.ToString().Equals("0001-01-01 00:00:00")) { e.DisplayText = string.Empty; } }

19，显示进度条

/// /// 自定义进度条列 /// /// /// 列的字段名 /// /// /// public static void CustomProgressBarColumn(DevExpress.XtraGrid.Views.Grid.GridView view, string fieldName, int warningValue, Brush lessColor , Brush greaterColor) { var col = view.Columns[fieldName]; if (col == null) return; col.AppearanceCell.Options.UseTextOptions = true; col.AppearanceCell.TextOptions.HAlignment = HorzAlignment.Center; view.CustomDrawCell += (s, e) => { if (e.Column.FieldName == fieldName) { DrawProgressBar(e,warningValue,lessColor,greaterColor); e.Handled = true; DrawEditor(e); } }; } static void DrawProgressBar(DevExpress.XtraGrid.Views.Base.RowCellCustomDrawEventArgs e, int warningValue , Brush lessColor, Brush greaterColor) { double percent = e.CellValue =https://www.it610.com/article/= null ? 0 : (double)e.CellValue; int width = (int)(percent * e.Bounds.Width); Rectangle rect = new Rectangle(e.Bounds.X, e.Bounds.Y, width, e.Bounds.Height); Brush b = Brushes.Green; if (greaterColor != null) { b = greaterColor; } if (percent*100< warningValue) { if (lessColor == null) { b = Brushes.Red; } else { b = lessColor; } } e.Graphics.FillRectangle(b, rect); } static void DrawEditor(DevExpress.XtraGrid.Views.Base.RowCellCustomDrawEventArgs e) { GridCellInfo cell = e.Cell as GridCellInfo; Point offset = cell.CellValueRect.Location; BaseEditPainter pb = cell.ViewInfo.Painter as BaseEditPainter; AppearanceObject style = cell.ViewInfo.PaintAppearance; if (!offset.IsEmpty) cell.ViewInfo.Offset(offset.X, offset.Y); try { pb.Draw(new ControlGraphicsInfoArgs(cell.ViewInfo, e.Cache, cell.Bounds)); } finally { if (!offset.IsEmpty) { cell.ViewInfo.Offset(-offset.X, -offset.Y); } } }
