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=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

   /// <summary>/// 自定义进度条列/// </summary>/// <param name="view"></param>/// <param name="fieldName">列的字段名</param>/// <param name="warningValue"></param>/// <param name="lessColor"></param>/// <param name="greaterColor"></param>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 == 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);}}}
