gridView1.BeginSort();//事务开始 gridView1.ClearSorting();事务失败回滚 gridView1.Columns[“LICENSE_NO”].SortOrder = DevExpress.Data.ColumnSortOrder.Ascending;//功能代码 gridView1.EndSort();事务成功结束

Run Designer——>Column（需要设置的列）——>ColumnEdit——>new(在这里选择你要的是什么样的下拉框) 设置为不可编辑，只能选择： Run Designer——>Column（需要设置的列）——>ColumnEdit下选栏——>TextEditStyle——>DisableTextEditor

整个页面单元格禁止编辑：bandedGridView2.OptionsBehavior.Editable = false; 某列单元格禁止编辑： bandedGridView2.Columns[1].OptionsColumn.AllowEdit = false;//Columns[i],i为列号（第几列）

View->OptionsBehavior->EditorShowMode 设置为：Click

(1)、gridView.AddNewRow()

(2)、实现 gridView_InitNewRow 事件

gridView.populateColumns();

(1)、View->OptionsBehavior->EditorShowMode 设置为：Click

(2)、View->OptionsBehavior->Editable 设置为：false

设置 Run Design->OptionsMenu->EnableColumnMenu 设置为：false

设置 Run Design->OptionsView->ShowGroupPanel 设置为：false

设置 Run Design->OptionsCustomization->AllowFilter 设置为：false

方法如下：

//When no Records Are Being Displayed

private void gridView1_CustomDrawEmptyForeground(object sender, CustomDrawEventArgs e)

{

//方法一（此方法为GridView设置了数据源绑定时，可用）

ColumnView columnView = sender as ColumnView;

BindingSource bindingSource = this.gridView1.DataSource as BindingSource;

if(bindingSource.Count == 0)

{

string str = “没有查询到你所想要的数据!”;

Font f = new Font(“宋体”, 10, FontStyle.Bold);

Rectangle r = new Rectangle(e.Bounds.Top + 5, e.Bounds.Left + 5, e.Bounds.Right - 5, e.Bounds.Height - 5);

e.Graphics.DrawString(str, f, Brushes.Black, r); }

//方法二（此方法为GridView没有设置数据源绑定时，使用，一般使用此种方 法）

if (this._flag)

{ if (this.gridView1.RowCount == 0)

{ string str = “没有查询到你所想要的数据!”; Font f = new Font(“宋体”, 10, FontStyle.Bold);

Rectangle r = new Rectangle(e.Bounds.Left + 5, e.Bounds.Top + 5, e.Bounds.Width - 5, e.Bounds.Height - 5);

e.Graphics.DrawString(str, f, Brushes.Black, r); } } }

设置 this.gridView.OptionsView.ColumnAutoWidth = false;

…列表宽度自适应内容

gridview1.BestFitColumns();

设置 this.gridView.MoveFirst()

设置 this.gridView.MoveNext()

设置 this.gridView.MoveLast()

this.gridView1.FocusRectStyle = DevExpress.XtraGrid.Views.Grid.DrawFocusRectStyle.RowFocus;

this.gridView1.OptionsBehavior.Editable = false;

this.gridView1.OptionsSelection.EnableAppearanceFocusedCell = false;

private void gvPayList_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e) { e.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Far; if (e.Info.IsRowIndicator) { if (e.RowHandle >= 0) { e.Info.DisplayText = (e.RowHandle + 1).ToString(); } else if (e.RowHandle < 0 && e.RowHandle > -1000) { e.Info.Appearance.BackColor = System.Drawing.Color.AntiqueWhite; e.Info.DisplayText = “G” + e.RowHandle.ToString(); } } }

设置 gridView1.OptionsCustomization.AllowColumnMoving = false;

设置 gridView1.OptionsCustomization.AllowSort = false;

设置 gridView1.OptionsCustomization.AllowColumnResizing = false;

设置Columns，选择要固定的列。设置Fixed属性，可以选择：固定在左边、固定在右边、不固定。

OptionsView>OptionsBehavior>AutoExpandAllGroups = True 选择要分组的列，将GroupIndex属性设置为0

}

///初始化表格

using DevExpress.XtraGrid.Columns; using DevExpress.XtraGrid.Views.Base; using DevExpress.XtraGrid.Views.BandedGrid; using DevExpress.XtraEditors.Repository; private void InitGrid() { // advBandedGridView1是表格上的默认视图，注意这里声明的是：BandedGridView BandedGridView view = advBandedGridView1 as BandedGridView; view.BeginUpdate(); //开始视图的编辑，防止触发其他事件 view.BeginDataUpdate(); //开始数据的编辑 view.Bands.Clear();

具体可看

private void gridview_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e) {

e.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Far; if (e.Info.IsRowIndicator) { if (e.RowHandle >= 0) { e.Info.DisplayText = (e.RowHandle + 1).ToString(); } else if (e.RowHandle < 0 && e.RowHandle > -1000) { e.Info.Appearance.BackColor = System.Drawing.Color.AntiqueWhite; e.Info.DisplayText = “G” + e.RowHandle.ToString(); } }

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 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[]”));

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”); }

}

gridView1.Columns[0].AppearanceHeader.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center; gridView1.Columns[0].AppearanceCell.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;

列名.OptionsFilter.FilterPopupMode= DevExpress.XtraGrid.Columns.FilterPopupMode.CheckedList

this.gridView1.Appearance.OddRow.BackColor = Color.White; // 设置奇数行颜色 // 默认也是白色 可以省略 this.gridView1.OptionsView.EnableAppearanceOddRow = true; // 使能 // 和和上面绑定 同时使用有效 this.gridView1.Appearance.EvenRow.BackColor = Color.WhiteSmoke; // 设置偶数行颜色 this.gridView1.OptionsView.EnableAppearanceEvenRow = true; // 使能 // 和和上面绑定 同时使用有效

gridView1.OptionsView.ShowGroupPanel=false;

sValue=Table.Rows[gridView1.FocusedRowHandle][FieldName].ToString();

gridView1.OptionsBehavior.Editable=false;

gridView1.OptionsDetail.EnableMasterViewMode=false;

gridView1.GroupPanelText=“柳生飘絮”;

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.

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

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”;

gridView1.Columns[0].AppearanceHeader.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center; gridView1.Columns[0].AppearanceCell.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;

gridView1.Columns[0].OptionsFilter.AllowAutoFilter = false; gridView1.Columns[0].OptionsFilter.AllowFilter = false; gridView1.Columns[0].OptionsFilter.ImmediateUpdateAutoFilter = false;

gridView1.Columns[0].Fixed= DevExpress.XtraGrid.Columns.FixedStyle.Left;

string ss=gridView1.GetRowCellDisplayText(0, gridView1.Columns[0]); string ss = gridView1.GetRowCellValue(0, gridView1.Columns[0]);

gridView1.SetRowCellValue(0, gridView1.Columns[0], “123”);

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);

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(); }

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(); } } }

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

}

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 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; }
