如图所示：

DevExpress GridControl使用方法总结

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);

}

九、如何显示水平滚动条？

设置 this .gridView.OptionsView.ColumnAutoWidth = false ;

十、如何定位到第一条数据/记录？

十一、如何定位到下一条数据/记录？

设置 this .gridView.MoveNext()

十二、如何定位到最后一条数据/记录？

设置 this .gridView.MoveLast()

十三、设置成一次选择一行，并且不能被编辑

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

this .gridView1.OptionsBehavior.Editable = false ;

this .gridView1.OptionsSelection.EnableAppearanceFocusedCell = false ;

十四、如何显示行号？

this .gridView1.IndicatorWidth = 40;

//显示行的序号

private void gridView1_CustomDrawRowIndicator( object sender, RowIndicatorCustomDrawEventArgs e)

{

if (e.Info.IsRowIndicator && e.RowHandle>=0)

{

e.Info.DisplayText = (e.RowHandle + 1).ToString();

}

十五、如何让各列头禁止移动？

DEV控件：gridControl常用属性设置

2011-01-19 09:50

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= "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

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-PlaceEditor 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(将0行0列的单元格赋值123)

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

13.手动添加dev的列

DevExpress.XtraGrid.Columns.GridColumn Col1=newDevExpress.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_CustomDrawRowIndicator(objectsender,                           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 voiddatagridviewdel_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)

{

intiSelectRowCount = Mydgv.SelectedRowsCount;

if (iSelectRowCount > 0)

{

Mydgv.DeleteSelectedRows();

}

16. 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 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

}

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、AdvancedBandedView、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gridcontrolview 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 voidshowData(List<Employee > 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(stringimagePath)

{

FileStreamfiles = new FileStream(imagePath, FileMode.Open);

byte []imgByte = new byte [files.Length ];

files.Read(imgByte, 0, imgByte.Length);

files.Close();

returnimgByte;

}

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, ValidateRowEventArgse)

{

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" );

}

#endregion

调用gridview.UpdateCurrentRow()方法执行检查

最常用的DevExpress Winform 4个代码片段：

一、GridControl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" ].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.CustomColumnDataEventArgse)

{

GridView 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.Columns[ "Value" ]) != DBNull.Value)

{

decimal AverValue = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle,View.Columns[ "Value" ]));

objectMinValue = View.GetRowCellValue(e.RowHandle,View.Columns[ "MinValue" ]);

objectMaxVlaue = View.GetRowCellValue(e.RowHandle,View.Columns[ "MaxValue" ]);

if (MinValue != DBNull.Value & MinValue != null & 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.GetRowCellValue(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"></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);

returnDevExpress.XtraEditors.Controls.ByteImageConverter.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)

{

GridView 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.Columns[ "Value" ]) != DBNull.Value)

{

decimal AverValue = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle, View.Columns[ "Value" ]));

objectMinValue = View.GetRowCellValue(e.RowHandle,View.Columns[ "MinValue" ]);

objectMaxVlaue = View.GetRowCellValue(e.RowHandle,View.Columns[ "MaxValue" ]);

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 中颜色选择控件

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 =dv[e.ListSourceRowIndex][ "Color" ].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;

dv[e.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="parentId"></param>

private void GridViewBindData( string parentId)

{

this .gridView1.Columns.Clear();

this .FDs= areaSetupActionHelper.getDsRegionByParentId(parentId);

this .gridCArea.DataSource = this .FDs.Tables[0].DefaultView;

this .gridView1.Columns[ "id" ].VisibleIndex =-1;

this .gridView1.Columns[ "childCounts" ].VisibleIndex= -1;

this .gridView1.Columns[ "reg_id" ].Caption = "区划编号" ;

this .gridView1.Columns[ "reg_name" ].Caption = "区划名称" ;

this .gridView1.Columns[ "parent_id" ].Caption = "父区划编号" ;

this .gridView1.Columns[ "reg_desc" ].Caption = "区划描述" ;

this .gridView1.Columns[ "parent_id" ].ImageIndex =1;

this .gridView1.Columns[ "reg_desc" ].ImageIndex = 0;

RepositoryItemTextEdit textEditReg_Id = newRepositoryItemTextEdit();

textEditReg_Id.Mask.EditMask =parentId+ "\\d{2,3}" ;

textEditReg_Id.Mask.MaskType =DevExpress.XtraEditors.Mask.MaskType.Regular;

this .gridView1.Columns[ "reg_id" ].ColumnEdit =textEditReg_Id;

this .gridView1.Columns[ "reg_desc" ].ColumnEdit= new RepositoryItemMemoExEdit();

TreeListNode node = this .treelArea.FocusedNode.ParentNode;

string fid =node== null ? "0" :node.GetValue( "RegID" ).ToString().Trim();

DataSet ds =areaSetupActionHelper.getDsRegionByParentId(fid);

RepositoryItemLookUpEdit lookUEParent_Id = newRepositoryItemLookUpEdit();

lookUEParent_Id.Columns.Add(newLookUpColumnInfo( "reg_id" , 40, "区划编号" ));

lookUEParent_Id.Columns.Add(newLookUpColumnInfo( "reg_name" , 40, "区划名称" ));

lookUEParent_Id.DataSource = ds.Tables[0].DefaultView;

lookUEParent_Id.ValueMember = "reg_id" ;

lookUEParent_Id.DisplayMember = "reg_id" ;

this .gridView1.Columns[ "parent_id" ].ColumnEdit =lookUEParent_Id;

}

/**/ /// <summary>
