DEV控件：gridControl常用属性设置 
  
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-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(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=
new
DevExpress.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(
object
sender,                            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
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();
           
}
       
}
    
}
   
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、Advanced BandedView、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<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(
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;
        
}
  
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, 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"
);
  
}
  
  
}
  
#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.CustomColumnDataEventArgs 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"
]));
             
object
MinValue = View.GetRowCellValue(e.RowHandle, View.Columns[
"MinValue"
]);
             
object
MaxVlaue = 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);
     
return
DevExpress.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"
]));
             
object
MinValue = View.GetRowCellValue(e.RowHandle, View.Columns[
"MinValue"
]);
             
object
MaxVlaue = 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 =
new
RepositoryItemTextEdit();
    
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 =
new
RepositoryItemLookUpEdit();
    
lookUEParent_Id.Columns.Add(
new
LookUpColumnInfo(
"reg_id"
, 40,
"区划编号"
));
    
lookUEParent_Id.Columns.Add(
new
LookUpColumnInfo(
"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;
}
