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[

].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>

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());
      
}
 
}
