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)
???stringss=gridView1.GetRowCellDisplayText(0,gridView1.Columns[0]);
???stringss = 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
??
????privatevoid 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)
????publicstatic 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,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)
????privatevoid btn_add_Click(objectsender,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:
????privatevoid gridView1_InitNewRow(objectsender,DevExpress.XtraGrid.Views.Grid.InitNewRowEventArgs e)
????{
???????ColumnView View = senderas 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.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
????????privatevoid 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;
????????????????stringimagePath = @"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[]
????????privatebyte[] getImageByte(stringimagePath) 
????????{
????????????FileStream files =new FileStream(imagePath,FileMode.Open);
????????????byte[] imgByte =new byte[files.Length ]; 
????????????files.Read(imgByte,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
??privatevoid gridView1_ValidateRow(objectsender,ValidateRowEventArgs e) 
??{
??GridView view = senderas 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
??
privatevoid rILinkEditInfoDel_Click(objectsender,EventArgs e) 
{ 
?????if(XtraMessageBox.Show("请确定是否删除当前记录？","警告",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();
??
privatevoid gridView6_CustomUnboundColumnData(objectsender,DevExpress.XtraGrid.Views.Base.CustomColumnDataEventArgs e)
{ 
?????GridView View = senderas GridView;
?????if(e.RowHandle >= 0) 
?????{
?????????objectneedAlert = 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)
?????????{
?????????????decimalAverValue = 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() != "")
?????????????{
?????????????????decimalgridColumn2 = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle,View.Columns["MinValue"]));
?????????????????decimalgridColumn1 = 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(intkey) 
{ 
?????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>
privatevoid gridView6_RowStyle(objectsender,DevExpress.XtraGrid.Views.Grid.RowStyleEventArgs e)
{ 
?????GridView View = senderas GridView;
?????if(e.RowHandle >= 0) 
?????{
?????????objectneedAlert = 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)
?????????{
?????????????decimalAverValue = 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() != "")
?????????????{
?????????????????decimalgridColumn2 = Convert.ToDecimal(MinValue); 
?????????????????decimalgridColumn1 = 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
??
privatevoid gvMapColor_CustomUnboundColumnData(objectsender,DevExpress.XtraGrid.Views.Base.CustomColumnDataEventArgs e)
{ 
?????GridView view = senderas GridView;
?????DataView dv = view.DataSourceas DataView;
?????if(e.IsGetData) 
?????{
?????????stringstrVal = 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>
privatevoid GridViewBindData(stringparentId) 
{ 
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;
????stringfid = node==null?"0":node.GetValue("RegID").ToString().Trim();
????DataSet ds = areaSetupActionHelper.getDsRegionByParentId(fid);
????RepositoryItemLookUpEdit lookUEParent_Id =new RepositoryItemLookUpEdit();
????lookUEParent_Id.Columns.Add(newLookUpColumnInfo("reg_id",40,"区划编号")); 
????lookUEParent_Id.Columns.Add(newLookUpColumnInfo("reg_name","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; 
}

?????e.ExceptionMode = ExceptionMode.Ignore;
????}
} 
??
/**//// <summary>
