二、如何新增一条记录

(1)、gridView.AddNewRow()

(2)、实现gridView_InitNewRow事件

三、如何解决GridControl记录能获取而没有显示出来的问题

gridView.populateColumns();

四、如何让行只能选择而不能编辑（或编辑某一单元格）

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

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

五、如何禁用GridControl中单击列弹出右键菜单

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

六、如何隐藏GridControl的GroupPanel表头

七、如何禁用GridControl中列头的过滤器

过滤器如下图所示：

使用方法总结" v:shapes="图片_x0020_1">

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

八、如何在查询得到0条记录时显示自定义的字符提示/显示

如图所示：

使用方法总结" v:shapes="图片_x0020_2">

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？

设置 this.gridView.MoveFirst()

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？

设置gridView1.OptionsCustomization.AllowColumnMoving = false;

十六、如何让各列头禁止排序？

设置gridView1.OptionsCustomization.AllowSort = false;

十七、如何禁止各列头改变列宽？

设置gridView1.OptionsCustomization.AllowColumnResizing = false;

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

/**////

/// 初始化GridView，绑定数据
/// </summary>
/// <param name="parentId"></param>
private void GridViewBindData(string parentId)
{
this.gridView1.Columns.Clear();

    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

自定义焦点行的方法： gridView_bcode.FocusedRowHandle = focuseRowInt; //通过设置GridView 的FocusedRowHandle属性
 
view plaincopy to clipboardprint?
//获取焦点行任意单元格的数据    
ColumnView cv = (ColumnView)gridControl_Gongzi.FocusedView;//重新获取此ID 否则无法从表头连删获取不到id
