DEV控件：gridControl常用属性设置,第1张

概述  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   gri

 

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;

  

   

@H_403_314@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 *** 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(" *** 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"];

                 }

@H_819_1502@             }

         }

     }

}

  

/// <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();

  

@H_502_2248@    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;

}

/**//// <summary>

/// grIDVIEw单元格验证的相关处理程序

    }

    if(this.grIDVIEw1.FocusedColumn.FIEldname =="reg_name")

    {     

     Regex reg=newRegex(@"[\u4e00-\u9fa5]{1,20}");

     Match m=reg.Match(e.Value.ToString().Trim());

     if(m.Length != e.Value.ToString().Trim().Length)

     {

      e.ValID =false;

      e.ErrorText ="区划名称应为汉字\n长度为1至20";

     }

    }

}

  

privatevoID grIDVIEw1_InvalIDValueException(objectsender,InvalIDValueExceptionEventArgs e)

{

    if(MyDialog.Alert("　您所填写的内容不符合规则\n　要放弃您刚才对此项所做的更改吗？","您所编辑的内容不符合规则",MessageBoxIcon.Warning) == DialogResult.Yes)

    {

     e.ExceptionMode = ExceptionMode.Ignore;

    }

}

  

/**//// <summary>

/// grIDVIEw行验证的相关处理程序

stringregID = this.grIDVIEw1.GetRowCellValue(e.RowHandle,"reg_ID").ToString().Trim();

stringregname = this.grIDVIEw1.GetRowCellValue(e.RowHandle,"reg_name").ToString().Trim();

if ( regID.Length < 1)

{

     e.ValID =false;

     this.grIDVIEw1.SetColumnError(this.grIDVIEw1.Columns["reg_ID"],"请填写区划编号!",DevExpress.XtraEditors.DXErrorProvIDer.ErrorType.Default);

      // e.ErrorText = "区划名称不能为空!";

    }

    if(regname.Length < 1)

    {

     e.ValID =false;

     this.grIDVIEw1.SetColumnError(this.grIDVIEw1.Columns["reg_name"],"区划名称不能为空!",DevExpress.XtraEditors.DXErrorProvIDer.ErrorType.Default);

    }

}

  

privatevoID grIDVIEw1_InvalIDRowException(objectsender,DevExpress.XtraGrID.VIEws.Base.InvalIDRowExceptionEventArgs e)
