DEV控件：gridControl常用属性设置

标签：it

分类：编程语言

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]);
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.GridColumnCol1=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 voidgridview_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 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)
       {
           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(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:
    private voidgridView1_InitNewRow(object sender,DevExpress.XtraGrid.Views.Grid.InitNewRowEventArgs e)
    {
       ColumnView View = sender asColumnView;
       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 = newDataTable("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 = newFileStream(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 voidgridView1_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DevExpressWinform 4个代码片段：

一、GridControl的删除操作

privatevoid 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

Hashtableht = new Hashtable();

privatevoid 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);
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>
/// <paramname="e"></param>
private void gridView6_RowStyle(objectsender, 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

privatevoid gvMapColor_CustomUnboundColumnData(object sender,DevExpress.XtraGrid.Views.Base.CustomColumnDataEventArgs e)
{
     GridView view = sender as GridView;
     DataView dv = view.DataSource asDataView;
     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(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 = 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 = newRepositoryItemMemoExEdit();

    TreeListNode node =this.treelArea.FocusedNode.ParentNode;
    string fid =node==null?"0":node.GetValue("RegID").ToString().Trim();
    DataSet ds =areaSetupActionHelper.getDsRegionByParentId(fid);
    RepositoryItemLookUpEditlookUEParent_Id = new RepositoryItemLookUpEdit();
    lookUEParent_Id.Columns.Add(newLookUpColumnInfo("reg_id", 40, "区划编号"));
    lookUEParent_Id.Columns.Add(newLookUpColumnInfo("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;
}
/// <summary>
/// gridView单元格验证的相关处理程序
/// </summary>
/// <param name="sender"></param>
/// <paramname="e"></param>
private voidgridView1_ValidatingEditor(object sender,DevExpress.XtraEditors.Controls.BaseContainerValidateEditorEventArgs e)
{
if (e.Valid == false&this.gridView1.FocusedColumn.FieldName =="reg_id")
{
      e.ErrorText = "区划编号不合法！\n应为父区划编号加2～3位数据组成！";
     }
    if(this.gridView1.FocusedColumn.FieldName == "reg_name")
    {
      Regex reg=newRegex(@"[\u4e00-\u9fa5]{1,20}");
     Matchm=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(object sender,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",MessageBoxButtons.YesNo, MessageBoxIcon.Warning) == DialogResult.Yes)
    {
     e.ExceptionMode = ExceptionMode.Ignore;
    }
}

///<summary>
/// gridView行验证的相关处理程序
/// </summary>
private void gridView1_ValidateRow(object sender,DevExpress.XtraGrid.Views.Base.ValidateRowEventArgs e)
{
string regid = this.gridView1.GetRowCellValue(e.RowHandle,"reg_id").ToString().Trim();
string regName = 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(object sender,DevExpress.XtraGrid.Views.Base.InvalidRowExceptionEventArgs e)
{

    if (e.RowHandle >= 0)
    {
     if(this.gridView1.GetRowCellValue(e.RowHandle, this.gridView1.Columns["reg_id"]).ToString().Trim()== "" || this.gridView1.GetRowCellValue(e.RowHandle,this.gridView1.Columns["reg_name"]).ToString().Trim() =="")
     {
      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",MessageBoxButtons.YesNo, MessageBoxIcon.Warning) == DialogResult.Yes)
      {
       e.ExceptionMode =ExceptionMode.Ignore;
      }
      else
      {
       e.ExceptionMode =ExceptionMode.NoAction;
      }
     }
    }
    else
    {
     e.ExceptionMode =ExceptionMode.Ignore;
    }
}

关于XtraGrid的使用（GridControl小结）来源：51编程网发布时间：2010-04-19Hits：146
DevExpress XtraGrid的使用（AspxGridControl小结）收藏

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
