C#中gridView常用属性和技巧介绍(转)

2022年07月19日122del
复制代码
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)  
   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=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 void gridview_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 void datagridviewdel_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(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、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  
        private void 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;  
                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 = new FileStream(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 void gridView1_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.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);  
     return DevExpress.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"]));  
             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  
   
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  
   
/// <summary>  
/// 初始化GridView,绑定数据  
/// </summary>  
/// <param name="parentId"></param>  
private void GridViewBindData(string parentId)  
{  
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+"file://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 = node==null?"0":node.GetValue("RegID").ToString().Trim();  
    DataSet ds = areaSetupActionHelper.getDsRegionByParentId(fid);  
    RepositoryItemLookUpEdit lookUEParent_Id = new RepositoryItemLookUpEdit();  
    lookUEParent_Id.Columns.Add(new LookUpColumnInfo("reg_id", 40, "区划编号"));  
    lookUEParent_Id.Columns.Add(new LookUpColumnInfo("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

}  
   
    
   
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     
                        int focusedhandle = cv.FocusedRowHandle;     
                        object rowIdObj = gridView1.GetRowCellValue(focusedhandle, "id");     
                        if (DBNull.Value != rowIdObj)     
                        {     
                            FocusedRow_id = Convert.ToInt32(rowIdObj);     
                        }    
//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  
                        int focusedhandle = cv.FocusedRowHandle;  
                        object rowIdObj = gridView1.GetRowCellValue(focusedhandle, "id");  
                        if (DBNull.Value != rowIdObj)  
                        {  
                            FocusedRow_id = Convert.ToInt32(rowIdObj);  
                        }  
 view plaincopy to clipboardprint?  
//当数据发生变化时执行      
     private void gridView1_CellValueChanged(object sender, CellValueChangedEventArgs e)     
     {     
         int intRowHandle = e.RowHandle;     
         FocusedRow_bumen = Convert.ToString(gridView1.GetRowCellValue(intRowHandle, "bumen"));     
         FocusedRow_xingming = Convert.ToString(gridView1.GetRowCellValue(intRowHandle, "xingming"));     
         //FocusedRow_jibengongzi = Convert.ToDecimal(gridView1.GetRowCellValue(intRowHandle, "jibengongzi"));

 C#中GridView格式化字符串,其实就是使用DataFromatString的方法,那么现在就向你介绍具体的内容和实现的实例应用,希望对你有所帮助。

    在我们从业务逻辑层获得数据实体时候,接下来的事情就是要绑定到控件中。数据实体中的一些字段可以直接绑定到界面中,但是有一些字段需要重新格式化格式。比如货币单位字段,需要显示货币符号和每隔三位显示分隔符;再比如日期字段,数据库中存放的是日期和时间,但是在界面上需要按照XXXX年XX月XX日的格式显示。这时候我们就用到了DataFormatString属性。

复制代码
﹤asp:GridView ID="grvResult" runat="server"    
AutoGenerateColumns="False" Width="100%"﹥    
﹤Columns﹥    
﹤asp:BoundField HeaderText="预定日期"    
DataField="OperationDate" DataFormatString="{   
0:yyyy-MM-dd}" HtmlEncode="False"﹥    
﹤/asp:BoundField﹥      
﹤asp:BoundField HeaderText="订单总计"    
DataField="TotalRate" DataFormatString="{   
0:C}" HtmlEncode="False"﹥    
﹤/asp:BoundField﹥    
﹤/Columns﹥    
﹤/asp:GridView﹥ 
复制代码

例如上面的代码展示了日期和货币两种绑定方式。DataFormatString中的{0}是固定的格式,这和String.Fromat(“{0}”, someString)中的{0}是一个用法,表示绑定上下文的参数索引编号。然后,在后面加入C#格式化字符串,具体的使用方法可以参考MSDN。

    C#中GridView格式化字符串注意以下几点

    1. 在GridView中的asp:BoundField使用DataFormatString必须设置属性HtmlEncode="False",否则不起作用。

    2. 如果需要使用日期类型的格式化字符串,必须数据实体中对应的字段也应该日起类型的。

    3. 格式化字符串C代表货币单位,需要绑定的数据类型应该是数字类型的。如果是字符串类型的不起作用,需要手动添加格式化字符串为DataFormatString="¥{0:C}"。

    C#中GridView格式化字符串的基本情况就向你介绍到这里,希望对你学习和理解C#中GridView格式化字符串有所帮助。

   1、在gridview中一直对“删除”不是很理解,在ASP的模式下面,这个删除链接应该有一个行ID标识,以便程序知道删除那一行,或针对这行做一些处理,然而在ASP.net里面也可以用,但是不是最好的。 
    2、应该用LinkButton的各种属性,这时候非常方面,而且便于理解。这样不用选中一行(gridview.selectedRow 提供定位信息),然后再点击某种操作了。 
    请注意 CommandName, CommandArgument 和 LinkButton的名字 CommandArgument 的对应关系。 
    有了 CommandName 就知道是那个LinkButton控件。 
    有了 CommandArgument(和行的ID绑定),就知道要处理那一行。 
    swicth(CommandName) 
    case "sort":{} 
    case “delete”:{}
