C#中gridView常用屬性和技巧介紹

1.隱藏最上面的GroupPanel 
  gridView1.OptionsView.ShowGroupPanel=false; 
  
2.得到當前選定記錄某字段的值 
  sValue=Table.Rows[gridView1.FocusedRowHandle][FieldName].ToString(); 
  
3.數據只讀 
  gridView1.OptionsBehavior.Editable=false; 
  
4.不顯示MasterDetailView 
  gridView1.OptionsDetail.EnableMasterViewMode=false; 
  
5.修改最上面的GroupPanel內容 
   gridView1.GroupPanelText="柳生飄絮"; 
  
6.設置數據源: 
   gridControl1.DataSource = dt; 
   綁定每一列的FiledName--屬性 
   對於Oracle數據庫,所有的在設計器裏寫的程序中的字段名必須大寫,否則可能綁定不上字段,sqlserver沒有這個限制. 
  
7.讀寫拷貝權限設置 
  只讀不可拷貝： 
    ColumnViewOptionsBehavior.Editable = False 
  
  只讀可拷貝: 
    ColumnViewOptionsBehavior.Editable = True 
    OptionsColumn.AllowEdit = True 
    OptionsColumn.ReadOnly = True 
  
  可編輯: 
    ColumnViewOptionsBehavior.Editable = True 
    OptionsColumn.AllowEdit = True 
    OptionsColumn.ReadOnly = False 
  
8.模板列的設置: 
  到Columns中，在他的屬性中找到ColumnEdit. 
  以LookUpEdit爲例： 
  首先從Designer左邊菜單In-Place Editor Repository中添加LookUpEdit.取名爲Re1.然後.在他的Columns屬性中添加3列.Caption依次爲:編號,姓名,性別.FieldName依次爲:FID,FNAME,FSEX.然後將Re1的NullText設置成空. 
　　AutoSearchColumnIndex屬性設置爲2.ImmediatePopup屬性設置爲True. 
　　SearchMode設置爲OnlyInPopup. 
　　然後將這個模板列附加到我們上面提到的列1(也就是將列1的ColumnEdit屬性設成Re1) 
　　最後我們還要在代碼裏面給Re1綁定數據源和顯示項. 
         Re1.DataSource = DALUse.Query("select fid,fname,fsex from dual").Tables[0]; 
         Re1.DisplayMember = "FSEX"; 
         Re1.ValueMember = "FNAME"; 
  
   
  
9.設某一列文字和標題局中顯示                   
   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動篩選功能(Filter)                   
   gridView1.Columns[0].OptionsFilter.AllowAutoFilter = false; 
   gridView1.Columns[0].OptionsFilter.AllowFilter = false;                 
   gridView1.Columns[0].OptionsFilter.ImmediateUpdateAutoFilter = false; 
  
  
11.設置凍結列(左凍結) 
  gridView1.Columns[0].Fixed= DevExpress.XtraGrid.Columns.FixedStyle.Left; 
  
  
12.得到單元格數據(0行0列) 
   string ss=gridView1.GetRowCellDisplayText(0, gridView1.Columns[0]); 
   string ss = gridView1.GetRowCellValue(0, gridView1.Columns[0]); 
  
  
13.設置單元格數據(將0行0列的單元格賦值123) 
   gridView1.SetRowCellValue(0, gridView1.Columns[0], "123"); 
  
  
13.手動添加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.設置自動增加的行號,需要先添加給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.刪除: (修改了dgvdel裏的datagridviewdel方法) 
    public static void datagridviewdel_Dev(DevExpress.XtraGrid.Views.Grid.GridView Mydgv) 
    { 
       if (MessageBox.Show("你確定要刪除選中的記錄嗎？", "刪除提示", MessageBoxButtons.YesNo,               MessageBoxIcon.Warning, MessageBoxDefaultButton.Button2, 0, false) == DialogResult.Yes) 
       { 
           int iSelectRowCount = Mydgv.SelectedRowsCount; 
           if (iSelectRowCount > 0) 
           { 
             Mydgv.DeleteSelectedRows(); 
           } 
       } 
    } 
   
16. 新增: (對於新增,其本身的AddNewRow方法就可以做到) 
    private void btn_add_Click(object sender, EventArgs e) 
    {   
       gridView1.AddNewRow();    
     } 
    具體如果對於新加行還有什麼特別的設置,可以在它gridView1_InitNewRow事件中填寫: 
    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])); //複製最後一行的數據到新行 
  
            View.SetRowCellValue(e.RowHandle, View.Columns[1], gridView1.GetRowCellValue(gridView1.GetRowHandle(gridView1.RowCount - 2), gridView1.Columns[1])); //複製最後一行的數據到新行 
  
    } 
  
  
17. 保存 (第三方控件提供的RefreshData和RefreshDataSource方法對於保存數據都不好使,最後還是使用了Dgvsave的datagridviewsave方法,用這個方法就可以) 
  
  
18.特效：gridcontrol中有5種view 型式，普通的是gridview，然後分別爲cardview、BandedView、Advanced BandedView、LayoutView；共5種。 
  1）、view組中把OptionView下的viewmode 設置成“Carousel”就達到這種“旋轉木馬”式的gridcontrol view 特效了 
  2）、layoutView1.OptionsCarouselMode.PitchAngle 這個屬性決定“旋轉木馬”的pitch angle 螺距角; 螺旋角; 螺旋升角; 俯仰角; 傾角; 節錐半角  
  3）、Roll Angle 屬性決定着傾側角度 
  4）、指定數據源，顯示數據： 
  //顯示數據 
        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; 
        } 
  
        //返回圖片的字節流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.檢查數據的有效性 
  在gridview的ValidateRow事件中加入檢查代碼： 
  #region 檢查數據 
  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"], "必須指定日期"); 
  } 
  
  } 
  #endregion 
  調用gridview.UpdateCurrentRow()方法執行檢查 
  
  
最常用的DevExpress Winform 4個代碼片段： 
  
一 、GridControl的刪除操作 
  
private void rILinkEditInfoDel_Click(object sender, EventArgs e) 
{ 
     if (XtraMessageBox.Show("請確定是否刪除當前記錄？", "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、綁定非數據表中列 
  
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> 
/// 由資源文件獲取圖片 
/// </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> 
/// 動態根據條件設置行樣式 
/// </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 中顏色選擇控件 
  
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、關於 GridControl 驗證示例 
  
/// <summary> 
/// 初始化GridView，綁定數據 
/// </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 = "區劃編號"; 
    this.gridView1.Columns["reg_name"].Caption = "區劃名稱"; 
    this.gridView1.Columns["parent_id"].Caption = "父區劃編號"; 
    this.gridView1.Columns["reg_desc"].Caption = "區劃描述"; 
    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, "區劃編號")); 
    lookUEParent_Id.Columns.Add(new LookUpColumnInfo("reg_name", 40, "區劃名稱")); 
    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; 
}

關於XtraGrid的使用（GridControl小結）來源：51編程網發佈時間：2010-04-19Hits：146 
DevExpress XtraGrid的使用（AspxGridControl小結）收藏 
  
自定義焦點行的方法： gridView_bcode.FocusedRowHandle = focuseRowInt; //通過設置GridView 的FocusedRowHandle屬性 
   
view plaincopy to clipboardprint? 
//獲取焦點行任意單元格的數據     
ColumnView cv = (ColumnView)gridControl_Gongzi.FocusedView;//重新獲取此ID 否則無法從表頭連刪獲取不到id    
                        int focusedhandle = cv.FocusedRowHandle;    
                        object rowIdObj = gridView1.GetRowCellValue(focusedhandle, "id");    
                        if (DBNull.Value != rowIdObj)    
                        {    
                            FocusedRow_id = Convert.ToInt32(rowIdObj);    
                        }   
//獲取焦點行任意單元格的數據  
ColumnView cv = (ColumnView)gridControl_Gongzi.FocusedView;//重新獲取此ID 否則無法從表頭連刪獲取不到id

                        object rowIdObj = gridView1.GetRowCellValue(focusedhandle, "id"); 
                        if (DBNull.Value != rowIdObj) 
                        { 
                            FocusedRow_id = Convert.ToInt32(rowIdObj); 
                        } 
 view plaincopy to clipboardprint? 
//當數據發生變化時執行

C#中GridView格式化字符串，其實就是使用DataFromatString的方法，那麼現在就向你介紹具體的內容和實現的實例應用，希望對你有所幫助。

在我們從業務邏輯層獲得數據實體時候，接下來的事情就是要綁定到控件中。數據實體中的一些字段可以直接綁定到界面中，但是有一些字段需要重新格式化格式。比如貨幣單位字段，需要顯示貨幣符號和每隔三位顯示分隔符;再比如日期字段，數據庫中存放的是日期和時間，但是在界面上需要按照XXXX年XX月XX日的格式顯示。這時候我們就用到了DataFormatString屬性。

﹤asp:GridView ID="grvResult" runat="server"   
AutoGenerateColumns="False" Width="100%"﹥   
﹤Columns﹥   
﹤asp:BoundField HeaderText="預定日期"   
DataField="OperationDate" DataFormatString="{  
0:yyyy-MM-dd}" HtmlEncode="False"﹥   
﹤/asp:BoundField﹥     
﹤asp:BoundField HeaderText="訂單總計"   
DataField="TotalRate" DataFormatString="{  
0:C}" HtmlEncode="False"﹥   
﹤/asp:BoundField﹥   
﹤/Columns﹥   
﹤/asp:GridView﹥

例如上面的代碼展示了日期和貨幣兩種綁定方式。DataFormatString中的{0}是固定的格式，這和String.Fromat(“{0}”, someString)中的{0}是一個用法，表示綁定上下文的參數索引編號。然後，在後面加入C#格式化字符串，具體的使用方法可以參考MSDN。

C#中GridView格式化字符串注意以下幾點

1. 在GridView中的asp:BoundField使用DataFormatString必須設置屬性HtmlEncode="False"，否則不起作用。

2. 如果需要使用日期類型的格式化字符串，必須數據實體中對應的字段也應該日起類型的。

3. 格式化字符串C代表貨幣單位，需要綁定的數據類型應該是數字類型的。如果是字符串類型的不起作用，需要手動添加格式化字符串爲DataFormatString="￥{0:C}"。

C#中GridView格式化字符串的基本情況就向你介紹到這裏，希望對你學習和理解C#中GridView格式化字符串有所幫助。

   1、在gridview中一直對“刪除”不是很理解，在ASP的模式下面，這個刪除鏈接應該有一個行ID標識，以便程序知道刪除那一行，或針對這行做一些處理，然而在ASP.net裏面也可以用，但是不是最好的。
    2、應該用LinkButton的各種屬性，這時候非常方面，而且便於理解。這樣不用選中一行（gridview.selectedRow 提供定位信息），然後再點擊某種操作了。
    請注意 CommandName, CommandArgument 和 LinkButton的名字 CommandArgument 的對應關係。
    有了 CommandName 就知道是那個LinkButton控件。
    有了 CommandArgument（和行的ID綁定），就知道要處理那一行。
    swicth(CommandName)
    case "sort":{}
    case “delete”：{}
