DevExpress 小計 GridControl 隔行換行


摘自: http://www.cnblogs.com/yuerdongni/archive/2012/09/08/2676753.html

1、 如何解決單擊記錄整行選中的問題

View->OptionsBehavior->EditorShowMode 設置為:Click

 

2、 如何新增一條記錄

(1)、gridView.AddNewRow()

(2)、實現 gridView_InitNewRow 事件

 

3、如何解決 GridControl 記錄能獲取而沒有顯示出來的問題

gridView.populateColumns();

 

4、如何讓行只能選擇而不能編輯(或編輯某一單元格)

(1)、View->OptionsBehavior->EditorShowMode 設置為:Click

(2)、View->OptionsBehavior->Editable 設置為:false

 

5、如何禁用 GridControl 中單擊列彈出右鍵菜單

設置 Run Design->OptionsMenu->EnableColumnMenu 設置為:false

 

6、如何隱藏 GridControl 的 GroupPanel 表頭

設置 Run Design->OptionsView->ShowGroupPanel 設置為:false

 

7、如何禁用 GridControl 中列頭的過濾器 過濾器如下圖所示:    

設置 Run Design->OptionsCustomization->AllowFilter 設置為:false

 

 

8、如何在查詢得到 0 條記錄時顯示自定義的字符提示/顯示 如圖所示:

方法如下:

//When no Records Are Being Displayed

 

private void gridView1_CustomDrawEmptyForeground(object sender, CustomDrawEventArgs e)

 

{

 

//方法一(此方法為GridView設置了數據源綁定時,可用)

 

ColumnView columnView = sender as ColumnView;

 

BindingSource bindingSource = this.gridView1.DataSource as BindingSource;

 

if(bindingSource.Count == 0)

 

{

 

string str = "沒有查詢到你所想要的數據!";

 

Font f = new Font("宋體", 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(此方法為GridView沒有設置數據源綁定時,使用,一般使用此種方 法)

 

if (this._flag)

 

{ if (this.gridView1.RowCount == 0)

 

{ string str = "沒有查詢到你所想要的數據!"; Font f = new Font("宋體", 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); } } }

 

 

 

9、如何顯示水平滾動條?或

 

設置 this.gridView.OptionsView.ColumnAutoWidth = false;

 

 

 

.....列表寬度自適應內容

 

gridview1.BestFitColumns();

 

 

 

10、如何定位到第一條數據/記錄?

 

設置 this.gridView.MoveFirst()

 

 

 

11、如何定位到下一條數據/記錄? 設置 this.gridView.MoveNext()

 

 

 

12、如何定位到最后一條數據/記錄?

 

設置 this.gridView.MoveLast()

 

 

 

13、設置成一次選擇一行,並且不能被編輯

 

this.gridView1.FocusRectStyle = DevExpress.XtraGrid.Views.Grid.DrawFocusRectStyle.RowFocus;

 

this.gridView1.OptionsBehavior.Editable = false;

 

this.gridView1.OptionsSelection.EnableAppearanceFocusedCell = false;

 

 

 

14、如何顯示行號?   private void gvPayList_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)         {             e.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Far;             if (e.Info.IsRowIndicator)             {                 if (e.RowHandle >= 0)                 {                     e.Info.DisplayText = (e.RowHandle + 1).ToString();                 }                 else if (e.RowHandle < 0 && e.RowHandle > -1000)                 {                     e.Info.Appearance.BackColor = System.Drawing.Color.AntiqueWhite;                     e.Info.DisplayText = "G" + e.RowHandle.ToString();                 }             }         }

 

 

 

15、如何讓各列頭禁止移動?

 

設置 gridView1.OptionsCustomization.AllowColumnMoving = false;

 

16、如何讓各列頭禁止排序?

 

設置 gridView1.OptionsCustomization.AllowSort = false;

 

17、如何禁止各列頭改變列寬?

 

設置 gridView1.OptionsCustomization.AllowColumnResizing = false;

 

 

 

18.拖動滾動條時固定某一列

 

設置Columns,選擇要固定的列。設置Fixed屬性,可以選擇:固定在左邊、固定在右邊、不固定。

 

 

 

19.獲取選定行,指定列單元格的內容

 

      return gridView1.GetRowCellValue(pRows[0], ColumName).ToString ();

 

20.分組顯示

 

OptionsView>OptionsBehavior>AutoExpandAllGroups = True 選擇要分組的列,將GroupIndex屬性設置為0

 

21.格式化數據

 

       private void gvList_ValidatingEditor(object sender, DevExpress.XtraEditors.Controls.BaseContainerValidateEditorEventArgs e)         {             if (this.gvList.FocusedColumn.FieldName == "passQty")             {                 string passQty = e.Value.ToString().Trim();                 int receiveQty = orderDetailList[this.gvList.FocusedRowHandle].qty;                 if (!JXType.IsIntBigThanZero(passQty))                 {                     e.Valid = false;                     e.ErrorText = "合格數量必須為大於等於0小於等於接貨數量的整數!";                 }                 else                 {                     if (int.Parse(passQty) > receiveQty)                     {                         e.Valid = false;                         e.ErrorText = "合格數量必須為大於0小於等於接貨數量的整數!";                     }                 }             }

 

}

 

 

 

22.合並表頭

 

   ///初始化表格

 

using DevExpress.XtraGrid.Columns; using DevExpress.XtraGrid.Views.Base; using DevExpress.XtraGrid.Views.BandedGrid; using DevExpress.XtraEditors.Repository;         private void InitGrid()         {             // advBandedGridView1是表格上的默認視圖,注意這里聲明的是:BandedGridView             BandedGridView view = advBandedGridView1 as BandedGridView;             view.BeginUpdate(); //開始視圖的編輯,防止觸發其他事件             view.BeginDataUpdate(); //開始數據的編輯             view.Bands.Clear();

 

            view.OptionsView.ShowColumnHeaders = false;                         //因為有Band列了,所以把ColumnHeader隱藏             //添加列標題       //添加列標題
            GridBand bandID = view.Bands.AddBand("ID");             bandID.Visible =false; //隱藏ID列
            GridBand bandName = view.Bands.AddBand("姓名");             GridBand bandSex = view.Bands.AddBand("性別");             GridBand bandBirth = view.Bands.AddBand("出生日期");             GridBand bandScore = view.Bands.AddBand("分數");             GridBand bandMath = bandScore.Children.AddBand("數學");             GridBand bandChinese = bandScore.Children.AddBand("語文");             GridBand bandEnglish = bandScore.Children.AddBand("英語");             GridBand bandSubTotal = bandScore.Children.AddBand("小計");             GridBand bandRemark = view.Bands.AddBand("備注");

 

            bandFile.AppearanceHeader.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;//這是合並表頭居中顯示             view.EndDataUpdate();//結束數據的編輯             view.EndUpdate();   //結束視圖的編輯         }

具體可看

dev gridcontrol 合並表頭

 

23.   //動態添加列             DevExpress.XtraGrid.Columns.GridColumn Col1 = new DevExpress.XtraGrid.Columns.GridColumn();             Col1.FieldName = "name";             Col1.Caption = "名字";             Col1.Visible = false;             Col1.VisibleIndex = gvCountry.Columns.Count;             gvCountry.Columns.Add(Col1);

 

24。設置自動增加的行號

  private void gridview_CustomDrawRowIndicator(object sender,                            DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)     {

e.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Far;             if (e.Info.IsRowIndicator)             {                 if (e.RowHandle >= 0)                 {                     e.Info.DisplayText = (e.RowHandle + 1).ToString();                 }                 else if (e.RowHandle < 0 && e.RowHandle > -1000)                 {                     e.Info.Appearance.BackColor = System.Drawing.Color.AntiqueWhite;                     e.Info.DisplayText = "G" + e.RowHandle.ToString();                 }             }

25.特效:gridcontrol中有5種view 型式,普通的是gridview,然后分別為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;         }

 

26.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");   }

  }

 

27.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;

 

 

 

28.列表過濾條件多選

列名.OptionsFilter.FilterPopupMode= DevExpress.XtraGrid.Columns.FilterPopupMode.CheckedList

 

29.隔行換色的方法

 

 

 

 

 

 

 

this.gridView1.Appearance.OddRow.BackColor = Color.White;  // 設置奇數行顏色 // 默認也是白色 可以省略 this.gridView1.OptionsView.EnableAppearanceOddRow = true;   // 使能 // 和和上面綁定 同時使用有效 this.gridView1.Appearance.EvenRow.BackColor = Color.WhiteSmoke; // 設置偶數行顏色 this.gridView1.OptionsView.EnableAppearanceEvenRow = true;   // 使能 // 和和上面綁定 同時使用有效
