寫在前面，Dev控件已經(jīng)很久了，功能也很強(qiáng)大，截止到現(xiàn)在我編寫文檔出來的Dev的版本已經(jīng)到了14.1了，看了Demo真的很強(qiáng)大，效果也很好，結(jié)合自己這一個(gè)月開發(fā)，分享一下自己研究過后的經(jīng)驗(yàn)，不讓大家走更多的彎路

• DevExpress安裝順序
• GridControl基本樣式設(shè)置
• GridControl常用事件和描述
• GridControl右鍵菜單
• GridControl全選和反選
• GridControl添加小計(jì)功能
• GridControl固定表頭

  1.安裝從未如此簡(jiǎn)單

  Dev的安裝文件已經(jīng)放大百度云中方便大家下載：DevExpress 12.2.7，下載后按照?qǐng)D片數(shù)字順序依次安裝，這就是Dev 12.2.7，你值得擁有。

  if (bandedGridView1.GetFocusedDataRow() == null) return;//運(yùn)單編號(hào)var columnValue= bandedGridView1.GetFocusedRowCellValue("綁定列字段名稱").ToString();

  ?

  ?

  ?

  注意事項(xiàng)：使用VS2012和2010搭配DevExpress 12.2.7這個(gè)版本一起開發(fā)是最好的，工具箱暫時(shí)無法導(dǎo)入VS2013

  2.基本樣式設(shè)置，你會(huì)嗎？

  面對(duì)第一次使用GridControl，搞不懂GridControl下面為什么有一堆的GridView呢？后來想想，原來GridControl是一個(gè)大容器，下面有很多視圖，那么就是操作視圖，下面是我的一些常用樣式設(shè)置。

??

bandedGridView1.IndicatorWidth = 40; //自增列寬度bandedGridView1.OptionsView.ColumnAutoWidth = false; //自動(dòng)調(diào)整列寬，使所有列的寬度和視圖的寬度匹配bandedGridView1.OptionsCustomization.AllowSort = false;//禁止用戶對(duì)數(shù)據(jù)進(jìn)行排序操作bandedGridView1.OptionsCustomization.AllowColumnResizing = false; //禁止各列頭改變列寬bandedGridView1.VertScrollVisibility = ScrollVisibility.Auto; //顯示垂直滾動(dòng)條bandedGridView1.HorzScrollVisibility = ScrollVisibility.Auto; //顯示水平滾動(dòng)條bandedGridView1.OptionsMenu.EnableColumnMenu = false; //禁止列頭上的菜單bandedGridView1.OptionsMenu.EnableFooterMenu = false; //禁止頁腳上的菜單bandedGridView1.OptionsMenu.EnableGroupPanelMenu = false; //禁止分組面板上的菜單bandedGridView1.OptionsNavigation.UseTabKey = false; //不使用TAB/SHIFT+TAB移動(dòng)焦點(diǎn)bandedGridView1.OptionsBehavior.Editable = false;//不允許編輯bandedGridView1.OptionsBehavior.ReadOnly = true;//只讀

　? 3.這些事件你會(huì)常用

? ? ?CustomDrawRowIndicator：DGV顯示自增行號(hào)

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

? ? ? ? ? ?RowCellStyle：GridView隔行變色

bandedGridView1.Appearance.OddRow.BackColor = Color.White; // 設(shè)置奇數(shù)行顏色 // 默認(rèn)也是白色 可以省略 bandedGridView1.OptionsView.EnableAppearanceOddRow = true; // 使能 // 和和上面綁定 同時(shí)使用有效 bandedGridView1.Appearance.EvenRow.BackColor = Color.FromArgb(255, 250, 205); // 設(shè)置偶數(shù)行顏色 bandedGridView1.OptionsView.EnableAppearanceEvenRow = true; // 使能 // 和和上面綁定 同時(shí)使用有效if (e.RowHandle == bandedGridView1.FocusedRowHandle){e.Appearance.Font = new Font("宋體", 9, FontStyle.Bold);} View Code

?　　　 FocusedRowChanged：選中行改變綁定行數(shù)據(jù)到對(duì)應(yīng)控件中?

if (bandedGridView1.GetFocusedDataRow() == null) return;//判斷當(dāng)前選中行是否為null//返回值var columnValue= bandedGridView1.GetFocusedRowCellValue("綁定列字段名稱").ToString();

　　 ? 4.添加右擊菜單一個(gè)很常用的功能

? ? ?

? ??添加ContextMenuStrip控件，然后自定義按鈕，可以找一些16*16的小圖標(biāo)點(diǎn)綴一下，很不錯(cuò)

? ? ? ?

這樣一個(gè)右鍵菜單就已經(jīng)綁定成功

? ? ??5.GridControl全選和反選

? ? ?這是一個(gè)比較難的問題，這里我結(jié)合網(wǎng)上尋找的資料總結(jié)了一個(gè)實(shí)體類貼上源代碼

?

下面是使用步驟

窗體加載事件添加一些代碼

private bool _mCheckStatus; //GridControl全選，作為全局變量，默認(rèn)falseprivate void FrmInputBill_Load(object sender, EventArgs e){bandedGridView1.OptionsBehavior.Editable = false;bandedGridView1.OptionsBehavior.ReadOnly = true;var col = new BandedGridColumn { FieldName = "Check", Visible = true, VisibleIndex = 0, ColumnEdit = new RepositoryItemCheckEdit() };col.OptionsColumn.AllowEdit = true; //CheckBox可以編輯改變gridBand1.Columns.Insert(0, col);bandedGridView1.Click += bandedGridView1_Click;bandedGridView1.CustomDrawColumnHeader += bandedGridView1_CustomDrawColumnHeader;bandedGridView1.DataSourceChanged += bandedGridView1_DataSourceChanged;//這里綁定數(shù)據(jù)源 }#region GridControl支持全選事件private void bandedGridView1_Click(object sender, EventArgs e){if (DevControlHelper.ClickGridCheckBox(this.bandedGridView1, "Check", _mCheckStatus)){_mCheckStatus = !_mCheckStatus;}}private void bandedGridView1_CustomDrawColumnHeader(object sender, ColumnHeaderCustomDrawEventArgs e){if (e.Column != null && e.Column.FieldName == "Check"){e.Info.InnerElements.Clear();e.Painter.DrawObject(e.Info);DevControlHelper.DrawCheckBox(e, _mCheckStatus);e.Handled = true;}}private void bandedGridView1_DataSourceChanged(object sender, EventArgs e){GridColumn column = this.bandedGridView1.Columns.ColumnByFieldName("Check");if (column != null){column.Width = 40;column.OptionsColumn.ShowCaption = false;column.ColumnEdit = new RepositoryItemCheckEdit();}}#endregion 全選和反選

?

6.添加小計(jì)功能
第一步

第二步
加載完數(shù)據(jù)之后綁定

bandedGridView1.Columns["綁定字段列名"].Summary.Add(DevExpress.Data.SummaryItemType.Count,?"BILL_CODE",?"總計(jì):{0}條");?//添加小計(jì)功能，在指定的列上添加一個(gè)統(tǒng)計(jì)對(duì)象 刪除動(dòng)作修改對(duì)應(yīng)的小計(jì)信息，代碼如下： bandedGridView1.Columns["綁定字段列名"].Summary[0].DisplayFormat?= string.Format("小計(jì){0}條",?bandedGridView1.RowCount); 7.固定表頭


記錄了一些GridControl的常用代碼，分享給大家，如果有興趣的可以到我的群里進(jìn)行提問，不僅包括GridControl，其他的控件我也研究了，運(yùn)用到項(xiàng)目中

將來的你一定會(huì)感激現(xiàn)在拼命的自己

總結(jié)
