一、ASPxGridView屬性：概述設置（Settings）
1.1、Settings
<Settings GridLines="Vertical" : 網格樣式 Vertical, Both, None ShowGroupPanel="True" : 分組面板 ShowFooter="True" : 腳注面板 ShowFilterRow="True" : 過濾器行 ShowHeaderFilterButton="true" : 表頭過濾按鈕 ShowFilterBar :允許顯示過濾工具條 ShowGroupFooter="VisibleAlways" : 分組腳注面板 Hidden | VisibleIfExpand | VisibleAlways ShowPreview="true" : 預覽面板 ShowVerticalScrollBar="True" : 垂直滾動條 VerticalScrollableHeight="250" : 垂直滾動條 /> 1.2、行為設置(SettingsBehavior) <SettingsBehavior AllowDragDrop="False" : 允許托拽 ColumnResizeMode="Control" : 列寬度調整模式 AllowFocusedRow="True" : 鼠標點擊選擇行 AllowSort :允許排序 AllowGroup :允許分組 autoExpandAllGroups :自動展開所有組 ConfirmDelete :允許提交刪除 AllowMultiSelection :允許選擇多行 /> 1.3、分頁(SettingsPager) <SettingsPager PageSize="30" : 分頁大小 Mode="ShowAllRecords" : 展示模式 SEOFriendly="Enabled" : Search engine friendly Position="TopAndBottom" : 分頁控件位置 > <Summary AllPagesText="頁: {0} / {1} ({2}行)" /> </SettingsPager> 1.4、文本設置(SettingsText) <SettingsText Title="標題" EmptyDataRow="無數據" PopupEditFormCaption="編輯" ConfirmDelete="確定刪除？" /> 1.5、Loading 面板設置(SettingsLoadingPanel) <SettingsLoadingPanel Mode="ShowOnStatusBar" /> 1.6、編輯視圖設置(SettingsEditing) <SettingsEditing PopupEditFormWidth = "600px" NewItemRowPosition = "Bottom" Mode = "PopupEditForm" /> 1.7、編輯模式 SettingsEditing.Mode EditForm : 當前行轉化為表單,嵌入在行中 EditFormAndDisplayRow : 同EditForm,但保留當前行 Inline : 在當前行現場編輯 PopupEditForm : 彈出窗口編輯 1.8、行詳細設置(SettingDetail) <SettingDetail AllowOnlyOneMasterRowExpanded :允許只展開一列詳細信息 ShowDetailRow :允許顯示詳細列表 IsDetailGrid :允許顯示分組 >
1.9 動態選中某一行： AspxgridView1.Selection.SetSelection(i.true) 遍歷所有行： 聲明變量：DataRowView dv For(int i=0;i< AspxgridView1.VisbleRowCount;i++) { 選中行提取數據：
if(AspxgridView1.Selection.IsRowSelected(i)) { 行數據集
dv=（DataRowView）AspxgridView1.GetRow(i); } }
二、ASPxGridView樣式 & 格式
集中式樣式 <Styles> <Header HorizontalAlign="Center" /> : 標題居中對齊 <AlternatingRow Enabled="true"/> : 交錯行效果 <CommandColumn Paddings-Padding="1" /> : </Styles> 列樣式 <dxwgv:GridViewDataTextColumn FieldName="Total" UnboundType="Decimal"> <FooterCellStyle ForeColor="Brown"/> </dxwgv:GridViewDataTextColumn> 數字日期格式 金額 <dxwgv:GridViewDataTextColumn FieldName="UnitPrice" > <PropertiesTextEdit DisplayFormatString="c" /> </dxwgv:GridViewDataTextColumn> 時間 <dxwgv:GridViewDataDateColumn Caption="Time" FieldName="Time"> <PropertiesDateEdit DisplayFormatString="HH:mm:ss" /> <CellStyle HorizontalAlign="Right" /> </dxwgv:GridViewDataDateColumn> 圖像 <Images ImageFolder="~/App_Themes/Glass/{0}/"> <CollapsedButton Height="12px" Width="11px" /> <DetailCollapsedButton Height="9px" Width="9px" /> <PopupEditFormWindowClose Height="17px" Width="17px" /> </Images>
三、ASPxGridView分組 & 匯總 & 排序
間隔分組：將時間日期字段按個性分組，如年、月、日、周、季度、上周、下周..... <dxwgv:GridViewDataDateColumn FieldName="OrderDate" VisibleIndex="3" GroupIndex="0"> <Settings GroupInterval="DateYear"/> </dxwgv:GridViewDataDateColumn> 匯總 <TotalSummary> <dxwgv:ASPxSummaryItem FieldName="CompanyName" SummaryType="Count"/> <dxwgv:ASPxSummaryItem FieldName="Total" SummaryType="Sum" DisplayFormat="c"/> <dxwgv:ASPxSummaryItem FieldName="Quantity" SummaryType="Min" /> <dxwgv:ASPxSummaryItem FieldName="Quantity" SummaryType="Average" /> <dxwgv:ASPxSummaryItem FieldName="Quantity" SummaryType="Max" /> </TotalSummary> 分組匯總 <GroupSummary> <dxwgv:ASPxSummaryItem FieldName="Country" SummaryType="Count" /> <dxwgv:ASPxSummaryItem FieldName="Quantity" SummaryType="Sum" /> <dxwgv:ASPxSummaryItem FieldName="Total" SummaryType="Sum" DisplayFormat="{0:c}"/> </GroupSummary>
ASPxGridView 列： --------------------------------------------------------- 基本列(GridViewDataColumn) <dxwgv:GridViewDataColumn FieldName="Country" VisibleIndex="5" /> 其他列 <dx:GridViewDataTextColumn /> : 文本列 <dx:GridViewDataMemoColumn /> : 長文本列 <dx:GridViewDataImageColumn /> : 圖像列 <dx:GridViewDataBinaryImageColumn /> : 二進制圖像列 <dx:GridViewDataDateColumn /> : 日期列 <dx:GridViewDataTimeEditColumn /> : 時間列 <dx:GridViewDataComboBoxColumn /> : 組合框列 <dx:GridViewDataDropDownEditColumn /> : 下拉框編輯列？ <dx:GridViewCommandColumn /> : 命令按鈕列 <dx:GridViewDataButtonEditColumn /> : 編輯按鈕列？ <dx:GridViewDataCheckColumn /> : 復選框列 <dx:GridViewDataColorEditColumn /> : 色彩列 <dx:GridViewDataHyperLinkColumn /> : 超鏈接列 <dx:GridViewDataProgressBarColumn /> : 進度條列 <dx:GridViewDataSpinEditColumn /> : SpinEdit列 長文本列（GridViewDataMemoColumn） 編輯時展現為多行文本框 <dx:GridViewDataMemoColumn FieldName="Remarks" Caption="備注" EditCellStyle-BackColor="Yellow" // 行的背景顏色 PropertiesMemoEdit-Rows="4" // 添加或是修改時跨行 EditFormSettings-ColumnSpan="2" //添加或是修改時跨列 /> 超鏈接列(GridViewDataHyperLinkColumn) <dx:GridViewDataHyperLinkColumn FieldName="ArticleId" Caption="查看" > <PropertiesHyperLinkEdit Text="查看" TextFormatString="" /> </dx:GridViewDataHyperLinkColumn> 組合框列（GridViewDataComboBoxColumn） <dx:ASPxGridView OnCellEditorInitialize="grid_CellEditorInitialize"> <dxwgv:GridViewDataComboBoxColumn FieldName="City" VisibleIndex="2"> <PropertiesComboBox EnableSynchronization="False" EnableIncrementalFiltering="True" DropDownStyle="DropDown" /> </dxwgv:GridViewDataComboBoxColumn> </dx:ASPxGridView> protected void grid_CellEditorInitialize(object sender, ASPxGridViewEditorEventArgs e) { // 用下拉框展示國家下的所有城市綁定數據源 if(grid.IsEditing && e.Column.FieldName != "City" && !grid.IsNewRowEditing) { ASPxComboBox combo = e.Editor as ASPxComboBox;
