ASPxGridView 用法整理

ASPxGridView屬性：概述設置（Settings）
    <Settings 
        GridLines="Vertical"            : 網格樣式 Vertical, Both, None
        ShowGroupPanel="True"           : 分組面板
        ShowFooter="True"               : 腳註面板
        ShowFilterRow="True"            : 過濾器行
        ShowHeaderFilterButton="true"   : 表頭過濾按鈕

ShowFilterBar                     :容許顯示過濾工具條
        ShowGroupFooter="VisibleAlways" : 分組腳註面板 Hidden | VisibleIfExpand | VisibleAlways
        ShowPreview="true"              : 預覽面板
        ShowVerticalScrollBar="True"    : 垂直滾動條
        VerticalScrollableHeight="250"  : 垂直滾動條
        />

行爲設置（SettingsBehavior）
    <SettingsBehavior 
        AllowDragDrop="False"           : 容許託拽
        ColumnResizeMode="Control"      : 列寬度調整模式
        AllowFocusedRow="True"          : 鼠標點擊選擇行

AllowSort                        :容許排序

AllowGroup                      :容許分組

autoExpandAllGroups            ：自動展開全部組

ConfirmDelete                  ：容許提交刪除

AllowMultiSelection            ：容許選擇多行

/>

分頁（SettingsPager）
    <SettingsPager 
        PageSize="30"                   : 分頁大小
        Mode="ShowAllRecords"           : 展現模式
        SEOFriendly="Enabled"           : Search engine friendly
        Position="TopAndBottom"         : 分頁控件位置
        >
        <Summary AllPagesText="頁: {0} / {1} ({2}行)" />
    </SettingsPager>

文本設置（SettingsText）
       <SettingsText
        Title="標題"
        EmptyDataRow="無數據" 
        PopupEditFormCaption="編輯" 
        ConfirmDelete="肯定刪除？" 
        />

Loading 面板設置（SettingsLoadingPanel）
    <SettingsLoadingPanel Mode="ShowOnStatusBar" />

編輯視圖設置（SettingsEditing）
    <SettingsEditing 
        PopupEditFormWidth = "600px" 
        NewItemRowPosition = "Bottom"
        Mode = "PopupEditForm"
        />

編輯模式 SettingsEditing.Mode
            EditForm               : 當前行轉化爲表單，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

行詳細設置（SettingDetail）

<SettingDetail

AllowOnlyOneMasterRowExpanded  :容許只展開一列詳細信息

ShowDetailRow                  ：容許顯示詳細列表

 IsDetailGrid                  ：容許顯示分組

> 

動態選中某一行：

AspxgridView1.Selection.SetSelection(i.true)

遍歷全部行：

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);

}

}

        }

   行刪除事件RowDeleting

        protected void gvFunction_RowDeleting(object sender, DevExpress.Web.Data.ASPxDataDeletingEventArgs e)

        {

            functionModel.FunctionId = e.Keys[0].ToString();// ID

            client.FunctionInfoDelete(functionModel);

            gvFunction.CancelEdit();//結束編輯狀態

            e.Cancel = true;

            FunctionDataBind();//更新數據

        }

 

       初始化回調事件 Callback

        protected void callbackPanel_Callback(object sender, DevExpress.Web.ASPxClasses.CallbackEventArgsBase e)

        {

            strGroupID = e.Parameter.ToString();

            DataBindInfo();// 初始化頁面信息

            SelectUser();// 查找組裏面的全部用戶

            DataCheck();

 

        }

 

獲取行展開改變事件 DetailRowExpandedChanged

        protected void gvGroup_DetailRowExpandedChanged(object sender, ASPxGridViewDetailRowEventArgs e)

        {

 

            SYSolution_WebUI.ServiceReference.GroupInfo groupInfoModel = (SYSolution_WebUI.ServiceReference.GroupInfo)((ASPxGridView)sender).GetRow(e.VisibleIndex);// 獲取選中行實體

            ASPxGridView gv = (ASPxGridView)gvGroup.FindDetailRowTemplateControl(e.VisibleIndex, "gvGroupName");   // 獲取模板內aspxgridView ID名稱

            SYSolution_WebUI.ServiceReference.GroupInfo[] model = client.GroupSelUserList("GroupId='" + groupInfoModel.GroupId + "'");// 經過組ID值獲取實體對象

            if (model[0].UserInfoList != null && gv != null)// 當用用戶列表值與子aspxgridView不爲空

            {

                gv.DataSource = model[0].UserInfoList;      // 子aspxgridView綁定數據源

                gv.DataBind();

            }

            if (model[0].UserInfoList[0].Name == "")       // 若是子aspxgridView中的用戶列表爲空時不顯示 不展開

            {

                gvGroup.SettingsDetail.AllowOnlyOneMasterRowExpanded = false;

            }

        }

 

排序事件中從新綁定數據 BeforeColumnSortingGrouping

       protected void gvGroup_BeforeColumnSortingGrouping(object sender, ASPxGridViewBeforeColumnGroupingSortingEventArgs e)

        {

            gvGroup.DetailRows.CollapseAllRows();// 關閉全部DetailoRow

 

            gvGroup.DetailRows.ExpandRow(3);

        }

重綁定數據使用時先選中行，再查看 FocusedRowChanged

Protected void aspxGridView_FocusedRowChanged(object sender,EventArgs e){}

 

行列綁定數據事件CustomUnboundColumnData

Protected void aspxGridView_CustomUnboundColumnData(object sender,EventArgs e){}

 

.隱藏編輯列，在DataBound事件中protected void ASPxGridView1_DataBound(object sender, EventArgs e)    {        if(ASPxGridView1.VisibleRowCount>0)        {            //ASPxGridView1.Columns[命令列索引]            (ASPxGridView1.Columns[4] as GridViewCommandColumn).NewButton.Visible = false;        }    }
