ASPxGridView 用法

一、ASPxGridView属性：概述设置（Settings）

1.1、Settings 
<Settings 
GridLines="Vertical"            : 网格样式 Vertical, Both, None
ShowGroupPanel="True"           : 分组面板
ShowFooter="True"               : 脚注面板
ShowFilterRow="True"            : 过滤器行
ShowHeaderFilterButton="true"   : 表头过滤按钮
ShowFilterBar                     :允许显示过滤工具条
ShowGroupFooter="VisibleAlways" : 分组脚注面板 Hidden | VisibleIfExpand | VisibleAlways
ShowPreview="true"              : 预览面板
ShowVerticalScrollBar="True"    : 垂直滚动条
VerticalScrollableHeight="250"  : 垂直滚动条
/>
1.2、行为设置(SettingsBehavior)
<SettingsBehavior 
AllowDragDrop="False"           : 允许托拽
ColumnResizeMode="Control"      : 列宽度调整模式
AllowFocusedRow="True"          : 鼠标点击选择行
AllowSort                        :允许排序
AllowGroup                      :允许分组
autoExpandAllGroups            :自动展开所有组
ConfirmDelete                  :允许提交删除
AllowMultiSelection            :允许选择多行
/>
1.3、分页(SettingsPager)
<SettingsPager 
PageSize="30"                   : 分页大小
Mode="ShowAllRecords"           : 展示模式
SEOFriendly="Enabled"           : Search engine friendly
Position="TopAndBottom"         : 分页控件位置
>
<Summary AllPagesText="页: {0} / {1} ({2}行)" />
</SettingsPager>
1.4、文本设置(SettingsText)
<SettingsText
Title="标题"
EmptyDataRow="无数据" 
PopupEditFormCaption="编辑" 
ConfirmDelete="确定删除？" 
/>
1.5、Loading 面板设置(SettingsLoadingPanel)
<SettingsLoadingPanel Mode="ShowOnStatusBar" />
1.6、编辑视图设置(SettingsEditing)
<SettingsEditing 
PopupEditFormWidth = "600px" 
NewItemRowPosition = "Bottom"
Mode = "PopupEditForm"
/>
1.7、编辑模式 SettingsEditing.Mode
EditForm               : 当前行转化为表单,嵌入在行中
EditFormAndDisplayRow  : 同EditForm,但保留当前行
Inline                 : 在当前行现场编辑
PopupEditForm          : 弹出窗口编辑

1.8、行详细设置(SettingDetail)
<SettingDetail
AllowOnlyOneMasterRowExpanded  :允许只展开一列详细信息
ShowDetailRow                  :允许显示详细列表
IsDetailGrid                  :允许显示分组
> 

1.9 动态选中某一行：
AspxgridView1.Selection.SetSelection(i.true)
遍历所有行：
声明变量：DataRowView dv
For(int i=0;i< AspxgridView1.VisbleRowCount;i++)
{
　　选中行提取数据：
　　if(AspxgridView1.Selection.IsRowSelected(i))
　　{
　　　　行数据集  
　　　　dv=（DataRowView）AspxgridView1.GetRow(i);
　　}
}

二、ASPxGridView样式 & 格式

集中式样式
    <Styles>
        <Header HorizontalAlign="Center" />      : 标题居中对齐
        <AlternatingRow Enabled="true"/>         : 交错行效果
        <CommandColumn Paddings-Padding="1" />   : 
    </Styles>
列样式
    <dxwgv:GridViewDataTextColumn FieldName="Total" UnboundType="Decimal">
        <FooterCellStyle ForeColor="Brown"/>
    </dxwgv:GridViewDataTextColumn>
数字日期格式
    金额
        <dxwgv:GridViewDataTextColumn FieldName="UnitPrice" >
            <PropertiesTextEdit DisplayFormatString="c" />
        </dxwgv:GridViewDataTextColumn>
    时间
        <dxwgv:GridViewDataDateColumn Caption="Time" FieldName="Time">
            <PropertiesDateEdit DisplayFormatString="HH:mm:ss" />
            <CellStyle HorizontalAlign="Right" />
        </dxwgv:GridViewDataDateColumn>
图像
    <Images ImageFolder="~/App_Themes/Glass/{0}/">
        <CollapsedButton Height="12px" Width="11px" />
        <DetailCollapsedButton Height="9px" Width="9px" />
        <PopupEditFormWindowClose Height="17px" Width="17px" />
    </Images>

三、ASPxGridView分组 & 汇总 & 排序

间隔分组：将时间日期字段按个性分组，如年、月、日、周、季度、上周、下周.....
    <dxwgv:GridViewDataDateColumn FieldName="OrderDate" VisibleIndex="3" GroupIndex="0">
        <Settings  GroupInterval="DateYear"/>
    </dxwgv:GridViewDataDateColumn>

汇总
    <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>        
分组汇总
    <GroupSummary>
        <dxwgv:ASPxSummaryItem FieldName="Country" SummaryType="Count" />
        <dxwgv:ASPxSummaryItem FieldName="Quantity" SummaryType="Sum" />
        <dxwgv:ASPxSummaryItem FieldName="Total" SummaryType="Sum"  DisplayFormat="{0:c}"/>
    </GroupSummary>

            }
        }
    }
    注：模板列中的事件如何写？手工写事件，如btn.OnClick += ...;
    注：视图模板请参考文档《ASPxGridView.Templates》
ASPxGridView 事件
RowCreated（创建行数据时触发，类似 GridView 的 DataItemCreate 事件）
    protected void grid_HtmlRowCreated(object sender, DevExpress.Web.ASPxGridView.ASPxGridViewTableRowEventArgs e) 
    {
        if(e.RowType != DevExpress.Web.ASPxGridView.GridViewRowType.Data) return;
        // 设置模板列lable控件值
        Label label = grid.FindRowCellTemplateControl(e.VisibleIndex, null, "changePercent") as Label;
        decimal change = (decimal)grid.GetRowValues(e.VisibleIndex, "Change");
        label.Text = string.Format("{0:p}", change);
        // 设置模板列image控件的图像
        System.Web.UI.WebControls.Image img = (System.Web.UI.WebControls.Image)grid.FindRowCellTemplateControl(e.VisibleIndex, null, "changeImage");

        hasError = hasError || e.GetValue("LastName").ToString().Length <= 1;
        hasError = hasError || !e.GetValue("Email").ToString().Contains("@");
        hasError = hasError || (int)e.GetValue("Age") < 18;
        DateTime arrival = (DateTime)e.GetValue("ArrivalDate");
        hasError = hasError || DateTime.Today.Year != arrival.Year || DateTime.Today.Month != arrival.Month;
        if(hasError) {

             e.DisplayText = GetSizeDisplayText(e.Value);
     }
SummaryDisplayText（合计行文本展示）
     protected void grid_SummaryDisplayText(object sender, DevExpress.Web.ASPxGridView.ASPxGridViewSummaryDisplayTextEventArgs e) {
         if(e.Item.FieldName == "Size") {
             e.Text = GetSizeDisplayText(e.Value);
         }
     }
HeaderFilterFillItems（自定义过滤器处理逻辑）
    protected void grid_HeaderFilterFillItems(object sender, ASPxGridViewHeaderFilterEventArgs e) 
    {
        if(object.Equals(e.Column, grid.Columns["Total"])) {

            return;
        }
    }

    {
        int layoutIndex = -1;
        if(int.TryParse(e.Parameters, out layoutIndex))
            ApplyLayout(layoutIndex); // 更换布局
    }

            e.Cancel = true;
            FunctionDataBind();//更新数据
        }
       行添加事件RowInserting

                e.Cancel = true;
                FunctionDataBind();//更新数据
        }

   行删除事件RowDeleting
        protected void gvFunction_RowDeleting(object sender, DevExpress.Web.Data.ASPxDataDeletingEventArgs e)
        {
            functionModel.FunctionId = e.Keys[0].ToString();// ID

            e.Cancel = true;
            FunctionDataBind();//更新数据
        }
       初始化回调事件 Callback

            SelectUser();// 查找组里面的所有用户
            DataCheck();
        }
获取行展开改变事件 DetailRowExpandedChanged
        protected void gvGroup_DetailRowExpandedChanged(object sender, ASPxGridViewDetailRowEventArgs e)
        {
            SYSolution_WebUI.ServiceReference.GroupInfo groupInfoModel = (SYSolution_WebUI.ServiceReference.GroupInfo)((ASPxGridView)sender).GetRow(e.VisibleIndex);// 获取选中行实体
　　　　　　　ASPxGridView gv = (ASPxGridView)gvGroup.FindDetailRowTemplateControl(e.VisibleIndex, "gvGroupName");   // 获取模板内aspxgridView ID名称
            SYSolution_WebUI.ServiceReference.GroupInfo[] model = client.GroupSelUserList("GroupId='" + groupInfoModel.GroupId + "'");// 通过组ID值获取实体对象
            if (model[0].UserInfoList != null && gv != null)// 当用用户列表值与子aspxgridView不为空
            {

            }
        }
排序事件中重新绑定数据 BeforeColumnSortingGrouping
       protected void gvGroup_BeforeColumnSortingGrouping(object sender, ASPxGridViewBeforeColumnGroupingSortingEventArgs e)
        {
            gvGroup.DetailRows.CollapseAllRows();// 关闭所有DetailoRow
            gvGroup.DetailRows.ExpandRow(3);
        }
重绑定数据使用时先选中行，再查看 FocusedRowChanged
Protected void aspxGridView_FocusedRowChanged(object sender,EventArgs e){}

行列绑定数据事件CustomUnboundColumnData
Protected void aspxGridView_CustomUnboundColumnData(object sender,EventArgs e){}

.隐藏编辑列，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;
        }
    }
