EXT.NET复杂布局（一）——工作台

前面已经提到过EXT.NET了。EXT.NET是一组基于ExtJS库开发的开源的ASP.NET组件。

使用Ext.NET开发，比直接写JS更利于维护，也更方便开发。由于官方没有文档（只有DEMO），很多情况下只能看看DEMO并且结合Extjs的API来摸索了。因此，在开发一些相对复杂的布局的界面时，还是有一定难度的。接下来，笔者将一一讲述自己在开发过程中设计的一些相对复制的布局的界面，权且作为自我总结，也给新人接手时留点文档。如有不足之处，请回复。由于一直都很忙，不一定会回复。编写此文，也是断断续续的。

下面就从工作台开始吧，如以下界面：

当点击其他折叠面板时，如【可撤销事务】，该面板就会展开，并刷新数据:

那么具体是怎么实现的呢，下面来分析代码吧。

(一)首先，将EXT.NET控件添加到网页，并指定前缀。并添加ResourceManager控件。

具体代码如下：

1 2	`<%@ Register Assembly="Ext.Net"` `Namespace="Ext.Net"` `TagPrefix="ext"` `%>` `<ext:ResourceManager ID="ResourceManager1"` `runat="server"` `/>`

至于将EXT.NET控件添加到项目等等步骤，笔者就不介绍了。

ResourceManager控件是Extjs整个AJAX请求的核心。在添加任何Ext.NET控件前，都需要先添加ResourceManager控件。

（二）接下来，就需要编写一些JS了。

使用EXT.NET就不代表不需要写EXTJS,更不代表不需要了解Extjs。你会发现，在使用EXT.NET的过程中，也会对Extjs有一定的了解。下面先将JS贴上来：

1	`下面就一一说明这些JS函数：`

1	`<strong>ShowWin：打开一个新的带关闭按钮、最大化、最小化的模式窗口。listeners里面添加了beforedestroy事件，该事件在窗口关闭时触发。</strong>`

1	`<strong>“<%=Store1.ClientID %>.reload();”用于刷新“待处理事务”的数据。当服务器控件放在用户控件或者母版页里面时，注意使用服务器标记来获取客户端ID。</strong>`

1	`<strong>toExcuteOperations：封装在另外的JS文件里，用于处理每项事务，由于代码量多，就不贴出来了。</strong>`

1	`<strong>updateStore：更新数据。有的控件设置了<em>IDMode="Static"，</em>故可以直接使用控件的服务器ID来获取对象。</strong>`

1	`<strong>ExcuteCommand：执行命令。当为View时，打开相应的窗口。</strong>`

1	`<strong>getPageSize1：获取分页数。</strong>`

1	`<strong>checkboxBeforerowselect：在选择行首的复选框时的判断。即在某种情况下不可选。</strong>`

1	`<strong>setTitle：设置列显示的html。这里是当overtimeflag为1时，该行该列的数据加粗变红。引用地方如下：</strong>`

1 2	`<ext:Column ColumnID="TaskTitel"` `Header="任务名称"` `DataIndex="TaskTitel">` `<Renderer Fn="setTitle"` `Args="value, metadata, record, rowIndex, colIndex, store"` `/>`

1	`<strong>（三）然后，就需要编写页面代码了。先贴出代码：</strong>`

配置比较多，但是并不复杂。这种配置，比写js配置容易多了。而且更易于维护。都写这么多了，我也不过多讲解了。就简单说明下好了。

1）首先介绍下Viewport。ViewPort会随着浏览器显示区域的大小自动改变，它代表整个浏览器的显示区域。Viewport不需要指定renderTo，因为它直接渲染到页面的body区域，所以在一个页面中就只能有一个ViewPort实例。在自适应浏览器方面，使用Viewport很方便。接下来再看下面的配置：

<Listeners>
    <AfterLayout Handler="var vHeight= #{Viewport1}.getHeight();
                            #{pnlView}.setHeight(vHeight);
                            vHeight=vHeight-60;
                            GridPanel1.setHeight(vHeight);
                            GridPanel3.setHeight(vHeight);
                            GridPanel4.setHeight(vHeight);
                            GridPanel2.setHeight(vHeight);
                            GridPanel6.setHeight(vHeight);
                            GridPanel5.setHeight(vHeight);
                            " />
</Listeners>

在Viewport的AfterLayout 事件触发后，设置了所有的GridPanel的高度。

2）折叠面板：

1	`<ext:Panel` `runat="server" Layout="Accordion" ID="pnlView">`

3）获取数据。注意Store控件，这部分可以参考ExtjsAPI。

GroupField属性：分组的字段。

HttpProxy控件：HttpProxy用于请求远程数据，Url属性可以指定页面路径。

JsonReader控件：用于读取Json数据。注意属性TotalProperty和Root，分别是设置总记录数和根元素的，如果设置不正确，将读取不到数据。

BaseParams属性：用于设置请求的参数。在任何请求时都会发送，不同于AutoLoadParams属性。

Httphandler类部分代码如下：

/// 已办任务列表
/// </summary>
private void GetAlreadyDoTaskList()
{
    //设置JSON数据格式
    this.context.Response.ContentType = "text/json";
    TaskServices _ts = new TaskServices();
    var result = _ts.SelectTaskApproval();
    var pagingEmployees = new Paging<NewShopTaskList>(result, result.Count);
    var _json = JSON.Serialize(from e in pagingEmployees.Data
 
                               select new
                                          {
                                              e.TaskTitel,
                                              e.FSname,
                                              e.TaskBeginDate,
                                              e.TaskEndDate,
                                              e.TaskHours,
                                              e.UserName,
                                              e.BeginDate,
                                              e.ShopkeeperName,
                                              e.PhasesId,
                                              e.PhasesName,
                                              e.DealHours,
                                              e.DealDate,
                                              e.Remark,
                                              e.DealFAID,
                                              e.FAName,
                                              e.DealFSID,
                                              e.ShopName,
                                              e.PNID,
                                              e.PTID,
                                              e.overtimeflag
                                          });
    StoreResponseData sr = new StoreResponseData
                               {
                                   Total = pagingEmployees.TotalRecords,
                                   Data = _json
                               };
    sr.Return();
}

4）设置GridPanel的标题以及记录总数。

<Listeners>
    <Load Handler="#{GridPanel1}.setTitle('待处理事务<font style=color:green;font-weight:bolder;>（'+#{Store1}.getTotalCount()+'）</font>'); " />
</Listeners>

5）任务名在一定条件下变红。

<ext:Column ColumnID="TaskTitel" Header="任务名称" DataIndex="TaskTitel">
    <Renderer Fn="setTitle" Args="value, metadata, record, rowIndex, colIndex, store" />
</ext:Column>

setTitle函数上面介绍过，就不赘述了。

6）设置命令。

先设置命令列（ImageCommandColumn）：

<ext:ImageCommandColumn Header="操作" DataIndex="FileTypeName">
    <Commands>
        <ext:ImageCommand CommandName="View" Icon="TableEdit" />
    </Commands>
    <PrepareCommand Fn="prepareCommand" />
</ext:ImageCommandColumn>
<ext:ImageCommandColumn Header="审批历史">
    <Commands>
        <ext:ImageCommand CommandName="ExamineList" Icon="ApplicationViewList" Text="审批历史">
            <ToolTip Text="审批历史" />
        </ext:ImageCommand>
    </Commands>
</ext:ImageCommandColumn>

然后设置GridPanel的Listeners属性。

<Listeners>
    <Command Handler="ExcuteCommand(command,record);" />
    <GroupCommand Handler="if(command === 'SelectGroup'){ this.getSelectionModel().selectRecords(records, true); return;}else if(command=='UnSelectGroup'){this.getSelectionModel().clearSelections(); return;} else{toExcuteOperations(this.getSelectionModel().getSelections(),command);}" />
    <Expand Handler="#{Store1}.reload();" />
</Listeners>

7）满足一定条件的复选框才允许选择。

SelectionModel属性用于设置GridPanel的选择模型，有行选择、复选框选择等模型。这里的checkboxBeforerowselect函数已经介绍过，就不赘述了。

8）顶部工具条设置。这里的按钮是根据登陆角色结合任务来控制的。这部分在后台设置。具体如下：

100

101

102

103

104

105

106

107

108

109

110

111

112

113

114

115

116

117

118

119

120

        UserInfo userinfo = userServices.SelectUserbySharePointId();
        using (NBShopDataContext _db = new NBShopDataContext())
        {
            //获取操作Code列表
            var _FACodeLst = _db.SelectFacodeForTasklist(userinfo.UserId).ToList();
            if (_FACodeLst != null && _FACodeLst.Count > 0)
            {
                Toolbar1.Items.Clear();
                tbButtons.Items.Clear();
                foreach (var item in _FACodeLst)
                {
                    //转换成操作枚举
                    FACodeEnum _face = (FACodeEnum)System.Enum.Parse(typeof(FACodeEnum), item.facode);
                    switch (_face)
                    {
                        #region 取消

                            SetButton(Icon.PageBack, "退回", FACodeEnum.Reject, Toolbar1, "GridPanel1");
                            SetButton(Icon.PageBack, "退回", FACodeEnum.Reject, tbButtons, "GridPanel6");
                            break;
                        #endregion
                        #region 等待
                        //等待
                        case FACodeEnum.Wait:
                            SetButton(Icon.PackageGo, "等待", FACodeEnum.Wait, Toolbar1, "GridPanel1");
                            SetButton(Icon.PackageGo, "等待", FACodeEnum.Wait, tbButtons, "GridPanel6");
                            break;
                        #endregion
                        #region 通知
                        //通知

                            SetButton(Icon.NoteGo, "通知", FACodeEnum.Notice, Toolbar1, "GridPanel1");
                            SetButton(Icon.NoteGo, "通知", FACodeEnum.Notice, tbButtons, "GridPanel6");
                            break;
                        #endregion
                        //编辑
                        case FACodeEnum.Edit:
                            break;
                        #region 提交
                        //提交
                        case FACodeEnum.Submit:
                            SetButton(Icon.PageAdd, "提交", FACodeEnum.Submit, Toolbar1, "GridPanel1");
                            SetButton(Icon.PageAdd, "提交", FACodeEnum.Submit, tbButtons, "GridPanel6");
                            break;
                        #endregion
                        #region 同意
                        //同意
                        case FACodeEnum.Approve:
                            SetButton(Icon.Accept, "同意", FACodeEnum.Approve, Toolbar1, "GridPanel1");
                            SetButton(Icon.PageAdd, "同意", FACodeEnum.Approve, tbButtons, "GridPanel6");
                            break;
                        #endregion
                        default:
                            break;
                    }
                }
            }
        }
        //TODO:后期改为有数据则显示，无数据不显示
        if (userinfo.RoleCode == "Signingmember")
        {
            Store4.AutoLoad = true;
            GridPanel4.Hidden = false;
        }
 
    }

    if (toolbar.Items.Count > 0)

}

9）底部分页工具条。

<BottomBar>
    <ext:PagingToolbar ID="PagingToolbar1" runat="server" PageSize="50">
        <Items>
            <ext:Label ID="Label1" runat="server" Text="分页数:" />
            <ext:ToolbarSpacer ID="ToolbarSpacer1" runat="server" Width="10" />
            <ext:ComboBox ID="ComboBox1" runat="server" Width="80">
                <Items>
                    <ext:ListItem Text="10" />
                    <ext:ListItem Text="20" />
                    <ext:ListItem Text="30" />
                    <ext:ListItem Text="50" />
                </Items>
                <SelectedItem Value="50" />
                <Listeners>
                    <Select Handler="#{PagingToolbar1}.pageSize = parseInt(this.getValue()); #{PagingToolbar1}.doLoad();" />
                </Listeners>
            </ext:ComboBox>
        </Items>
    </ext:PagingToolbar>
</BottomBar>

1	`注意“#{PagingToolbar1}”。在EXT.NET里面，所有的Listeners事件都有Handler属性。在Handler属性里面写脚本，可以使用"#{ID}"来获取控件的客户端ID，`

1	`这里没有设置IDMode="Static"，所以当放置在用户控件或者母版页中的时候，会添加很多前缀，导致JS执行出错。`

1	`<strong>10）视图。这里用的是组视图（GroupingView）。如：</strong>`

<View>
    <ext:GroupingView ID="GroupingView1" HideGroupedColumn="true" StartCollapsed="true"
        runat="server" ForceFit="true" GroupTextTpl='{text} ({[values.rs.length]} {[values.rs.length > 1 ? "项" : "项"]})'
        GroupByText="按当前列分组" ShowGroupsText="是否分组" EnableRowBody="true" EnableGrouping="true">
    </ext:GroupingView>
</View>

这里的文字最好设置下，不然显示的是E文。
