c# - 如何从 SelectionModel 外部的 Ext.Net.GridPanel 中的当前选定行获取值？

Question

我的 .aspx 文件中有以下代码

<ext:GridPanel
            runat="server"
            ID="GridPanel1"
            Height="450"
            Title="EmployeeList"
            Width = "850"
            Header = "false"
            StyleSpec = "margin: 25px;"
            StripeRows="true"
            TrackMouseOver="true"
            Border="true" ClicksToEdit="2">
            <Store>
                <ext:Store ID="Store1" runat="server" DataSourceID="LinqDataSource1">
                    <Reader>
                        <ext:JsonReader IDProperty="id" >
                            <Fields>
                                <ext:RecordField Name="id" />
                                <ext:RecordField Name="shortcode" />
                                <ext:RecordField Name="lastname" />
                                <ext:RecordField Name="firstname" />
                                <ext:RecordField Name="roomnumber" />
                                <ext:RecordField Name="landline" />
                                <ext:RecordField Name="mobile" />
                                <ext:RecordField Name="mail" />
                                <ext:RecordField Name="position" />
                                <ext:RecordField Name="department" />
                            </Fields>
                        </ext:JsonReader>
                    </Reader>
                </ext:Store>
            </Store>
            <ColumnModel ID="ColumnModel1" runat="server" >
                <Columns>
                    <ext:Column DataIndex="id" Header="Index" Width="50"/>
                    <ext:Column DataIndex="shortcode" Header="Kuerzel" Align="Center" />
                    <ext:Column DataIndex="lastname" Header="Nachname"   />
                    <ext:Column DataIndex="firstname" Header="Vorname"  />
                    <ext:Column DataIndex="roomnumber" Header="Raumnummer" Align="Center" Width="50"/>
                    <ext:Column DataIndex="landline" Header="Durchwahl intern" Align="Center" Width="50"/>
                    <ext:Column DataIndex="mobile" Header="Durchwahl handy"  Align="Center" Width="50"/>
                    <ext:Column DataIndex="mail" Header="Mail"  />
                    <ext:Column DataIndex="position" Header="Funktion"  />
                    <ext:Column DataIndex="department" Header="Abteilung"  />
                </Columns>
            </ColumnModel>  
            <SelectionModel>
                <ext:RowSelectionModel ID="RowSelectionModel1" SingleSelect="true">

<%--                   <Listeners> 
                        <RowSelect Handler="#{EditPanel}.getForm().loadRecord(record);" /> 
                    </Listeners>--%>

                    <DirectEvents>
                        <RowSelect OnEvent="SaveCurrentSelection">
                            <ExtraParams>
                                <ext:Parameter Name="usID" Value="this.getSelected().id" Mode="Raw" />
                            </ExtraParams>
                        </RowSelect>
                    </DirectEvents>
                </ext:RowSelectionModel> 
            </SelectionModel>   
        <KeyMap>
            <ext:KeyBinding Ctrl="true">
                <Keys>
                    <ext:Key Code="Y" />
                </Keys>
                <Listeners>
                    <Event Handler="#{DirectMethods}.ShowSearchWindow();" />
                </Listeners>
            </ext:KeyBinding>
        </KeyMap>
        <DirectEvents>
            <RowDblClick OnEvent="SwitchToUserDetail">
                <ExtraParams>
                    <ext:Parameter Name="id" Value="this.selModel.getSelected().id" Mode="Raw"></ext:Parameter>
                </ExtraParams>
            </RowDblClick>
        </DirectEvents>     

        </ext:GridPanel>

现在我需要获取当前选定行的 id 字段，就像我在 RowSelect 监听器中获取它一样

<ext:Parameter Name="usID" Value="this.getSelected().id" Mode="Raw" />

但这次不在 SelectionModel 中。我需要在这里得到它:

<DirectEvents>
  <RowDblClick OnEvent="SwitchToUserDetail">
    <ExtraParams>
        <ext:Parameter Name="id" Value="this.selModel.getSelected().id" Mode="Raw"></ext:Parameter>
    </ExtraParams>
  </RowDblClick>
 </DirectEvents>

在 SelectionModel 外部但在 GridPanel 内部。

我认为方法是在这里获取它:

Value = "this.selModel.getSelected().id"

我需要在此处获取它，因为我不想在 CodeBehind 中执行此操作，而且 Listener 和 DirectEvent 在我的 SelectionModel 中无法协同工作

不胜感激

您可以像这样访问记录字段

this.selModel.getSelected().data.shortcode
