Coolite 中GridView行按钮取行ID并调用服务器端代码

效果图：

关系代码：

 <Command Handler="if(command=='butSelectReocrd'){str=record.data.SessionId; #{AjaxMethods}.SelectRecord(str);}" />

全部html代码：

<ext:GridPanel ID="GridPanel1" Height="325" StoreID="Store1" runat="server" >      
    <ColumnModel ID="ColumnModelTitle" IDMode="Legacy" Height="30" runat="server">
        <Columns>
            <ext:ImageCommandColumn  Width="50" Align="Center" >
                    <Commands>
                        <ext:ImageCommand  CommandName="butSelectReocrd" Icon="Magnifier" >
                            <ToolTip Text="录音详情" />
                        </ext:ImageCommand >
                    </Commands>
            </ext:ImageCommandColumn > 
            <ext:Column ColumnID="SessionId" DataIndex="SessionId" Header="录音编号" Sortable="true" Width="120"/>
            <ext:Column ColumnID="RecordFile" DataIndex="RecordFile"  Header="录音文件" Sortable="false" Width="120"/>
            
                  </Columns>
    </ColumnModel>
    <Listeners>
        <Command Handler="if(command=='butSelectReocrd'){str=record.data.SessionId; #{AjaxMethods}.SelectRecord(str);}" />
    </Listeners> 
   <SelectionModel>
        <ext:RowSelectionModel SelectedRecordID="id" ID="RowSelectionModel1" runat="server">
            <CustomConfig>
                <ext:ConfigItem Name="checkOnly" Value="true" Mode="Raw" />
            </CustomConfig>
        </ext:RowSelectionModel>
    </SelectionModel>
    <LoadMask ShowMask="true" Msg="Load..."/>
   </ext:GridPanel>

C#代码：

[AjaxMethod]
public void SelectRecord(string strSessionId)//record.data.SessionId
{
        this.txtNetUserName1.Text = strSessionId;
        this.txtCustomerName.Text = "1111111";
        this.txtRecordFile.Text = "d:\\1111.wav"; 
        strPlayFile=@"d:\1111.wav";
}
