Telerik Radgrid 控制详细信息屏幕在单击主记录时不刷新

我的aspx页面上有两个radgrid：Log和LogDetails。

当我单击日志网格上的一行时，我希望 LogDetails 使用 LogGrid 的日志 ID 刷新。但细节网格并不令人耳目一新。

请帮助我。这是我的代码。谢谢

     protected void OnLogGridNeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
    {
        var logs = LogManager.FindLog();
        var sortedlogs = from l in logs
                         orderby l.LogId descending
                         select l;
        grdLogGrid.DataSource = sortedlogs;
    }
    protected void OnLogDetailGridNeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
    {
        int logid = 0; 
        if (grdLogGrid.SelectedValue != null)
            logid = Convert.ToInt32(grdLogGrid.SelectedValue.ToString());

        var logDetails = LogManager.FindLogDetail();
        var logDetail = from ld in logDetails
                        where ld.LogId == logid
                        select ld;
        grdLogDetailGrid.DataSource = logDetail;
    }
    protected void OnLogGridItemCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
    {
        grdLogDetailGrid.Rebind();
    }
