前台

<DirectEvents>

            <Command OnEvent="Command">

                <ExtraParams>

                    <extnet:Parameter Name="Id" Value="record.data.Id" Mode="Value" />

后台

protected void Command(object sender, DirectEventArgs e)

    {

        var command = e.ExtraParams["command"].ToString();

        var Id = ConvertHelper.ToInt(e.ExtraParams["Id"].ToString());

        X.Msg.Alert("Command", e.ExtraParams["id"] + " : " + e.ExtraParams["command"]).Show();
