给Silverlight项目Ranet.UILibrary.OLAP添加客户端调试功能

关于Ranet.UILibrary.OLAP项目的简介请参考我的另一篇文章这里

不管什么原因，有时我们希望可以在Silverlight客户端进行调试，以查看发送到Server端的请求参数等信息，从而可以更好的定位问题；以下方法基于Ranet.UILibrary.OLAP项目，对其客户端添加一个调试窗口：

Add silverligth client debug feature in Ranet.UILibrary.OLAP:
1. change file \ranet-uilibrary-olap\UILibrary.Olap\UILibrary.Olap.MergeModule.Samples.Src\INSTALLDIR\Samples\UITest.Web\SilverliteApplication.htm :
 add ?debug=true in line 68(<param name="source" value="ClientBin/UITest.xap?debug=true")
2. change file \ranet-uilibrary-olap\UILibrary.Olap\UILibrary.Olap.MergeModule.Samples.Src\INSTALLDIR\Samples\UITest.Silverlight\evMdxDesigner.cs :

add InitDebug(); method

void InitDebug()
        {
            string src = App.Current.Host.Source.ToString();
            int idx = src.IndexOf("?");
            if (idx>-1)
            {
                string[] paramLst = src.Substring(idx+1).Split("&".ToCharArray());
                for (int i = 0; i < paramLst.Length; i++)
                {
                    string[] p = paramLst[i].Split("=".ToCharArray());
                    switch (p[0])
                    {
                        case "debug":
                            if (p[1] == "true")
                            {
                                isDebug = true;
                                //txtLogger.Visibility = Visibility.Visible;
                                debugRow.Height = new GridLength(100);
                                this.pivotMdxDesignerControl.BeginDataLoad += new EventHandler<Ranet.AgOlap.Controls.General.DataLoaderEventArgs>(pivotMdxDesignerControl_BeginDataLoad);
                            }
                            break;
                        default:
                            break;
                    }
                }
            }
        }

 add InitDebug(); method invoke in Init method;
 add method pivotMdxDesignerControl_BeginDataLoad();

void pivotMdxDesignerControl_BeginDataLoad(object sender, Ranet.AgOlap.Controls.General.DataLoaderEventArgs e)
        {
            if (isDebug)
            {
                txtLogger.Text += e.UserState;
            }
        }

 add private variable bool isDebug = false;
3. change file ranet-uilibrary-olap\UILibrary.Olap\Ranet.AgOlap\Controls\PivotMdxDesignerControl.cs
 add private variable public event EventHandler<DataLoaderEventArgs> BeginDataLoad;
 add event register in method Initialize() : m_ServerExplorer.OlapDataLoader.BeginDataLoad += this.BeginDataLoad;
4. change file UITest.Silverlight\Page.xaml
 add new TextBox control txtLogger at proper place

<Grid x:Name="LayoutRoot" Loaded="Init">
        <Grid.ColumnDefinitions>
            <ColumnDefinition />
        </Grid.ColumnDefinitions>
        <Grid.RowDefinitions>
            <RowDefinition/>
            <RowDefinition x:Name="debugRow" Height="0" /><!--here-->
        </Grid.RowDefinitions>
        <Samples:MyDesigner Grid.Row="0" Grid.Column="0" x:Name="pivotMdxDesignerControl" />
        <TextBox x:Name="txtLogger" Grid.Row="1" Grid.Column="0"/><!--here-->
    </Grid>

5. change file ranet-uilibrary-olap\UILibrary.Olap\Ranet.AgOlap\Controls\General\OlapDataLoader.cs
 add method invoke in LoadData(OlapActionBase schema, object state) : Raise_BeginDataLoad(new DataLoaderEventArgs(null, null, service.Endpoint.Address.Uri.ToString()));
 add method Raise_BeginDataLoad(DataLoaderEventArgs args)

void Raise_BeginDataLoad(DataLoaderEventArgs args)
        {
            EventHandler<DataLoaderEventArgs> handler = this.BeginDataLoad;
            if (handler != null)
            {
                handler(this, args);
            }
        }

 add public variable : public event EventHandler<DataLoaderEventArgs> BeginDataLoad;
6. change file ranet-uilibrary-olap\UILibrary.Olap\Ranet.AgOlap\Controls\General\IDataLoader.cs
 add variable in interface IDataLoader : event EventHandler<DataLoaderEventArgs> BeginDataLoad;
