Config file for Silverlight

1. Use ServiceReferences.ClientConfig file like app.config in C# application

- Add configuration in ServiceReferences.ClientConfig

eg)

<configuration>
    <appSettings>
      <add key="MAX_UPLOAD_SIZE" value="3145728" />
    </appSettings>
    <system.serviceModel>
    ....
    </system.serviceModel>
</configuration>

2. Create your own ConfigurationManager
- Add reference System.Xml.Linq;

eg)

public static class ConfigurationManager
{
    static ConfigurationManager()
    {
        AppSettings = new Dictionary();
        ReadSettings();
    }
 
    public static Dictionary AppSettings { get; set; }
 
    private static void ReadSettings()
    {
        string strKey = string.Empty;
        string strValue = string.Empty;
        XmlReaderSettings settings = new XmlReaderSettings();
        settings.XmlResolver = new XmlXapResolver();
        XmlReader reader = XmlReader.Create("ServiceReferences.ClientConfig");
        reader.MoveToContent();
        while (reader.Read())
        {
            if (reader.NodeType == XmlNodeType.Element && reader.Name == "add")
            {
                if (reader.HasAttributes)
                {
                    strKey = reader.GetAttribute("key");
                    if (!string.IsNullOrEmpty(strKey))
                    {
                        strValue = reader.GetAttribute("value");
                        AppSettings.Add(strKey, strValue);
                    }
                }
            }
        }
    }
}

3. Create property in your class

eg)

public class Consts
{
    public Int64 MAX_UPLOAD_SIZE
    {
        get
        {
            string MaxUploadSize = ConfigurationManager.AppSettings["MAX_UPLOAD_SIZE"];
            return int.Parse(MaxUploadSize);
        }
    }
}

4. Create instance in App.xaml

eg)
<local:Consts x:Key="Consts" />

5. Bind with StaticResource

eg)
<telerik:RadUpload MaxFileSize="{Binding Source={StaticResource Consts}, Path=MAX_UPLOAD_SIZE}" />
