Invalidade ASP.Net Cache to reload dependent user controls

If you have two user controls (ascx) in the asp.net cache and need to update a user control if the other changes, you can use the following method:

On the dependent ascx, that needs to refresh:
PartialCachingControl pcc= Parent as PartialCachingControl;
StaticPartialCachingControl spcc= Parent as StaticPartialCachingControl;

if (pcc !=null) pcc.Dependency=new CacheDependency(null, new string[]{"HighLightChange"});

This will create a cache dependency on the HighLightChange string.

On the ascx that needs to invalidate the cache:
HttpRuntime.Cache.Insert("HighLightChange","true");

The change on the HighLightChange will invalidate the cache dependency of the user control that must do a data refresh.

How to get the ApplicationPath in ASP.Net?

path += "/";

XML Serialization

This is a sample of how to serialize a class in .Net

using System;

using System.Xml;
using System.Xml.Serialization;
using System.IO;
using System.Text;

namespace WindowsApplication1
{
public class AppConfig
{
private long _Code;
private string _Description;
private string _Obs;
public long Code
{
get {return _Code;}
set { _Code = value;}
}

public string Description
{
get {return _Description;}
set { _Description = value;}
}

public string Obs
{
get {return _Obs;}
set { _Obs = value;}
}

}

///

/// Summary description for Configuration.
///

[XmlInclude(typeof(AppConfig))]
public class Configuration
{
private AppConfig _AppConfig = null;
public Configuration()
{
_AppConfig = new AppConfig();
}

public void SetConfiguration(long code, string desc, string obs)
{
_AppConfig.Code = code;
_AppConfig.Description = desc;
_AppConfig.Obs = obs;
}

public void Searialize()
{
XmlTextWriter writer = new XmlTextWriter("test.xml", Encoding.Unicode);
writer.Formatting = Formatting.Indented;
XmlSerializer serializer = new XmlSerializer(typeof(AppConfig));
serializer.Serialize(writer, _AppConfig);
writer.Close();
}
}
}
