how pass string argument eventhandler?

viewcontroller(a) written event handler

    public event eventhandler valuechanged;       void responsecompleted(object sender, commoncode.responseeventargs e){         this.invokeonmainthread (delegate {           if (valuechanged != null) {         valuechanged (this, new eventargs (e.responsedata)); // e.responsedata string datatype.          }      });     } 

viewcontroller(b)

relateddatasource.valuechanged += delegate {  response data viewcontrollera } 

you can use generic eventhandler. example:

public event eventhandler<string> valuechanged;  void responsecompleted(object sender, commoncode.responseeventargs e){     this.invokeonmainthread (delegate {       var handler = valuechanged;     if (handler != null)         handler(this, e.responsedata);     }); }  relateddatasource.valuechanged += (s, responsedata) => {     //your data in responsedata variable }
