ASP.NET: How to call webservice with parameters through extJs HttpProxy class.

In this post I am going to explain how we can call a C# asp.net webservice with parameters through extJs HttpProxy class.

You have to do this:

var storeName = new Ext.data.Store

({

proxy: new Ext.data.HttpProxy

({

url: 'webserviceName/methodName,

method: 'POST'

}),

baseParams: {parameter1: p1,parameter2 p2},

reader: readerName,

});

In webservice you have to write:

[WebMethod]

[ScriptMethod(ResponseFormat = ResponseFormat.Json, XmlSerializeString = false)]

public void GetData(int p1, int p2)

{

// outString is a JSON formated string

Context.Response.Write(outString);

}
