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);
}

The JSON formated string could be like this:
string outString = "{\"Status\":[";
foreach(DataRow dr in dt.Rows)
{
if(dt.Rows.Count>i+1)
outString = outString + "{" + "\"Status\":\"" + dr["name"] + "\"," + "\"status_id\":\"" + dr["status_id"] + "\"},";
else
outString = outString + "{" + "\"Status\":\"" + dr["name"] + "\"," + "\"status_id\":\"" + dr["status_id"] + "\"}]}";
i++;
}
if (dt.Rows.Count <= 0)
outString = "";
string outString = "{\"Status\":[";
foreach(DataRow dr in dt.Rows)
{
if(dt.Rows.Count>i+1)
outString = outString + "{" + "\"Status\":\"" + dr["name"] + "\"," + "\"status_id\":\"" + dr["status_id"] + "\"},";
else
outString = outString + "{" + "\"Status\":\"" + dr["name"] + "\"," + "\"status_id\":\"" + dr["status_id"] + "\"}]}";
i++;
}
if (dt.Rows.Count <= 0)
outString = "";
