Support Multiple TaxPayer
TaxPro GST User Control Library provides support for single TaxPayer ApiSetting and ApiLoginDetails store in default Json files, out-of-box. GstSession object would be internally created by reading these settings and there is no need to set GstSession property of API Enabled control.
If host application needs to support multiple TaxPayer, it needs to store ApiLoginDetails for multiple TaxPayer and needs to implement TPSession (creating different session object for each TaxPayer). Same logic may be implemented for all GSTR controls. Using TPSession name is not compulsary. Developer may use any convenient name and assign this object to GstSession property of all API Enabled controls (in host form/page constructor.)
Sample C# Code:
using System;
using RestSharp;
using TaxProGST.API;
using TaxProGST.Controls;
using System.Reflection;
namespace TaxProGST
{
public class TPSession : GSTSession
{
public int TaxPayerId { get; set; }
public string TaxPayerName { get; set; } //If required
/// <summary>
/// Constructor for use in case of Non TaxPayer Specific API
/// </summary>
public TPSession() : base(true, false)
{
if (ApiSetting.ASPName?.ToUpper() == "GSTN_SANDBOX")
UserIP = "123.123.123.123";
else
UserIP = "DeskTopApp";
}
/// <summary>
/// Constructor for TaxPayerID dependencyt injection in GSTSession
/// </summary>
/// <param name="TPID"></param>
public TPSession(int TPID) : base(true, false)
{
LoadLoginSettings(TPID);
if (ApiSetting.ASPName?.ToUpper() == "GSTN_SANDBOX")
UserIP = "123.123.123.123";
