Is it Possible to add two Get methods in 1 Action(asp.net core) ???

Is there any idea of how to place 2 get methods in 1 action method in asp.net core..

for eaxmple if we have dropdownlist and checkbox in a form how do we add both binding from database in one action methods.

Hii Jhon

This is why we use viewmodels, it seems like you are a beginner and want to learn the concept, so here i give you sample code to bind dropdown and checkbox in a single view.

public class MyViewModel
{
public List emplist { get; set; } // for dropdown
public List Checkboxs{get;set;} // for checkboxes
}
public class Employee_list
{
public int Empid { get; set; }
public string EmpName { get; set; }
}
public class CheckboxList_model
{
public string Text { get; set; }
public int Value { get; set; }
public Boolean Selected { get; set; }
}
public List GetEmployeeList()
{
var connection = GetConnection().GetSection("ConnectionStrings").GetSection("DefaultConnection").Value;
SqlConnection con = new SqlConnection(connection);
SqlCommand cmd = new SqlCommand("Select * From Employees", con);
con.Open();
SqlDataReader idr = cmd.ExecuteReader();
List Employees = new List();
if (idr.HasRows)
{
while (idr.Read())
{
Employees.Add(new Employee_list
{
Empid = Convert.ToInt32(idr["EmpoyeeId"]),
EmpName = Convert.ToString(idr["EmpName"]),
});
}
}
con.Close();
return Employees;
}
}
[NonAction]
public List ChkMRole()
{
// here you could get data from database
List chkRole = new List(){
new CheckboxList_model{ Text="Admin", Value = 1 ,Selected=false},
new CheckboxList_model{ Text="Vice-Admin", Value = 2 ,Selected=false},
new CheckboxList_model{ Text="Member", Value = 3 ,Selected=false }
};
return chkRole;
}
public IActionResult Index()
{
MyViewModel vm= new MyViewModel();
vm. Checkboxs=ChkMRole();
vm.emplist =GetEmployeeList();
return View(vm);
}
// view
@model ProjectName.Models.MyViewModel
@Html.DropDownListFor(model => model.emplist, new SelectList(Model.emplist, "Empid", "EmpName")
, new { @class = "form-control" })
class="text-center">
@for (int i = 0; i < Model.Checkboxs.Count(); i++)
{
@Html.CheckBoxFor(m => m.Checkboxs[i].Selected, new { @class = "" })
@Html.DisplayFor(m => m.Checkboxs[i].Text)
@Html.HiddenFor(m => m.Checkboxs[1].Value)
}

thank u sachin singh

Dear Jon John,

Yes of course it is possible.

Please check it with routing

[HttpGet("GetItem")]

[HttpGet("GetAllItem")]

Hi Jon,

You must be passing data to View through ViewModel you can create 2 list inside ViewModel. Then Create an instance and pass data to View.

public class MyViewModel{
public List<string> List1{get;set;}
public List<string> List2{get;set;}
}

To Call it in View

public ActionResult MyMethod(){
MyViewModel vm = new MyViewModel();
vm.List1 = ..//Data Filling Logic
vm.List2 = ..//Data Filling Logic
return View(vm);
}

Else,

You can pass data to View using ViewData or ViewBag

public ActionResult MyMethod(){
ViewData['List1'] = ..//Data Filling logic
ViewData['List2'] = ..//Data Filling logic
return View();
}
public ActionResult MyMethod(){
ViewBag.List1 = ..//Data Filling logic
ViewBag.List2 = ..//Data Filling logic
return View();
}

View Code:

@Html.DropDownList("MyList",new SelectList(Model.List1)) // Model.List1/ViewBag.List1/ViewData['List1']
@foreach (var item in Model.List2) // Model.List2/ViewBag.List2/ViewData['List2']
{
@Html.CheckBox(item,false) @(" "+item)
}

Okay you can bind data list in viewmodel in that list ...and then return it view you can see my this article this is of checkbox list add and edit example https://www.c-sharpcorner.com/article/multi-select-checkbox-dropdown-list-create-edit-in-net-core-3-1/

@khusbu Saini i get that but i want to know how we write code in get method of both checbox and dropdownlist in 1 action method..for eaxmple http[get] public iactionresult Index()-- in here

I think you can add both type lists as IDs array in Viewmodel and then bind those list to view with drodown and checkbox..so from this you can get both drop-down and checkbox list ids to your post method on controller.
