DropDownList Model 绑定 ASP.NET PagedList 视图中的 MVC

Question

I need to bind the model with the dropdownlist to create a custom sorting filters.
My view receives the "@model PagedList.IPagedList<EmployeeInvestments.Models.Registration>" as model.

A part of My View:-

@model PagedList.IPagedList<EmployeeInvestments.Models.Registration>
@using PagedList.Mvc;
@{
    ViewBag.Title = "AdminDashboard";
}

<div>
    Financial Year:
    <select>
        @foreach(var item in Model)
        {
            <option>@Html.ValueFor(ModelItem=>item.FinancialYear)</option>
        }
    </select>

        Name:
        <select>
            @foreach (var item in Model)
            {
                <option>@Html.ValueFor(ModelItem => item.Name)</option>
            }
        </select>
        Employee ID:
        <select>
            @foreach(var item in Model)
            {
                <option>@Html.ValueFor(ModelItem=>item.employeeID)</option>
            }
        </select>
</div>

I tried the above approach for getting items in dropdownlist but I need unique values in the dropdownlist.

The image shows what exactly I want to achieve in View

I have created a table in the view that lists all users and certain details. So, I need to sort the users based on the filters available in dropdownlist.

Please refer to image for getting a clear picture of what I need to achieve.

Answer 1

To filter by distinct year:

Financial Year:
<select>
    @foreach(var item in Model.Select(x => x.FinancialYear).Distinct())
    {
        <option>@Html.ValueFor(ModelItem=>item.FinancialYear)</option>
    }
</select>

Answer 2

To get Unique date you can use groupby

<select>
    @foreach(var item in Model.GroupBy(i=>i.FinancialYear).Select(x => x.Key))
    {
        <option>@Html.ValueFor(ModelItem=>item)</option>
    }
</select>
