如何将值从控制器动作方法传递到局部视图

Question

Here I tried using TempData to pass data from controller action method to partial view. But it does not work.

My Controller Code

public class PropertyController : Controller
{
    public ActionResult Index()
    {
        return View();
    }


    public ActionResult GetRequestReport()
    {
        List<ReportsInfo> reportsList = reportsManager.GetRequestReport(UserName, Locality, "usp_GetResults");
    int count = reportsList.Select(x => x.UserId).Distinct().Count();
    TempData["Count"] = count;
        return PartialView("_Partial1", reportsList);
    }

    public ActionResult Test(string id)
    {
        switch (id)
        {
            case "tab1":
                return PartialView("_Results");
            case "tab2":
                return PartialView("_Results2");
        }

        return new EmptyResult();
    }

}

Index.cshtml

<div id="div-for-partial">
                </div>


    $(function () {
        $('.tab').click(function () {
            var id = this.id;
            $.get('@Url.Action("Test")', { "id": id }, function (data) {
                $('#div-for-partial').html(data);
                $('.mvc-grid').mvcgrid();
            });
        });
    });

_Results Partial View

   @TempData["Count"]
<br />
 <div id="reportList">
                    @Html.AjaxGrid(Url.Action("GetRequestReport", "Property"))
                </div>

_Partial1 Partial View

@model Project.Models.ReportsInfo
@(
        Html.Grid(Model)
            .Build(columns =>
            {

                columns.Add(model => model.ApproverName).Titled("Approver Name");

            })
            .Empty("No records found.")
            .Sortable()
            .Pageable(pager =>
            {
                pager.RowsPerPage = 15;
            })
)

I have even tried view bag but no luck is there any way to achieve it. Basically I want to pass count of results in TempData and use in partial view

Answer 1

public ActionResult GetRequestReport()
    {
        List<ReportsInfo> reportsList = reportsManager.GetRequestReport(UserName, Locality, "usp_GetResults");
    int count = reportsList.Select(x => x.UserId).Distinct().Count();
    ViewData["Count"] = count;
        return PartialView("_Partial1");
    }

In Partial1 partial View, you can get count in a count variable as shown below and use it where ever you want to.

@(
        int count=(int)ViewData["Count"];

        Html.Grid(Model)
            .Build(columns =>
            {

                columns.Add(model => model.ApproverName).Titled("Approver Name");

            })
            .Empty("No records found.")
            .Sortable()
            .Pageable(pager =>
            {
                pager.RowsPerPage = 15;
            })
)

Answer 2

you never called GetRequestReport() before calling Results partial view, how do you expect to get the value of count passed to Results partial view. Please verify what you are asking.
