i have View Named Index i want to pass data get by GuidId. in Model and View Bag ... after enter Id how do this
public IActionResult Index()
{
return View();
}
public async Task<IActionResult> GetDS(Guid Id)
{
var url = string.Empty;
url = ApiEndpoint.serviceUrl + ApiEndpoint.GetDS + Id;
var data = await ApiService.GetAsync<DSModel>(url).ConfigureAwait(false);
url = ApiEndpoint.serviceUrl + ApiEndpoint.GetDSL + Id;
var data2 = await ApiService.GetAsyncCollection<DSLDetails>(url).ConfigureAwait(false);
ViewBag.DSL = data2;
return View("Index", data);
}
html error shows in HTML Side
#foreach (var item in #ViewBag.DSL)
{
<tr>
<td>
#item.Name
</td>
}
ERROR NullReferenceException: Object reference not set to an instance of an object.

+
#foreach (var item in #ViewBag.DSL)
You are getting this exception because #ViewBag.DSL is null in foreach loop. Please make sure that you are storing data in viewbag from server side in action menthod.
And second thing try this code:
#if(ViewBag.DSL != null)
{
foreach (var item in ViewBag.DSL)
{
<tr>
<td>
#item.Name
</td>
</tr>
}
}

I'm pretty new to working with Array Lists and would like to learn how to display data from the Controller that has an Array in the method to the MVC Razor Page. I'm creating a login that works just fine, but would like to display captured data from Active Directory to the UserLoginData.CSHTML page. I read that the best way is through the model. Any help would be greatly appreciated! (I just want the ArrayList in a table on the Razor data Page.)
Controller:
enter code here
public ActionResult UserLoginData(string username, string LblUserName, string
UserName, ArrayList AuthorizationGroups)
{
UserLoginModel model = new UserLoginModel();
UserName = username;
ViewBag.UserName = UserName;
model.UserName = UserName;
model.LblUserName = model.UserName;
model.AuthorizationGroups = AuthorizationGroups;
foreach (var item in AuthorizationGroups)
{
// Console.WriteLine(item);
model.item = item;
}
return View(model);
}
Model (Properties):
//Labels for UserLoginData:
public string LblUserName { get; set; }
public string LblTitle { get; set; }
public string LblPlantLocation { get; set; }
public string LblUserLoggedInTimeStamp { get; set; }
public string LblUserLoggedOutTimeStamp { get; set; }
public string LblDisplayName { get; set; }
public string LblEmail { get; set; }
//For the ArrayList of MemberGroups.
public ArrayList AuthorizationGroups { get; set; }
public ArrayList YardDogUserGroupMembers { get; set; }
public ArrayList MemberOfUserGroups { get; set; }
public ArrayList YardDogAdminGroupMembers { get; set; }
public object item { get; set; }
Razor CSHTML:
enter code here
#model PW_Login.Models.UserLoginModel
#{
Layout = null;

Just create TempData[] in the controller from one controller action result to another and then into the model also. After that you can access the TempData and keep it as needed for that session. Then on the Login Data Page, loop through the objects from the TempData or model properties to display in labels.
enter code here
#model PW_Login.Models.UserLoginModel
#{
Layout = null;
string UserName = TempData["UserName"].ToString();
string PlantLocation = TempData["UserPlantLocation"].ToString();
string UserLoggedInTimeStamp =
TempData["UserLoggedInTimeStamp"].ToString();
//Get the TempData Sessions and write them out.
var SecurityGroups = TempData["SecurityGroups"];
var MemberOfUserGroups = TempData["MemberOfUserGroups"];
var YardDogAdminGroupMembers = TempData["YardDogAdminGroupMembers"];
var YardDogUserGroupMembers = TempData["YardDogUserGroupMembers"];
TempData.Keep(UserLoggedInTimeStamp.ToString());
TempData.Keep(SecurityGroups.ToString());
TempData.Keep(MemberOfUserGroups.ToString());
TempData.Keep(YardDogAdminGroupMembers.ToString());
TempData.Keep(YardDogUserGroupMembers.ToString());
// PW_Login.Models.UserLoginModel LoginModel;
// LoginModel.SecurityGroups = SecurityGroups;

I'm trying to return a count of row's from a stored procedure in SQL. I've been working at this for hours now. I'm at a complete loss.
SQL Code: Returns result of 49 when run in SQL.
begin
select Count (EmployeeID)
from dbo.Employees
Where (Employees.Active = 'True')
end
Component Code:
#attribute [Authorize(Roles = "Admin")]
#using System.Collections;
#using WahlenDataAccessLibrary;
#using WahlenDataAccessLibrary.Models;
#using BlazorApp1.Models;
#inject IEmployeesData employeeData;
<div class="widget">
<h5 class="widget--title">Active Employees</h5>
<div class="widget--body">
<p class="widget--number">
<span>#employeeCount</span>
Active Employees
</p>
</div>
</div>
#code {
private string employeeCount { get; set; }
//private IEmployeeModel employeeCount = new EmployeeModel();
protected override async Task OnInitializedAsync()
{
var count = await employeeData.EmployeeCount();
//string employeeCount = await employeeData.EmployeeCount();
string employeeCount = count.ToString();
Console.WriteLine(employeeCount);
if (employeeCount != null)
{
Console.WriteLine("generic value");
}
else
{
Console.WriteLine("no value");
}
}
}
DataFile Code: To get the value from stored procedure.
public async Task<string> EmployeeCount()
{
var employeeCount = await _db.LoadValue("dbo.spWidget_EmployeeCount", "DefaultConnection");
return employeeCount.ToString();
}
}
The DataFile where 'LoadValue' is used. This is linked back to my SqlDataAccess File which uses this code.
public async Task<string> LoadValue(string storedProcedure, string connectionStringName)
{
string connectionString = _config.GetConnectionString(connectionStringName);
using (IDbConnection connection = new SqlConnection(connectionString))
{
var data = await connection.QueryAsync(storedProcedure,
commandType: CommandType.StoredProcedure);
return data.ToString();
}
}
When the application is running the console writes.
System.Collections.Generic.List`1[System.Object]
no value
The
System.Collections.Generic.List`1[System.Object]
comes from
var data = await connection.QueryAsync(storedProcedure,
commandType: CommandType.StoredProcedure);
return data.ToString();
the var data is actually an object. Callint .ToString() on a object will print out the type of the object (if the method is not over written).
Please check if the QueryAsync has a generic version. Usually it does and will make a type cast for you in the background. Try something like QueryAsync<int>. Or try to find the rigth method (with a single return item, instead of a list) on your ORM/db provider.
From the current context it is not possible to tell what db provider you are using.
I'm going to update the code here, as I've got it working.
Task<IEnumerable> was more so the answer here. If you have an sql query that is simply counting rows, this is how you access that data on Blazor on your front end. You can return the value as a string.
My sqlaccess file code now looks like this.
public async Task<IEnumerable<int>> LoadValue(string storedProcedure, string connectionStringName)
{
string connectionString = _config.GetConnectionString(connectionStringName);
using (IDbConnection connection = new SqlConnection(connectionString))
{
var data = await connection.QueryAsync<int>(storedProcedure,
commandType: CommandType.StoredProcedure);
return data;
}
}
And this is on the front end component.
private string employeeCount { get; set; }
protected override async Task OnInitializedAsync()
{
employeeCount = await employeeData.EmployeeCount();
Console.WriteLine(employeeCount);
if (employeeCount != null)
{
Console.WriteLine("generic value");
}
else
{
Console.WriteLine("no value");
}
I am always getting null value in jsp page textbox. I have defined name attribute in index.jsp page and fetching value using <%=session.getAttribute()%>.
Here is index.jsp
<tr>
<td>First Name</td>
<td>
<input type="text" required="" name="firstname" value="<%=session.getAttribute("firstname")%>"/>
</td>
</tr>
In below UploadServletClass.java, session is defined
public class UploadServletClass extends HttpServlet{
PrintWriter out = null;
Connection con = null;
PreparedStatement ps = null;
HttpSession session = null;
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException,IOException{
response.setContentType("text/plain;charset=UTF-8");
try{
out = response.getWriter();
session = request.getSession();
...
}
}
}
This is loginScript.jsp
<%
String zfid = request.getParameter("zid");
String fname = request.getParameter("firstname");
...
if (rs.next()) {
session.setAttribute("zfid", zfid); //used ${sessionScope.zfid} to display value into textbox and it is successful.
session.setAttribute("firstname",fname); //failed to display value in textbox
//out.println("welcome " + userid);
//out.println("<a href='logout.jsp'>Log out</a>");
response.sendRedirect("home.jsp");
}
Completely new on .Net core from MVC5, so how does download file works with .NET Core? I have tried writing down code but it has errors. Thanks in advance to the helpers.
Controller
public ActionResult Download()
{
string[] files = Path.Combine(_hostingEnvironment.WebRootPath, "uploads");
for (int i = 0; i < files.Length; i++)
{
files[i] = Path.GetFileName(files[i]);
}
ViewBag.Files = files;
return View();
}
public FileResult DownloadFile(string fileName)
{
var filepath = Path.Combine(_hostingEnvironment.WebRootPath, "uploads");
return File(filepath, LineMapping.GetMimeMapping(filepath), fileName);
}
View
<h2>Downloads</h2>
<table>
<tr>
<th>File Name</th>
<th>Link</th>
</tr>
#for (var i =0; i <= Model.Count -1; i++) {
<tr>
<td>
#Model[i].ToString()
</td>
<td>
#Html.ActionLink("Download", "Download", new { ImageName=#Model[i].ToString() })
</td>
</tr>
}
The code as written will not even compile because Path.Combine does not return a list of files. You will also get parsing errors in your view because you reference Model but you don't have a model. Also, your parameter ImageName doesn't match your action's parameter name. Several other issues with the code too (using Count on an array - use Count() or Length.
I think you are trying to do something like this?
Controller
public ActionResult Download()
{
string[] files = Directory.GetFiles(Path.Combine(_hostingEnvironment.WebRootPath, "uploads"));
for (int i = 0; i < files.Length; i++)
{
files[i] = Path.GetFileName(files[i]);
}
return View(files);
}
public FileResult DownloadFile(string fileName)
{
var filepath = Path.Combine(_hostingEnvironment.WebRootPath, "uploads", fileName);
return File(filepath, "application/pdf", fileName);
}
View
<table>
<tr>
<th>File Name</th>
<th>Link</th>
</tr>
#for (var i = 0; i <= Model.Length - 1; i++)
{
<tr>
<td>
#Model[i].ToString()
</td>
<td>
#Html.ActionLink("Download", "DownloadFile", new { fileName = #Model[i].ToString() })
</td>
</tr>
}
</table>
I am using this post as reference
I am trying to get the Model that I passed to the view to post back to the HttpPost method of the controller when the input is clicked. However, the model, which in this case is just List, is null when it posts back.
I have included my code for reference. This is just a project for testing random stuff out so I apologize for the crappy code.
I have the following View code: (showing the whole code for completness)
#{
ViewBag.Title = "Home Page";
}
#using TestApp.MyObjects
#model List<Contact>
#Ajax.ActionLink("Show About", "About", new { id = "1" }, new AjaxOptions { InsertionMode = InsertionMode.Replace, UpdateTargetId = "contentDiv" })
#Ajax.ActionLink("Show Contact", "Contact", new AjaxOptions { InsertionMode = InsertionMode.Replace, UpdateTargetId = "contentDiv" })
<div id="contentDiv"></div>
#using (Html.BeginForm())
{
<table>
#foreach (Contact c in Model)
{
<tr>
<td>
<button aboutnum0 = "#c.someValues[0]" aboutnum1 = "#c.someValues[1]" aboutnum2 = "#c.someValues[2]" class="nameButton">#c.name</button>
</td>
</tr>
}
</table>
<input value="#Model[0].name" />
<input value="#Model[0].name" />
<div id ="aboutContentDiv"></div>
<input type="submit" />
#ViewBag.myCoolValue
}
<script type="text/javascript">
$("button").click(function () {
$("#aboutContentDiv").empty();
$("#aboutContentDiv").append($("<div></div>").load("Home/About/" + $(this).attr("aboutnum0")));
$("#aboutContentDiv").append($("<div></div>").load("Home/About/" + $(this).attr("aboutnum1")));
$("#aboutContentDiv").append($("<div></div>").load("Home/About/" + $(this).attr("aboutnum2")));
});
</script>
The Following is my Comtroller Code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using TestApp.MyObjects;
namespace TestApp.Controllers
{
public class HomeController : Controller

{
ViewBag.Message = "Modify this template to jump-start your ASP.NET MVC application.";
Contact c = new Contact();
c.name = "Some Name";
c.someValues = new List<string>();
c.someValues.Add("1");
c.someValues.Add("2");
c.someValues.Add("3");
Contact c1 = new Contact();
c1.name = "Some Name1";
c1.someValues = new List<string>();

return PartialView("About",a);
}
public PartialViewResult Contact()
{

return PartialView("Contact");
}
}
}
Based on your reply to my comment, you need something like this:
// you can use foreach and have a counter variable or this
for (int i = 0; i < Model.Count; i++)
{
// you do not want to use a partial view so let's do it this way
// put this in an appropriate place in your code
// like inside a tr or div, it's up to you
#Html.TextboxFor(m => m[i].name)
}
