How to display .cshtml content based on ActionLink in .NET MVC? - c#

My Register.cshtml page contains both Patient and Doctor registration. I have written a script to check if the user is Patient then displays only information relevant to patient and vice-versa.
If click on register patient then patient information only should insert into the database and the vice-versa for doctor registration.
Currently, If I register patient then it should not take specialization data into database because it is doctor's specific information.
Another problem is that, If I change the specialization or city value from drop down then it throws error:
The ViewData item that has the key 'Specialization' is of type
'System.String' but must be of type 'IEnumerable'.
Exception Details: System.InvalidOperationException: The ViewData item
that has the key 'Specialization' is of type 'System.String' but must
be of type 'IEnumerable'.
Source Error: #Html.DropDownListFor(x
=> Model.Specialization, Model.Specializations, htmlAttributes: new { #class = "form-control form-control-sm" })

{
await SignInManager.SignInAsync(user, isPersistent: false, rememberBrowser: false);
return RedirectToAction("Index", "Home");
}
AddErrors(result);

return View(model);

I think the best way to solve it write two register action(doctor,Patient)that doctor and Patient have own view

About question
I can't run your code locally.
These operations can be implemented through JS.
I can show my tools.
This is the function gif:
Solution:
Select and add options as a whole.
// index.cshtml
<div>
#await Component.InvokeAsync("AutoAddListValue")
</div>
//Component
#model List<string>
<h3>Default page</h3>
<div>
<div>
<p>Lists</p>
<select name="select" class="" id="ComponentSelectId" onclick="ComponentSelectClick()">
<option id="ComponentOptionId" style="width:auto">ComponentTest</option>
#if (Model.Count != 0)
{
int count = Model.Count();
for (int item = 0; item < count; item++)
{
<option id="option">#Model[item].ToString()</option>
}
}
</select>
</div>
<div>
<input id="ComponentTestJsInput" class="d-none" value="132323" type="text" />
<input id="ComponentBtnDisplay" value="Add" type="button" class="btn btn-primary" onclick="ComponentBtnDisplayClick()">
<input id="ComponentBtnAdd" value="Add" type="button" class="btn btn-primary d-none" onclick="ComponentBtnAddClick()">
</div>
</div>
Bind data for components.
public class AutoAddListValueViewComponent : ViewComponent
{
private readonly SchoolContext _context;
public AutoAddListValueViewComponent(SchoolContext context)
{
_context = context;
}
public async Task<IViewComponentResult> InvokeAsync(
int maxPriority, bool isDone)
{
string MyView = "Default";
var items = await GetListAsync();
return View(MyView, items);
}
public async Task<List<string>> GetListAsync()
{
return await _context.Test.Select(o => o.Name).ToListAsync();
}
}
Using JS code to realize page interaction.
var ComponentBtnDisplayClick = function () {
$('#ComponentBtnAdd').removeClass("d-none");
$('#ComponentTestJsInput').removeClass("d-none");
$('#ComponentBtnDisplay').addClass("d-none");
}
var ComponentBtnAddClick = function () {

Screen shot:
ActionResult:
[HttpPost]
public ActionResult AddCompany(MainModel mainModel)
{
try
{
Country_Bind();
if (ModelState.IsValid)
{
dp obj = new dp();
if (obj.AddNewCompany(mainModel))
{
ViewBag.Message = "Company added successfully";
}
}
return View();
}
catch
{
return View();
}
}
Country code:
public void Country_Bind()
{
DataSet ds = dblayer.Get_Country();
List<SelectListItem> coutrylist = new List<SelectListItem>();
foreach (DataRow dr in ds.Tables[0].Rows)
{
coutrylist.Add(new SelectListItem { Text = dr["CountryName"].ToString(), Value = dr["CountryID"].ToString() });
}
ViewBag.Country = coutrylist;
}
You are currently calling the Country_Bind() method as the first statement inside your httppost action method. You actually need to do that when you want to rerender the dropdown list when re rendering the same view.
If you are not doing an ajax post,You should follow the PRG pattern. On successful save of the data, you should redirect to the GET action method which render the view. If the Modelstate validation fails, that is when you return the same view (so that you can show the validation message to user) and you need to repopulate the dropdown data before that.
When you do a Redirect, ViewData does not work to transfer messages.Use TempData instead.
[HttpPost]
public ActionResult AddCompany(MainModel mainModel)
{
try
{
if (ModelState.IsValid)
{
dp obj = new dp();
if (obj.AddNewCompany(mainModel))
{
TempData.Message = "Company added successfully";
return RedirectToAction("CompanyList");
}
}
// We need to repopulate the data needed for rendering dropdown
Country_Bind();
return View(mainModel);
}
catch(Exception ex)
{
// to do : Make sure to log the error
return View("Error");
}
}
In your case, when you do an ajax post returning a redirect result does not makes sense. You may return the url to the next page if needed as part of a json response and use that in your ajax calls success/done event handler and do appropriate things (redirect to the new page/show a message to user)
[HttpPost]
public ActionResult AddCompany(MainModel mainModel)
{
try
{
if (ModelState.IsValid)
{
dp obj = new dp();
if (obj.AddNewCompany(mainModel))
{
return Json(new { Message="Company added successfully"});
}
}
return Json(new { Message="Validation errors!"});
}
catch(Exception ex)
{
// must log the exception
return Json(new { Message="Error "});
}
}
Make sure to update your success/done event handler of your ajax call to read the response (the json and do something like showing message to user/hiding or showing the next tab)
I also noticed an issue with your ajaxifying code. Since you are making an ajax form submission, you should prevent the default form submit behavior by calling the event.preventDefault method.
$("#SaveCompany").click(function (e) {
e.preventDefault();
GetInfo();
});
I would also recommend to use a flat-lean view model specific for the view. So your properties will not be nested level and when you use the helper methods (TextBoxFor etx), It will generate the correct input field names and you do not need to manually build the Js object you want to send. You may simply use the jquery serialize() method on your form object and send that as the data for the ajax call.
