The app implements the PRG pattern whereby a search page is presented, the user enters a criteria, hits the search button and the result of the search is presented at the bottom of the same page. The items listed in the results table have a link that open

you don't show the code, but most likely you are binding get to a value type (non-nullable) that is required by default. so the url requires the parameter. make it a nullable type if you want it optional.
Hi Bruce. Thank you for taking the time to answer. I have posted my code. I can see it. If you can't please let me know how to make it visible to you. In the meantime I am pasting it raw below. Not sure where exactly to make the parameter optional; I tried
@ page "{fileSearchCriteriaAuto?} and it did not make a difference.
***Unformatted code
[TempData]
public string FileSearchCriteriaAuto { get; set; }
public void OnGet()
{
if (!String.IsNullOrEmpty(FileSearchCriteriaAuto))
{
FileSearchCriteria = JsonConvert.DeserializeObject<SearchCriteria>(FileSearchCriteriaAuto);
public async Task<IActionResult> OnPostAsync()
{
FileName = Request.Form["fname"].ToString().Trim();
var elements = Request.Form.Where(e => e.Key.Contains("criteria")).ToList();
ContentSearchCriteria = new List<string>();
foreach (var ele in elements)
{
ContentSearchCriteria.Add(ele.Value.ToString().Trim());
}
FileSearchCriteria = new SearchCriteria(FileName, ContentSearchCriteria.ToList());
I could not reproduce your issue.Could you share the razor view?And share more detailed code that could reproduce your issue.
Best Regards,
Rena

Getting error "Hmmm...can’t reach this page Try this Make sure you’ve got the right web address:...

Hello everyone!
My first post. Was thrown in the ring to write a razor app...
The app implements the PRG pattern whereby a search page is presented, the user enters a criteria, hits the search button and the result of the search is presented at the bottom of the same page. The items listed in the results table have a link that open a detail page, which has a "back" link to the first page. All that was working...I made some changes along the way and now when I run the app for the first time, it comes up. I enter the search criteria, hit the submit button and the page fails with
"Hmmm...can’t reach this page
Try this Make sure you’ve got the right web address: https://localhost:5001..."
Below is a simplified version of the code in the page model.
[TempData] public string FileSearchCriteriaAuto { get; set; } //...more code here public void OnGet() { if (!String.IsNullOrEmpty(FileSearchCriteriaAuto)) { FileSearchCriteria = JsonConvert.DeserializeObject<SearchCriteria>(FileSearchCriteriaAuto); HasSearch = FileSearchCriteria.FileName.Length > 0 || FileSearchCriteria.Criteria.Exists(c => c.Trim().Length > 0); ContentSearchCriteria = new List<string>(); ContentSearchCriteria.AddRange(FileSearchCriteria.Criteria); if (!(TempData == null)) { FileSearchCriteriaAuto = JsonConvert.SerializeObject(FileSearchCriteria); TempData["FileSearchCriteriaManual"] = FileSearchCriteriaAuto; if (TempData.ContainsKey("MatchedFilesJson")) { MatchedFiles = JsonConvert.DeserializeObject<List<FileProcessed>>(TempData["MatchedFilesJson"].ToString()); TempData.Keep(); } } FileName = FileSearchCriteria.FileName; } else { FileSearchCriteria = new SearchCriteria(string.Empty, 3); } } public async Task<IActionResult> OnPostAsync() { FileName = Request.Form["fname"].ToString().Trim(); var elements = Request.Form.Where(e => e.Key.Contains("criteria")).ToList(); ContentSearchCriteria = new List<string>(); foreach (var ele in elements) { ContentSearchCriteria.Add(ele.Value.ToString().Trim()); } FileSearchCriteria = new SearchCriteria(FileName, ContentSearchCriteria.ToList()); string criteria = JsonConvert.SerializeObject(FileSearchCriteria); await LoadFilesAsync(FileName); MatchedFilesJson = JsonConvert.SerializeObject(MatchedFiles); TempData["MatchedFilesJson"] = MatchedFilesJson; return RedirectToPage("/Index"); }NB: I have tried passing a parameter to the OnGet method, from a property decorated with the
. Then the browser cannot render the page, as if the link is broken.
Does anyone know why the page won't open? Thank you in advance!

you don't show the code, but most likely you are binding get to a value type (non-nullable) that is required by default. so the url requires the parameter. make it a nullable type if you want it optional.

Maybe, https is not being used. Maybe nothing is listening on TCP port 5001. Maybe the url is wrong.

but there is no:
in the sample code. the line you say breaks your code.
