[@ALICEFELIX1]

Thank you so much such a detailed description of Parameter passing and navigation in Blazor, it is exactly what i was looking for for my Maui Blazor hybrid application. Thanks alot saved me hours of agony

[@ProMakerDev]

awesome video you

[@upulwaruna.abeysinghe]

Great Venkat,

[@jobiraw]

Thumbs Up....Dear venkat will this series include authentication and authorization??

[@azkarelsabah8781]

Thank You Venkat

[@coolwaterdvr]

Thank you Venkat. 🙏

[@rdrgox]

Thx, excelente todo el material

[@aliajmat]

Not expected this... :( Great. But why not You are showing an error or No record found in the EMployeeDetail page ?? why id= id ?? "1" ;

[@azkarelsabah8781]

when he remove id from url page display that there is no route by this url then , he add new route and this code id= id ?? "1" ;

[@djedaaa2232]

I think that better solution would be to redirect to component on route "/" using NavigationManager, if Id is not specified in url..

[@setiadisudrajat5031]

Venkat you are God!!!🙏

[@ypwygk652]

There is no god but God... Venkat is not a god, rather he is a creature that will die.. But God is alive and does not die.. And rely upon the Ever-Living who does not die, and exalt [ Allah ] with His praise. And sufficient is He to be, with the sins of His servants, Acquainted -

NullReferenceException: Object reference not set to an instance of an object. EmployeeManagement.Pages.EmployeeDetails.BuildRenderTree(RenderTreeBuilder __builder at these Layout = null; do you guys getting this Error?

[@zorigdavaag.8354]

i have to initialize the Employee property like this public Employee Employee { get; set; } = new Employee(); this corrected my issue

[@politikusmihaly8716]

@@zorigdavaag.8354 That's true it solves the problem but why is this? We didn't initilaize the Employees property in the EmployeeListBase class like here and still worked, so why is that?

[@politikusmihaly8716]

Okay I guess it is because we check if it's null at EmployeeList component.

[@azkarelsabah8781]

yes , you must forgot to take an object from Employees public Employees Employee{get; set;} = new Employees()

[@armanx2]

So basically you need to "recreate" repository pattern at front -end to be able to do some calls, seems to me like it's somewhat a overkill :) here is where Blazor is somewhat disappointing for me...

[@jayantlalguru6780]

The OnInitializedAsync is called twice. This is by design as far as I am aware. This calls the API twice. Is there a way to stop calling the API twice?

[@Siemensc01]

That happened to me also. Apparently, if you have 2 routings in a component, OnInitializedAsync is called twice. Try with only one routing in the component and check again. It does not make any sense to me, but it behaves that way.

[@johnnieperez4790]

The same is true with employee public property! in fact, it seems like each time that you use inside (like, name) the debugger goes to EmployeeDetailComponentBase and reads the property like a round-trip. @kudvenkat

[@azkarelsabah8781]

at _Host @(await Html.RenderComponentAsync(RenderMode.ServerPrerendered)) replace RenderMode.ServerPrerendered by RenderMode.Server

[@vahidalizadeh5836]

How can we check if Employees is null and then redirect to NotFound Page?

[@ivanb8662]

5:59 protected override async Task OnInitializedAsync()

[@hintsoftware]

how to pass complex objects as parameter ?

[@adelashraf1577]

[@hamadelmalik8424]

how can i insert multi record

[@BarriDuty]

how to show department name instead of id

[@jobiraw]

@Barri Duty you can Create relationship b/n the two entities then use Include(e => e.Departments); this way you have all the department information.....

[@diabader6251]

@page "/employeedetails/{id?}" For Optional Parameter :)
