AlertTagHelper

Generate bootstrap 4 styled alerts from html side or c# backend side.

Sample use cases of AlertTagHelper, based on bootstrap's alerts.

Installation

Install via nuget package manager, 

            Install-Package LazZiya.TagHelpers
Then add LazZiya.TagHelpers to _ViewImports.cshtml 
            
            @addTagHelper *, LazZiya.TagHelpers

C# backend generated alerts

            using LazZiya.TagHelpers.Alerts;

public class IndexModel : PageModel
{
    public void OnGet()
    {
        TempData.Success("This is success alert message from c# backend!");
    }
}

And on razor side we need to add one tag helper to render all alerts that is coming from backend:

<alert></alert>

Result :

All alert methods:


TempData.Success("This is success alert message from c# backend!");
TempData.Primary("This is primary alert message from c# backend!");
TempData.Secondary("This is secondary alert message from c# backend!", "Helloo");
TempData.Info("This one has no close button!", "Info", false);
TempData.Warning("This is warning alert message from c# backend!");
TempData.Danger("This is danger alert message from c# backend!");
TempData.Light("This is light alert message from c# backend!");
TempData.Dark("This is dark alert message from c# backend!");
