Try to access URL parameter inside razor page

I send an URL through an email to access a form with the parameter name "email". I try to access the email parameter inside the razor page.

This is what I pass as URL:

https://localhost:44339/Home/LecturerRegister?email=pasindu@gmail.com'

Then I access the email parameter by using ViewContext.RouteData.Values["email"]

<input type="email" required class="form-control" name="Email" value="@(ViewContext.RouteData.Values["email"])">

But I can't access the parameter value by this method. It's return nothing.

The recommended way to work with data passed in URLs is to use Model Binding. In this example, you should add a public property to your PageModel class representing the email and mark it with the BindProperty attribute, opting in to binding in GET requests:

[BindProperty(SupportsGet=true)]
public string Email { get; set; }

Then use an input tag helper to generate your input, assigning the public the asp-for attribute:

<input asp-for="Email" class="form-control" />

the tar will take case of generating the correct name and attributes and will assign the value from the bound property.

Note: you could also use Request.Query["email"], but model binding is the correct way to do this.

Can you try this code:

value="@ViewContext.RouteData.Values["email"].ToString()"
