How to display another view in asp net core razor pages

Introduction

ASP.NET is a popular programming language used for building web applications. One common task in web development is displaying different views based on user actions or application logic. In this article, we will explore how to display another view in ASP.NET Core Razor Pages.

Using the RedirectToPage method

ASP.NET Core Razor Pages provides a convenient method RedirectToPage that allows us to to another page or view. This method takes the page name as a and automatically the user to that page.


public IActionResult OnPost()
{
    // Perform some logic here

    return RedirectToPage("AnotherPage");
}

In the above example, we have an action method called OnPost that gets executed when a form is submitted. After performing some logic, we use the RedirectToPage method to redirect the user to the “AnotherPage” view.

Passing data to the redirected view

Sometimes, we may need to pass data from the current view to the redirected view. ASP.NET Core Razor Pages allows us to this by using the property. TempData is a -like that stores data for the duration of a user's session.


public IActionResult OnPost()
{
    // Perform some logic here

    TempData["Message"] = "Hello from the current view";

    return RedirectToPage("AnotherPage");
}

In the above example, we set the value of the “Message” key in the TempData dictionary to “Hello from the current view”. This data will be available in the redirected view, allowing us to display it or use it for further processing.

Accessing the TempData in the redirected view

To access the data in TempData in the redirected view, we can use the TempData property again. TempData uses a key-value pair structure, so we need to retrieve the value using the same key that was used to store it.


public IActionResult OnGet()
{
    var message = TempData["Message"];

    return Page();
}

In the above example, we retrieve the value of the “Message” key from TempData and store it in the message variable. We can then use this variable to display the message in the redirected view.

Conclusion

In this article, we have explored how to display another view in ASP.NET Core Razor Pages. We have seen how to use the RedirectToPage method to redirect to a different page or view, and how to pass data between views using the TempData property. By these concepts, you can enhance the user experience of your web applications and provide dynamic content based on user actions or application logic.
