Asp net core button asp-action

ASP.NET is a popular programming language used for developing web applications. It provides a powerful framework for building dynamic and interactive websites. One common in web development is to create buttons that perform certain actions when clicked. In this article, we will explore how to create buttons in ASP.NET Core and specify the action to be performed when the button is clicked.

To create a button in ASP.NET Core, we can use the `

Example 1: Creating a Button with asp-action

Consider the following code snippet:



In this example, we have created a button with the text “Save”. The `asp-action` attribute is set to “Save”, means that when the button is clicked, the “Save” action method will be called.

It's to note that the action method specified in the `asp-action` attribute should be defined in the corresponding controller. Otherwise, an will occur.

Example 2: Passing Parameters to the Action Method

Sometimes, we may need to pass additional parameters to the action method when the button is clicked. We can achieve this by using the `asp-route-*` attributes. Let's see an example:



In this example, we have added the `asp-route-id` attribute to the button. This attribute specifies that the value of the “id” should be set to “123” when the button is clicked. The “Delete” action method will be called with the specified parameter.

Example 3: Using a Form to Data

In some cases, we may need to submit data to the server when the button is clicked. We can achieve this by wrapping the button a form element. Let's take a look at an example:


In this example, we have created a form with the `asp-action` attribute set to “Create”. When the button is clicked, the form will be to the server using the HTTP POST method, and the “Create” action method will be called.

By using the `asp-action` attribute in combination with attributes like `asp-route-*` and `

`, we can create buttons in ASP.NET Core that perform specific actions when clicked. These examples demonstrate some of the common scenarios you may encounter while developing web applications using ASP.NET Core.

Remember to always define the corresponding action in the controller to handle the button clicks and perform the desired actions.
