Asp net mvc pass input value from view to controller

ASP.NET MVC is a powerful framework for building web applications. One common task in web is passing input values from a view to a controller. In this article, we will explore different ways to this in ASP.NET MVC, with examples.

Method 1: Using Form Submission

One way to pass input values from a view to a controller is by using form submission. This involves creating a form in the view and submitting it to the controller. Let's take a look at an example:


@using (Html.BeginForm("ActionName", "ControllerName", FormMethod.Post))
{
    

@Html.TextBoxFor(model => model.InputValue)

}

In the above example, we use the `Html.BeginForm` helper method to create a form. The `ActionName` and `ControllerName` parameters the action method and controller where the form data will be submitted. The `TextBoxFor` helper method creates an input for the `InputValue` property of the model.

When the form is submitted, the input value will be sent to the specified action method in the controller. You can then access the input value in the controller using the model binding feature of ASP.NET MVC.

Method 2: Using Query Parameters

Another way to pass input values from a view to a controller is by using query parameters. This involves appending the input value as a query in the URL when navigating to the controller action. Let's see an example:


@{
    var inputValue = "example";
    var url = Url.Action("ActionName", "ControllerName", new { inputValue = inputValue });
}

In the above example, we use the `Url.Action` helper method to generate the URL for the controller action. We pass the input value as a query parameter using the `new { inputValue = inputValue }` syntax.

When the link is clicked, the browser will navigate to the specified controller action with the input value as a query parameter. You can then access the input value in the controller action using the `Request.QueryString` property.

Method 3: Using AJAX

If you want to pass input values from a view to a controller without refreshing the entire page, you can use AJAX. This involves making an asynchronous request to the controller action and sending the input value in the request payload. Let's take a look at an example:




In the above example, we use to capture the input value and send it to the controller action using an AJAX request. We create a new `XMLHttpRequest` object and set the request method, URL, and request headers. We then send the input value as a JSON payload using the `send` method.

In the controller action, you can access the input value using the model binding feature of ASP.NET MVC.

These are just a few examples of how you can pass input values from a view to a controller in ASP.NET MVC. Depending on your specific , you may choose one method over the others. It's to understand the pros and cons of each approach and choose the one that best suits your .
