Dynamically Add Fields to Razor Form

Dynamically Add Fields to Razor Form

In Razor, you can dynamically add fields to a form using the HtmlHelper class and @foreach loop. Here's an example of how to do it:

@using (Html.BeginForm("MyAction", "MyController")) { @foreach (var item in Model.Items) { <div> <label for="@item.FieldName">@item.FieldName</label> <input type="@item.FieldType" name="@item.FieldName" value="@item.FieldValue" /> </div> } <input type="submit" value="Submit" /> }

In this example, we use the Html.BeginForm method to create a form that posts to the MyAction action in the MyController controller. We then use a foreach loop to iterate over the fields in the Model.Items collection, which contains the fields to be dynamically added to the form.

For each field in the collection, we create a div element that contains a label element with the field name, and an input element with the field type and value. The name attribute of the input element is set to the field name, which allows the form data to be posted to the server with the correct field name.

Finally, we add a submit button to the form using an input element of type submit.

By using the HtmlHelper class and @foreach loop in Razor, you can dynamically add fields to a form based on data in a collection or other data source.
