The mvc html begin form link to the action method of the controller that renders the form. The Html helper BeginForm has several overrides.
The below example uses four parameters such as the name of the action method, controller to submit the form, routevalues attribute and form method.
Mvc Html BeginForm example: (with area)
@using (@Html.BeginForm("Create", "Category", new { area = "admin" }, FormMethod.Post))
{
@Html.Partial("_Category", Model)
}
Here, the controller that renders the form is Category, Action method is created and area is Admin. If you want to go different area, then modify the area field and set new area.
Without area:
@using (@Html.BeginForm("index", "Home", new { area = "" }, FormMethod.Post))
{
// call the controller
}
If you want access the home controller, outside the Areas from the admin area you should specify the empty quotes for the parameter.
