Returning a partial view from a controller and injecting it into a
specific section of the page using an 
Ajax.BeginForm is a common pattern in ASP.NET MVC for dynamic content updates without reloading the whole page.
Submit a form using AJAX (Ajax.BeginForm)Return a PartialView from the controllerInject the returned HTML into a DOM element specified via UpdateTargetId
Controller Code
public ActionResult SubmitForm(MyViewModel model)
{
    if (ModelState.IsValid)
    {
        // Perform save or processing logic
        // Return a partial view to update part of the page
        return PartialView("_SuccessMessage", model);
    }
    // If validation fails, return a partial with errors or re-render the form
    return PartialView("_FormPartial", model);
}
Notes:
_SuccessMessage.cshtml and _FormPartial.cshtml are partial views (no layout).The return type is ActionResult, returning PartialView(...).
Client-Side View Code (Razor)
@model MyViewModel
andlt;div id="formContainer"andgt;
    @using (Ajax.BeginForm("SubmitForm", "Home", new AjaxOptions
    {
        HttpMethod = "POST",
        UpdateTargetId = "formContainer", // Where to inject the result
        InsertionMode = InsertionMode.Replace,
        OnSuccess = "onSuccess",
        OnFailure = "onFailure"
    }))
    {
        @Html.EditorFor(m =andgt; m.Name)
        andlt;input type="submit" value="Submit" /andgt;
    }
andlt;/divandgt;
Required Scripts:
andlt;script src="~/Scripts/jquery.js"andgt;andlt;/scriptandgt;
andlt;script src="~/Scripts/jquery.unobtrusive-ajax.js"andgt;andlt;/scriptandgt;
Partial View Example: _SuccessMessage.cshtml
andlt;div class="alert alert-success"andgt;
    Thank you, @Model.Name. Your submission was successful.
andlt;/divandgt;
Optional JavaScript Callbacks
function onSuccess(result) {
    console.log("AJAX Success:", result);
}
function onFailure(xhr, status, error) {
    console.log("AJAX Failure:", error);
    alert("Something went wrong.");
}
End-to-End Flow
User fills the form and clicks SubmitAjax.BeginForm:
Hijacks form submission via JavaScriptSends form data to the controller using AJAX
Controller:
Processes dataReturns a partial view result (HTML only) or JSON data (parse in
onSuccess function)
Client:
Injects the partial view HTML into the element with id="formContainer" via
UpdateTargetId
Tips and Gotchas
Ensure jquery.unobtrusive-ajax.js is loaded after jQueryYour partial views should not include layout (_Layout.cshtml)UpdateTargetId must match the DOM element where you want to inject
