Personally, I'd pop the result string into the ViewBag.
就个人而言，我会将结果字符串弹出到 ViewBag 中。
public ActionResult InsertDetails(FormCollection collection)
{
//DO LOGIC TO INSERT DETAILS
ViewBag.result = "Record Inserted Successfully!";
return View();
}
Then on the web page:
然后在网页上：
<p>@ViewBag.result</p>

My Suggestions
我的建议
There are following disadvantages while using the FormCollection
使用 FormCollection 有以下缺点
Point - 1
点 - 1
In case FormCollectionis being used...It will be mandatory to Type Castthe Primitive TypeValues un-necessarily because while getting the entry of specific Index of the System.Collections.Specialized.NameValueCollection, value being returned is of type String. This situation will not come in case of Strongly Typed View-Models.
如果FormCollection正在使用......这将是不必要Type Cast的Primitive Type值，因为在获取 的特定索引的条目时System.Collections.Specialized.NameValueCollection，返回的值是类型String。这种情况不会出现在 Strongly Typed 的情况下View-Models。

When you submit the form and goes to PostAction Method, and View-Modelas Parameter exists in the Action method, you have the provision to send back the Posted Values to you View. Otherwise, write the code again to send back via TempData/ViewData/ViewBag
当您提交表单并转到Post操作方法时，并且View-Model由于操作方法中存在参数，因此您可以将发布的值发送回给您View。否则，再次编写代码以通过TempData/ViewData/ViewBag

We have Data Annotations that can be implemented in View Modelor Custom Validations.
我们有可以在View Model或 中实现的数据注释Custom Validations。
ASP.Net MVC simplifies model validatons using Data Annotation. Data Annotations are attributes thyat are applied over properties. We can create custom validation Attribute by inheriting the built-in Validation Attribute class.
ASP.Net MVC 使用数据注释简化模型验证。数据注释是应用于属性的属性。我们可以通过继承内置的验证属性类来创建自定义验证属性。

Example you have the following HTML
示例您有以下HTML
<input type="text" name="textBox1" value="harsha" customAttr1 = "MyValue" />
Question: How can we access the value of customAttr1 from the above eg from inside the controller
问题：我们如何从上面访问 customAttr1 的值，例如从控制器内部
Answer: When a form get posted only the name and value of elements are posted back to the server. You can also use Hidden Fields to post the Attributes to Post Action method.
回答：当表单被发送时，只有元素的名称和值被发送回服务器。您还可以使用隐藏字段将 Attributes 发布到 Post Action 方法。
Alternatives: Use a bit of jQuery to get the custom attribute values, and post that along with the form values to action method
替代方案：使用一些 jQuery 来获取自定义属性值，并将其与表单值一起发布到操作方法
Another option is to rather put what you got in your custom attributes in hidden controls
另一种选择是将您在自定义属性中获得的内容放在隐藏控件中
That's the reason, I would always prefer to use View-Models
这就是原因，我总是更喜欢使用 View-Models

we can do it on Form inside view
我们可以在 Form 内部视图上完成
@using (Ajax.BeginForm("Action", "Controller", new AjaxOptions { HttpMethod = "POST", OnSuccess = "Showmessage" }))
[HttpPost]
public ActionResult Test(TestViewModel model)
{
return Json(new {isok=true, message="Your Message" });
}
function Showmessage(data)
{
$('#Element').html('Successfully Submitted');
}
