ASP.NET MVC render partial from the POST method - asp.net-mvc

Question

Problem
I have Telerik TabControl and each tab content is a partial view. Everything works smoothly when request is GET:
//
// GET: /ProductVersion/Translations
public ActionResult Translations(Guid id)
{
VersionEditTabViewModel model = CreateTranslationsViewModel(id);
return PartialView("Translations", model);
}
Now the problem is that on some tabs I have a Form that has controls that trigger submit event.
[HttpPost]
public ActionResult Translations(Guid id)
{
FormCollection formCollection = new FormCollection(Request.Form);
string message = string.Empty;
int languageId = int.Parse(formCollection["TranslationsLanguageList"]);
string action = formCollection["TranslationAction"];
if(action == Constants.translation_save)
{
_translationModel.SaveTranslations(formCollection);
message = "Translation information saved";
}
else if (action == Constants.translation_language_changed)
{
/*
PROBLEM: causes whole page to render, not partial
*/
return PartialView("Translations", model);
}
return RedirectToAction( ... updates the complete page not only partial ...);
}
My question is: how to render partial from the POST method? Because now with that source code tab content will be loaded to the WHOLE page, not inside tab.
Solution
I had to put DIV outside of the Ajax.Form and also I had incorrect submit on my DropDownList. What I did was that I created hidden submit button with Id and then I used jQuery to execute it's click event.

For additional reference, please refer to this question on SO:
MVC - Using Ajax to render partial view
This shows a complete implementation of the Ajax.BeginForm with surrounding DIV and inner form controls. You should be able to place this entire setup (DIV + Form + HTML Form Elements) in the Telerik Tab, like this:
<% Html.Telerik().TabStrip()
.Name("TabStrip")
.Items(tabstrip =>
{
tabstrip.Add()
.Text("Your Tab Text")
.Content(() =>
{%>
<div id="containerDiv" align="left">
<% using (Ajax.BeginForm("Example", "Controller/Action", new AjaxOptions { UpdateTargetId = "containerDiv" })){ %>
<%-- Render Partial here -->
<% } %>
</div>
<%});
Hope that helps.

I did my trough ajax form:
using (Ajax.BeginForm("*ActionName*", new { *parameter = ID* }, new AjaxOptions { UpdateTargetId = (*div i will update*), OnSuccess = "*JavaScript that executes on success*", OnComplete = "s*ame as on success*", InsertionMode = InsertionMode.Replace }))
and then i have
return PartialView("*PartialViewName*", model);
in post Action
And it works just fine, on post, action returns partial view and then ajax form replaces the content of the div specified in the UpdateTargetId with InsertionMode.Replace
