MVC4 load data into partial views - asp.net-mvc

Question

my main (MyProfile) view contains links that when user clicks on the link the partial view loads in the div with existing data from DB that can be updated by the user.
#Ajax.ActionLink("Update 1", "Update1", new { email = #ViewBag.Email }, new AjaxOptions() { HttpMethod = "GET", UpdateTargetId = "divCurrentView", InsertionMode = InsertionMode.Replace })
#Ajax.ActionLink("Update 2", "Update2", new { email = #ViewBag.Email }, new AjaxOptions() { HttpMethod = "GET", UpdateTargetId = "divCurrentView", InsertionMode = InsertionMode.Replace })
<div id="divCurrentView">
</div>
Partial Views: example:
_Update1:
#model ViewModels.Update1
#using (Html.BeginForm())
{
#Html.AntiForgeryToken()
#Html.ValidationSummary(true)
#Html.HiddenFor(model => model.id)
#Html.LabelFor(model => model.Name)
#Html.TextBoxFor(model => model.Name)
<input type="submit" value="Update" />
}
_Update2:
#model ViewModels.Update2
#using (Html.BeginForm())
{
#Html.AntiForgeryToken()
#Html.ValidationSummary(true)
#Html.HiddenFor(model => model.id)
#Html.LabelFor(model => model.Website)
#Html.TextBoxFor(model => model.Website)
<input type="submit" value="Update" />
}
In the Controller:
public PartialViewResult Update1(string email)
{
var model = populate the viewmodel
return PartialView("_Update1",model);
}
public PartialViewResult Update2(string email)
{
var model = populate the viewmodel
return PartialView("_Update2",model);
}
It doesnt mean the user will click on all the links when accessing the main view.
I want to get feedback if my way is correct OR should I load all the data once when the user gets to MyProfile View and store the data in the session and when each partial view gets loaded data gets loaded from the session?
This would avoid calling the db every time partilaview gets loaded or is there a better approach?
Thanks,
UPDATE:
I tried to use Cache as suggested but the problem the data is store globally. If multiple users login and try to view/update the data, the data is identical for all of them Am I missing something?
This is what tried:
public PartialViewResult Update1(string email)
{
var cc = HttpRuntime.Cache.Get("cinfo");
Update1VM model = null;
if (cc == null)
{
model = populate the viewmodel
HttpRuntime.Cache.Insert("cinfo", model);
}
else
{
model = (Update1VM)cc;
}
return PartialView("_Update1", model);
}

Use Html.ActionLink in way you use is good solution. It makes controller simple and reuseble. You can easily add and remove views without changes in controller. It is easy to put them in diffrent view.
Generally it's more flexible solution.
If you afraid of calling the db every time you can always use some caching, but in your example it will query db only when user really need it and click it.
If you put this in one view it will be more complicated, more messy and less error prone.
