Accepted answer

Here is my code in View at the bottom:
-----------------------------------------

<script>       alert('@TempData["myValue"].ToString()'); script>

-----------------------------------------

And Controller
-----------------------------------------
TempData["myValue"] = 354354;

-----------------------------------------

and it works !

Hi Sunny,

That was working fine, thank u.

If you give us only controller, how can we debug & check? as the issue is happening at runtime.

You cant, just leave it.

Jaganathan Bantheswaran13y ago
Please zip your project & upload.

Hi Teja,

Sasi,

Its not better approach to have all the values in ViewBag, use your own model/viewmodel instead of ViewBag.

Hi,

The one of the easiest way to achieve this is to return value from controller using ViewData.

For example:
```
if (SaveToDbOK) {     ViewData["Success"] = "Data was saved successfully.";    // Do other things or return view }
```
In your view, you can write in script block.

Another way to achieve the same is directly response the script from your controller.

public ActionResult UploadPropertyImage()
{
// Business logic....
return Content("");
}

Hope, this will help you out.

Please Don't forget to mark as answer if this post helps you.

ok, and where's your View?
Sunny Sharma13y ago
@Jaganathan Bantheswaran: Yes I agree.
Jaganathan Bantheswaran13y ago
@Sunny, ViewBag works, But If redirection occurs then the ViewData/ViewBag's value becomes null. Thats where TempData used.

How can I help you if i don't know what to do? Suggest you to share your code.

my view contains various dropdowns after clicking the button based on dropdowns i calculated one value.i want to show that value in alert box
Sunny Sharma13y ago
Sasi,

Show me your View and controller.

@ Jaganathan Bantheswaran: ViewBag will also work, TempData is a kind of temporary container which is emptied after the value is read.
Sasi Reddy13y ago
It is not displaying value
Jaganathan Bantheswaran13y ago
Try with TempData["myValue"] = "value" instead of ViewBag.
Sasi Reddy13y ago
I tried that one but it is displaying empty.
Sunny Sharma13y ago
Hi Sasi,

Keeping it simple, add the value to ViewBag use it in View, like:

Controller
-----------------
....
ViewBag.myValue = 45;// set your value here.
....
-----------------

View
-----------------

-----------------

Simple as that.

HTH :)
