Hi Sunny, That was working fine, thank u.

Jaganathan Bantheswaran · Answer

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

Sasi Reddy · Answer

Sasi Reddy · Answer

Hi Teja, In alet u r displaying message,along with that i want to display some value.can u tell me that

Jaganathan Bantheswaran · Answer

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

Robbinson · Answer

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. var successmsg= ' '; alert(successmsg); Another way to achieve the same is directly response the script from your controller. public ActionResult UploadPropertyImage() { // Business logic.... return Content(" alert('Save Successfully'); "); } Hope, this will help you out. Please Don't forget to mark as answer if this post helps you.

Sunny Sharma · Answer

ok, and where's your View?

Sunny Sharma · Answer

@ Jaganathan Bantheswaran : Yes I agree.

Jaganathan Bantheswaran · Answer

@Sunny, ViewBag works, But If redirection occurs then the ViewData/ViewBag's value becomes null. Thats where TempData used.

Sunny Sharma · Answer

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

Sasi Reddy · Answer

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 Sharma · Answer

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 Reddy · Answer

It is not displaying value

Jaganathan Bantheswaran · Answer

Try with TempData["myValue"] = "value" instead of ViewBag.

Sasi Reddy · Answer

I tried that one but it is displaying empty.

Sunny Sharma · Answer

Hi Sasi, Keeping it simple, add the value to ViewBag use it in View, like: Controller ----------------- .... ViewBag.myValue = 45;// set your value here. .... ----------------- View ----------------- alert('@ViewBag.myValue'); ----------------- Simple as that. HTH :)
