  how to check which event caused the post back in ASP.net MVC

  Nov 03, 2009 07:47 AM|LINK

  I have one View and one Controller in my ASP.net MVC Application.

  I have one "Submit" button & one "Cancel" button in my view. 

  When I click any of the botton below action will be triggered.

  AcceptVerbs(HttpVerbs.Post)

  public ActionResult Result()

  {

  }

  Now the Question is how i will know in my  public ActionResult Result() , whether post back caused because of "Submit" or "Cancel"   ??

  Hi,

  You will get the object triggering the submit. I mean you will get it in form collection.

  I modified your code such that the ActionResult is accepting FormCollection

  [AcceptVerbs(HttpVerbs.Post)]
  public ActionResult Result(FormCollection form)
  {
      if(form["Submit"] != null)
      {
          // Submit click
      }
      else if(form["Cancel"] != null)
      {
          // Cancel click
      }
  }

  where submit and cancel are names of input buttons of type submit

  Thanks it worked for me. I got one more solution like

  [AcceptVerbs(HttpVerbs.Post)]
  public ActionResult Result()
  {
      if(Request.Params.ToString().IndexOf("btnSubmit") > 0)
      {
          // Submit click
      }

  
      else 

      {
          // Cancel click
      }
  }

  Why should you look for all params and finding with index of?? You can check for null. And I recommend it. You can directly get it from Form, if you are not passing form collection...

  Request.Form["btnSubmit"] != null
