Not getting url last id

Question

User1052662409 posted

Hi All,

Currently my url as http://localhost:65099/Event/Create/93726

After clicking a button I want to go to another actionresult with this id 93726

 @Html.ActionLink("Save as Draft", "SaveAsDraft", "Event", null, new { @class = "btn aqua block bottom15" })

But I am unable to get this id. I am trying to access it as follows.

int id = Convert.ToInt32(Request.Url.Segments.Last());

 public ActionResult SaveAsDraft(EventModel EM)
        {
           
          

            try
            {

                int id = Convert.ToInt32(Request.Url.Segments.Last());
             // doing something
}             
            catch (Exception ex)
{
  Web.MsgBox(ex.ToString());
}

As I put a breakpoing and it shows url as http://localhost:65099/Event/SaveAsDraft. That is why I am not getting the id.

Please suggest. How to get the id and execute the SaveAsDraft actionresult with this id.

Your Id in the View should be in the Model of the View.( possibly EventModel ? ) And the Model is filled in the action

So you will have 

int id = Model.<ID property of the Model>;

Simply add the route parameter.

 @Html.ActionLink("Save as Draft", "SaveAsDraft", "Event", new {id = id}, new { @class = "btn aqua block bottom15"})

The code above assumes the name of the route parameter is "id" but you have not posted Create action or View so there is no way to provide accurate code.

Hi demoninside9,

I suggest you could get the id in the “Create” Action and store it in ViewBag, then on the Create page, pass the Id to the Actionlink by ViewBag.

@Html.ActionLink("Save as Draft", "SaveAsDraft", "Event", new { id = ViewBag.id }, new { @class = "btn aqua block bottom15"})

This is my edit method, when a row clicked for edit.

 public ActionResult Edit(string id, string Type, string Act)
        {
            if (Type == "Event" && Act == "Edit")
            {
                objDB.Requesr_Master_For_Event_SelectById(Convert.ToInt32(id));
                Session["Act"] = Act;
                RouteValueDictionary rvd = new RouteValueDictionary();
                rvd.Add("id", id);
                return RedirectToAction("Create", "Event", rvd);
            }
            return View("Load");
        }

Then it redirects to Create Actionresult with create view. There is a button on Create view 

 @Html.ActionLink("Save as Draft", "SaveAsDraft", "Event", null, new { @class = "btn aqua block bottom15",id="id" })

I want when this button is clicked it should go the action result SaveAsDraft with the id.

It goes but without id.

Your Id in the View should be in the Model of the View.( possibly EventModel ? ) And the Model is filled in the action

So you will have 

int id = Model.<ID property of the Model>;

 through this method (objDB.Requesr_Master_For_Event_SelectById(Convert.ToInt32(id));) I am filling the EventModel but again I did not find the Model id with value.

Hi demoninside9,

Your ActionLink is incorrect, you should modify it like this.

@Html.ActionLink("Save as Draft", "SaveAsDraft", "Event", new  { id = ViewBag.id }, new { @class = "btn aqua block bottom15"})

Test with the following code:

public ActionResult Edit(string id)
        {           
            RouteValueDictionary rvd = new RouteValueDictionary();
            rvd.Add("id", id);
            return RedirectToAction("Create", "Event", rvd);           
        }

        public ActionResult Create(int id)
        {
            //var id = rvd["id"];
            ViewBag.id = id;
            return View();
        }      

        public ActionResult SaveAsDraft()
        {
            return View();
        }

Sorry, I put the route parameter in the wrong place in my post.
