My dropdown selected value is not being posted to the controller

I am new to C# mvc. I have a simple form containing a dropdown list whose values are being populated from a ViewBag

@using (Html.BeginForm("GetSliderValues", "Slider",FormMethod.Post))
{
    @Html.DropDownList("dvalue",(IEnumerable<SelectListItem>)ViewBag.names) 
    <input type="submit" name="submit" value="Submit" />
}

After submitting the form I am trying to get the selected value in the Controller as 

[HttpPost]
public ActionResult GetSliderValues()
{
    ProviderName p = new ProviderName();
    p.Name = Request.Form["dvalue"];
    return View(p);   
}

But I am not receiving any value. p.Name is always being set to null.

Notice that you're not trying to POST data but GET it. That's why you need to use FormMethod.Get instead of FormMehod.Post.

then, just try to create a new SelectList instead of an IEnumerable of SelectListItem.

In your View:

@using (Html.BeginForm("GetSliderValues", "Slider",FormMethod.Get))
{
    @Html.DropDownList("dvalue",new SelectList(ViewBag.names))
    <input type="submit" name="submit" value="Submit" />
}

And then in your controller just Add an string parameter:

public ActionResult GetSliderValues(string dvalue)
{
    ProviderName p = new ProviderName();
    p.Name = dvalue;
    return View(p);   
}

Finally remove The [HttpPost] decorator and it should Work
