I want to handle an event on item selected in the dropdown list
I Googled a bit and people say there is no regular event handler like normal ASP or WinForm application

I’m not familiar with javascript and jquery but i could understand a code

Answer 1

You could put this DropDown inside a form and use javascript to subscribe to its onchange event and manually submit this form:

@using (Html.BeginForm("SomeAction", "SomeController"))
{
    @Html.DropDownList("process", Model.Items, new { onchange = "this.form.submit();" })
}

this will POST the selected value to the SomeAction where you could retrieve it:

[HttpPost]
public ActionResult SomeAction(string process)
{
    // the process argument will contain the selected value from the dropdown
    ...
}
