    <p>Is there any event available for Dropdownlist like onChange, etc. in MVC4? Do we have to use Javascript/jQuery in order to make some manipulations like DropwowlistSelectedItemChanged, etc? Or there is a way only using the Razor or MVC4 features?</p> <p>On the other hand, could you please give me some examples how can I retrieve data and change a label's text with this data according to a Dropdownlist Selected Value? For example when selecting a City from Dropdownlist, I want to get an address data from database by using the selected city id and then show retrieved address on a label. I would be appreciated if you clarify me about the issue above and give me an example to achieve this.</p> <p><strong>Controller:</strong></p> <pre><code>private void PopulateMeetingsDropDownList(object selectedMeetings = null) { var meetingsQuery = repository.Meetings .Join(repository.Cities, m =&gt; m.MeetingCityId, c =&gt; c.CityID, (m, c) =&gt; new { CityID = c.CityID, CityName = c.CityName, MeetingDate = m.MeetingStartDate } ) .OrderBy(x =&gt; x.CityID) .AsEnumerable() .Select( i =&gt; new { CityID = i.CityID, DisplayValue = string.Format( "{0} ({1:dd MMMM yyyy})", i.CityName, i.MeetingDate) } ).ToList(); ViewData["MeetingId"] = new SelectList(meetingsQuery, "CityID", "DisplayValue", selectedMeetings); } </code></pre> <p><strong>View:</strong></p> <pre><code>&lt;label&gt;Meeting&lt;/label&gt; @Html.DropDownListFor(m =&gt; m.MeetingId, ViewData["MeetingId"] as SelectList,"---- Select ----", new { name = "meetingId", id = "meetingId"}) </code></pre>

    2. COAFAIK, MVC does not deal in events, only submits and gets. You will have to use javascript to handle drop down list changes, but you can call server-side code with ajax.

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
