    <p>So I am trying to have a button when clicked it sends data to an sql server. I thought i could just create a form that would only have a submit button and I would handle that submit button in my home controller.</p> <p>My html is as such:</p> <pre><code>&lt;body&gt; &lt;div style="border: solid; max-width: 300px; margin-left: auto; margin-right: auto"&gt; @using(Html.BeginForm()) { &lt;input type="submit" value="Vote"/&gt; } &lt;/div&gt; &lt;/body&gt; </code></pre> <p>in my home controller i thought it was supposed to handle the form such as:</p> <pre><code>using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using System.Data.SqlClient; namespace WAgermanClub.Controllers { public class HomeController : Controller { [HttpPost] public ActionResult add(string vote1) { SqlConnection vote1connection = new SqlConnection("user id=userid;" + "password=validpassword;server=o5z5dpwpzi.database.windows.net;" + "Trusted_Connection=yes;" + "database=wagermanclub_votes; " + "connection timeout=30"); try { vote1connection.Open(); } catch (Exception g) { Console.WriteLine(g.ToString()); } try { SqlDataReader myReader = null; SqlCommand myCommand = new SqlCommand("select * from table", vote1connection); myReader = myCommand.ExecuteReader(); while (myReader.Read()) { Console.WriteLine(myReader["Vote1"].ToString()); } } catch (Exception i) { Console.WriteLine(i.ToString()); } SqlCommand vote1command = new SqlCommand("INSERT INTO table (Column1, Vote1) " + "Values (1, 'Vote1' + 1)", vote1connection); vote1command.ExecuteNonQuery(); try { vote1connection.Close(); } catch (Exception h) { Console.WriteLine(h.ToString()); } } } } </code></pre> <p>It all looks fine except for I get an error saying that in the add(string vote1) not all code paths return a value. What am I doing wrong? I do not have that great of a grip on html forms but I feel that once I get this it will lead to a better understanding. </p> <p>All help appreciated! Thanks!</p>

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.
