title: Pass aspx form value to aspx.cs variable
body: <p>How do you pass an aspx form value to aspx.cs variable. 
  When I am on page 1 and select item 1, I'd like the value of PROC1 to be sent to the next page. I don't know how to accept it.</p>
  
  <p><strong>aspx form (page1.aspx)</strong></p>
  
  <pre><code>&lt;select&gt;
    &lt;option value="" disabled="disabled" selected="selected"&gt;Please select a name&lt;/option&gt;
    &lt;option value="PROC1"&gt;item 1&lt;/option&gt;
    &lt;option value="PROC2"&gt;item 2&lt;/option&gt;
  &lt;/select&gt;
  &lt;input type="submit" value="Submit" /&gt;
  </code></pre>
  
  <p><strong>receiving c# class (page2.aspx)</strong></p>
  
  <pre><code> protected void Page_Load(object sender, EventArgs e)
   {
        // I want to know how to capture the value of PROC1 
        // so I can use it as a variable on this new page
   }
  </code></pre>
