title: Salesforce show all cases based on criteria in visualforce
body: <p>All,</p>
  
  <p>I am attempting to show all cases that meet certain criteria in salesforce using visual force page, then I would like to use that data in a gantt chart.  I do know much about coding, but trying based on user manuals.  This visualforce page comes back without any case information.</p>
  
  <pre><code>&lt;apex:page standardController="Case" &gt;
      &lt;apex:form &gt;
          &lt;apex:pageBlock &gt;  
              &lt;apex:pageMessages /&gt;
              &lt;apex:pageBlockButtons&gt; 
                  &lt;apex:commandButton value="Save" action="{!save}"/&gt;
              &lt;/apex:pageBlockButtons&gt;
              &lt;apex:PageBlockTable value="{!Case}" var="c"&gt;
                  &lt;apex:column value="{!c.Account}"/&gt;
                  &lt;apex:column value="{!c.Number}"/&gt;
                  &lt;apex:column value="{!c.Owner}"/&gt;
                  &lt;apex:column headerValue="Install Date"&gt;
                      &lt;apex:inputField value="{!a.Planned_Install_Date__c}"/&gt;
                  &lt;/apex:column&gt;
              &lt;/apex:PageBlockTable&gt;
          &lt;/apex:pageBlock&gt;
      &lt;/apex:form&gt;
  &lt;/apex:page&gt;
  </code></pre>
