Salesforce show all cases based on criteria in visualforce - salesforce

Question

All,
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.
<apex:page standardController="Case" >
<apex:form >
<apex:pageBlock >
<apex:pageMessages />
<apex:pageBlockButtons>
<apex:commandButton value="Save" action="{!save}"/>
</apex:pageBlockButtons>
<apex:PageBlockTable value="{!Case}" var="c">
<apex:column value="{!c.Account}"/>
<apex:column value="{!c.Number}"/>
<apex:column value="{!c.Owner}"/>
<apex:column headerValue="Install Date">
<apex:inputField value="{!a.Planned_Install_Date__c}"/>
</apex:column>
</apex:PageBlockTable>
</apex:pageBlock>
</apex:form>
</apex:page>

Answer 1

You need an apex controller class to get data from Salesforce to the visual force page. Something like this:
Visual Page:
<apex:page standardController="Case" controller="MyCaseController">
<apex:form >
<apex:pageBlock >
<apex:pageMessages />
<apex:pageBlockButtons>
<apex:commandButton value="Save" action="{!save}"/>
</apex:pageBlockButtons>
<apex:PageBlockTable value="{!Cases}" var="c">
<apex:column value="{!c.Accountid}"/>
<apex:column value="{!c.CaseNumber}"/>
<apex:column value="{!c.OwnerId }"/>
</apex:PageBlockTable>
</apex:pageBlock>
</apex:form>
Controller:
public class MyCaseController {
public list<Case> cases {get;set;}
public MyCaseController(){
cases = [select id, accountid, CaseNumber, OwnerId from case];
}
}
You should be able to accommodate the code to your needs.
