Richtext Limit Amount of Rows/characters of the field that displays in a Visualforce page

Hello. I am making a 'feed' type visualforce page for my home dashboard, and i am displaying the most recent 5 records. Within those records, there is a richtext type field, which is the "Comment". I am trying to only display the first 5 rows of the field data (not the whole field as the info can get to long and stretch the page). Is there a way to limit the number of rows/characters which display on a richtext field type. I know i can do it on a standard text field, but not a richtext? The field is

 

value="{!t.miiHelpDeskT2__Comment__c}"

 

Thanks in advance

 

Here is my VF

 

<apex:page standardController="miiHelpDeskT2__Ticket__c" showheader="false" sidebar="false" extensions="TicketCommentFeedList">
<html>
<style type="text/css">
a:link    {
  /* Applies to all unvisited links */
  text-decoration:  none;
  font-weight:      bold;
  color:            blue;
  } 
a:visited {
  /* Applies to all visited links */
  text-decoration:  none;
  font-weight:      bold;
  color:            #f0f;
  } 
a:hover   {
  /* Applies to links under the pointer */
  text-decoration:  underline;
  font-weight:      bold;
  color:            #fff;
  } 
a:active  {
  /* Applies to activated links */
  text-decoration:  underline;
  font-weight:      bold;
  color: white;
  } 
.ticket {font-family:arial,Georgia,Serif; font-size: 12px; font-weight:bold; color:#6699CC}
</style>
  <apex:repeat value="{!TicketCommentFeedList}" var="t" rows="5">
      <table width="100%" border="1" cellpadding="5">
      <tr>
        <td>
        <a href="https://ap1.salesforce.com/{!t.miiHelpDeskT2__Ticket__c}" target="_parent">
        <apex:outputText styleClass="ticket" value="{!t.miiHelpDeskT2__Ticket_Number__c}"/>
        </a>&nbsp;:&nbsp;
        <apex:outputText style="font-size:11px;" value="{!t.miiHelpDeskT2__Subject__c}"/>&nbsp;:&nbsp;
        <apex:outputText style="font-size:11px;" value="{!t.Contact_Who_Made_Comment_Name__c}" escape="false"/>&nbsp;@&nbsp;<apex:outputText style="font-size:11px;" value=" {!t.miiHelpDeskT2__Created_Date_Time__c}"></apex:outputText><br></br><br></br><apex:outputText style="font-size:11px;" value="{!t.miiHelpDeskT2__Comment__c}" escape="false"/>
        
        </td>
      </tr>
      </table> 
  </apex:repeat> 
</html>   
</apex:page>

 

Here is my class

 

public class TicketCommentFeedList {

    private ApexPages.StandardController stdCtrl;
    
    public TicketCommentFeedList(ApexPages.StandardController controller)

    {

        stdCtrl=controller;

    }

    List<miiHelpDeskT2__Ticket_Comment__c> myList;

    Public List<miiHelpDeskT2__Ticket_Comment__c> getTicketCommentFeedList() {

myList = [SELECT Id, Name, miiHelpDeskT2__Ticket__c, miiHelpDeskT2__Active__c, miiHelpDeskT2__Comment__c, miiHelpDeskT2__Contact_Name__c, miiHelpDeskT2__Contact_Who_Made_Comment_Email__c, miiHelpDeskT2__Contact_Who_Made_Comment__c, miiHelpDeskT2__Created_Date_Time__c, miiHelpDeskT2__Is_Member_Comment__c, miiHelpDeskT2__Is_Ticket_Answered__c, miiHelpDeskT2__Public__c, miiHelpDeskT2__Send_Customer_Notification__c, miiHelpDeskT2__Subject__c, miiHelpDeskT2__Ticket_Manager_Email__c, miiHelpDeskT2__Ticket_Manager_Name__c, miiHelpDeskT2__Ticket_Number__c, miiHelpDeskT2__ID_Historic__c, Ticket_Comment_Name_Historic__c, Ticket_Subject__c, Ticket_Description__c, Contact_First_Name__c, Contact_Who_Made_Comment_Name__c FROM miiHelpDeskT2__Ticket_Comment__c WHERE miiHelpDeskT2__Active__c = True ORDER BY miiHelpDeskT2__Created_Date_Time__c DESC ];

    /// ORDER BY CAN BE ASC OR DESC 

    return  myList;

    }

    public static testmethod void Test1()

    {

    Project_Cost__c p=new Project_Cost__c();

    ApexPages.StandardController sc = new ApexPages.standardController(p);

           

    TicketCommentFeedList Tcfl=new TicketCommentFeedList (sc);

    Tcfl.getTicketCommentFeedList();

    }     

}

Hi,

 

You can use the left method for displaying the specific number of character

 

For example:

 

value="{!Left(t.miiHelpDeskT2__Comment__c,50)}"

 

Did this answer your question? If not, let me know what didn't work, or if so, please mark it solved.
