[SalesForce] Display Specific Picklist Value Based on Criteria

I created an apex method that dynamically gets and displays all the values of a picklist field as options based on a criteria (criteria 1)

Values: Value1, Value2

But there are other two requirements which I am having some difficulty solving with:

when criteria 2 is achieved, the picklist must only display Value 1 as the option
when criteria 3 is achieved, the picklist must only display Value 2 as the option

How can I do this?

Meanwhile, here's the method I created for criteria 1:

public List<SelectOption> getValues()
{
   List<SelectOption> options = new List<SelectOption>();
   Schema.DescribeFieldResult fieldResult =
   Object1__c.Picklist_Field__c.getDescribe();
   List<Schema.PicklistEntry> ple = fieldResult.getPicklistValues();

   for( Schema.PicklistEntry f : ple)
   {
      options.add(new SelectOption(f.getLabel(), f.getValue()));
   }       
   return options;
}

Assuming you will always have only 2 values in the picklist

public List<SelectOption> getValues()
{
    List<SelectOption> options = new List<SelectOption>();
    Schema.DescribeFieldResult fieldResult =
        Object1__c.Picklist_Field__c.getDescribe();
    List<Schema.PicklistEntry> ple = fieldResult.getPicklistValues();
    // test for criteria 1
    if(**condition 1**){
        options.add(new SelectOption(ple[0].getLabel(),ple[0].getValue()));
        return options;
    }

    // test for criteria 2
    if(**condition 2**)
    {
        options.add(new SelectOption(ple[1].getLabel(),ple[1].getValue()));
        return options;
    }

  // Else return both the values

    for( Schema.PicklistEntry f : ple)
    {
        options.add(new SelectOption(f.getLabel(), f.getValue()));
    }       
    return options;
}

Do not use inline styles for this. Instead use CSS.

And don't use JS to remove Options from the Select. Use Apex code.

So the way to do it would be something along these lines:

Page:

<style type="text/css">
.low-discount {
  color: green;
}

.high-discount {
  color: red;
}
</style>

.....

<apex:selectList id="Disc" size="1" multiselect="false" value="{!results.Discount}" }">
  <apex:repeat value="{!discounts}" var="discount">
    <option class="{!discount < 12 ? 'low-discount' : 'high-discount'}">
      {!discount}
    </option>
  </apex:repeat>
</apex:selectList>

And write a controller method getDiscounts that returns a list of numbers that are the discount values. Something like this:

public List<Integer> getDiscounts() {
  //  get data somehow into familyDiscount

  // use a set to make each value unique
  Set<Integer> retVal = new Set<Integer>();
  for (Product__c p: familyDiscount) {
    if (p.Discount__c != null) {
      for (String discount: pf.Discount__c.split(',')) {
        // I guess this is a check you need?
        if (discount != '') {
          // turn the String into an Integer and add it to the set
          retVal.add(Integer.valueOf(discount));
        }
      }
    }
  }
  return new List<Integer>(retVal);
 }

[SalesForce] Getting the Selected Picklist Value Using Apex Trigger

You can use this logic:

if((o2.Type__c).equalsIgnoreCase('Type1'))
{
    o1.Picklist__c = 'Red';
}
else if((o2.Type__c).equalsIgnoreCase('Type2'))
{
    o1.Picklist__c = 'Blue';
}

Update Remove o1.Picklist__c = selectedPV; from the assignment as you are assigning Red or Blue depending on the if-else logic.
