Tech Enthu SelectOption
How do I set selectoption value dynamically based on query results?
I have a single select picklist on my VF page with list values 1,2,3,4,5 and I would like to use this selectlist within datatable to read/write records to database. I am able to write the data to table but when I want to read the data the selectoption is not showing the stored value automatically[still showing the list to select one option]. For sure I must be missing something silly so I would like to request for an example with both controller and VF page code.
Thank you
Hi
below sample code might help you
page :
<apex:selectList label="Product Family" value="{!selectedList}" size="1" id="selectListServiceType" multiselect="false" >
<apex:selectOptions value="{!PickListValues}"/>
</apex:selectList>
controller:
productList = all products queried and put into loop.
public PageReference getFamilyValues() {
productList7= new List<product2>();
valueList15 = new List<String>();
for(product2 p11:productList)
{
valueList15.add(p11.Family);
}
pickValues7 = new set<String>();
pickValues7.addAll(valueList15);
valueList16 = new List<String>();
valueList16.addAll(pickValues7);
valueList16.sort();
system.debug('..................'+valueList16);
PickListValues = new List<SelectOption>();
PickListValues.add(new SelectOption('--None--','--None--'));
if(valueList16.size()>0)
{
for(String s:valueList16) {
if(s!=null){
PickListValues.add(new SelectOption(s,s));
}
}
}
system.debug('.......................'+PickListValues);
Note: the above code is sample cde. i didn't declare any variables.
