TryCoding How to show PickList field as Radio Buttons on Visualforce Page
Hi all
i am having a problem and not able to get the solution even after a lot of serching
I have a picklist field with values 'yes' and 'No'
I want to show this field as radio buttons on my vf page. i.e. one radio button for yes and one for no. and at a time only one can be selected
can anybody help me how to do this...
i have tried using method on link below
http://blog.sforce.com/sforce/2008/12/using-the-metadata-api-to-retrieve-picklist-values.html
but this is giving error.. please suggest alternate solution..
thanks in advance..
hi pradeep
i think you did not understand my question...
yes,No is in my picklist field.that could be apple,mango,banana or whatever
At time of creting my UI (Visualforce Page) i know that i have a picklist field but i dont know the values in it.
i want to first retreive those values and then show them on my VF page as radio Buttons
Fortunately i have found solution to this. And i am posting that here.
Note that type__c is my picklist field.
Use following methos to get options for radio button on page
controller code:
public List<SelectOption> getTypes(){
Schema.sObjectType sobject_type = customObject__c.getSObjectType();
Schema.DescribeSObjectResult sobject_describe = sobject_type.getDescribe();
Map<String, Schema.SObjectField> field_map = sobject_describe.fields.getMap();
List<Schema.PicklistEntry> pick_list_values = field_map.get('type__c').getDescribe().getPickListValues();
List<selectOption> options = new List<selectOption>();
for (Schema.PicklistEntry a : pick_list_values) {
options.add(new selectOption(a.getLabel(), a.getValue()));
}
return options;
to use this on page:
<apex:selectRadio value="{!customObject__c.Type__c}">
<apex:selectoptions value="{!types}"></apex:selectoptions>
</apex:selectRadio>
I hope this will help solving someone else's problem.
cheers,
