Ravi,

 

      That because you have declared return type as Course__c instead of List<Course__c>.

public List<Course__C> getlst() {
      if (lst == null) {
        lst = [select Name from Course__c];
          }
        return lst;
       }
    }

               but iam facing 'System.NullPointerException: Attempt to de-reference a null object 

 

Class.Enquiry.getItems: line 70, column 1' at line for(Integer i=0; i < lst.size(); i++)

 

         thanks & regards

Ravi,

You can try something like this. Also I suspect your Course__c is not having data, double check that.

 <apex:outputLabel style="font-weight:Bold" value="Select a course :" />
     <apex:SelectList size="1" value="{!course}">
     <apex:selectOptions value="{!items}"/>
     </apex:SelectList>

    public String course {get; set;}
    public List<SelectOption> getItems(){
           
        List<SelectOption> options = new List<SelectOption>();
	List<Course__C> lst = [select Name from Course__c];
	if(1st != null){
		for(Integer i=0; i < lst.size(); i++){
		
		    options.add(new SelectOption(lst[i].Name,lst[i].Name));
		}
        }
        return options;
    }

You could save some lines of code and grief by doing this:

    public List<SelectOption> getItems()
    {      
        List<SelectOption> options = new List<SelectOption>();
	for(Course__c lst : [select Name from Course__c])
	{
	    options.add(new SelectOption(lst.Name,lst.Name));
        }
        return options;
    }
