Close popup and refresh parent window in Visualforce Page

Biswajeet   March 18, 2014   No Comments on Close popup and refresh parent window in Visualforce Page

Its a very common requirement to open a pop up by clicking a button . Once you are done with pop up, close the pop up and refresh the parent window so that user will be able to see the update on parent window at the same time.

Here is the sample code for it:

Command button in Visualforce Page:

<apex:commandbutton action="{!save}" id="button" oncomplete="javascript:CloseAndRefresh()" value="Update"/>

And here is the java script function:

<script language="JavaScript" type="text/javascript">
function CloseAndRefresh(){
window.opener.location.href="/{!$CurrentPage.parameters.id}";
window.top.close();

}
</script>

Note: I would suggest to check this setting Setup-> Personal Setup  ->  My Personal Information -> Personal Information
Here check for “Development Mode”. I have seen at various places and at community as well that if this check box is checked then popup would not close. Here, I would suggest to turn this checkbox off while you are testing this.

Display Multiselect Picklist as Checkboxes in Visualforce Page

Biswajeet   February 2, 2014   No Comments on Display Multiselect Picklist as Checkboxes in Visualforce Page

In below example I’ve created a custom multiselect picklist “Interests” on “Student” custom object. I’m displaying multiselect picklist to checkboxes in visualforce page.

Multiselect Picklist Field:

Controller:

public class SampleControllerExtn {
    public Student__c student {get;set;}
    
    public SampleControllerExtn(ApexPages.StandardController stdCtrl) {
        student = (Student__c)stdCtrl.getRecord();
    }
    
    public void saveStudent(){
        Upsert student;
    }
    
    //get the multi-select pick list values
    public List<SelectOption> getMSPicklist {
        get {
            List<SelectOption> options = new List<SelectOption>();
            for( Schema.PicklistEntry obj : Student__c.Interests__c.getDescribe().getPicklistValues()) {
                options.add(new SelectOption(obj.getValue(), obj.getLabel()));
            } 
            return options;
        }  
        set;
    }
    
    //get and set the multi-select pick list as checkboxes
    public String[] MSItems { 
        get {
            List<String> selected = new List<String>();
            List<SelectOption> options = this.getMSPicklist;
            for(SelectOption obj : options) {
                if (this.student.Interests__c !=null && this.student.Interests__c.contains(obj.getValue()))
                    selected.add(obj.getValue());
            }
            return selected;
        }public set {
            String selectedCheckBox = '';
            for(String s : value) {
                if (selectedCheckBox == '') 
                    selectedCheckBox += s;
                else selectedCheckBox += ';' + s;
            }
            student.Interests__c = selectedCheckBox;
        }
    } 
}

Visualforce Page:

<apex:page standardController="Student__c" extensions="SampleControllerExtn" tabStyle="Student__c">
    <apex:form>
        <apex:pageBlock>
            <apex:pageblockSection title="Student Details" columns="1" collapsible="false">
                <apex:inputfield value="{!student.name}"/>
                <apex:selectcheckboxes layout="pageDirection"  value="{!MSItems}" label="Interests">                   
                    <apex:selectoptions value="{!getMSPicklist}"/>      
                </apex:selectcheckboxes>
            </apex:pageblockSection>
            <apex:pageblockButtons>
                <apex:commandButton value="Save" action="{!saveStudent}"/>                
            </apex:pageblockButtons>
        </apex:pageBlock>
    </apex:form>
</apex:page>
