How to open a new Tab using PageReference in apex class?

Biswajeet   August 17, 2016   5 Comments on How to open a new Tab using PageReference in apex class?

We can use apex:commandLink to redirect a visualforce page in a new Tab URL using PageReference in apex class.

Sample Code:

VF Page:

<apex:page controller="SampleleRedirect">
	<apex:form >
		<apex:pageblock >
			<apex:commandlink action="{!redirect}" target="_blank">
				<apex:commandButton value="Open in New Tab"/>
			</apex:commandLink>
		</apex:pageblock>
	</apex:form>
</apex:page>

Apex Controller:

public class SampleleRedirect {   

	public SampleleRedirect() {
	
	}

	public pageReference redirect() {
		PageReference pageRef = new PageReference('http://www.biswajeetsamal.com');
		pageRef.setRedirect(true);
		return pageRef;
	}            
}

Apex Class:

public class DemoController {
    
    Public List<Account> accList {get;set;}
    public Integer rowIndex {get;set;}
    
    public DemoController(){
        accList = new list<Account>();
        accList.add(new Account());
    }
    
    public void addRow(){
        accList.add(new Account());
    }
    
    public pagereference saveAccount(){
        Insert accList;
        return null;
    }
    
    public PageReference deleteRow(){
        rowIndex = Integer.valueOf(ApexPages.currentPage().getParameters().get('rowIndex'));
        accList.remove(rowIndex);
        return null;
    }
}

Visualforce Page:

<apex:page controller="DemoController">
    <apex:form id="fm">

                    <apex:inputField value="{!ac.Industry}"/>
                </apex:column>
                <apex:column headerValue="Action" >
                    <apex:commandButton value="Delete" action="{!deleteRow}" reRender="pb">

                </apex:column>
            </apex:pageBlockTable>
            <apex:pageBlockButtons >
                <apex:commandButton value="Add Row" action="{!addRow}"/>
                <apex:commandButton value="Save Accounts" action="{!saveAccount}"/>
            </apex:pageBlockButtons>
        </apex:pageBlock>
    </apex:form>
</apex:page>

Related list Button Edit/Delete/View is not working in VF Page on Service Cloud Console

Biswajeet   May 26, 2016   No Comments on Related list Button Edit/Delete/View is not working in VF Page on Service Cloud Console

If showHeader="false" in VF Page, the related list Button Edit/Delete/View won’t work on Service Cloud Console.
When showHeader is set to false, some important JS files needed for the service cloud console to function properly will not be loaded, and hence you may see some issues. It is recommended to leave showHeader as true while using in the service cloud console.
