Shortcut to a List View in Salesforce

Here is a quick way to get to a list view without having to go looking for the tab or in the case that you don’t have a tab you can use this trick to get to a list view screen.

Here is one record of Account object is “Cadinal Inc”, and I want to go to the Account List View.

Once you’re on the record, trim off everything after the first three characters after the first slash.

My full URL is https://biswajeet-dev-ed.my.salesforce.com/0019000001EJPPH. I’m going to trim off the 9000001EJPPH and be left with https://biswajeet-dev-ed.my.salesforce.com/001. Once down run that link and you will go to the list view page for that object.

This will work with all standard and custom objects.

        acc = new Account();        
        typeOptions = new List<SelectOption>();
        
        //Use DescribeFieldResult object to retrieve status field.
        Schema.DescribeFieldResult typeFieldDescription = Account.Type.getDescribe();
        
        //For each picklist value, create a new select option
        for (Schema.PickListEntry pl:typeFieldDescription.getPicklistValues()){
            typeOptions.add(new SelectOption(pl.getValue(),pl.getLabel()));
            
            //Obtain and assign default value
            if (pl.defaultValue){
                acc.Type= pl.getValue();
            }  
        }
