Hi guys

Any idea how to remove specific characters from the last iteration of a loop? We have a demo solution, where we want to remove the comma the from the lasty iteration of a checkbox list.

Hi Jens

Your caseItem.GetLoop("ItemPublisher:Item.SolutionType.Options") is a collection/enumeration, so you can do something like this:

var options = caseItem.GetLoop("ItemPublisher:Item.SolutionType.Options");
var totalOptionsCount = options.Count;
int optionsRendered = 0;
@foreach(var i in options)
{
    if(i.GetBoolean("ItemPublisher:Item.SolutionType.Option.IsSelected"))
    {
        var solutionType = i.GetString("ItemPublisher:Item.SolutionType.Option.Label");
        if(!(++optionsRendered == totalOptionsCount)){
            solutionType += ", ";
        }
        @solutionType
        }
}

Hi Nicolai, thank you for your answer.
It only works, when all the choices in the checkbox list is selected (6 total). Can i make it, so it will apply to only the ones selected (eg. 4 where that last does not have a comma)?

It cant figure it out  :|

Some LINQ should do that:

var totalOptionsCount = options.Count(option => option.GetBoolean("ItemPublisher:Item.SolutionType.Option.IsSelected") == true);
