    checking for a boolean value

    i m trying to add a check for a boolean value in my code.

    this works ok

    var widgets = currentPage.Children.Where(x => x.DocumentTypeAlias == "widgetFolder").First().Children;

    but now that i need to put these widgets in 2 separate areas of the page i added a new property (is WidgetInTheBanner) which is a True/False field.....

    When i try

    var widgets = currentPage.Children.Where(x => x.DocumentTypeAlias == "widgetFolder" && !x.GetPropertyValue<bool>("isWidgetInTheBanner")).First().Children;

    i get an error  - Sequence contains no elements - so i presume this statement is incorrect format....

    Not really a format error but First is not getting anything, to make it more resilient, try this:

    var widgets = Model.Content.Children.FirstOrDefault(x => x.DocumentTypeAlias == "widgetFolder" && !x.GetPropertyValue<bool>("isWidgetInTheBanner"));
if (widgets != null)
{
    var somethingelse = widgets.Children;
}

    sorry I changed your currentPage to Model.Content to test

    var widgets = currentPage.Children.FirstOrDefault(x => x.DocumentTypeAlias == "widgetFolder" && !x.GetPropertyValue<bool>("isWidgetInTheBanner"));
if (widgets != null)
{
    var somethingelse = widgets.Children;
}
