    Get list of ID's

    Hi

    Trying to output the stored data, but I just get this

    System.Collections.Generic.Dictionary`2[System.String,System.Collections.Generic.IEnumerable`1[Umbraco.Core.Models.IPublishedContent]]

    I have seen this

    http://our.umbraco.org/projects/backoffice-extensions/widget-grid/bugs,-feedback-and-suggestions/43856-Umbraco-6-compatibility ;

    But that honestly does not help that much.

    How do I output a list of id's?

    Umbraco v 7.1.1

    Hi Mihael,

    In v7 it already comes back strongly typed as a dictionary, so you can access it like:

    var widgetGridContent = Model.Content.GetPropertyValue<IDictionary<string, IEnumerable<IPublishedContent>>>("widgets");

    From there, you can access the list of cell ids by

    widgetGridContent.Keys

    Or you can loop through a given cells contents like:

    foreach(var node in widgetGridContent["myCellId"]){
    <div class="wdieget">
        @node.Name
    </div>
}

    Hi Matt

    Thanks for the quick response.

    I'm getting this error now, so am I missing something?

    Compiler Error Message: CS0118: 'System.Collections.Generic.IDictionary<string,System.Collections.Generic.IEnumerable<Umbraco.Core.Models.IPublishedContent>>' is a 'type' but is used like a 'variable'

    Hi Mihael,

    Did you get a complete stack trace with your error? if so, can you share that aswell? Also, is your code exactly as above? or could you paste that in aswell, so I can check.

    Many thanks

    Matt

    Hi Matt

    I have this code in a Partial 

    @{var widgetGridContent = Model.Content.GetPropertyValue<IDictionary<string, IEnumerable<IPublishedContent>>("widgets"); }

    Which gives this error

    Aah... Theres an error in your code, theres a > missing, I think the text editor is messing it up.

    I now have this in a Partial

    @{

var widgetGridContent = Model.Content.GetPropertyValue<IDictionary<string, IEnumerable<IPublishedContent>>>("widgets");

}

foreach(var node in widgetGridContent["col-1"]){
           @node.Name
}

    Which works fine... 

    Thanks for your quick response...

    Ahh, yea, it's a pain keeping track of those :)

    Glad you were able to get it to work.

    PS I've updated my first answer with an extra '>'. Feel free to mark it as the answer if that all works for you now.

    Many thanks

    EDIT: This works too and is easier to read :-)

    foreach(var node in CurrentPage.widgets["col-1"]){
@Html.Partial(node.DocumentTypeAlias)
}

    Cool, hadn't tried it using dynamic node. Nice to know it works :)
