    How can I use lambda clause?

    Hi guys,

    I have a nuPicker with a dropdown list of builders, and its works fine. enter image description here

    However, I want to display all the Siblings with the same builder homes

    I've try

    @foreach (var builderId in CurrentPage.builder.PickedKeys)
{
    <h4>@builderId</h4> //Get the selected builder ID

    foreach (var relatedItems in Model.Content.Siblings().Where(x => x.Id != Model.Content.Id && x => x.builderId == builderId).RandomOrder().Take(3))
    {
             // do some stuff...
    }

    }

    How can I the lambda if they are the same in builderId?

    I'm using Umbraco v7.

    Thanks in advance,

    Jin

    Hi Jin,

    Are you using Models Builder? If so I think your builderIdwill be BuilderId. If not they you need to use GetPropertyValue so your where clause would become:

    Model.Content.Siblings().Where(x => x.Id != Model.Content.Id && x.GetPropertyValue("builderId") != null && x.GetPropertyValue<string>("builderId") == builderId)

    Just to note as well, that you should only need to do x => once in your where clause, at the start.

    Hi Ben,

    Thank you for response!

    But don't have display, the foreach statement is not TRUE.

    Or is there any other ways to implement related posts with the same in builderId?

    I have a limited knowledge in Umbraco.

    Regards,

    Jin

    Hi Jin,

    Can you post your document types please (probably the one you're on now and the one with the picker)?

    Hi Ben,

    Thanks for your fast response, I'm really new in Umbraco.

    Thanks Jin,

    Look like your property alias id should be builder, not builderId. Try the following:

    Model.Content.Siblings().Where(x => x.Id != Model.Content.Id && x.GetPropertyValue("builder") != null && x.GetPropertyValue<string>("builder") == builderId)

    Hi Ben,

    No display again! Maybe the output of

    .GetPropertyValue<string>("builder")

    is JSON

    [ { "key": "3124", "label": "One Homes" } ]

    And theforeach statement is ...GetPropertyValue<string>("builder") == builderId and the builderId is an INT ?

    Regards,

    Jin

    Hi Ben,

    What I've done now is;

    Successfully getting the nuPicker ID in each homes inside foreach loop.

    @ {
     // Get the selected nuPicker ID
     var BuilderId = CurrentPage.builder.PickedKeys[0];

     foreach (var relatedItems in Umbraco.Content(1099).Children)
        {
            // Get the nuPicker ID in each homes
            var relatedItemsid = relatedItems.GetPropertyValue("builder").PickedKeys[0];
        }
}

    My Problem now is, I want to use the relatedItemsid in Where() or the lambda clause.

    Any help for this.

    Thanks in advance,

    Jin
