Can't get Properties of a Specific Child Page

Question

I just started using umbraco 4 days ago and I'm stuck with this problem.

I have a page named "About Us" that is a child under "Home" and I need to get some of its properties in the "Home" Page.

I created a partial view macro to do this but I get the error loading partial view script instead.

Below is my code:

@{ var selection = CurrentPage.Children.Where(x => x.Name == "aboutus"); }

@if (selection.Any())
{
    <ul>
        @foreach (var item in selection)
        {
            <div class="sc-inner">
                <h4>
                   @item.PageTitle</h4>
                <p>
                   @Umbraco.Truncate(@item.mainAboutDescription, 100)</p>
                <a class="btn btn-danger" href="@item.Url">Read More...</a>
            </div>
            break;
        }
    </ul>
}

Can someone please tell me what I'm doing wrong?

Thanks in advance.

Edits: The error on the website I got is below;

Error loading Partial View script (file: ~/Views/MacroPartials/homePage_aboutUsSection.cshtml)

Answer 1

Assuming the partial is inheriting UmbracoTemplatePage the CurrentPage property is a dynamic, you cannot use lambda expressions as an argument to a dynamically dispatched operation.

If you wish to use Linq to query the content use Model.Content rather than CurrentPage which is an IPublishedContent e.g.

@{ var selection = Model.Content.Children.Where(x => x.Name == "aboutus"); }

Note: the Name property will return the documents Name as entered in the CMS most likely 'About Us' instead of 'aboutus'

Using the about will return an IEnumerable<IPublishedContent> so you will need to use the GetPropertyValue method rather than accessing the content dynamically:

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage

@{ var selection = Model.Content.Children.Where(x => x.Name == "aboutus"); }

@if (selection.Any())
{
    <ul>
        @foreach (var item in selection)
        {
            <li class="sc-inner">
                <h4>
                    @item.GetPropertyValue("pageTitle")
                </h4>
                <p>
                    @Umbraco.Truncate(@item.GetPropertyValue<string>("mainAboutDescription"), 100)
                </p>
                <a class="btn btn-danger" href="@item.Url">Read More...</a>
            </li>
            break;
        }
    </ul>
}
