Hi,

I have written this code here /Views/Partials/undervisningLeft.cshtml

why is getting error.

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage


var node = Model;

    foreach(var text in node.Children) {
        <div class="module">
            <h2>@text.title</h2>
            <p>@text.bodyText</p>
        </div>
        <div style="clear: both;"></div>
    }

now i got error

The first issue seems to be var node = Model which should be:

var node = Model.Content;

Additionally, as you are not dealing with strongly typed content, you cannot directly access the property values using the syntax you are using. Each item in node.Children is an IPublishedContent item which has no idea what title and bodyText are. You would have to use GetPropertyValue("myPropertyName") to get the property values you require.

This should work:

foreach(var text in node.Children) 
{
    <div class="module">
        <h2>@text.GetPropertyValue("title")</h2>
        <p>@text.GetPropertyValue("bodyText")</p>
    </div>
    <div style="clear: both;"></div>
}

Hi John,

use this:

var node = Model.Content;

instead of

var node = Model;

Hope this helps!

Ok , I have written like that,

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage

var node = Model.Content;

 foreach(var text in node.Children)  {
    <div class="module">
        <h2>@text.GetPropertyValue("title")</h2>
        <p>@text.GetPropertyValue("bodyText")</p>
    </div>
    <div style="clear: both;"></div>

But it is getting same error.

Are you using Visual Studio? Can you debug?

Maybe try tidying up a bit first. Above snippet is missing closing brace on foreach as well:

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage
@{
    var node = Model.Content;
}

@foreach (var text in node.Children)
{
    <div class="module">
        <h2>@text.GetPropertyValue("title")</h2>
        <p>@text.GetPropertyValue("bodyText")</p>
    </div>
    <div style="clear: both;"></div>
}

Hi Jhon,

if you really want to learn Umbraco then have a look at the documentation which is getting better and better these days:

https://our.umbraco.org/documentation/

Also another good source is https://umbraco.tv/ which contains lot of videos of how to do things in Umbraco.

Have a nice learning experience with Umbraco and don't forget, if you have questions don't hesitate to ask them on the forum!

Hope this helps!

Hi,

It works fine below coding.

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage @{ var node = Model.Content; }

@foreach (var text in node.Children)

{

@text.GetPropertyValue("titleBox")

@text.GetPropertyValue("linksText")

</div>

}

Using the same output , i have written in another way , Why is it not working?

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage

var boxes = Model.Children.Where("NodeTypeAlias == \"undervisningBox\"");



    foreach (var box in boxes) {
        <div class="box">
            <h4>@box.GetPropertyValue("titleBox")</h4>
            @box.GetPropertyValue("linksText")
        </div>
    }

I am getting error.

Hi Jhon,

try the following:

var boxes = Model.Children.Where(x => x.DocumentTypeAlias == "undervisningBox");

Hope this helps!

Hi Jhon,

can you show us the complete code snippet of your partial view because now you are missing braces.

Should be something like below:

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage

@{
    var boxes = Model.Content.Children.Where(x => x.DocumentTypeAlias == "undervisningBox");
}

@foreach (var box in boxes)
{
    <div class="box">
        <h4>@box.GetPropertyValue("titleBox")</h4>
        @box.GetPropertyValue("linksText")
    </div>
}

Thanks

Hi Jhon,

had a typo it has to be:

var boxes = Model.Content.Children.Where(x => x.DocumentTypeAlias == "undervisningBox");

Forgot the .Content part ( writing without compiler ).

Hope this helps!

Hi Jhon,

The Library is not known, which version of Umbraco are you using?

Please have a look at these docs about getting the image from a Media Picker:

https://our.umbraco.org/documentation/Getting-Started/Backoffice/Property-Editors/Built-in-Property-Editors/Media-Picker2

Hope this helps.

<a href="@projekt.Url">
<div class="card__image border-tlr-radius">
@{

var typedMultiMediaPicker = Model.Content.GetPropertyValue<IEnumerable<IPublishedContent>>("image");

    <img src="@projekt.GetPropertyValue("image")" style="width:200px"/>

}

                <article class="card__article">
                    <h2><a href="@projekt.Url">@projekt.GetPropertyValue("titel")</a></h2>

Hi Jhon,

look at the example in the docs: https://our.umbraco.org/documentation/Getting-Started/Backoffice/Property-Editors/Built-in-Property-Editors/Media-Picker2#typed-example-multiple-enabled

You can see that for the source of the image you just can use:

 <img src="@typedMultiMediaPicker.Url" style="width:200px" />

Hope this helps!

Hi Jhon,

that's because you enabled the Multi selection of the picker. So your typedMultiMediaPicker contains a list of images.

You need to loop over these images using a foreach, if you only want one image then you can change the property to disable multi selection and then change your code to:

var typedMultiMediaPicker = Model.Content.GetPropertyValue<IPublishedContent>("image");

Now it contains only one image.

Hope this helps!

Hi Jhon,

could you add a null check to see if you really have an image:

if (typedMediaPickerSingle != null)

If i add like that ,

@{ var typedMultiMediaPicker = Model.Content.GetPropertyValue

<img src="@typedMultiMediaPicker.Url" style="width:200px" />
 }

}

Is not displaying image , Title and teaser is displaying . see output.

What is the alias of your Billede property? Because you set image as the property Alias for taking the image. Shouldn't it be:

var typedMultiMediaPicker = Model.Content.GetPropertyValue<IPublishedContent>("billede");
