Try having a look at this post

Have you also tried @product.relatedProducts.Count() > 2 ?  

Hi Fuji,

@product.relatedProducts.Count() does nothing. The script saves but I get an error on the web page just saying there was an error loading the macro.

The link you provided is for the Multi Node Tree Picker which is different to what I'm using, also it doesn't mention how you do any counting. :(

Hi John,

You should use the uComponents model deserialiser uComponents.Core.DataTypes.MultiUrlPicker.Dto.MultiUrlPickerState.Deserialize

Check out this pastebin for a great sample

Jeavon

You can see there is a Count() check in there already

Hi Jeavon, thanks for your reply.

I have tried implementing the code on the pastebin example but got this error message:

The type or namespace name 'DataTypes' does not exist in the namespace 'uComponents.Core' (are you missing an assembly reference?)

I have tried adding the below as a namespace but got the same error.

using uComponents.Core.DataTypes.UrlPicker;

Any ideas?

The using statement in my project is:

using uComponents.DataTypes.MultiUrlPicker.Dto

Maybe there have been different versions, but probably this is the one you need.  With that in place you should be able to reference:

MultiUrlPickerState.Deserialize()

Andy

Hi John,

What version of uComponents do you have?

Jeavon

@Andy is right, it did change between versions somewhere, I think v5

I'm using uComponents v6.0.0

OK, so I have edited my script and the on save error has gone but it still says Error loading macro on the page.

Here is the first few lines of my code.

@using umbraco.MacroEngines
using uComponents.DataTypes.MultiUrlPicker.Dto
@inherits umbraco.MacroEngines.DynamicNodeContext


@{
    uComponents.DataTypes.MultiUrlPicker.Dto.MultiUrlPickerState links = null;  
    var product = Model.AncestorOrSelf("Product");
    if(product.HasValue("relatedProducts"))
    {   
        @* Check if the current product has any related products at all*@
        links = uComponents.DataTypes.MultiUrlPicker.Dto.MultiUrlPickerState.Deserialize(Model.relatedProducts);
        if (links != null && links.Items.Count() > 0)
        { ...

I really have no clue where it doesn't work.

Thanks again

The only issue I see is the missing @ before the using

@using umbraco.MacroEngines
@using uComponents.DataTypes.MultiUrlPicker.Dto
@inherits umbraco.MacroEngines.DynamicNodeContext

Have you got visual studio or another IDE that can give you intellisense?

Its gonna be hard trying to write razor from Umbraco backoffice.

yea the @ is missing.

If you paste the full mark up i will put in in Visual Studio and see what resharper makes of it :).

Charlie

Thanks for your comments, all.

I have added the missing @ to no avail.

I have Visual Web Developer 2010 installed and have been using that in some cases to write the scripts, but it doesn't show any errors, and the whole site builds without errors.

Here is my full script.

@using umbraco.MacroEngines
@using uComponents.DataTypes.MultiUrlPicker.Dto
@inherits umbraco.MacroEngines.DynamicNodeContext


@{
    uComponents.DataTypes.MultiUrlPicker.Dto.MultiUrlPickerState links = null;  
    var product = Model.AncestorOrSelf("Product");
    if(product.HasValue("relatedProducts"))
    {   
        @* Check if the current product has any related products at all*@
        links = uComponents.DataTypes.MultiUrlPicker.Dto.MultiUrlPickerState.Deserialize(Model.relatedProducts);
        if (links != null && links.Items.Count() > 0)
        {       
                <div class="width1680 popularProducts">
                <div class="width960">
                <h1 class="centerText">RELATED PRODUCTS</h1>
                @foreach (var urlPicker in Model.AncestorOrSelf("Product").relatedProducts.Items)
                {

                    if(urlPicker != null)
                    {
                        var linkTarget = (urlPicker.NewWindow) ? "target=\"_blank\"" : String.Empty;
                        var nodeId = urlPicker.NodeId;
                        var image = Library.NodeById(nodeId);
                        <div class="floatProducts">
                            <div class="sqrProductsImage">
                                <a href="@urlPicker.Url" @Html.Raw(linkTarget)>
                                    <img src="@image.Media("mainImage","umbracoFile")" />
                                </a>
                            </div>
                            <a href="@urlPicker.Url">           
                                <div class="overlay"></div>
                                <div class="ic_caption">
                                <h2 class="centerText">@image.Name</h2> 
                                </div>
                            </a>    
                        </div>

                    }
                }
                <div class="clearLeft"></div>
                </div>
                </div>
        }
    }

}

Does anyone have any thoughts on this at all please?

Is the MultiUrlPickerState object returning an Enum?

so links will = a collection of MultiUrlPickerStates

so you should be able to do links.count, which will give the total number of MultiUrlPickerState object in the collection. :).
