Hi Rich W

The way Macro Parameters are 'read' it doesn't go via a Property Value Converter in the same way that reading a property value from a Document Type.

Therefore when you use

Model.MacroParameters["imageSlide"]

all you are able to get is the 'raw' ids of the images that have been picked in the multiple media picker.

But you can turn these into IPublishedContent by using the UmbracoHelper's 'Media' method which accepts an array of Ids and returns an IEnumerable of IPublishedContent.

So something like this might work for you:

//you'll get a csv of the ids
string pickedMediaCsv = Model.MacroParameters["imageSlide"].ToString();
// you can then turn them into an array of ids
string[] pickedMediaIds = String.Split(pickedMediaCsv, new char[]{','}, StringSplitOptions.RemoveEmptyEntries);
//now get the IPublishedContent representation
IEnumerable<IPublishedContent> mediaItems = Umbraco.Media(pickedMediaIds);

Hope that helps!

Marc

Marc,

Thank you. I modified my code as follows:

@inherits Umbraco.Web.Macros.PartialViewMacroPage
@using Umbraco.Web;
@using Umbraco.Web.Composing;
@using Clean.Core.Helpers;
@{
//you'll get a csv of the ids
string pickedMediaCsv = Model.MacroParameters["sliderImage"].ToString();
// you can then turn them into an array of ids
string[] pickedMediaIds = String.Split(pickedMediaCsv, new char[]{','}, StringSplitOptions.RemoveEmptyEntries);
//now get the IPublishedContent representation
IEnumerable<IPublishedContent> mediaItems = Umbraco.Media(pickedMediaIds);
}
@if (mediaItems != null)
{
<ul>
@foreach (var item in mediaItems) {
<li>Test</li>
}
</ul>
}
else{
<p>nope</p>
}

I'm currently getting the following error:

System.Web.HttpCompileException (0x80004005): C:\inetpub\wwwroot\UmbracoTemp\Views\MacroPartials\ImageSliderMacro.cshtml(10): error CS1503: Argument 1: cannot convert from 'string' to 'char'

Any more help would be greatly appreciated.

Marc,

Yes sir, that did the trick.

Thank you very much.
