Hi,
I have a problem merging two selection into one variable. I have tried using concat but I cannot figure out the correct syntax, or perhaps I should use another approach?
Any help would be greatly appreciated :-)
// Selection 1
var Coll1= homePage1.Descendants("Ledig").Where("Fastid = @0", @Lokal.Fastid).FirstOrDefault();
var image1 = Coll1.Bilds.FirstOrDefault();
// Selection 2
var Coll2= homePage1.Descendants("Ledig2").Where("FastighetsId = @0", @Lokal.Fastid).FirstOrDefault();
var image2 = Coll2.Bilds.FirstOrDefault();
// MERGE SELECTIONS
var image12= image1.Concat(image2); //This does not work!
//Code generating output data
@{if(image12!= null)
{
// do something
<a href="@image12.bildfil" data-lightbox="[email protected]@Lokal.Objektsid" data-title="@image12.Bildrubrik">
<!-- Use ImageGen querystring to automatically generate a thumbnail & setup fallback image -->
<img style="vertical-align: middle;" src="/[email protected]&height=120&width=200&crop=resize&align=center&altImage=/Media/no-image.png" alt="@image12.Name"/>
</a>
}
}
</div>
}
You are trying to merge two individual elements together, which fundamentally isn't possible because how would the system know which properties to replace etc.
What you can do is this:
var myCombinedList = new List<IPublishedContent>();
myCombinedList.Add(image1);
myCombinedList.Add(image2);
Then you can do the following:
foreach(image in myCombinedList)
{
<div>@image.Name</div>
}
This would output the name of both of the images one after the other.

Hi Martin
Can you show all code?
Alex
Hi,
I have added the code that generates html code showing the images and text. Note that my code works fine if I only use either 'image1' or 'image2'.
For example
var image12= image1;will make the code work fine (but of course I then miss the data fromimage2).Hi Martin,

Does that help?

Ok thanks you, I will try this. I let you know if it works.
It didn't work well, Trying to use
myCombinedList.Add(image1);throws server error.One idea I have is to combine
Coll1.BildsandColl2.Bildsbefore selectingFirstOrDefault().I should point out that Bild is a doc type and Bilds will thus contain the elements found all pages based on doc type Bild ( i.e. .[DocTypeName]s ) .
Do you think that would make it easier?
Martin, are you sure that these lines are working?
What is "Bilds"?
Hi,
Yes it works fine. 'Bild' is a document type. I will try Nik's suggestion och hope it works.
is working on a reply...
