    Razor foreach checking value instantly

    Templates, (partial) views and macros
    Umbraco 7

    Hi,

    Is there a chance to check a value within a foreach at the same time? I would like to filter by value and show randomly only one.

    Hi Levente

    What do you have in mind?

    Something like

    @foreach (item in Model.News){

    if(item.Headline.HasValue){
          //Do something
     }
}

    Or are you thinking more like

    @foreach(item in Model.News.Where("Condition")){
      //Do something
}

    Perhaps you can benefit from the Razor cheetsheet here https://our.umbraco.org/projects/developer-tools/umbraco-v6-mvc-razor-cheatsheets/ - It's made for Umbraco 6 but should be relevant for v7 as well - Be aware that the one I linked to is for strongly typed razor - If you're using dynamics then you should have a look at this cheatsheet instead https://our.umbraco.org/projects/developer-tools/razor-dynamicnode-cheat-sheet

    Look for the "Filtering and ordering extensions".

    Hope this helps.

    /Jan

    Definitely the second what I need. Thank you for the links, but I can't deal with it, this is what I have at the moment:

    var projectImagesList = CurrentPage.projectImages.ToString().Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries);
var projectImagesCollection = Umbraco.Media(projectImagesList);

foreach (var projectImage in projectImagesCollection.Where("Visible").Random(1))
{
    if (imageType == "medium-landscape")
    {
        do something
    }
}

    And I need to check imageType == "medium-landscape" outside.
