    Access property after grouping

    Hi!

    I'm grouping a list of items by a date type property, which is working great. However, inside the initial group, I'm looking to add a header with the day of the group, I can't seem to access any properties of the group.

    Any ideas (code below)?

    Thanks!

    Amir

    @foreach(var itemGroup in selection.OrderBy("startDateAndTime").Skip((page -1)* pageSize).Take(pageSize).GroupBy("startDateAndTime.Day")) {
    
    <h1>@itemGroup.startDateAndTime.Day</h1> how do i get the date here!?
    
    foreach(var item in itemGroup) {
      @item.Name
    }
    

    }

    what is selection? is selection ipublishedcontent? then you can "itemgroup.GetpropertyValue< DateTime >("startdate").Day"

    You can do this I think :

    <h1>@itemGroup.Key</h1> how do i get the date here!?
    

    Haven't actually tried this code, but should work

    Yasir, selection is Umbraco.Web.Models.DynamicPublishedContentList

    itemGroup is Umbraco.Web.Dynamics.Grouping`2[System.Object,Umbraco.Web.Models.DynamicPublishedContent]

    Unfortunately both of the above suggestions return " 'object' does not contain a definition for..."

    Any ideas?

    Okay, changing selection to iPublishedContent by using Model.Content instead of CurrentPage allowed me to get @itemGroup.Key to work, but I still can't access any other properties? I can only get the group by day and not the year.

    Is there a way to access the properties of the group or even an item in it?

    Thanks!

    Have you tried itemgroup.GetpropertyValue("yourproperty")?

    why are you using groupby? can you not use this without groupby?

    I want to group items by day, add a heading for each day above the items, then iterate through the items. I want to heading to have day/month, hence the need to access more than just the key.

    ok!

    it can be achieve like this.

    @foreach(var itemGroup in selection.OrderBy("startDateAndTime").Skip((page -1)* pageSize).Take(pageSize)) { 
    var group = new DateTime();
    if(group!=itemGroup.GetPropertyValue<DateTime>("startDateAndTime")){
    <h1>@itemGroup.startDateAndTime.Day</h1> 
    }
    group = itemGroup.GetPropertyValue<DateTime>("startDateAndTime");
    @itemGroup.Name

    Hi Yasir, the grouping here just pulls the day for each item, not for the group.

    I'm trying to actually access properties of the group like:

    Group Date - group item - group item - group item

    Group 2 Date - group 2 item - group 2 item - group 2 item

    Is there a way maybe to just insert something before the first item in the group? -Amir

    Inserting something before the first item worked perfectly.

    Here's what I ended up with:

    @foreach(var itemGroup in selection.OrderBy("startDateAndTime").Skip((page -1)* pageSize).Take(pageSize).GroupBy("startDateAndTime.Day")) {
    foreach(var item in itemGroup) {
      if(item.IsFirst()) {
        <div class="grid-row-scheme-teal smallPadding marginBottom">
          @{
            string date = @item.GetPropertyValue("startDateAndTime").ToString();
          <h1>@umbraco.library.FormatDateTime(date, "MM/d ")</h1> 
          }
        </div>     
      }

    ok! have you solved it?

    Now i noticed one thing in my code

    if you just put the

    var group = new DateTime();
    

    Before loop then it should work as you want to.
