Looping through models content in Razor

Question

I want to loop through each item in my model in my razor view but I want to group all items together. I then want to loop through each group. Imagine I have a table:

<

Yes, this is easy to do using the Linq GroupBy. I'd suggest changing your view to use @model IEnumerable>, which you'd populate like this:

var groupModel = MyModelCollection.GroupBy(item => item.GroupNo).ToArray();
return View(groupModel);

Then, simply iterate through the group as you wrote, except using group.Key instead of group.GroupNo to retrieve IGrouping's key:

@foreach (var group in Model) {
    

        
Group No is @group.Key
        @foreach (var item in group) {
            
GroupName: @item.GroupName
        }
    
}
