Grid Popup Editor - Razor ForEach - List is null

[Jason]

Sample from RegistrationModel

1.public int Status      {get; set;}
2.public string Batteries    {get; set;}
3.public List<Batteries> BatteriesList     {get; set;}

 

Sample from Grid

1..Editable(editable => editable.Mode(GridEditMode.PopUp).TemplateName("EditRegistration"))

 

Sample from popup editor template

01.<h2>Batteries</h2>
02.@{
03.   if(Model.BatteriesList != null)
04.   {
05.    <ul>
06.        @foreach(var x in Model.BatteriesList)
07.        {
08.        <li>x.Selection</li>
09.        }
10.    </ul>
11.   }
12.}

 

• Model.BatteriesList is always null when the popup renders on-screen.
• I know the BatteriesList is filled with data.
• The other fields in my Editor Template show data.
• Not sure what I am missing here.

Can you assist?

Hello Jason,

The PopUp editor is initialized only once, when the Grid is created, using default model values. This is the reason for the current behavior - the default value of the List is null. The editor templates itself are bound via MVVM, which is why they display the correct model value when the PopUp is opened for each Grid item.
