Hi,
I have a list of checkboxes, but when I click to check one all checkboxes is checked.
This is when using Ajax binding:
<input id="SelectedRoles_Administrators" type="checkbox" value="Administrators" name="SelectedRoles" data-bind="checked:SelectedRoles">
<label for="SelectedRoles_Administrators">Administratör</label>
   
<input id="SelectedRoles_SuperAdministrators" type="checkbox" value="SuperAdministrators" name="SelectedRoles" data-bind="checked:SelectedRoles">
<label for="SelectedRoles_SuperAdministrators">Superadministratör</label>
But when using Server binding it works as it should:
<input id="SelectedRoles_Administrators" type="checkbox" value="Administrators" name="SelectedRoles">
<label for="SelectedRoles_Administrators">Administratör</label>
    
<input id="SelectedRoles_SuperAdministrators" type="checkbox" value="SuperAdministrators" name="SelectedRoles">
<label for="SelectedRoles_SuperAdministrators">Superadministratör</label>
Is it some sort of a bug or is the code wrong typed in some way?
Original code:
@foreach (var role in roles)
 {
    <input type="checkbox" name="SelectedRoles" id="SelectedRoles_@(role.Enum)" value="@role.Enum"  /><label for="SelectedRoles_@(role.Enum)">@role.Text</label>
}

Hello Mattias,

What  type is the "SelectedRoles" field in your model? When using a list of checkboxes it should be a collection. If it is not a collection then you could use radio buttons. Please check this documentation topic for information on checked binding.

Hi,
It's look like:
public int[] SelectedRoles { get; set; }
but I have also tested with:
public IList<RoleTypes> SelectedRoles { get; set; }

Hello Mattias,

If the field is a collection then the problem could be cause the property not being initialized. Please check if initializing the collection in the ViewModel constructor resolves the problem:

public class MyViewModel
{
    public MyViewModel()
    {
        this.SelectedRoles = new List<RoleTypes>();
    }
