Overwrite record after Search -MVVM WPF

I have a View ConfigRole which contains DataGrid with two Columns: View and IsEnabled(CheckBox), and a Search area.

and the Button Save it works correctly, I make all views which I want IsEnabled and I save it : for exemple:

And when I use the search box, I have the correct result for all the views I search on it,for exemple I write 'Customer' in search box ,I have all the views with the key 'Customer':

My problem is when I make Save Button after Search ,all the CheckBox (IsEnabled in the first View will be FALSE !! just the Views I make it Enabled in the Search view are Save !

XAML ConfigRole:

<TextBox x:Name="textBox" Text="{Binding ViewName, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged,
NotifyOnValidationError=True ,TargetNullValue=''}" />
<DataGrid x:Name="dataGrid" SelectedItem="{Binding SelectedView}" ItemsSource="{Binding ViewList}"
CanUserAddRows="False" AlternationCount="2" AlternatingRowBackground="Blue" AutoGenerateColumns="False" >
<DataGrid.Columns>
<DataGridTextColumn Header="View" Binding="{Binding ViewCode}" IsReadOnly="True" />
<DataGridTemplateColumn Header="Is Enabled" Width="Auto">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<CheckBox IsChecked="{Binding IsEnabled, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"/>
DataTemplate>
DataGridTemplateColumn.CellTemplate>
DataGridTemplateColumn>
DataGrid.Columns>
DataGrid>
lt;Button Command="{Binding SaveRole}" Visibility="{Binding Path=ShowSaveButton, Converter={StaticResource BoolToVis}}" CommandParameter="{Binding ElementName=ConfigureRole}"/>
Grid>

ConfigRoleViewModel:

private ObservableCollection _viewList;
private MiniTasServicesClient WCFclient = new MiniTasServicesClient();
public int test;
public ConfigRoleModel(int RoleId,ObservableCollection roleList)
{
test = RoleId;
_viewList = new ObservableCollection(WCFclient.getViewRoleMapsByRole(RoleId));
saveRole = new RelayCommand(configRole);
}
private RelayCommand saveRole;
public RelayCommand SaveRole
{
get { return saveRole; }
}
//all list of Views
public ObservableCollection ViewList
{
get { return _viewList; }
set
{
_viewList = value;
OnPropertyChanged("ViewList");
}
}
//the Function of the Button Save
private void configRole(Window window)
{
List listViewRoleMap = new List();
foreach (ViewRoleMapClass view in ViewList)
{
if (view.IsEnabled) listViewRoleMap.Add(view);
}
int resultUpdate = WCFclient.updateViewRoleMap(listViewRoleMap, test);
if (resultUpdate == 0)
{
string sCaption = "Save notification";
string sInformation = "Save operation is performed successfully";
MessageBoxButton btnMessageBox = MessageBoxButton.OK;
MessageBoxImage icnMessageBox = MessageBoxImage.Information;
MessageBoxResult rsltMessageBox = MessageBox.Show(sInformation, sCaption, btnMessageBox, icnMessageBox);
}
_refreshList();
}
//Search
private string _viewName;
public string ViewName
{
get { return _viewName; }
set
{
_viewName = value;
OnPropertyChanged("ViewName");
_viewList = searchByCriteria(ViewName);
OnPropertyChanged("ViewList");
}
}
private ObservableCollection searchByCriteria(string _viewName)
{
List resultSearch=new List();
_viewList = new ObservableCollection(WCFclient.getViewRoleMapsByRole(test));
if (_viewName != null)
{
resultSearch = _viewList.Where(c => c.ViewCode.ToLower().Contains(_viewName.ToLower())).ToList();
}
return new ObservableCollection(resultSearch);
}

How can I fix it?

Thanks,
