I am using a ListBox with a DataTemplate. in each row of listbox data items, it will have 2 checkbox (IS_Like_Apple, IS_Like_Orange). Any idea on how to write the validation on checkbox in each row of items? (Must be minimum 1 checkbox is selected). Anyone have an idea for it? btw,i'm using mvvm.
this is my datatemplate code..

<DataTemplate x:Key="ListDataTemplate">
        <Grid TextBlock.FontSize="15" HorizontalAlignment="Left">
                <ColumnDefinition Width="Auto" SharedSizeGroup="ID"/>
                <ColumnDefinition Width="Auto" SharedSizeGroup="Name"/>
                <ColumnDefinition Width="Auto" SharedSizeGroup="Email"/>
                <ColumnDefinition Width="Auto" SharedSizeGroup="Like_Apple"/>
                <ColumnDefinition Width="Auto" SharedSizeGroup="Like_Orange"/>
            <TextBlock Grid.Column="0"  Text="{Binding  Path=WWID}"  />
            <TextBlock Grid.Column="1"  Text="{Binding  Path=Name}"  />
            <TextBlock Grid.Column="2"  Text="{Binding  Path=Email}" />
            <CheckBox Grid.Column="3"  IsChecked="{Binding Path=IS_Like_Apple}"/>
            <CheckBox Grid.Column="4"  IsChecked="{Binding Path=IS_Like_Orange}"/>

Hi, DataTemplate code is not enough!
Provide community with your MVVM model, and so on...

Fisrt thing that comes to my mind is:
- your model must to inherit IDataErrorInfo interface.
