要执行您想要的操作，您需要正确构建数据。这意味着您需要为您的数据项创建一个类，并且在该类中，您需要拥有一个集合属性：

<DataGrid ItemsSource="{Binding ClassItems}" AutoGenerateColumns="False">
    <DataGrid.Columns>                                           
        <DataGridTextColumn Binding="{Binding StringPropertyFromClass}" Header="SR.NO." />
        <DataGridComboBoxColumn ItemsSource="{Binding CollectionPropertyFromClass}"
            SelectedItem="{Binding DataItemPropertyFromClass, Mode=Two-Way}" Header="Items" />
        ...
    </DataGrid.Columns>
</DataGrid>
