How to figure out if a DataGrid Row Has been Changed in MVVM?

Question

我想将WpfDatagrid行绑定到ViewModel中的布尔属性，以显示Row是否已更改。事实上，我有一个绑定到模型中的类的datagrid，并且在ViewModel中具有IsRowChanged属性，并且不要不知道如何将datagrid绑定到IsRowChanged？

Answer 1

    <DataGrid ItemsSource="{Binding Produts}" AutoGenerateColumns="False" >
        <DataGrid.Columns>
            <DataGridTemplateColumn IsReadOnly="True" >
                <DataGridTemplateColumn.CellTemplate>
                    <DataTemplate>
                        <CheckBox IsChecked="{Binding IsRowChanged}" />
                    </DataTemplate>
                </DataGridTemplateColumn.CellTemplate>
            </DataGridTemplateColumn>
        </DataGrid.Columns>
    </DataGrid>

If you use entity framework you can directly extend your entity partial class with this line

public bool IsRowChanged { get { return myEntity.EntityState == EntityState.Modified; } }
