我有一个以Datagrid为主要控件的工作代码。
我使用了Datagrid，因为很容易将数据绑定到它中。
我的代码需要将单元格移动到其他列中，所以我总是需要检查单击鼠标时我所在的单元格，以及何时释放它。
我目前的实施工作正如预期的那样。 但是，我检查行和单元格的方式是通过VIEW的代码隐藏。 我的项目负责人正在寻找一种替代方案，通过绑定完成此操作，因为他希望尽可能保持VIEW的代码隐藏。 我已尽力而为但我找不到能给我单元格列和行索引的属性。
请参阅下面的代码。 （省略了一些列，因为它会超出限制。）

我继续多次绑定datagridcell的列和datacontext属性作为我command的参数。我之前开始的一个选项，但由于时间限制而被搁置。我使用datacontext与我的viewmodel进行比较，而不是查找datagridrow的索引。诀窍。

实现您的要求的一般方法是为要替换的每个事件实施ICommand类型Attached Property。基本思路是......添加ICommand Attached Property和PropertyChangedCallback处理程序。在此处理程序中（当ICommand是绑定到此属性的数据时将调用此处理程序），将处理程序附加到要处理的事件。然后，当调用该事件时，只需执行ICommand实例。因此，您可以通过ICommand实例在视图模型中处理事件。以下是使用PreviewKeyDown事件的示例：
public static DependencyProperty OnEnterKeyDownProperty = DependencyProperty.RegisterAttached("OnEnterKeyDown", typeof(ICommand), typeof(TextBoxProperties), new UIPropertyMetadata(null, OnOnEnterKeyDownChanged));
public static ICommand GetOnEnterKeyDown(DependencyObject dependencyObject)
{
return (ICommand)dependencyObject.GetValue(OnEnterKeyDownProperty);
}
public static void SetOnEnterKeyDown(DependencyObject dependencyObject, ICommand value)
{
dependencyObject.SetValue(OnEnterKeyDownProperty, value);
}
public static void OnOnEnterKeyDownChanged(DependencyObject dependencyObject, DependencyPropertyChangedEventArgs e)
{
TextBox textBox = dependencyObject as TextBox;
if (e.OldValue == null && e.NewValue != null) textBox.PreviewKeyDown += TextBox_OnEnterKeyDown;
else if (e.OldValue != null && e.NewValue == null) textBox.PreviewKeyDown -= TextBox_OnEnterKeyDown;
}
private static void TextBox_OnEnterKeyDown(object sender, KeyEventArgs e)
{
if (e.Key == Key.Enter || e.Key == Key.Return)
{
TextBox textBox = sender as TextBox;
ICommand command = GetOnEnterKeyDown(textBox);
if (command != null && command.CanExecute(textBox)) command.Execute(textBox);
}
e.Handled = false;
}

替代方案是使用DataGrid已经提供给您的属性和/或定义一些其他附加属性来支持您完成工作。
我会尝试使用SelectedItem，SelectedValue，CurrentItem，CurrentCell等属性。
此外，如果无法使用上面的那些属性处理某个行为，我会创建一个附加属性，并为带有触发器的单元格使用样式来更改附加属性。绑定将所有更改从附加属性传输到ViewModel。
最后，您将只在ViewModel和View之间进行通信。

他们应该都是可绑定的
