从viewModel调用DataGrid.CancelEdit（）？ [英] call DataGrid.CancelEdit() from a viewModel?
问题描述
您好，
我正在使用MVVM处理Silverlight应用程序。
我正在尝试创建一个取消按钮在我看来，取消在数据网格中所做的所有更改（"BudgetDataGrid"）。
由于我正在使用MVVM，我不能在我的视图中编写cancel方法：
I'm working on a silverlight app, using the MVVM.
I'm trying to create a cancel-button in my view that cancel all changes made in a datagrid ("BudgetDataGrid").
Since I'm working with MVVM I can't just write the cancel method in my view:
BudgetDataGrid.CancelEdit（）
BudgetDataGrid.CancelEdit()
是否有某种方式来"触发"来自我的viewmodel的这个方法？
Is it some way to "trigger" this method from my viewmodel?

推荐答案
您好
根据您的解释，我的理解是您的取消按钮位于datagrid。
As per your explantion what i understand is that your Cancel button is outside the datagrid.
如果您的取消按钮位于Datagrid之外，那么您只需在ViewModel中创建命令并将其与您的按钮Command Property绑定。
If your cancel button is outside the Datagrid then you can simply create command in ViewModel and bind it with your button Command Property.
使用命令会附加方法，您可以在其中编写取消逻辑，或者您可以刷新数据网格绑定的集合。
With command there will be method attached in which you can write cancel logic or you can siply refresh the collection with which your datgrid is binded.
例如
In View <Button Command="{Binding CancelEditCommand}"/>
希望这可以帮助你，万一你不是exa告诉我，我可以更正你的代码。
