I have a databound DataGridView. When a new row is added and the user presses Esc I want to delete the entire row. How can I do this?

推荐答案

如果要从DataGrid中删除行，您必须使用BindingSource而不是列表，否则，在执行此操作时您将收到异常。

If you want to remove rows from the DataGrid, you have to use a BindingSource instead of a list, otherwise you will get an exception when doing it.

尝试此操作：

public partial class YourForm : Form {

  private BindingSource _source = new BindingSource();

  public YourForm() {
    List<Model> list = _service.GetList();
    _source.DataSource = list;
    _grid.DataSource = _source;
  }
}

现在你可以玩数据源和网格将表现自己。每次更改后，别忘记调用_grid.Refresh（）。

Now you can play around with your datasource and the grid will behave itself. Don't forget to call _grid.Refresh() after each change.

干杯，
