如何更改基于新的单元格的值是否>或其中的DataGridView细胞前景色;比现有/旧单元格的值？有没有这通过改变目前的新前值的事件，这样我就可以比较它们？

How to change DataGridView cell ForeColor based on whether new cell value is > or < than current/old cell value? Is there an event which passes the new value before the current is changed, so I can compare them?

的数据从底层源更新，并且可以通过BindingSource的约束。

The data is updated from underlying source, and may be bound by BindingSource.

我遇到了类似的问题。我使用 CellValidating 事件，而不是解决这样的：

I ran into a similar issue. I tackled this by using the CellValidating event instead:

void dgv_CellValidating(object sender, DataGridViewCellValidatingEventArgs e)
{
    var oldValue = dgv[e.ColumnIndex, e.RowIndex].Value;
    var newValue = e.FormattedValue;
}

当然，我只需要访问旧的价值，我不需要进行任何格式。我敢肯定，你可以将通过此事件处理程序的格式，虽然。

Admittedly, I just needed access to the old value, I didn't need to perform any formatting. I'm sure you can apply formatting through this event handler, though.
