正确的方式有一个DataGridView直观地反映变化的数据源 [英] Correct way to have a DataGridView visually reflect changes in its DataSource

问题描述

假设一个的DataGridView 有数据源属性设置为数据视图实例。

Say a DataGridView has its DataSource property set to a DataView instance.

DataGridView dgv;
DataTable dt;

// ... dt gets populated.

DataView dv = dt.DefaultView;

dgv.DataSource = dv;

// ... dt gets modified

// The DataGridView needs to update to show these changes visually
// What goes here?

我知道你可以设置 dgv.DataSource 到空，然后重新设置为 DV 。但是，这似乎是pretty的怪异。我敢肯定，有几个其他的方式了。但是，什么是正确的，正式的方式做到这一点？

I know you could set dgv.DataSource to null, then back to dv. But that seems pretty weird. I'm sure there are a couple of other ways, too. But what's the correct, official way to do this?
