看看 Computed Columns [ ^ ]



或单元格事件 [ ^ ]



帮助你。



如果你真的需要按钮更新，请尝试调用Datagridview2.Refresh和/或Aftervalidate循环结束。

See if Computed Columns[^]

or Cell events [^]

help you.

If you really need on button update, try calling Datagridview2.Refresh and/or Invalidate after the loop finishes.

Howdy All，

在for循环后尝试这个：



Dim cm作为CurrencyManager = Direct Cast（datqaGridView2.BindingContext（dataGridView2.DataSource），_ CurrencyManager）

cm.Refresh（）



regs， b $ b

ron O。

Howdy All,
Try this after the for loop:

Dim cm As CurrencyManager = DirectCast(datqaGridView2.BindingContext(dataGridView2.DataSource), _ CurrencyManager)
cm.Refresh()

regs,

ron O.
