大家好，
实际上，主题说明问题。详情为何;
我有一个Windows窗体DataGridView从一个SQL表中的数据。我插入DataGridViewCheckBoxColumn的复选框。我需要检查一个或多个复选框（行）更新选定行。有一个列，其中包括的DateTime。我尝试过这么多的代码，但都失败了，我猜是因为DateTime列
我会很高兴，如果你可以给一些例子，如代码。
提前感谢，
For each row as DataGridViewRow in Datagridview1.Rows
'Assuming first column has the checkboxes
If row.Cells(0).Value = True Then
'Carry out update and make sure your DateTime is properly formatted
cmdUpdate = "UPDATE TABLE ... SET ... WHERE ..."
End If
Next
