对于虚拟对象,DataView对象RowStateFilter与RowFilter对象 [英] DataView objects RowStateFilter vs RowFilter for dummies
问题描述
有人能用简单的
条款解释RowStateFilter
和DataView对象的RowFilter属性之间的区别吗?
I我正在通过Transcender练习考试,当我认为我理解差异时,我会错过
问题。两周前没有通过306考试和
不想再重复一次<<得分680,需要700: -
(> ;>
顺便说一句,如果你正在参加考试,你需要在b / b
调试中学习。如果你在家里有一个尖叫的孩子,他会赢得' 't
让你学习......我完全理解:-)

Can anyone explain the difference between RowStateFilter
and RowFilter properties of the DataView objects in simple
terms?
I am going through a Transcender practice exam and just
when I think I understand the difference I miss the
question. Didn''t pass the 306 exam two weeks ago and
don''t want to repeat that again <<scored 680, needed 700 :-
( >>
BTW of if you are taking the exam study your butt off on
debug. And if you have a screaming baby at home who won''t
let you study...I totally understand :-)

嗨再次Roy,
RowFilter属性允许您过滤行的< contents>。
因此您可以获得具有的行,例如,给定的
列中的给定值。过滤器将完全取决于您拥有的列以及它们持有的
。
RowStateFilter属性允许您过滤
行的< state>。因此您可以获得已添加,删除,mofified等的行
仅根据DataViewRowState枚举。
Hi again Roy,
The RowFilter property allows you to filter on the <contents> of the Rows.
So you can obtain the Rows that have, for example, a given value in a given
column. The filter will depend entirely on what columns you have and on what
they hold.
The RowStateFilter property allows you to filter on the <state> of the
Rows. So you can obtain the Rows that have been added, deleted, mofified, etc
according only to the DataViewRowState Enumeration.
你好再次Roy,
RowFilter属性允许你过滤掉< ;
Rows的内容>所以你可以获得在给定列的
中具有给定值的行。过滤器是包含一个字符串的字符串。表达,并将取决于什么柱子上的
你有他们持有什么。
RowStateFilter属性允许你过滤< state>
行。所以你可以根据DataViewRowState枚举获得已经添加,删除,修改等的行,

Hi again Roy,

given column. The filter is a string containing an expression, and will depend
on what columns you have and on what they hold.
The RowStateFilter property allows you to filter on the <state> of the
Rows. So you can obtain the Rows that have been added, deleted, modified, etc,
according only to the DataViewRowState Enumeration.
