asp.net 框架页刷新时如何保留或返回之前的页面
有这样的需求，需要刷新整个框架页的时候，但不希望子页返回默认路径，那就用这个方法吧。
global里加入如下代码：
1
protected
void
Application_BeginRequest(
object
sender, EventArgs e)
2
{
3
Application[
“
urlold
“
]
=
Application[
“
url
“
];
4
if
(Request.RawUrl.ToUpper().Contains(
“
.ASPX
“
))
5
{
6
if
(
!
Request.RawUrl.ToUpper().Contains(
“
DEFAULT.ASPX
“
))
7
Application[
“
url
“
]
=
Request.RawUrl;
8
}
9
10
}
11
protected
void
Application_BeginRequest(
object
sender, EventArgs e)
2
{
3
Application[
“
urlold
“
]
=
Application[
“
url
“
];
4
if
(Request.RawUrl.ToUpper().Contains(
“
.ASPX
“
))
5
{
6
if
(
!
Request.RawUrl.ToUpper().Contains(
“
DEFAULT.ASPX
“
))
7
Application[
“
url
“
]
=
Request.RawUrl;
8
}
9
10
}
11
框架页的page_load里加入如下代码即可：
1
if
(Application[
“
urlold
“
]
!=
null
)
2
{
3
if
(Application[
“
urlold
“
].ToString().ToLower()
!=
“
default.aspx
“
)
4
lit1.Text
=
“
<script>window.parent.frames[\
“
mainFrame\
“
].location.href=\
“”
+ Application[
“
urlold
“
] +
“
\
“
</script>
“
;
5
}
if
(Application[
“
urlold
“
]
!=
null
)
2
{
3
if
(Application[
“
urlold
“
].ToString().ToLower()
!=
“
default.aspx
“
)
4
lit1.Text
=
“
<script>window.parent.frames[\
“
mainFrame\
“
].location.href=\
“”
+ Application[
“
urlold
“
] +
“
\
“
</script>
“
;
5
}
不算复杂，实现这个效果也可以用cookie，完全通过客户端来实现，也是不错的。偷懒，就用application了。经测试没啥问题
