Hi Mark,
Thanks for posting in the community!
From your description, you used some HtmlInputText controls(set ast
runat=server) on an ASP.NET web page. However, you found that when you
posted back the page, the values in the HtmlInputText Control can't remain,
will return back to the original value, yes?
If there is anything I misunderstood, please feel free to let me know.
As for this problem, I'd like to confirm some further things on it:
1.You mentioned that when you input a value "2" in the html textbox and
post back the page, after that the value returned to "1", yes? Are you sure
there is no other code in codebehind will modify the textbox's value?
2.As you mentioned, you tested use the numeric value such as "1","2". Have
you tried using string value. For example, put a string like "Hello World"
and post back to see whether this remains?
3.I still feel this problem a bit strang, would you please try creating
another new project and do the same test in it? Also, do be sure that you
have'nt disable the ViewState of the page at PageLevel(@Page directive) or
Application Level(web.config) or ..
And here is a example page I used to test, maybe you can also try testing
on this page to see whether the problem remains:
