Javascript changes not saved

[ken s]

I'm using Javascript to change a value in an asp:textbox control on an
asp.net page, then submitting the page and persisting the data using c# code.
I can see the value in the textbox change when the Javascript runs, but when
the page is submitted, the c# event code still sees the original value in the
textbox, not the value that was updated by Javascript.


Here’s the javascript code that changes the value:

document.forms[0].txt1.value = calcCigScore();
alert (document.forms[0].txt1.value);

The alert shows me that the value has changed (I can also see it change on
the page).


And here’s the c# code from the SaveRecord event on the aspx page:

mIntake.CigScore = int.Parse(txt1.Text);

When tracing through the code, I see that txt1.Text still equals the value
that was originally loaded into the page.

Is there a reason why .Net doesn’t see the updated value? Anything I can do
to change that?

Thanks

Most likely you are running up against ViewState. Set up Page_Init() and
look at the value there. Then, check again in Page_Load (ViewState runs
between the two).

It is also possible you are rebinding in Page_Load, which happens prior to
the event handlers for controls (button submit, for example).
