Web Forms :: Textbox --> Save
Jan 21, 2011
In my code i would like, to show in a textbox a text from a file, then let the user change anything they want then when they click the save button, i would like the changes to be saved on that file. I wrote all the needed code, but there is something not working, the saving part, the problem i'm having is, it always save the original text, it has no idea about the changes made, so the text file data is always the same.... I think I should use some "New Instance" to fix this problem ... but i don't know where/how.
[Code]....

I am new to ASP.net and I am trying to save the state of some textboxes on redirect. I have a dashboard interface with drilldown. The main dashboard page has a date range option (textbox for both start date and end date) for the information displayed and I need to save the date range chosen by the user. I know that I can put the info into a session variable to use in the page that I am redirect to, but when I hit the 'go back' button on the drilldown page it returns to the main dashboard page and the textbox value is lost. I ahve also tried saving the viewstate, but could not get that to work either. What is the best approach to solving this problem?
edit: In case it matters, I am actually using the jQuery $(location).attr('href', url); to do the redirect because some of the chart objects I am using cover html or asp hyperlinks in IE.

I'm trying to save the text in a textbox that was loaded from sql server and changed by adding a "<b>" to the text.
The call fails with a Server 500 error, *BEFORE* it even gets to the btnSave_Click.
It's failing somewhere in the Java Script in the dynamic ScriptResource file.
The old text in the box was "This is a test"
I changed the text to "This is a <b>test</b>" and clicked btnSave.
The Java Script it fails at is:
************************
_this._clearTimer();
_this._responseAvailable =
_this._webRequest.completed(Sys.EventArgs.Empty);
}
_this._xmlHttpRequest.onreadystatechange = Function.emptyMethod;
_this._xmlHttpRequest =
true;try {finally
{if (_this._xmlHttpRequest !=
null) {null;
***************
Which would probably tell me something if I could read Java Script better... but using the immediate window to try and get the value of *anything* just gives me null.
