The Script Resource and the Web Resource files are generating intermittent errors in my application. I have been trying to chase the cause of the problem but to no avail. I notice that the “d” parameter that is passed is some how corrupted and I can’t for the life of me figure out what’s causing this parameter to be corrupted. I noticed that JavaScript code that in my application is some how getting intertwined with the hash code that’s generated for the “d” parameter.

Page location: /ScriptResource.axd?d=70kBR-jPBTx9R89F Requested Url : http://panasonic.premiumstore.com/ScriptResource.axd?d=70kBR-jPBTx9R89F

It appears you are referencing an empty viewstate(object = nothing).

Try this....

If ViewState("VarName") ISNOT Nothing THen
'Do your stuff
TextBox1.Text = ViewState("VarName").ToString()
Else
'ViewState = Nothing
'Reset your viewstate...
SCOPE:  it is only good for the life of the PAGE....redirect to same page sets it to nothing
End IF

If this doesn't solve it, strip your code down and paste it in the forum and I'll see if I can help out.

Later

Opps misread your post.  Above post is not the issue!

Strip your code down and post what is causing the issue and I'll take a look.

Hey Thanks a lot for you Help.

Ok this is what I have Notice in my analysis, the request for the script resource seems to be always intertwined with the same JavaScript code, I have included a line from my error log that shows the requested Url that caused the issue.

as you can see the "d" parameter is corrupted. What happens here is that the System.Web.UI.Page.DecryptString will throw an Invalid view state error when it tries to decrypt this string. What I would like to know is how can this string become this corrupted.  I took a look at the JavaScript and everything seems ok to me, the only odd thing is that there are some comments in the code which is comment with /* to denote that the line are just comments.

Are you using fiddler?

No. These are errors that visitors visiting the site are getting. I am just tracking the errors from the Global.ascx file.

I am not able to reporduce this issue.

Make sure these tags /* have ending comment tags as well.  It appears like they don't with the way your js code is appending.

/*
Comments
*/

It appears that each time a visitor is hitting a certain piece of js code this is occuring.  Dig in your IIS log by IP to see the path they are taking to get the error.  You should be able to reproduce it...  That's the key!  I'm guessing your missing a  single apostrophe in one of the js functions.  Look in your js code above the function: runSearchForField

Here is a copy of the Javascript Code from the page, with the comments and all. I will start to Dig through the IIS logs to see what I can find.

<script type="text/javascript">

function runSearchForField(eventObj, id)

I think it's somewhere else.  This js block looks ok.  Where is this text located?

"StoreUrl' is already set"

That text is also located in that javascript code block, its part of the comment. The actual string is

/**

* Lawrence 4/17/2008: Perform search redirect when ENTER is pressed.

* TN_Search_JS must exist as an HTML textfield on the page.

* Assumes that a global variable called 'globalFullSubStoreUrl' is already set.

*/

The code that sets the variable runs in the code behind file. Shown below

Me.TN_Search.Text = getSearchValue()

Me.TN_Search_JS.Value = getSearchValue()

Me.TN_Search_JS.Attributes.Add("onkeypress", "return runSearchForField(event, '" & TN_Search_JS.ClientID & "');")

Me.TN_Search_JS.Attributes.Add("onfocus", "updateSearch('" & TN_Search_JS.ClientID & "');")

Me.TN_Search_JS.Attributes.Add("onblur", "updateSearch('" & TN_Search_JS.ClientID & "');")

Me.js_search_button.Attributes.Add("onclick", "runSearchForButton('" & TN_Search_JS.ClientID & "');")

'Lawrence 4/17/2008: Don't show loader since we are now using javascript redirect search.

'Me.search_loader.Attributes.Add("style", "visibility:hidden;")

'IMG_loader.Attributes.Add("onload", "hideme('" & Me.search_loader.ClientID & "')")

'CMD_Button.Attributes.Add("onclick", "showloader('" & Me.search_loader.ClientID & "')")

I am currently going through the IIS web Log but this thing is hugh, I guessing it will take me sometime. Its over a GIG.

Hey thanks alot for the help again.
