Actually firebug didnt complain about the xml - it just reported essentially the same error you saw (deep inside the compressed jquery source) - which was basically an attempt to access a node in a null xml document.

The error message (and url) was in the standard firefox error console (Tools|Error console). Usually everything listed there (and much more) also appears in the firebug console - but occaisionally it picks up something that firebug doesnt. Its always worth taking a look when things arent working...

Doh!
I will clean the data and look for & and < > characters, i've done it in the past, just slipped my mind.

Is there an easy way to debug...basically how did you got the link you sent me..just knowledge or from firefox debugger? I have not used the debugger yet in firefox (should do a tutorial really on how to use it), but that link seem to be at the xml stage rather than javascript.

Thanks again Mark

Firefox is reporting that the xml from this request is not well formed:

I dont think it likes the raw "&" in the data.

MarkW...just building a simple grid for testiing some data (18342 records)

http://www.courtnell.com/demo1/nexus.asp

When clicking column to sort (DESC) OR if i scroll to bottom by dragging scrollbar it throws up an error on page: line 13 Object Required

If i scroll down slowly to arounf 17500 records its fine, but then falls over.

the table is simple structure:

docID integer autoincremt primatry key

index1 varCHar(40)

i generated the xml using ROW and ROW ID, i remember you saying grid likes a row ID field, although you did a mod for 3.6 so we didn't actually need one.

Response.Write "<row>"
Response.Write "<cell>" & rs("index1") &"</cell>"
Response.Write "</row>"

And tried with a row id on the key field docID which is an autoincremented field and primary Key

Response.Write "<row id='"& rs("docID") &"'>"
Response.Write "<cell>" & rs("index1") &"</cell>"
Response.Write "</row>"

The code to generate the XML i have used in a few projects and they work fine, and it's strange it works for 17500+ records.

Hope you can see the error your end.

Let me know if you need the code i use for generating the xml from the database.
