Thanks. I am using Firebug. Very nice tools. I'm slowly getting up to speed on how to use this tool. I have a JSON table with subtable working now. I have add, update, and delete all working. I have noticed some erratic behavior (the subtable disappears) in ie 7 and ie8 comptability mode (ie7) but great stability in standard ie8 and firefox when adding records to a subtable.

Thanks again.

Also - a great tool for debugging request vars (and lots of other stuff) is the Firebug plugin for Firefox. If you ain't using it, you need to be.

You would use the same methods as for PHP. There will be POST and/or GET server vars passed and you just need to grab those and pass those along as params to an SP or use them in a direct SQL statement (I would go the SP route to keep it secure). You can trust the POST vars, but not any custom GET vars you might be passing.

HTH,

Thank you so much. That worked beautifully and the JSON performance is incredible. Do you have any examples of adding rows, editing, and saving via asp? I'm sort of at a loss at where to begin. It's probably not that hard.

I'm using inline editing.

My goal is that the add button creates a blank line, the save button obviously saves (either on a line by line basis or the records that have been changed), and the delete button obviously deletes the line. I'm just looking for where to start.

Thanks so much,

I use jQuery with classic asp and use ajax requests via JSON returns. It is very fast and much cleaner (IMO) than XML. There is a JSON ASP Project that is really nice.

For example, this is how clean the JSON return can be:

Set member = jsArray()

While Not (rs.EOF Or rs.BOF)

Set member(Null) = jsObject()

For Each col In rs.Fields

member(Null)(col.Name) = col.Value

rs.MoveNext

Wend

member.Flush 'Writes out (returns) the object in JSON format to the calling script

Here is where you get it:

I love it.

Issue resolved:

Adding the following code to party.xml.asp resolved the issue.

Response.contenttype = "text/xml;charset=utf-8"

When addressing the entire 150,000 records, it is still slow generating the XML. Are there any suggestions? Is JSON any faster?

I am trying to integrate jqGrid into classic ASP. I have successfully tested using the array method for populating but I need to have a source of up to 150,000 records and think XML would be more efficient. I am open to ANY suggestions someone may have. I am working on a proof of concept and been unsuccessful for two days. .NET is not a short term option. There is a plan to convert to .NET in the next year.

The error I am receiving is "Error: Object Required" referring to line 641 of the debug jquery-1.3.2.js file.

Thanks for any insight or assistance in advance.
