Load Dynamic XML from object (.NET)

Hi,

I'm attempting to put an AW grid on my page, but I have a dillemma when attempting to figure out what to do with my data.

I have a webservice which will generate the data I require, but after it returns I need to strip some extra data off, such as schema information. I cannot edit this b/c its coming from a legacy platform.

After that, I need to load it into the Grid. However, when users enter the data I do not want their changes to be saved until they hit a "submit" button. It seems that using a webservice call from the html such as table.Seturl("thiswebservice.asmx/mywebmethod"); will save my data every time a change is made.

Is there a solution to this?

In addition, I require the ability to refresh a column's data at an interval (say, every 5sec.) Does AW support this?

Thanks,
