Let me know if I'm lying. I haven't used the released version of CPhog for quite some time. Which means we should probably release a new version. ;P The way to enable that feature is to switch the forums to Thread view, then click on the little Quick Refresh button next to the thread you want to load.

Jan my aspnet_wp.exe takes up 86,500 K when it isn't being used. So 100MB is easy to eat up, nothing you can do about it. One thing to double check is to make sure that debug="false" in the web.config for that will cut down on ram. Also since it is an ecommerce site, are you storing images on the server? Make sure they are compressed jpgs and not gifs. Also, when I code I use the Using keyword whereever possible, it calls an objects dispose method where available. One more thing is not to use arrays. They are inneficient. Generic Lists do much better if you can use them instead. I didn't get any requirements for the signature

What you want to do exactly i did not got. If you want to access the checkboxgroup in the formview try CheckBoxList chkGroup = objFrm.FindControl("objChkGroup") as CheckBoxList ; and iterate through it. int index=0; for(index =0 ; index < chkGroup.Count ; index++) { } I hope this is your problem

Neither in A or B the businesslayer has any knowledge of it's representation (in my examples)

Probably, looking up the schema is a good idea and I am not at all against it. The problem is, that mingling xpath with schema to create missing nodes via dom is something extremely complicated. I wouldn't even know where to start. That's why I thought, that XUpdate would help me there, as it is an developed language for more or less this purpose. At least I am thinking it is. I just looked it up a few days ago and haven't found anything better since. But I have no idea, if XUpdate does not have any pitfalls I am not aware of, if the implementation, I found, is ok and most importantly, if there isn't some other, more straight forward way. As for explaining my somewhat confusing (I admit) text: I wrote a provider that allows me to update and delete nodes via xpath. That's something quite easy. Now I needed to insert nodes as well and as the xpath was something I already had in my classes, I tried to implement the insert as well via xpath. I failed at that and I am pretty sure that xpath just is not the right expression for the job. Even though others at cp have tried something quite similar: http://www.codeproject.com/csharp/xpathstore.asp So my examples have to be read with that bias: to use an xpath as an more or less equivalent to an sql insert statement. I query: /foo/bar[action='4']/element Now, this node does not exist, so it should be created (and it's predecessor bar with the attribute action=4). foo exists, so nothing needs to be done for it. Same aplies for /foo/bar[4]/element, just the attribute has to come from somewhere else (I can provide for this). /foo/bar[5]/element should fail (because there is no element bar[4] for it to be inserted after) Thanks for sharing your thoughts!
