Did anyone noticed that MS says "...ValidationSummary property..." There is no such property. There is a ValidationGroup property, yes, but no ValidationSummary. ValidationSummary is a control, not a property. Can this be just a typo from Microsoft, or I'm missing something?

I recently bumped into this while trying to debug a page with 2 ValidationSummary controls (one for "ValidationGroup1", the other for "ValidationGroup2"). Both summary controls show up when I submit the page. Both of them show all the error messages from individual control validators despite the setting of ValidationGroup property.

I'm stuck. I'm using UpdatePanels and this might be the cause. I don't know...

Did you just set the validationgroup property on both validators, textboxes and validation summaries, or perform some other (eg page.validate) function on the action for switching panels?

That's actually rather quick. I didn't know that until now. Good to know since I use validation groups a lot.

Quick thought: Given that the stuff you put in session is implicitly serializable, why not just let an XmlSerializer do the grunt work?

I use the code below for dumping an object into a text file (this is just some stub code, so performance is not an issue); you could modify it to dump to the output stream instead:

public static void SerializeToFile(string filepath, object instance)

{

XmlSerializer serializer = new XmlSerializer(instance.GetType());

Stream writer = new FileStream(filepath, FileMode.Create);

serializer.Serialize(writer, instance);

writer.Close();

}

(Again, just a quick thought, I might have missed a point or two :) )

Hi Nawaz,

You can use the <trace enabled="true" /> which will show you a lot of information. It shows you what is in Session, but only at the top level. In other words, if I put an object in Session, it will simply call the "ToString()" method of the object, which will just give me the type of object it is. It does not read all the properties of the object and display them as well.

Hi,

Its a nice little piece of code, I was wondering if you could use the APPLICATION-LEVEL TRACE LOGGING?

Isnt it what could also be used for this purpose with <trace enabled="true" /> tag?

THe one thing I wish you could do as a developer is look at what everyone has in their own sessions... Even if you had to do this from the ISS Server itself. It would be amazing to switch a value in another person's session rather than force an update to a DataBase only to call an event on their next postback :\

April Links. If ScottGu can do it, I can do it as well :-)
