call JavaScript - jQuery code from ASP.NET Server-Side

  
jQuery got so close to me lately that I can see myself adding the scripts to my project almost unconsciously. The thing is, jQuery is very useful for me, in almost all situations and it has been a do or die enhancement for all my project since I first put my hands on it.

Of course while using it, you encounter few situations which need a bit of research to solve, mostly when you are trying to combine it with some other technologies like: UpdatePanels and ASP.NET Ajax. For instance there are many situations when I would like to run some jQuery magic based on some decision that I make on the server side.

Linq2Sql error: "Invalid attempt to call Read when reader is closed."

  

I've read up on this error from other posts and on other sites, but haven't found a solid resolution to the issue yet. My setup is as follows:

I have a RepositoryBase class that fields certain db calls that all repositories need to perform. In one such call, "GetSecurityGroup", it works most of the time, but will seemingly at random throw an exception with the error "Invalid attempt to call Read when reader is closed." All other Repository classes inherit from this one, and they all use the same DataContext object, which I understand isn't thread safe. Since there could be multiple calls to the DataContext object on the same page, perhaps one is using the DataContext when the next tries to do so. I'm not sure. What can I do to ensure this doesn't happen?

jQuery Call to Web Service, with Punctuation

  
Hello everyone! I hope you're all having a nice week so far. I'm trying to call a web service and the passed string may have punctuation, depending on what the user types in. I currently have an HTML textbox and a jQuery call to the .NET web service.  I definitely think the string with punctuation fails because jQuery will send the string wrong, so I tried a few different javascript encoding functions I could find.  I was never able to encode it successfully and decode it in .NET, saving the string with punctuation.   Basically I have a textbox that a user can update their status in.  If the user wants to use punctuation, I'd like them to be able to.  How can I accomplish this with jQuery and .NET?
