what i know for a fact is the is a field that is set for 2000 characters but once this field goes over 350 the error gets triggered, other than that the application is fine

But that is hardly relevant. Somewhere in your application something is being triggered which causes a null reference to be used. The only way to discover where that is and why, is to do some detailed debugging.

Good. Check the line
Processor.Data.WebsitePageDownload.AcceptChanges()
Set the cursor on the AcceptChanges method, hit F12. Set breakpoints there, and make sure that the method does not swallow the changes.

not sure what you mean swallow, but the data is updated but there seems to be a problem when it returns to the UI

I'm expecting a try-catch in that method that hides the exception that is thrown.

Is the data updated beyond the 350-char mark? How do you know there's a problem? Do you have an exception and a stack-trace?

yes, but cannot be limited because the length of the url entered is unknown

This is not helping much, we're talking about different things. If you can fix the size of the column in the grid in where it is displayed to 100 pixels, then you can still enter long strings. It would prove whether or not the observed behaviour is caused by the internal resizing, or somewhere else. If fixing the width helps, then you'll need to look for other alternatives or find a fix. If fixing the width does not help, then the error is occurring somewhere else.
