Onrowupdating not working
On Row Deleting - can call registered event handlers" I couldnt figure out how to continue this thread, but the issues in it are related so i'm including it as a reference.i get that you're are just taking the "text" from the imaginary textbox in your gridview, and putting it into a string. also throw a breakpoint on your Update Method to see what the variables are holding when passing in. I have a web application that shows a controls group based on a result set from a database.Description: An unhandled exception occurred during the execution of the current web request.Please review the stack trace for more information about the error and where it originated in the code. Format Exception: String must be exactly one character long. i find it hard to understand that since you do not have template fields, and you are using bound fields, there is no way possible that parsing it into a textbox would work, considering there is no textbox(es) in your gridview to being with.
