My question is about asp.net and hidden fields Here's my error message. I'm using asp.net.
'default2_aspx' does not contain a definition for 'hfEmployee_ValueChanged' and no extension method 'hfEmployee_ValueChanged' accepting a first argument of type 'default2_aspx' could be found (are you missing a using directive or an assembly reference?)
Can someone tell me how to fix this? I'm new and don't know how to create a definition or fully understand what this is saying. Thank you.
