ASP.NET
The page works great, can edit and save, move back to home or another page from menu bar but can not log off from page or automatically log off from page, just get the error message, if I continue it goes back to the log of page and all is good again
The problem arose when I put the two dropdownlists into the formview
here is the code

What I have tried:

I have tried many solutions posted as the answer to this problem but nothing seems to work, I don't understand how the page works normally like the fields update, the dropdown lists are bound but when I either click on the Log Off button or click on the add button on to add the implants to a grid it reports the error event
"
databinding methods such as eval(), xpath(), and bind() can only be used in the context of a data-bound control.
"
The only thing that my obviously unlearned mind can think of is that the two drop-down lists are bound to the table that the data will be saved to while the list is populated for another table through an sqldatasource.
Any help with this would be really great.

As it only happens when logging off, it might be helpful if you included any code involved in the logoff process!
Member 14560926 26-Aug-20 16:10pm    
My log off process is the out of the box vs2019 logoff that is created when I started the website. so it is the standard authentication process. This problem only happens when logging off from this page.

So what LogoutAction are you specifying? You say "All it is doing is closing down" so that implies you are doing something additional, rather than just clearing the authentication ticket. (What authentication method are you using?)
Member 14560926 26-Aug-20 17:25pm    
I have not made any changes to any log off procedure, the one I am using, I suspect to be
using Microsoft.AspNet.Identity.Owin;
that is on the login.aspx page. I did make some changes to the logon page that created some session variables.
