DataBinding: 'System.Data.DataRowView' does not contain a property with the name

Question

Hi Expert,
I am new and a beginnger in C#.  Hope you can help me.
My database is working fine, I am doing CRUD for my project and i am currently doing an insert.
I can do insert in browser but when i want to add the information,
it will divert from browser to my aspx.cs pointing my code and prompt me an error saying that "DataBinding: 'System.Data.DataRowView' does not contain a property with the name"
Any idea how can i solve this? Thanks!
