Hi @Simon,
is it posible to use use tag like in like in windows desktop software
Control.Tag Property works in Windows Forms project, it does not work in Web Form controls. Because the Web Form control does not contain a Tag
property. Therefore it is impossible.
For more details, just refer to this official doc: Properties - TextBox Class.
If you need to store some additional data, maybe you could try using ViewState
instead. Simply refer to this simple in doc: Saving Values in View State.
Best regards,
Xudong Peng
