We wrote this code behind for our home page in asp.net #C project

and we are facing errors with (command argument+command name).

And these are the error messages:

1:

Severity Code Description Project File Line Suppression State

Error CS1061 'EventArgs' does not contain a definition for 'CommandName' and no accessible extension method 'CommandName' accepting a first argument of type 'EventArgs' could be found (are you missing a using directive or an assembly reference?)

Severity Code Description Project File Line Suppression State

Error CS1061 'EventArgs' does not contain a definition for 'CommandArgument' and no accessible extension method 'CommandArgument' accepting a first argument of type 'EventArgs' could be found (are you missing a using directive or an assembly reference?)

If anyone can help us on what to do I'll be very thankful
