    So do I, it's over your head. Try looking here[^] and reading about the events, like DeleteCommand and ItemDataBound

    Ok. I am not an expert but have a lot of experience. What would be a better solution to that ? "SELECT username FROM mediaComments ", in-line sql, another novice mistake I looked at ItemDataBound before (Occurs when any button is clicked in the DataList control. ) The point is not to even show the delete button for the user who is not the poster of the comment. As to templates, Repeater, and Data List can be templated. If not please explain what you mean. Thanks.

      A better solution to in-line SQL? Ever heard of stored procedures? :rolleyes:

      Really? Then look again "Occurs when an item is data bound to the DataList control."[^] You are using template, but using the methods incorrectly.

      "Response.Write("dr" + dr[0] + "<br />");"

      ; You don't need this. Use the template to show your items, that's what it there for. You should have enough information now, I suggest you read a little more and look at some of the many examples available. If you need any more, I'll have to start charging you. Where should I send the invoice?

        Sure I heard of stored procedures, I use them when I find necessary. "Response.Write("dr" + dr[0] + "
        ");" is for testing purposes. A lot of programmers do it when testing the results of the query. All the items are templated actually. You are right i mixed it with itemCreated. Thanks for the help.

          It's a myth. IMO, nothing wrong with inline SQL other than the difficulty of recompiling code when the DB structure changes. This can be avoided by abstracting the table structure using views. So still you can write inline SQLs safely. Please do correct me if you felt I am wrong.

            Where do I start? This argument has been raised several times. Inline doesn't allow for separation of the business logic from the presentations, which a good design does, and increases maintenance and development. 10 apps with the same SQL statement must each be changed, rather changing one stored proc. Worse yet, if the schema changes, say a table or column is renamed, all statements must be changed instead of changing one stored proc. Inline statements also don't allow the RDBMS to optimize the execution or otherwise cache it for better performance. Just few of the many reasons. Then again, if you don't care about robust, well designed and performant applications, keep using inline statements.

                That is true. But if you use a statement only once it's ok to use inline statement.

                  :laugh: :laugh: And if that one statement is executed 1000 times, what does that do for the performance of your system?

                    I actually meant execution because that's what matters. Used means executed. Any time the statement executed more than in one place it's easier to work with stored procedure, and modify it.

                      has nothing to do with level. It's a matter of preference.
