Producing warning messages

Kontakentee

Please, I want to know how to create warning yes/no message boxes using C# and ASP.NET. For example, Are you sure you want to delete this?

Use the JavaScript method; confirm if(confirm('Are you sure you want to delete this?')) do something

Thanks Mark. But please, explain to me how to use the confirm method. When I used it an error is displayed on compilation "The name confirm dosen't exist in the current context"?? Do I have to provide code for this method before calling it?

You use it as I've given within a JavaScript block on your page, nothing more. Perhaps you could show a sample that is giving you problems, or search this site or others for examples.

Hi Mark, The problem is that I'm using C# to write my code. On confirming the delete message, my program should delete all information related to a student. So I create a new SQLDataSource and then write the delete command as follows. SQLDataSource DeleteStudentInfo = new SQLDataSource(); DeleteStudentInfo.DeleteCommand = "Delete From Student Where StudentID = @StudentID"; Then I identify my delete parameters. How to insert javascript code before my C# code shown above? Thanks Mark

You don't. JavaScript is run on the client, C# code is run on the server. I think you should reread a couple chapters in the book or ask the professor or TA for help, your missing some concepts.

Honstly, I don't know anything about javascript, only heard about it. But you don't have any suggestions for me? Actually I don't know where to insert the code you have given me? Do you know a professor or TA that I can ask? Also, Do you have a good book that I can work with it easily? Thanks very much for help and sorry for any inconvenience I'm causing.
