How do I Bind in ASP to a SQLDataSource?

StackOverflow https://stackoverflow.com/questions/6373286

문제

I'm trying to wrap my head around databinding using a sqldatasource. Right now I have a sqldatasource, databound fields, and template fields that I bind using: <%# Bind("ColumnName") %>. I understand databound fields, but when using the "Bind" command on a template field, how does it know the value to put there? Does it find the ID for the row and then use the sqldatasource to get the value?

Also, how would I go about doing the same thing as "Bind" in ASP, but in the C# code behind instead?
