I'm beginning to use ASP.NET. I'm trying to do some "code behind" pages but I've 2 problems :<BR>1 : I declare two public variables as label in the same class declaration (I make a single database access to return 2 results that will be stored in these 2 variables), but I can't give them a value using the expression myvariable.text and myvariable2.text to use them in two separate user controls with <asp:label id="myvariable" .... (error object null)<BR>2 : in the same code behind file, I receive an error when I'm triyng to use a simple expression like left(myvariable,2) ??!!?? : left is not declared???!!!
