just want to check whether i am doing this right,i am using visual studio 2008 and have inserted an expression in the backgroundcolor properties for one of the textbox in the table which is suppose to highlight the textbox accordingly. the expression is:-

We are planning on creating reports to be run on the same computer that the database application is running on. which of these is the best approach? (SQL Server Reporting Services or creating a rdlc ReportViewer report) Also I tried to locate detailed rdlc ReportViewer report tutorials both in books and online and found none. It's probably because I'm looking in the wrong places.

what I am trying to accomplish worked with the code in the last thread I posted a while back. I still am using this code, however, I changed the window size to work better and gave it a nicer background for the title screen of my project. Now what I am working on at the moment is making a settings form that has 2 labels. One for "Default" Layout and one for "Plain" layout. When default is at start, the default label is disabled,and when plain layout is clicked, the button is disabled and default button is enabled.Basically, this is a toggle switch for default or plain where if one is enabled, the option for it is disabled and the other is enabled.My problem is that when I switch from Plain back to default, the background Image will not switch back from the plain background color of "control"Here is my code:
