two controls communicate

Question

Since I am relatively new to working with C# asp.net 2010 web form controls, I have a question to ask about web form asp.net 2010 table control.
On the new web page I am setting up, I am formatting the web page by using the same master pages, and css style sheets that other pages use for the general company website. I am only using an asp.net 2010 web table control for formatting like the other web pages use.
However when I do that, it seems like the drop and drag controls on the web page to do work correctly together. For example, if I want a checkboxlist control value to tie to a textbox control, the wizard logic does not allow the controls to be aware of each other. When I try to make the controls aware of each other the parameter controls do not work in a where statement. Do you have any suggestions on how to resolve this problem?

I don't understand a lot of what you are saying but in response to the idea of controls not being aware of other controls, that is not done because it would be bad design. Controls should interface with their parent (and Windows) but not other controls directly. Controls can communicate with other controls indirectly through their parent and Windows. So whether you choose to design controls that communicate directly or decide to use a different design, the reason it is not done is because it is not object-oriented and can make programs unnecessarily complex.
Of course I might misunderstand what you mean, since I don't understand why a control that Microsoft has designed to be general-purpose would communicate with another control.
