Lets say I wanted to create my own custom validation system. Is there a way to pull the values from controls without testing whether the control is TextBox or DropDownList, further up the inheritance chain? It seems there are certain
things groups of controls have in common like ".Text" property for text-based controls and ".SelectedValue" for multi-select controls. Are there any other commonalities like this and how would I go about manipulating them?
