Binding an object property to a TextBox
This is by far the easiest thing to do, and there are several examples online already. Consider the following Example:
edc.tb3AColor1.DataBindings.Add("Text", this, "A_ColorMunsellNumber");
The example shows a panel containing a TextBox (tb3AColor1) where the DataBindings collection adds a binding from the Text property of the TextBox to the property A_ColorMunsel_Number property of "this" object. That's pretty much all there is to it.
