I am using a textbox in a WPFApplication and I want to implement a dependency property that will decide whether textbox allow input as numeric or alphanumeric.
there are at least three ways to do this.
1) derive a sub-class, adding your dependency property
2) create an attached property
3) create and attach a behavior (using the expression SDK)
