It doesn't have any error, the result is the same as if i didn't do the binding
as in
Code:
button1.DataBindings.Add(new Binding("ExternalCmd", testSrc, "SRC_VALUE"));
What i wanted is that changes in ExternalCmd be reflected in testSrc as this is supposed be bind with ExternalCmd., and changes in testSrc need to be reflected in ExternalCmd as well. Currently non of this is happening.
