Change property binding at runtime by trigger

Hello,

I have a combobox (call it ComBo1) and a button/combobox any other control (call it Control) and I need to change binding to another property on Control, when value of binded property of ComBo1 is changed.

For ex. I have Value1 and Value2 which I must bind to Control and ComboValue, which changed dependent from ComboBox selection. And when ComboValue changed I must change binding on Control from Value1 to Value2.

I have a lot of such controls and I wish to know is it possible to change binding from XAML with datatriggers or whatever?
