How to display value from not selected combobox c#

Question

I need to display an unselected ComboBox value.

I have 10 ComboBoxes with tag values 1 through 10 .

When I select a ComboBox with a tag value of 1 , I have to check what is displayed from the ComboBox that has a tag value of 2 .

Selecting a ComboBox with a tag value of 5 should give me the value of the ComboBox that has a tag value of 6 .
