An interface has a few tabs on it. (Tab 1 to Tab5). Tab 1 is labeled Item Category Level 1 and the following tabs are named accordingly. Tab 2 is Item Category Level 2, Tab 3 is Item Category Level 3 and so it goes.
Item category level 2 has a combo box that uses a data binding property that will allow it to be binded to Item category level 1 via a Binding source to display the data from Item Category Level 1 in it. The same goes for all other Tabs.
Item category level 2 displays the data appropriately, but other tabs do not display the data at all.
Why is this and how do I correct it?
