DropDownLists not displaying values!

[net123]

I have a web form in which on Page_Load 4 DropDownLists are populated with data from a database. on ButtonClick, a datagrid is displayed with results from the search page. The web form also has other text boxes to search by aside form the dropdown lists as well.

When the first display of results are shown, if I try to narrow the search by picking from one of the dropdown lists, some values are empty, i.e. doesn't display anything.

For example ddl:

It should display:

West
East
North
South

But instead shows something like this:

West

North
South

Can you see the effect that I'm getting? Why such behavior?
