I've got a vb.net page that has a company dropdown which causes a postback, and I'm wanting to change the logo at the top of the page with the logo of the selected company. The header bar which has the logo in it is in a user control called Nav.ascx. Due to the order of elements loading on the page, I'm not finding a good way to display the logo in the header unless the user reloads the page or navigates to another page. If I try to reset the logo in the dropdown.SelectedIndesChanged event, that's not working. Any ideas how best to accomplish this?
