I am creating a prototype with tabs similar to the tabbed web browser. I add 2 tabs on intial load. the first tab is bound to a user control and the second tab is a empty stub to create a new tab(just as in tabbed web browsers). When I click on the stub tab, I add a new tab and a pageview to assign to it and also bind a user control to the pageview. the issue is, this newly added tab renders the contents of the previous filled tab instead of empty controls. I also would like to add a little close button to be able to close the tabs. Pls provide any solutions.
