I put a RadSplitter onto a page (parent.aspx) that has two vertical panes. On the left side there is a navigation menu. If you click on an item of the menu, it will open the .aspx pages on the right side next to the navigation menu. Now I want to redirect the web application from pages that open in the right side pane (I want to redirect to a complete new webform, for example Default.aspx).
I want to redirect to another page, but when I redirect the page, Default.aspx opens in contentPane (right side). I want to open this page in a new page.
