Hi,
ASP.NET automatically captures input controls data (for example, a TextBox) when you post back to the same page. All data are discarded if you navigate to another page (or even reload the same page). Neither case has anything to do with the TabStrip control. I would recommend you to use standard ASP.NET/HTML elements to get it working first, then put the TabStrip back in.
To dynamically create tab items, you would do something like this:
Code: C#
//Create a new tab item
EO.Web.TabItem newItem = new EO.Web.TabItem();
...setting newItem properties....
//Add it to the tabstrip
tabStrip1.Items.Add(newItem);
You can also call Remove on Items collection to remove a tab item. Please see class TabStrip, TabItemCollection and TabItem in the reference section for a complete list of what's available on these classes.
Thanks!
