Ramli, you cannot select a tabpage based on data on a nice way. There is only one default tab page (yes/no). Good one for the [Idea Forum] ;)
If you really want this, you can add three tabs. Each tab contains the same pages. On each tab, the default tabpage is different. You can set the visibility on which tabpage to show based on an enumeration. Make sure that the content of the tabpage is a snippet...
Unfortunately not as far as I'am aware. You could create three different pages, set defaults for every page and make use of snippets...
Yeah was hoping i would not come to that, is was thinking to create a enum i set in the mf . on loading the page and using conditional formatting combined with a "javascript show" action loaded from the HTML widget. Do you suppose this could work?
