Placing Items on a Tab Page:

Once you create a tab canvas and related tab pages, you have to place individual items on the tab  pages  in which  the  end  users  can  interact  with  at  run  time.  To complete this, you have to do the following:

• Open the Property Palette of the item
• Set the Tab Page and item's Canvas properties of the item to the desired tab page and tab canvas.

Note:  Show  the  tab  canvas  as  it  sits  on  top  of  the  content  canvas,  through  selecting  View Stacked View → Layout Editor.
