The Template Design Surface lets you design templates for the items that appear in the tab strip. There are two ways to display the Template Design Surface:
Choose Edit Templates from the RadTabStrip Smart Tag.
Choose Edit Template from the RadTabStrip context menu and select the type of template you want to edit.
Either way, the Template Design Surface appears:
On the design surface, you can drag any controls from the toolbox, as well as typing any literal text.
You can edit templates for all items using the RadTab Template. You can also edit templates for individual tab items. Once you have added tab items to your RadTabStrip component, select a specific item from the list of item templates in the Smart Tag, or edit them all at once by choosing Edit Template | Item Templates from the RadTabStrip context menu.
When you have finished designing your template, choose End Template Editing from the RadTabStrip context menu or Smart Tag.
