ListBox / Header and Footer Templates

 
  • Birthday present for Emily

  • This example shows how to use header and footer templates with RadListBox. You can add header/footer template both declaratively and from the code behind, in pretty much the same way as all other types of templates.

    You can add html entities as well as server-side controls to the header/footer templates.

    Once server-side control is added to the header/footer template it can be accessed using the FindControl method provided by the Header/Footer properties of RadListBox.
