title: How to create capital letter row for a list of names in an ASP Repeater
body: <p><img src="https://i.stack.imgur.com/paKWj.jpg" alt="enter image description here"></p>
  
  <p>I'm using an asp repeater to display a list of names and I want to display the current letter as a type of grouping header, like in an index page. </p>
  
  <p>The data is sorted alphabetically before binding, but i'm finding it difficult to insert the 'A' and 'B' before the names are displayed.</p>
