title: How to set multiple selected values in asp.net checkboxlist
body: <p>I have a asp.net checkbox list bound to a linq to sql datasource and when I check the item count of my CheckBoxList on the page load event it is 0. I want to be able to set the selected items on my checkboxlist here but cannot.</p>
  
  <p>The datasource's selected event fires after the page load. If this is the case, how can I set the selected items on my list?</p>
  
  <p>If I set the SelectedValue to a value it only displays the last value as selected instead of all the values which are selected. How can I select multiple values in my checkboxlist in the pageload event?</p>
