You need to add a Repeator or GridView or Datalist control to bind the list (dates) inside the ItemTemplate of GridView.

Hash tables have keys and values so you can't bind your grid using the key names (as you are doing) because the key names are not properties of the hash table. If anything, you could have columns bound to Key and Value; however, your data has a List of things (dates) and the Gridview won't know how to bind this list to one column. As AVD suggested, you need to have an item template and inside it, have another gridview if you want to bind a data structure like this to a grid view.
