  Binding the NameValueCollection to for instance a Repeater will only give you access to the Keys.
  You'll find that the DataItem is actually a string.

  One way to do this is the following:

  Repeater definition in .aspx:

  <asp:Repeater ID="DataViewer" Runat="server">
  	<ItemTemplate>
  	<%# Container.DataItem %> - <asp:Literal ID="Value" Runat="server" />
  	</ItemTemplate>
  </asp:Repeater>

  The Container.DataItem will be the Key of the item in your NameValueCollection.
  To get the Value right, you'll have to handle the ItemBound event of your Repeater:
  
  

  this.DataViewer.ItemDataBound += new System.Web.UI.WebControls.RepeaterItemEventHandler(DataViewer_ItemDataBound);

  The handler looks something like this:

  private void DataViewer_ItemDataBound(object sender, System.Web.UI.WebControls.RepeaterItemEventArgs e)
  {
  	if (e.Item.ItemType == ListItemType.Item
  		|| e.Item.ItemType == ListItemType.AlternatingItem)
  	{
  		string key = e.Item.DataItem as string;
  		Literal Value = e.Item.FindControl("Value") as Literal;
  		Value.Text = _SomeData.Get(key);
  	}
  }
   
  And then of course the DataBinding itself:
   
  NameValueCollection _SomeData = new NameValueCollection();
  _SomeData.Add("Key 1", "Value 1");
  _SomeData.Add("Key 2", "Value 2");
  
  DataViewer.DataSource = _SomeData;
  DataViewer.DataBind();
