I've used repeaters many times without problems but something is going on here. I have a repeater and I'm subscribing to the itemDatabound event, But when i click the button (which is a linkbutton inside my repeater itemtemplate) it does not go to the ItemDataBound

<asp:Repeater ID="rpt" runat="server" OnItemCommand="rpt_OnItemCommand" OnItemDataBound="rpt_OnItemDataBound">
    <ItemTemplate>
        <li>
            <asp:Label ID="Label" runat="server" />
            <asp:LinkButton ID="LinkButton1" runat="server" CommandName="edit" CommandArgument='<%# Eval("MyID") %>'
                Text='<%# Eval("Title") %>' />
        </li>
    </ItemTemplate>
</asp:Repeater>


    protected void rpt_OnItemCommand(object source, RepeaterCommandEventArgs e)
          {
              if (e.CommandName == "delete")
              {
                  //Data.Contacts.RemoveAt(e.Item.ItemIndex);
              }
              else if (e.CommandName == "edit")
              {
                  EditIndex = e.Item.ItemIndex;
              }
              else if (e.CommandName == "save")
              {
                  //          
              }

           }


protected void rpt_OnItemDataBound(object sender, RepeaterItemEventArgs e)
{
     if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
      {

        if (e.Item.ItemIndex == EditIndex)
        {
          // never come to this line.... after the user click on LinkButton

        }

      }
}

Don't know if this helps but you must call DataBind() in order for for the OnItemDataBound event to fire. Also my guess is you are trying to set the EditIndex in the OnItemCommand and then use the value in the OnDataBind event. The events fire in the order OnItemDataBound then OnItemCommand so the EditIndex wouldn't be correct anyway in that situation.

Add rpt.DataBind to the OnItemCommand. This workded when I tried it from your code, NOTE that you will be binding twice if you aren't using !IsPostBack for original data bind.

  rpt.DataSource = strings;

  if (!IsPostBack)
  {
       rpt.DataBind();
  }

 protected void rpt_OnItemCommand(object source, RepeaterCommandEventArgs e)
 {
      if (e.CommandName == "delete")
      {
          //Data.Contacts.RemoveAt(e.Item.ItemIndex);
      }
      else if (e.CommandName == "edit")
      {
          EditIndex = e.Item.ItemIndex;
      }
      else if (e.CommandName == "save")
      {
          //          
      }

     rpt.DataBind();

   }
