Use Selected="true"

<asp:ListItem Selected="true">All</asp:ListItem>

Your code would be

<asp:CheckBoxList ID="chktopics" runat="server" RepeatDirection="Horizontal" 
    RepeatLayout="Flow" AutoPostBack="True" 
    onselectedindexchanged="chktopics_SelectedIndexChanged">
   <asp:ListItem Selected="true">All</asp:ListItem>
    <asp:ListItem>Item1</asp:ListItem>
    <asp:ListItem>Item2</asp:ListItem>
    <asp:ListItem>Item 3</asp:ListItem>
    <asp:ListItem>Item 4</asp:ListItem>
    <asp:ListItem>Item 5</asp:ListItem>
</asp:CheckBoxList>

In code behind, you can do this in page_load event, 

chktopics.Items[0].Checked = ture;
