<asp:checkboxlist>

[Simon Cheng]

Hi,

For the following form:

<form runat="server">
<asp:checkboxlist id="list" runat="server">
<asp:listitem runat="server" value="Cash" />
<asp:listitem runat="server" value="Check" />
</asp:checkboxlist><br/>
</form>

I get the the attached error message. The same form works with
"asp:radiolist." What am I missing? (This is on W2K3.)

Thanks,
Simon

Try

<asp:checkboxlist id="list" runat="server">
<asp:listitem>Cash</asp:listitem>
<asp:listitem>Check</asp:listitem>
</asp:checkboxlist>

I re-try it today, and now the following works fine for me:

<form runat="server">
<asp:checkboxlist id="list" runat="server">
<asp:listitem runat="server" value="Cash1" />
<asp:listitem runat="server" value="Check1" />
</asp:checkboxlist><br/>
</form>

I have no clue...

Try

<asp:checkboxlist id="list" runat="server">
<asp:listitem>Cash</asp:listitem>
<asp:listitem>Check</asp:listitem>
</asp:checkboxlist>
