中继器数据绑定错误

Question

Half a day spent on this one...

On a page, I have two repeaters like so:

<% if (String.IsNullOrEmpty(Request.QueryString["id"])) { %>

    <asp:Repeater ID="auth_items" runat="server">

        <ItemTemplate>
            <a href="/admin/auth.aspx?action=view&amp;id=<%# Eval("id") %>"><%# Security.script(Eval("name").ToString()) %></a><br />
        </ItemTemplate>

    </asp:Repeater>

<% } else { %>    

    <asp:Repeater ID="auth_item" runat="server">

        <ItemTemplate>
        <%# Security.script(Eval("name").ToString()) %>
        </ItemTemplate>

    </asp:Repeater>    

<% } %>

and in code behind:

if (String.IsNullOrEmpty(Request.QueryString["id"]))
    sql = "SELECT * FROM table1 ORDER BY attr1 DESC";
else
{
    id = Security.sql(Request.QueryString["id"]);
    sql = "SELECT * FROM table2 WHERE attr2=" + id;
}

s.OpenConn(sql);

if (String.IsNullOrEmpty(Request.QueryString["id"]))
{
    auth_items.DataSource = s.GetRead();
    auth_items.DataBind();
}
else
{
    auth_item.DataSource = s.GetRead();
    auth_item.DataBind();
}

The problem is that I get 'object reference not set to an instance of an object' on auth_item.DataBind(). First repeater works fine and displays the data, but the second one won't work and instead, throws me an error. I debugged it and DataSource for the second repeater is not null, and sql returns a value.

What seems to be the problem?

Thank you!

Answer 1

table2 doesn't have a name column?
