Does anyone know of a way of hiding a column in an asp.net listview?

Question

I know you can put <% if %> statements in the ItemTemplate to hide controls but the column is still there. You cannot put <% %> statements into the LayoutTemplate whic

Answer 1

The ListView gives you full control about how the data is rendered to the client. You specify the Layout Template, and give a placeholder which will be where each item is injected.

The output of the below will give you a table, and each item will be a new TR.

Notice the use of runat='server' and visible ='<%# %>'

<asp:ListView ID="ListView1" runat="server" DataSourceID="MyDataSource" ItemPlaceholderID="itemPlaceHolder">
    <LayoutTemplate>
        <table>
            <asp:PlaceHolder ID="itemPlaceHolder" runat="server" />
        </table>
    </LayoutTemplate>
    <ItemTemplate>
        <tr>
            <td runat="server" id="myCol" visible='<%# (bool)Eval("IsSuperCool") %>'>
                <%# Eval("SuperCoolIcon") %>
            </td>
            <td>
                <%# Eval("Name") %>
            </td>
            <td>
                <%# Eval("Age") %>
            </td>
        </tr>
    </ItemTemplate>
</asp:ListView>
