如果带有Eval（）或DataBinder.Eval（）的ListView中的语句？

Question

I have a listview control on an .aspx page. Inside this list view i want to check "Type" property which comes from database. here is the example code :

 <ItemTemplate>
         <%# if(Convert.ToInt32(DataBinder.Eval(Container.DataItem,"Type")) == 0){ %>
            <tr class="item">
                <td>
                    <%# Convert.ToDateTime(Eval("WorkDate")).ToShortDateString() %>
                </td>
                <td style="text-align: center;">
                    <%# Eval("SkillName") %>
                </td>
             </tr>
         <%# } else if (Convert.ToInt32(DataBinder.Eval(Container.DataItem,"Type")) == 1) {%>
             <tr class="item">
                <td colspan="2">
                    <strong><%# Convert.ToDateTime(Eval("WorkDate")).ToShortDateString() %></strong>
                </td>
             </tr>
          <% } %>
  </ItemTemplate>

As a last resort i tried to user DataBinder.Eval() but i get the exception "Expected class, delegate, enum, interface, or struct". What can i be doing wrong? Writing a function in code-behind isn't an option for me. Is there a way to achieve this?

Here is the full code, made fancy and short.

 <ItemTemplate>
         <tr class="item">
            <td colspan="<%# Eval(Container.DataItem,"Type")) == 0 ? 1:2%>">
                <strong><%# Convert.ToDateTime(Eval("WorkDate")).ToShortDateString() %></strong>
            </td>
             <td style="text-align: center;" visible="<%# Eval(Container.DataItem,"Type")) == 1>">
                <%# Eval("SkillName") %>
            </td>
        </tr>
 </ItemTemplate>

Untested, as I don't have Visual Studio available at the moment, but since HtmlTableRow has a Visible property, the following should work:

<tr class="item" runat="server" Visible='<%# Convert.ToInt32(Eval("Type")) == 0 %>'>
    ...
</tr>

yes you will have to do some client side scripting though... I would suggest jquery..

you would basically loop through all of the rows in jquery and based on the data in the row you would be able to change the innerhtml of the row object based on the ".item" selector to determine whether it should be in one format or the other.
