server tag is not well formed with trying to assign am attribute to a text field

[Steven]

the following works but when i try to assign the eval to the text field, I get server tag is not formed correctly. Any idea how to get it to work?

<telerik:RadListBox ID="AssignedFieldsGV" runat="server" Width="375px" Height="500px" AllowTransferOnDoubleClick="true"  ItemDataBound ="AssignedFieldsGV_ItemDataBound "

    SelectionMode="Multiple"  EnableDragAndDrop="true"  AutoPostBack="true"  

    >

   <HeaderTemplate>

         Assigned Fields               

   </HeaderTemplate>

   <ItemTemplate>

        <table>

            <tr>

                <td style="width:125px;">   <asp:Label ID="Label1" runat="server"  Text='<%# DataBinder.Eval(Container, "Text")%>' /></td>

                <td style="width:255px;">  <asp:TextBox ID="Label2" runat="server"   />    <%# DataBinder.Eval(Container, "Attributes['DisplayName']") %>      </td>

            </tr>

        </table>

    </ItemTemplate>

 

</telerik:RadListBox>

for label2, when I try to assign it as Text I get server tag is not well formed, any idea whats wrong?

<telerik:RadListBox ID="AssignedFieldsGV" runat="server" Width="375px" Height="500px" AllowTransferOnDoubleClick="true" ItemDataBound ="AssignedFieldsGV_ItemDataBound "
SelectionMode="Multiple" EnableDragAndDrop="true" AutoPostBack="true"
>
<HeaderTemplate>
Assigned Fields
</HeaderTemplate>
<ItemTemplate>
<table>
<tr>
<td style="width:125px;"> <asp:Label ID="Label1" runat="server" Text='<%# DataBinder.Eval(Container, "Text")%>' /></td>
<td style="width:255px;"> <asp:TextBox ID="Label2" runat="server" Text=' <%# DataBinder.Eval(Container, "Attributes['DisplayName']") %>' /> </td>
</tr>
</table>
</ItemTemplate>

</telerik:RadListBox>

Hi Steven,

The problem is that when you put the expression inside the TextBox's Text property,  you are using 3 sets of quotes. To distinguish the innermost set, the one around DisplayName, from the others, just escape them with \". In other words, your expression should look like this:

<asp:TextBox ID="Label2" runat="server" Text=' <%# DataBinder.Eval(Container, "Attributes[\"DisplayName\"]") %>' />

thanks for the fix. I tried all sorts of combinations escaping stuff but didnt change the escaped single quotes to double quotes
