<div>
Try this<br />

<pre><code id="code-20-38360748-1">&lt;asp:TextBox ID=&quot;txtActionStartDate&quot; CssClass=&quot;actionStartDate&lt;%=DataBinder.Eval(Container.DataItem, 'ID')%&gt;&quot; runat=&quot;server&quot;&gt;&lt;/asp:TextBox&gt;</code></pre>
</div>


Try this


<asp:TextBox ID="txtActionStartDate" CssClass="actionStartDate<%=DataBinder.Eval(Container.DataItem, 'ID')%>" runat="server"></asp:TextBox>

<div>
thats actually rendering the code as text:<br />
&nbsp;class=&quot;actionStartDate&lt;%=D<wbr />ataBinder.<wbr />Eval(Conta<wbr />iner.DataI<wbr />tem, 'ID')%&gt;&quot; type=&quot;text&quot;
</div>


thats actually rendering the code as text:
 class="actionStartDate<%=DataBinder.Eval(Container.DataItem, 'ID')%>" type="text"

<div>
got my own solution in the end.

Hi,<br />
<br />
I have a textbox within a repeater:<br />

<pre><code id="code-10-27851392-1">&lt;asp:TextBox ID=&quot;txtActionStartDate&quot; CssClass=&quot;actionStartDate&lt;%#DataBinder.Eval(Container.DataItem, 'ID')%&gt;&quot; runat=&quot;server&quot;&gt;&lt;/asp:TextBox&gt;</code></pre>
<br />
As you can see I am trying to set a css class containing a dynamic value.<br />
<br />
I'm getting:<br />
The server tag is not well formed.<br />
<br />
How can I do this?
