The following works and displays the users User Name as a placeholder in the textbox but I can't figure out how to put the word "Username: " before it so that it reads.. Username: John

<asp:TextBox ID="txtMessage" style="margin-top:-8px;" runat="server" Placeholder='<%# Eval("UserName") %>' TextMode="MultiLine" Rows="2" Columns="34"></asp:TextBox>

I tried this..

<asp:TextBox ID="txtMessage" style="margin-top:-8px;" runat="server" Placeholder='"Username: " & <%# Eval("UserName") %>' TextMode="MultiLine" Rows="2" Columns="34"></asp:TextBox>
