I am using the Comparevalidator to check if the value selected in the dropdownlist is "Select", but this does not work, follow the code. 

<asp:DropDownList ID="ddlIdPisSt" runat="server" DataSourceID="sdsIdPisSt" DataTextField="Descricao"  
    DataValueField="Id" AppendDataBoundItems="True" Width="790px">
    <asp:ListItem Value="">Selecione</asp:ListItem>
</asp:DropDownList>                 
<asp:CompareValidator ID="CompareValidator1" runat="server" ControlToValidate="ddlIdPisSt" Display="Dynamic" 
    ErrorMessage=" * " Operator="NotEqual" ValueToCompare="" ForeColor = "Red">
</asp:CompareValidator>

What I’m doing wrong. Can someone help me.

Friend, try to use the Requiredvalidator, because the "Select" does not contain value and the Requiredvalidator will take.

Try and tell us if it worked.

    Thanks to the tip, Rboschini, to use the Requiredvalidator, just add the property Initialvalue=" " that solved my problem. Thanks.
