Try this:

JavaScript

function fnValidate()
{
    if(document.getElementById('<%=ddlTest.ClientID%>').selectedIndex == 0)
    {
        alert("Please select from drop down");
        return false;
    }
    return true;
}

Hi ,
You could also try this one

XML

<div>
<asp:Button ID="Button2" runat="server" Text="Button" ValidationGroup="ss" />
<asp:DropDownList ID="DropDownList1" runat="server" AppendDataBoundItems="True"
    ValidationGroup="ss">
<asp:ListItem Text="---select---" Value="0" ></asp:ListItem>
<asp:ListItem Text="---test---" Value="1" ></asp:ListItem>

</asp:DropDownList>
<asp:CompareValidator ID="CompareValidator1" runat="server"
    ControlToValidate="DropDownList1" Display="Dynamic"
    ErrorMessage="CompareValidator" ForeColor="#FF3300" Operator="GreaterThan"
    SetFocusOnError="True" ValueToCompare="0" ValidationGroup="ss"></asp:CompareValidator>
    </div>

Best Regards

Solution 1

Can I suggest an Alternative?

Why not try RequiredFieldValidator? Provide an empty value for the first element and direct your validator to the Dropdownlist6.
