ASPxTextBox ErrorText Not Updated on Lost Focus

Question

I got this ASPxTextBox:

<dxe:ASPxTextBox ID="txtFirstName" runat="server">
    <ClientSideEvents LostFocus="function(s, e) {
        if (s.GetText() == '')
        {
            s.SetIsValid(false);
            s.errorText = 'Please enter First Name.';
        }
    }"></ClientSideEvents>
    <ValidationSettings ErrorDisplayMode="ImageWithTooltip">
    </ValidationSettings>
</dxe:ASPxTextBox>

But the errorText displayed isn't what I have set inside the LostFocus event. Instead, the default errorText which is "Invalid value" is displayed in the tool tip.

Any ideas? Thanks

I happen to solve the problem:

        if (s.GetText() == '')
        {
            s.errorText = 'Please enter First Name.';
            s.SetIsValid(false);
        }

Modifying the value of errorText should come first before setting IsValid property of the ASPxTextBox to false.

(I want to laugh at my stupidness! OMG)

Thanks for those who helped. :)
