Hello,

problably not the first to ask this but can't find any info.

thanks

CodeBehind :

   Page.IsValid

ASpx : 

document.getElementById
('<%# valSum.ClientID%>').styles.display != "none"

I assume you mean how to write a test with LTAF to verify if a validator is showing or not. The easiest way to do this is to call the IsVisible() method that hangs off the HtmlElement. Here is a sample test that is included in our download that illustrates this:

// Navigate to the login page
        HtmlPage page = new HtmlPage("Login.aspx");

        // Verify validators are not visible
        Assert.IsFalse(page.Elements.Find("UserNameRequired").IsVisible());
        Assert.IsFalse(page.Elements.Find("PasswordRequired").IsVisible());
        
        // Click the login button (do not wait for postback)
        page.Elements.Find("LoginButton").Click();

        // Verify validators are now visible
        Assert.IsTrue(page.Elements.Find("UserNameRequired").IsVisible());
        Assert.IsTrue(page.Elements.Find("PasswordRequired").IsVisible());

Thank you both!
