    Hello All,

    I trying to use this code in one my tests, but the second function use to cast the element into Tcontrol is throwing this exception -- Exception has been thrown by the target of an invocation . Any idea what am I doing wrong here?

    ===
    var Element = Manager.Current.ActiveBrowser.WaitForElement(Config.Timeout,
                                                                                                  "id=test");
    return Element .As<T>();
    ===

    Thanks,
    Aakash

    Hello Aakash,

    It is hard to determine what is causing the problem without seeing the full exception and the complete code you are using. Are you trying to use a Generic method? If so, I have tested the following code against the Google starting page and it works as expected.
    public T WaitForElement<T>() where T : ArtOfTest.WebAii.Controls.HtmlControls.HtmlControl, new()
    {
     
        var Element = Manager.Current.ActiveBrowser.WaitForElement(10000, "id=gbqfba");
        return Element.As<T>();
     
    }

    [CodedStep(@"New Coded Step")]
    public void WebTest1_CodedStep()
    {           
        HtmlButton button = WaitForElement<HtmlButton>();
        button.Click(false);
    }

    Please provide more detailed information on the issue you are experiencing, so we can continue troubleshooting.
