Exception on set text and button is not click

Hello,

I’m can’t to use FlaUi, need help please.

First, I try set a text to a TextBox and showme a “System.InvalidOperationException”.

var pass = window.FindFirstDescendant(cf => cf.ByName("ds_pass"))?.AsTextBox();
pass.Text = "SUPER";

Second, I try click a button, but not happens:

window.FindFirstDescendant(cf => cf.ByName("OK"))?.AsButton().Click();

Thanks!!

What kind of control is your textbox (WPF, WinForms, some library control)? As alternative, you could try using Enter instead of .Text.

This question is searchable by Google and I come across it while working on my problem, hope it helps others. I have WPF app, there’s a textbox and button bound to a command. When you enter something into textbox, the button become enable. But, I had a flaky test related to it. It worked fine on local machine, but on CI I got timeout error while waiting for the button to enable:

System.TimeoutException : Timeout occurred in retry Stack Trace: at FlaUI.Core.Tools.Retry.While[T](Func1 retryMethod, Func2 checkMethod, Nullable1 timeout, Nullable1 interval, Boolean throwOnTimeout, Boolean ignoreException, String timeoutMessage, Boolean lastValueOnTimeout, T defaultOnTimeout) at FlaUI.Core.Tools.Retry.WhileFalse(Func1 checkMethod, Nullable1 timeout, Nullable1 interval, Boolean throwOnTimeout, Boolean ignoreException, String timeoutMessage) at FlaUI.Core.AutomationElements.AutomationElementExtensions.WaitUntilEnabled[T](T self, Nullable1 timeout)

I used textBox.Text to set the value, and apparently it didn’t produce needed events. textBox.Enter() solved the problem, thank you Roemer!
