Hello Devin,

I am sorry for the troubles with this action. You can try the following workarounds to automate this step.

1. Select the KendoAngularNumericTextBox and enable SimulateRealTyping. Now Test Studio will simulate real desktop keyboard actions as the real user behavior (see simulateRealTyping.png). During the test execution, Test Studio will scroll the element to the top of the page and click in the field. Then it will input the numbers with keyboard actions and not as a plain text.
2. You can use a coded step, like the example below, to make the necessary action. The code below should double click on the element, delete the current content and enter a number using keyboard presses. Before that, you need to add System.Windows.Forms as an assembly to the project and reference it in the coded step.
   

   Pages.KendoAngularDemoApp0.KendoNumerictextboxTag.Wait.ForExists(30000);
   Pages.KendoAngularDemoApp0.KendoNumerictextboxTag.MouseClick(ArtOfTest.WebAii.Core.MouseClickType.LeftDoubleClick, 0, 0, ArtOfTest.Common.OffsetReference.AbsoluteCenter);
   Manager.Desktop.KeyBoard.KeyPress(Keys.Delete);
   Manager.Desktop.KeyBoard.KeyPress(Keys.D3);
   Manager.Desktop.KeyBoard.KeyPress(Keys.D2);

3. You can use the coded approach to simulate the real user behavior and make sure that the element is visible on the page. Please check the code sample below and adjust the Pages element according to your project.
   

   Pages.Overview.FrameExampleBasicUsage.KendoNumerictextboxTag.ScrollToVisible(ArtOfTest.WebAii.Core.ScrollToVisibleType.ElementBottomAtWindowBottom); //scroll the element to the bottom of the page to ensure it is visible
   ActiveBrowser.Window.SetFocus();
   Pages.Overview.FrameExampleBasicUsage.KendoNumerictextboxTag.Focus();
   Pages.Overview.FrameExampleBasicUsage.KendoNumerictextboxTag.MouseClick(); //click on the textbox
   Manager.Desktop.KeyBoard.TypeText("12", 50, 100, true); //send desktop keyboard commands, which simulates real user typing

I hope those suggestions will help you with the automation at hand until we implement a solution for this issue. You can follow the public bug report to get notifications for its progress.

Thank you for you understanding.
