Hello! Could you please help me to fix the following issue when I call _radCombobox.ToggleDropDown():


The control was found, was expanded and then this exception was thrown:


Message: 
    System.TimeoutException : Wait for condition has timed out
  Stack Trace: 
    Server stack trace: 
    WaitSync.CheckResult(WaitSync wait, String extraExceptionInfo, Object target)
    WaitSync.For[T](Predicate`1 predicate, T target, Boolean invertCondition, Int32 timeout, WaitResultType errorResultType)
    WaitSync.For[T](Predicate`1 predicate, T target, Boolean invertCondition, Int32 timeout)
    VisualWait.ForVisible(Int32 timeout)
    VisualWait.ForNoMotion(Int32 initialWait, Int32 motionCheckInterval, Int32 timeout)
    RadComboBox.WaitDropDownAnimation(Int32 millis)
    RadComboBox.ToggleDropDown()

Here is the combobox (as a part of UserControl):


<telerik:RadComboBox  x:Name="CmbAddressType" Grid.Row="1" Grid.Column="3" Grid.ColumnSpan="3">
          <TextBlock>LG Nexus 5X</TextBlock>
          <TextBlock>Huawai Nexus 6P</TextBlock>
          <TextBlock>iPhone 6S</TextBlock>
          <TextBlock>iPhone 6S Plus</TextBlock>
          <TextBlock>Microsoft Lumia 950</TextBlock>
        </telerik:RadComboBox>

Application: WPF

Testing Framework: Progress Telerik Test Studio 2021.3(213.11.3.0)

Hello Vitaly,

I tried reproducing your scenario with our latest full release version (2022.1.117) of Progress Telerik UI for WPF. Unfortunately, I was unable to reach the same result you described. Could you share which version you are using?

Is it possible for you to also share the test code itself? Or if you would rather, could you modify the attached project so that it throws the same exception you are getting?
