Example for UITestControl.WaitForControlCondition Method checking for WpfText.Text value

Question

Hi
I want to wait until the text value of a WpfText is a certain string. How would that be done using UITestControl.WaitForControlCondition Method when a predicate of the test function must be used and I need to reference the WpfText item I want to check
text value of?
Thanks

Hi RB_IA,
AdrianHHH’s idea for that code is right, he meant that he compiled the code but he did not execute it to verify whether the code can run fine. I think that code should run.
For the code you pasted, yes, the UITestControl parameter is not sent to IsStatusDone method through
 parameters within it directly, but the text is defined outside of IsStutusDone method and it is used in the IsStatusDone method.
For your second doubt, Adrian used this API:
WaitForControlCondition(Predicate<UITestControl>) which accepts a bool parameter as the specific condition instead of this API:
WaitForCondition<T>(T, Predicate<T>).
You can reference this code snippet which is used to
wait till the status text of a control is “Succeeded” or “Failed”.in this blog:How
To: Make playback wait for certain event?
// Define the method to evaluate the condition
private
static
bool IsStatusDoneOrError(UITestControl[] controls)
    WinText statusText = controls[0]
as
WinText;
    WinWindow errorDialog = controls[1]
as
WinWindow;
    return statusText.DisplayText ==
"Succeeded" || errorDialog.Exists;
// In test method, wait till the method evaluates to true
UITestControl.WaitForCondition<UITestControl[]>(new
UITestControl[] { statusText, errorDialog }, IsStatusDoneOrError);
I am not a developer, maybe you can try to write your code like below to compare the text value of the wpf control through WpfText.DisplayText property with the expected text value:
class ParameterisedIsStatusDone
    public
ParameterisedIsStatusDone(string t)
expectedtext = t;
    private
string expectedtext;
    public
bool IsStatusDone(UITestControl control)
WpfText ControlTextVale = control
as WpfText;
return
ControlTextVale.DisplayText ==
expectedtext;
ParameterisedIsStatusDone pisd =
new ParameterisedIsStatusDone("Succeeded");
yourControl.WaitForControlCondition(pisd.IsStatusDone);
You also can reference Victor Zn's solution in that thread.
