Radio Button Patterns in WPF?

I am guessing you have to write a client-side provider (proxy) for the Radio button class. Since this is a .NET/Avalon control, and you need to implement the automation patterns on it, the code will reside in a client-side (meaning a separate DLL) proxy which your test scripts / automation code can then load up and let UIA know where to find the proxy for this Radio button class.

Unfortunately the code samples in the latest SDK don't have a good example of implementing a "pure" client-side proxy (by pure I mean I don't have to modify/edit the code for the custom control class, just implement the proxy in a separate DLL and somehow link these two).

If you search the MSDN docs, you'll find some information (and a very basic ConsoleWindow example for a client-side proxy).

I will have to investigate why that is happening. But in the meantime, if you select View Control Patterns in UI Spy, you will see the patterns that are supported.

In your code, you can use TryGetCurrentPattern rather than IsPatternAvailable.

Thanks for pointing this out.

HI,

I am using the below code to select the radioButton but i am getting the error( given below in red).

It seems that radio button don't support selectionItemPattern.

I am using may CTP.

UIAUTOMATION CODE:

-

AutomationElement alcf = null;

PropertyCondition condscf = new PropertyCondition(AutomationElement.NameProperty, "radiosel"); //?

alcf = AutomationElement.RootElement.FindFirst(TreeScope.Children, condscf);

if (alcf == null)

Console.WriteLine("Failed to find radiosel window");

else

Console.WriteLine("Found radiosel window");

alcf.SetFocus();

Condition cccf = new PropertyCondition(AutomationElement.AutomationIdProperty, "radioButton1", PropertyConditionFlags.IgnoreCase);

AutomationElement clcf = null;

clcf = alcf.FindFirst(TreeScope.Element | TreeScope.Children, cccf);

if (clcf == null)

Console.WriteLine("Can't able to find --> radioButton1");

else

Console.WriteLine("find --> radiobutton1");

SelectionItemPattern ipcf;

ipcf = clcf.GetCurrentPattern(SelectionItemPattern.Pattern) as SelectionItemPattern;

ipcf.Select();

-

ERROR:
