Use of WebServiceTextSearchProvider: exception

[Dean]

For Windows Phone, I am following the documentation example for using a WebServiceTextSearchProvider class but am getting a NullReferenceException during this call:

 

autoCompleteBox.InitializeSuggestionsProvider(this.webServiceProvider);

 

My webServiceProvider variable is of course a valid object, and the InputChanged event is set up too.

 

The sample code is pretty simple so cannot see what is wrong, unless there is some accompanying properties needed on the control itself in Xaml. I have removed the FilterMode and ItemsSource without luck - these were initially still set, but it throws either way.

Hi Dean,

I have prepared sample application demonstrating how the desired functionality can be achieved. Please have a look at the attached project and let us know if this helps.

Your sample is for Windows Phone 8 - not for Windows Phone Universal. The WebServiceAutoCompleteProvider is not used for Universal, it is instead the WebServiceTextSearchProvider.

 

So this does not help.

Hello Dean,

I have modified the project for Windows Universal. Please excuse me for the misunderstanding.

OK, this runs fine but mine is throwing  - I will try to find what I am doing differently, thanks!
