Canceling queryTask

[ThaoNguyen]

Hi,
Is there a document on how to cancel an excuting QueryTask properly?
I know that there is method CancelAsync(), but I want to know more if additional steps need to be done to have this done properly.

Thanks!

You can use https, is this for token-secured service? QueryTask, like the other tasks have a Token property if you want to set this explicitly. Or you can also enable IdentityManager with SignInDialog or your own control that lets you set username/password for the secured service.

To use IdentityManager and SignInDialog, you can refer to the Security samples here: ArcGIS API for Silverlight - Interactive Samples | ArcGIS for Developers (should be similar to WPF).

Or if you have a token string, set QueryTask.Token property. If you have to go through a proxy, there's also ProxyUrl.

This doc might help : ArcGIS Runtime SDK for WPF

thank you for the speey reply

the odd thing is that a URL (http://services.arcgis.com/pmcEyn9tLWCoX7Dm/ArcGIS/rest/services/TimeZoneFeatures/FeatureServer/0) has either been changed or the security protocol has changed so I need to update the http with https yet when I change the URL in code and step through the code the URL does not reflect the new https but retains the http....frustrating.
