Query task result failed to update after features created or delete in Silverlight Ap

XiujuZhou — Thu, 24 Feb 2011 13:35:57 GMT

I have silverlight application which can create new or delete feature using ArcGIS API 2. after a feature created or deleted, I do query by WCR_NUM (see below, a WCR_NUM contain one more features), the result of the featureSet still includes the deleted feature or not includes new created feature, which means the query result is not updated. Please help!

QueryTask queryTask;
ESRI.ArcGIS.Client.Tasks.Query query;
queryTask = new QueryTask("http://mapserver2.pwe.pserv.coh.gov/ArcGIS/rest/services/WCRPolygon/MapServer/0"); queryTask.ExecuteCompleted += QueryTask_ExecuteCompleted;
queryTask.Failed += QueryTask_Failed;
query = new ESRI.ArcGIS.Client.Tasks.Query();
query.OutFields.Add("*");
query.Where = "WCR_NUM='" + WCRNUM + "' and STATUS='Active'"; query.ReturnGeometry = true;
queryTask.ExecuteAsync(query);

Did you set 'DisableClientcaching' to true?

Where to set it up? I don't know where it is.

The QueryTask class has a property 'DisableClientCaching' that can be set to true to prevent the request from being looded from the browser's cache.
