Public Methods
| Name | Description | |
|---|---|---|
 | CancelAsync | Cancels a pending asynchronous operation. (Inherited from ESRI.ArcGIS.Client.Tasks.TaskBase) |
| Execute | Executes a query against an ArcGIS Server map layer. The result is returned as a FeatureSet. A FeatureSet contains an array of Graphic features, which can be added to the map using GraphicsLayer.Graphics.Add. This array will not be populated if no results are found. |
| ExecuteAsync | Executes a query against an ArcGIS Server map layer. The result is returned as a FeatureSet. If the query is successful, the ExecuteCompleted event is raised with the result. A FeatureSet contains an array of Graphic features, which can be added to the map using Map.graphics.add(). This array will not be populated if no results are found. |
| ExecuteCount | Executes a query against an ArcGIS Server map layer and counts the results. |
| ExecuteCountAsync | Executes a query against an ArcGIS Server map layer and counts the results. If the query is successful, the ExecuteCountCompleted event is raised with the result. |
| ExecuteCountTaskAsync | Overloaded. Executes a query against an ArcGIS Server map layer and counts the results. If the query is successful, the task returns an integer result. Otherwise, the Task.Exception is set. |
| ExecuteRelationshipQuery | Executes a query to a obtain addtional data from another layer/table based on a relationship defined in the service meta data. |
| ExecuteRelationshipQueryAsync | Executes a query to a obtain addtional data from another layer/table based on a relationship defined in the service meta data. |
| ExecuteRelationshipQueryTaskAsync | Overloaded. Executes a query to a obtain addtional data from another layer/table based on a relationship defined in the service meta data. |
| ExecuteTaskAsync | Overloaded. Executes a query against an ArcGIS Server map layer. If the query is successful, the task returns a QueryResult. Otherwise, the Task.Exception is set. |
| GetRequestUri | Gets the request URI. |
Protected Methods
| Name | Description | |
|---|---|---|
 | OnPropertyChanged | Called when a task result related property value has changed. These properties are named, or end with, "LastResult". E.g. QueryTask exposes the "LastResult" property, and GeometryService has a "BufferLastResult" property. (Inherited from ESRI.ArcGIS.Client.Tasks.TaskBase) |
Public Events
| Name | Description | |
|---|---|---|
 | ExecuteCompleted | Occurs when the query completes. |
| ExecuteCountCompleted | Occurs when the count query completes. |
| ExecuteRelationshipQueryCompleted | Occurs when the query completes. |
| Failed | Occurs when the query completes. (Inherited from ESRI.ArcGIS.Client.Tasks.TaskBase) |
| PropertyChanged | Occurs when a property value changes. (Inherited from ESRI.ArcGIS.Client.Tasks.TaskBase) |
