Add to Selection option for Query task

Is it possible for me to "add to selection" for the query task?

Thanks.

Could you define what you mean by this? Query task is not a selection tool. It's meant for querying data on the server.

I am using the spatial query sample to bind a QueryTask result to a datagrid (see below). I would like to add to or combine the query results instead of clearing it each time.

Thank you.

' Bind data grid to query results
Dim resultFeaturesBinding As New Binding(("LastResult.Features"))
resultFeaturesBinding.Source = QueryTask

In this case, you can no more take advantage of the existing collection 'QueryTask.LastResults.Features'.

You have to manage yourself a collection of graphics.
When you get the result of a query, depending on your need, you can append/replace/combine/clear the collection.
