Hi guys,
I know that identify task can perform on the layers in the map service by assign the layer's url, but I am just wondering whether it can also perform on a graphicslayer that I added in the xaml page.
The reason why I want to do this is that the user only wants some of the features in a layer to display. There is a combox used for choosing fiscal year, like 2011 or 2012. If the user choose 2011, then only the features belongs to the 2011 will display on the map. I am thinking to use a query task to implement this part. Then the query results will be added on a graphicslayer.
The other need is to perform identify task on the result features, which is the part that I am concerned. I am not sure whether the identify task could be performed on the graphicslayer.
Any thoughts or ideas are appreciated! Thanks advance!
