Findtask datagrid display

gabrielvazquez — Thu, 25 Aug 2011 17:17:05 GMT

I am using a findtask to query a layer. Similiar to the this example http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#Find . I am also trying to export all of the query result fields to datagrid, as is done in the example. However, I am not sure how to export all of the data field results to the datagrid using the findtask.

I can do it easily with a querytask, similar to this example http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#QueryWithoutMap. However I'm not sure how to get all of layer data from a findtask to populate the featuredatagrid.

I have the Findtask results bound to the datagrid, however the datagrid just comes up blank. Not sure if this has to do with the fact that I am not defining any output fields, as is done with a querytask "query.OutFields.Add("*");" or if there is some other specific syntax I am missing.

I thought it would be something as simple as using datagrid.Itemsource = args.FindResults; However that does not work also, if someone has any experience with data grids, and importing FindTask results, please let me know.

If you want to use FeatureDataGrid to display results of your tasks, you can use GraphicsLayer to add/remove Graphics in your ExecuteCompleted event handler and be sure to set Map and GraphicsLayer property in XAML, as seen below:

  <esri:FeatureDataGrid Grid.Row="2" x:Name="MyDataGrid"
    Map="{Binding ElementName=MyMap}"
    GraphicsLayer="{Binding ElementName=MyMap, Path=Layers.[MyGraphicsLayer]}" />

Jennifer,
Thank you very much. Such a simple fix. I forget that I could enable an ESRI FeatureDataGrid in the XAML. I was using an windows data grid and trying to apply it within the C# code.

That helped.
