how to specify the AttributeFields shown with IdentifyTask

UlfGrimhardt — Wed, 14 Jul 2010 08:49:28 GMT

Hi

With help from the RessourceCenter i implemented a IdentifyTask to my SilverlightApplication. At the Moment the AttributeFields that are identified are shown in a DataGrid. Is it possible to specify the Fields that are shown? At the moment all Fields are Identified and visible, but things like ObjectID and Shape arent really important. How can i specify the shown AttributeFields?

If your graphics are coming from an identify task, you might remove the useless attributes by code by something like:

 
foreach (IdentifyResult identifyResult in args.IdentifyResults)
{
Graphic graphic = identifyResult.Feature;
graphic.Attributes.Remove("Shape");
graphic.Attributes.Remove("ObjectID");
}

Not sure it's the best way, but no other idea:)

Salt17 or dbroux....where do I need to add this code? If I change the foreach loop below I can't get it to work.

  foreach (IdentifyResult result in results)
                {
                    Graphic feature = result.Feature;
                    
                    string title = result.Value.ToString() + " (" + result.LayerName + ")";
                    _dataItems.Add(new DataItem()
                   
                    {
                        Title = title,
                        Data = feature.Attributes
                         
                    });
                    IdentifyComboBox.Items.Add(title);
                }
                IdentifyComboBox.SelectedIndex = 0;
            }
        }

You can remove the fields that you don't want in the service itself. Just go to the properties of each feature class in the service, go to the fields tab and uncheck the fields that you do not need.
