... about layer isinitialized properties

MarcoRosa

hi friends,
hi have to add on map a dynamic map service layer ....

<esri:ArcGISDynamicMapServiceLayer ID="dinamico"
                    Url="http://myserver/ArcGIS/rest/services/test/MapServer" InitializationFailed="ArcGISDynamicMapServiceLayer_InitializationFailed"/>

happens that .... when i stop the services and start the application .... InitializationFailed is fired correctly.
Buot later .... if i do

   private void button1_Click(object sender, RoutedEventArgs e)
        {
            for (int i = 0; i < MyMap.Layers.Count; i++)
            {
                MessageBox.Show(MyMap.Layers.ID+" - "+ MyMap.Layers.IsInitialized);
            }
        }

isinitialize properties is true and layer is added on map but not visible ....... This is strange because this value could be false bacause the layer is not initialized ( and then could not be added on map  )
it's true ?

What is my error ?

thank you as usual
ciao GD

What do you mean?

As Jennifer mentionned, this property only tells you that the layer has attempted to initialize.

To know if the initialization failed, you can use the property InitializationFailure, if it's not null, it means that the initialization failed.

So the possible combinations are:
   - IsInitialized = false : the layer is not initialized yet
   - IsInitialized = true and InitializationFailure = null : the layer has initialized correctly
   - IsInitialized = true and InitializationFailure != null : initialization is over but there was a failure

Hi dbroux,

  Thanks for replying, IsInitialized is not working means that even if the .mxd doc. consists of layers whose datasource is not set, then it shows true, thats why I have written its not working, I want a solution that will give me an answer that the mapservice which I am loading consists of layers without datasource, I found the answer in

ArcGISDynamicMapService lyr = sender as ArcGISDynamicMapService();
if lyr.layers == null then it gives indication that .mxd doc. consists of layers whose datasource is not set, if it is not null then it gives indication that .mxd doc. consists of layers whose datasources are set
