Can you check whether 'SQL Server SDE View' has a column whose value uniquely identifies each row in the result? Tanu, thanks a lot for that info.  I eventually had figured this problem out, sorry, should have posted back... the problem was just as you said.  The views unique column was set to the Object Id, which in this case was not unique.  I didn't know at the time that you could register a different column as being the unique one, so once I ran the SDE command "sdetable -o alter_reg" to change this, it worked great. So my assumption is that ArcMap uses this unique column, where ArcGIS Server does not. Thanks a lot for the help! ... View more

Thanks for all the info Jennifer! Good to know on number 1 and I got number 3 worked out... Still working on number 2; I am looping through each graphic trying to change it's Symbol.ControlTemplate.  I understand how the VisualStates work, but not real sure how to copy a ControlTemplate and inject a VisualState into it.... also, the Symbol needs a ScaleTransform, how do I inject that? Here are a few things I was trying but don't work:                 DependencyObject symbolDependencyObject = graphic.Symbol.ControlTemplate.LoadContent();                 FrameworkElement symbolFrameworkElement = symbolDependencyObject as FrameworkElement;                 symbolFrameworkElement.RenderTransform = new ScaleTransform(50, 50); //Scaling big initially just to see if scale works                 var storyboard = new Storyboard();                 var doubleAnimation = new DoubleAnimation(50, 1, new Duration(TimeSpan.Zero));                 Storyboard.SetTarget(doubleAnimation, symbolFrameworkElement);                 Storyboard.SetTargetProperty(doubleAnimation, new PropertyPath("RenderTransform.ScaleX"));                 storyboard.Children.Add(doubleAnimation);                 var storyboard2 = new Storyboard();                 var doubleAnimation2 = new DoubleAnimation(1, 50, new Duration(TimeSpan.Zero));                 Storyboard.SetTarget(doubleAnimation2, symbolFrameworkElement);                 Storyboard.SetTargetProperty(doubleAnimation2, new PropertyPath("RenderTransform.ScaleX"));                 storyboard2.Children.Add(doubleAnimation2);                 var stateGroup = new VisualStateGroup { Name = "MouseOverState" };                 stateGroup.States.Add(new VisualState { Name = "MouseOut", Storyboard = storyboard });                 stateGroup.States.Add(new VisualState { Name = "MouseOver", Storyboard = storyboard2 });                 var sgs = VisualStateManager.GetVisualStateGroups(symbolFrameworkElement);                 sgs.Add(stateGroup); I also tried just adding a trigger, but again do not have a ScaleTransform plus it throws this error "After a 'TriggerCollection' is in use (sealed), it cannot be modified.", so guess this is a no go.                 Trigger trigger = new Trigger();                 trigger.Property = FrameworkElement.IsMouseOverProperty;                 trigger.Value = true;                 Setter setter = new Setter();                 setter.Property = ScaleTransform.ScaleXProperty;                 setter.Value = 50;                 trigger.Setters.Add(setter);                 graphic.Symbol.ControlTemplate.Triggers.Add(trigger); Still poking around this code, but any help or ideas would be great!  Thanks! And with number 4, there really isn't anything special with the code; the map is referencing some internal services and some ESRI services.  It has something to do with our network here I think.  When ESRI started using the Amazon cloud, it dynamically routes traffic so services.arcgisonline.com will give different IPs.  Some of these IPs were in our routers block list, after allowing them this hanging of the layers loading went down drastically.  It still happens every once in a while (a lot yesterday though) and I think it now is some issue with our proxy.  I have our network guys looking into it (kind of hard though since it is temperamental).  Anyway, I guess the only question I have is if there is a way to set/control the timeout of a layer?  Maybe I can set it to give up after 15 seconds or something?   So at least other layers can then load. Thanks a ton for all your great help! ... View more

Jennifer, The DataContext on a parent control was indeed set, I changed this around and it works great!  Thanks a lot! ... View more

Update, I lied... MXD Doctor did work! The first time under the treatment options I left the "Transfer all non broken" option checked.  I unchecked this and check all the boxes except for the "VBA Project" one (which I assume strips out the old VBA then) and it works now! Thanks a lot! ... View more

Duncan, Great idea, thanks!  I ran it through the MXD doctor and the fixed map unfortunatly still crashes though :(.  Thanks for the great idea though! ... View more

Hey Shawn, Sorry, I don't have an answer for you... but wanted to report that I am trying to help one of our users solve this exact same problem.  Everytime he double clicks to open ThisDocument it crashes.  Other maps of his he can open it just fine, but just this map crashes every time. ...

Thanks a lot for that example, that is great... I didn't even think to pass the FeatureLayer that way.  I am still having issues with the binding though.  If I do the binding as in your example: <esriPrimitives:SymbolDisplay Symbol="{Binding Converter={StaticResource attributeToSymbolConverter}}" /> It does not bind to the attribute collection, but to the parent UserControl that hosts the ESRI map control... kind of wierd.  I also tried this binding <esriPrimitives:SymbolDisplay Symbol="{Binding /, Converter={StaticResource attributeToSymbolConverter}}" /> And it seems to bind to the first item in the attribute collection, but not the collection itself... I'll keep playing with the bindings, I'm still a bit new to SL/WPF... If you have any ideas though that would be great. Thanks a ton for all the help! ... View more

Jennifer,  Thanks a lot of the reply! Hmm, the FeatureLayer's service does contain a "drawingInfo", It has too right, to get the symbology from the server?  The FeatureLayer's Renderer is NOT null, but each graphic.Symbol is NOT null either... Could you please provide an example on how to set the DataContext to the Graphic (and not the Attributes collection)?  I have tried every binding I could think of but cannot get the graphic... I also made a value converter, if it is even needed, but not sure how to get access to the FeatureLayer in it to call FeatureLayer.GetSymbol(graphic)... but I will worry about that if the above doesn't work. Thank you much and thanks for any more help!!! ... View more

I would try these two items: 1) In the ArcGIS Server Manager, open the "Properties" for your service and go to the "Parameters" tab.  There is an option "Maximum Number of Records Returned by Server"... try making this something like 30,000. 2) In your WPF app, use a clusterer on the FeatureLayer.  See this example: http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#SimpleClusterer Notes: - Now if you do return all 30,000 records when the map loads, it might take 10+ seconds or so, so you might want to show some type of loading bar (and make sure your users are ok with this delay). - Also, if the FeatureLayer.Mode is set to OnDemand, I would set the OnDemandCacheSize to around 30,000 too to prevent trips back to the server. - If you do NOT use the clusterer with this many points, it will likely lock up your application... just too much for the client to render. - And if you do not need any of the benefits of FeatureLayers (MapTips, Clustering, Client Side Filtering, etc), then by all means, just use an ArcGISDynamicMapServiceLayer. - Search both the WPF and Silverlight forums (Silverlight API is practically the same as the WPF), there are other topics on this... Morten, one of the API developers created OnDemandMapTips which are nice to help the initial load time. These are just some of the things I have tried and found, others might have other opinions and ideas�?� Hope this helps a little. ... View more

For FeatureLayers, ArcGIS Server 9.3 only returns 500 features by default and ArcGIS Server 10 only returns 1000.  By chance do you have more features than this?  This might be the issue. If you open the "Properties" for your service and go to the "Parameters" tab on your service there is an option "Maximum Number of Records Returned by Server"... try making this bigger.  Careful though, because returning too many features can slow down or even crash your map. Hope that helps some... ... View more
