AFAIK, the Bookmark control can't be customized to store bookmarks at server side. But likely you could get the sources and tweak them for your need. ... View more

Silverlight doesn't support the IMultiValue converter. But please check the relevant article below, maybe it will give you some workaround ideas: http://csharperimage.jeremylikness.com/2009/07/imultivalueconverter-with-silverlight.html ... View more

Jared is right. You can just set 'ShowOnlyVisibleLayers' to true. Note however that the user will no more be able to turn on a layer using the legend since the non visible layers are not displayed in the legend. ... View more

I tweaked the PieChart sample in order to get column charts. Result here. ... View more

What I was asked is : 1. Remove the root element usaid_layers so it will show more data to the left Looks like you need to use LayerItemsMode="Flat" so the main layer will not show up. Note : if for any reason this option is not ok for you and that you need something between 'Flat' and 'Tree', you'll nee to do it by code on event Legend.Refreshed. 2. shrink the spaces from one layerItem to another in the legend tab. You can change the LegendItemTemplate (for example by using negative margins). ... View more

I was playing around with this and I notice that after initialization the VisibleLayers collection is still null (which would explain the error). It is not until a method call has been made to SeLayerVisisibility has been made that this collection is actually available. This explains the behavior you see because clicking a layer on the Legend will make a call internally to SetLayerVisibility. I checked this on both 3.0 and 2.4 and see the same behavior. Personally, I would consider this a bug. By convention, a null VisibleLayers means that the default layer visibilities are used. So you should take care of the null case in your code and get the visibility from the LayerInfo DefaultVisibility. Or simply use GetLayerVisibility which is doing the job for you. i.e. bool isVisible = westTexas.GetLayerVisibility(layerIds); instead of bool isVisible = westTexas.VisibleLayers.Contains(layerIds); ...

Could you give more infos about what you mean by 'do full screen selection in graphic layer'? ... View more

In particular becuase now have to do update each time the resolution changes. See this thread for a possible workaround to avoid the Update(). Else as gigemboy mentionned, you'll get the best performances by using a DynamicMapServiceLayer or even better with a TiledMapServiceLayer (images cached at the server side). ... View more

I don't see something wrong in your code:confused:. Is it working well when you zoom in to show a few points only? ... View more

Want something like point clustering, but we have line data that may be a significant data payload and display processing, and want something like clustering to increase efficiency/performance. The clustering is only working for points (i.e not working for lines). Please send starting point, or even point us to other optimization options for lines and polygons. The only standard way I know to optimize the payload for lines or polygons is by setting MaxAllowableOffset which can strongly reduce the size of the transferred data. Note : another obvious way is to use DynamicMapServiceLayer or TiledMapServiceLayer but I guess it's not applicable in your context. ... View more

You should be able to create a custom dynamic layer by subclassing the DynamicMapServiceLayer class and implementing GetURL by using the NOKIA REST API. Though note that I never tested that and that I didn't check the NOKIA licence agreement. ... View more

but i want to change this zoom, where can i edit ?? I don't understand well the question. The argument to the method ZoomTo is the envelope you ned to zoom to. To change it you need to change the way that envelope is initialized (for example by changing the size). ... View more

If you see graphics that don't have any corresponding row in the table, it might mean that you set 'AutoSave' to false. In this case you have to call SaveEdits in order to save your graphics as rows in the database. ... View more

If you are using a DynamicMapService layer or a tiled layer. This has to be done at the server side. But I am not sure if this can be done easily (probably by using cartographic rules). You may get better answers by posting the question on the server forum. If it's a feature layer, you should be able to do it by code at the client side. For each graphic that overlaps another graphic(tolerance to define), you can change the symbols of these graphics. Unfortunately I don't see any sample doing that. ... View more
