See http://msdn.microsoft.com/en-us/library/cc189078(VS.95).aspx Youtube is probably not an option. They use Flash and not Silverlight. In some cases they use h.264 video streams, so if you can manage to figure out what stream is uses, technically you can point to this. However the stream endpoint constantly changes, specically to keep people from doing this. You are probably better off generating some WMV files and host them yourself. The above link should give you what you need to know. ... View more

That looks like a 3rd party control based on the Popup control. ... View more

I would probably create a new type of button class (inherits from Button), and give it a boolean property to say whether its in "help mode". Then bind this property to help checkbox. Override the Click method, and raise the "HelpClick" event instead of the Click event. Alternatively you could have the button pop up the help window, and have a help description property on the button as well. ... View more

There is no "custom" cursors in Silverlight, other than the few predefined ones. Instead set the Map.Cursor=Cursors.None, and use the MouseMove event to move a usercontrol that represents the cursor around, so it looks like its a cursor that follows the map. Make sure you also set IsHitTestVisible on the cursor, so it doesn't block mouse interaction with the map. ... View more

Use a QueryTask instead of calling Update() and add the new features returned from the query to the layer. You will need some type of way to only query data that has changed (ie a timestamp column or similar) if you want to really optimize it. Note that if you are hitting a FeatureServer, you would want to set AutoSave to false, or you will risk adding the features multiple times. ... View more

Apparently we had some issues with the download servers, but I've been told it has been resolved. Let me know if anyone still experiences this. ... View more

To show all features in the datagrid, you need to have the features populated in the datagrid. Features that are not in the map extent are not rendered to the map, so I'm not sure that you are really gaining any performance improvement by constantly changing the contents of the layer - on the contrary that sounds more expensive. ...

Correct. MapTips relies on the mouse entering/leaving a graphic. If the layer and thus the graphic is not visible, the maptip cannot "trigger". ... View more

Before you spend any more time on this, I think you should be aware of the terms of service for Yahoo Maps: http://info.yahoo.com/guidelines/us/yahoo/ydn/ydn-3955.html "With the Yahoo! Maps APIs, you may NOT re-use Yahoo! Maps imagery without the API..." Google Maps has a similar restriction. Basically you cannot use their image tiles for anything other than their own API (if you could we would already have provided these datasources for you 🙂 Bing maps is the only datasource I know where there's an option for using their tiles outside their own API. ...

Considering you have a white background, I would expect a White page. Does it turn white when you remove the map control? ... View more

That's interesting... The browser event is only used in two cases: 1) If you are running on a Mac 2) If you are using FireFox/Chrome/Safari and running the plugin in windowless mode. Are you in one of these scenarios? Btw. this hasn't changed since v1.2. ... View more

You will need to publish the MXD to ArcGIS Server, and then use the REST service this creates to display the map. You cannot load an MXD directly. ... View more

Yes this should work. Did you set the spatial reference on the point you created? ... View more

At the root element of you maptip, set the following hide delay property : <Grid esri:GraphicsLayer.MapTipHideDelay="0:0:0.5"> ... This will give plenty of time for the user to move the mouse over to the maptip before it closes. ... View more

Visual Studio 2010 and Blend SDK should be installed prior to the ArcGIS Silverlight API. ... View more
