I am working with .NET. So I will share what I am doing and maybe that will help :-) 1. Build Selection XML Note: searchString is your query (ID==1 || ID==2). var mgMapName = requestParams["mapName"]; var mgSessionId = requestParams["sessionId"]; // Initialize the web-tier. var realPath = this.Request.ServerVariables["APPL_PHYSICAL_PATH"]; var configPath = realPath + "..\\webconfig.ini"; MapGuideApi.MgInitializeWebTier(configPath); // Connect to the site. var userInfo = new MgUserInformation(mgSessionId); var conn = new MgSiteConnection(); conn.Open(userInfo); // get the map var map = new MgMap(conn); map.Open(mgMapName); // Perform any necessary transforms on the layer name or ids var mapObjects = TransformInputLayer(requestParams["objectTypes"].Split(','), requestParams["objectIds"].Split(',')); // Select the objects on the map var layers = map.GetLayers(); var selection = new MgSelection(map); foreach (var layer in layers) { var searchString = new StringBuilder(); // Build out the search expression for the map layer foreach (var mapObject in mapObjects.Where(rec => rec.LayerName == layer.Name)) { if (searchString.Length > 0) { searchString.Append(" OR "); } searchString.AppendFormat("Id = '{0}'", mapObject.ObjectId); } // Execte the search on the layer if (searchString.Length > 0) { var displayIdQuery = new MgFeatureQueryOptions(); displayIdQuery.SetFilter(searchString.ToString()); var featureReader = layer.SelectFeatures(displayIdQuery); selection.AddFeatures(layer, featureReader, AppSettings.MgSelectionFilterSize); featureReader.Close(); featureReader.Dispose(); } } var selectionXml = selection.ToXml(); map.Dispose(); 2. Now the fun part I am working on right now - pass your selection to Fusion. I used to have AJAX Viewer and I used following logic: I have some aspx page (SetMapSelection.aspx) SetMapSelection.aspx: <head runat="server"> <title>Set Map Selection Page</title> <script type="text/javascript" language="javascript" src="http://localhost/mapguide/fusion/layers/MapGuide/MapGuideViewerApi.js";></script> <script type="text/javascript"> // Emit the following function and assocate it with the onLoad event for // the page so that it gets executed when this page loads in the browser. // The function calls the SetSelectionXML method on the Viewer Frame, // which updates the current selection on the viewer and the server. function OnPageLoad() { var selectionXml = document.getElementById("hfSelectionXml").getAttribute("value"); parent.SetSelectionXML(selectionXml); parent.ExecuteMapAction(10); parent.ExecuteMapAction(99); } </script> </head> <body onload="OnPageLoad()"> <form id="formM5Logic" runat="server"> <div> <asp:TextBox ID="hfSelectionXml" runat="server"></asp:TextBox> <asp:HiddenField ID="HiddenFieldM5Logic" runat="server"></asp:HiddenField> </div> </form> </body> SetMapSelection.aspx.cs: protected void Page_Load(object sender, EventArgs e) { // Disable the client side cache this.Response.Cache.SetCacheability(HttpCacheability.NoCache); // Write to session which page is loaded, this is used by the context help to determine the // approproiate help page to load. this.Session.Add(SessionStateBase.HELP_PAGE_REFERENCE, this.Request.Path); // Get the input parameters into the selection var requestParams = this.Request.HttpMethod == "GET" ? this.Request.QueryString : this.Request.Form; var mgMapName = requestParams["mapName"]; var mgSessionId = requestParams["sessionId"]; // Initialize the web-tier. var realPath = this.Request.ServerVariables["APPL_PHYSICAL_PATH"]; var configPath = realPath + "..\\webconfig.ini"; MapGuideApi.MgInitializeWebTier(configPath); // Connect to the site. var userInfo = new MgUserInformation(mgSessionId); var conn = new MgSiteConnection(); conn.Open(userInfo); // get the map var map = new MgMap(conn); map.Open(mgMapName); // Perform any necessary transforms on the layer name or ids var mapObjects = TransformInputLayer(requestParams["objectTypes"].Split(','), requestParams["objectIds"].Split(',')); // Select the objects on the map var layers = map.GetLayers(); var selection = new MgSelection(map); foreach (var layer in layers) { var searchString = new StringBuilder(); // Build out the search expression for the map layer foreach (var mapObject in mapObjects.Where(rec => rec.LayerName == layer.Name)) { if (searchString.Length > 0) { searchString.Append(" OR "); } searchString.AppendFormat("Id = '{0}'", mapObject.ObjectId); } // Execte the search on the layer if (searchString.Length > 0) { var displayIdQuery = new MgFeatureQueryOptions(); displayIdQuery.SetFilter(searchString.ToString()); var featureReader = layer.SelectFeatures(displayIdQuery); selection.AddFeatures(layer, featureReader, AppSettings.MgSelectionFilterSize); featureReader.Close(); featureReader.Dispose(); } } var selectionXml = selection.ToXml(); map.Dispose(); this.hfSelectionXml.Text = selectionXml; } So as you can see - Page_Load builds selection XML and OnPageLoad passes it to AJAX Viewer frame for further processing. What I am puzzled with is to how to get a reference to Fusion, so I can pass my selection to Fusion. Something like this: function OnPageLoad() { var selectionXml = document.getElementById("hfSelectionXml").getAttribute("value"); var vf = top.document.getElementById('frmMap'); vf.document.forms[0].GetFusionMapWidget.setSelection(selectionXml, true); } Note: In my app I have 2 iframes - Map Viewer and Application frame. frmMap is Map Viewer frame: <iframe name="frmDefault" id="frmDefault" class="frameBoxGeneral" frameborder="0" src="Pages/Loading.aspx"> </iframe> <iframe name="frmMap" id="frmMap" src="<%= AppSettings.MgServicesUrl %>/fusion/templates/mapguide/standard/index.html" class="frameBoxMap" frameborder="0"></iframe> View message @ http://osgeo-org.1803224.n2.nabble.com/How-to-use-setselection-in-fusion-tp5001965p5009766.html To unsubscribe from How to use setselection in fusion?, click here. -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/How-to-use-setselection-in-fusion-tp5001965p5012703.html Sent from the MapGuide Users mailing list archive at Nabble.com.
