zoom to feature from Featuredat grid after query execution

ManojrajTeli — Fri, 09 Dec 2011 10:43:35 GMT

I ma binding the result to graphic layer and from graphics layer i am publishing the attributes into feature data grid but the zoom to selected feature is not working at all

Below is the code

 void queryTask_ExecuteCompleted(object sender, ESRI.ArcGIS.Client.Tasks.QueryEventArgs e)
        {
            GraphicsLayer graphicsLayer = Map.Layers["MyGraphicsLayer"] as GraphicsLayer;
            graphicsLayer.ClearGraphics();
            FeatureSet featureset = e.FeatureSet;
            featureset.SpatialReference = Map.SpatialReference;
            if (featureset != null && featureset.Features.Count>0 )
            {
                foreach (Graphic resultfeature in featureset.Features)
                {
                     switch (featureset.GeometryType.ToString())
                     {
                         case "Polygon":
                             resultfeature.Symbol = LayoutRoot.Resources["DefaultQueryFillSymbol"] as ESRI.ArcGIS.Client.Symbols.Symbol;
                             break;
                         case "Polyline":
                             resultfeature.Symbol = LayoutRoot.Resources["DefaultQueryLineSymbol"] as ESRI.ArcGIS.Client.Symbols.Symbol;
                             break;
                         case "Point":
                             resultfeature.Symbol = LayoutRoot.Resources["DefaultQueryMarkerSymbol"] as ESRI.ArcGIS.Client.Symbols.Symbol;
                             break;
                     }
                     graphicsLayer.Graphics.Add(resultfeature);
                     System.Windows.Data.Binding bind = new System.Windows.Data.Binding();
                     bind.ElementName = "Map";
                     bind.Path = new PropertyPath("Layers.[MyGraphicsLayer]");
                     MyDataGrid.SetBinding(ESRI.ArcGIS.Client.Toolkit.FeatureDataGrid.GraphicsLayerProperty, bind);
                     MyDataGrid.UpdateLayout();
                }
            }
}




private void MyDataGrid_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            DataGrid datagrid = sender as DataGrid;
            int selectedindex = datagrid.SelectedIndex;
            if (selectedindex > -1)
            {
                FindResult findresult = (FindResult)MyDataGrid.SelectedItem;
                Graphic graphic = findresult.Feature;
                switch (graphic.Attributes["Shape"].ToString())
                {
                    case "Polygon":
                        graphic.Symbol = LayoutRoot.Resources["DefaultQueryFillSymbol"] as ESRI.ArcGIS.Client.Symbols.Symbol;
                        break;
                    case "Polyline":
                        graphic.Symbol = LayoutRoot.Resources["DefaultQueryLineSymbol"] as ESRI.ArcGIS.Client.Symbols.Symbol;
                        break;
                    case "Point":
                        graphic.Symbol = LayoutRoot.Resources["DefaultQueryMarkerSymbol"] as ESRI.ArcGIS.Client.Symbols.Symbol;
                        break;

                }
                GraphicsLayer graphicsLayer = Map.Layers["MyGraphicsLayer"] as GraphicsLayer;
                graphicsLayer.ClearGraphics();
                graphicsLayer.Graphics.Add(graphic);
            }
}

also i am assigning symbology in graphics layer directly. I want to assign the symbology when i am selecting record from feature data grid and zoom to feature.Thank you in advance.I tried example from find and query from esri blog still not working..

Did you look at this thread ?
There is code to extend the 'Find' sample in order to get zoom working.
