Dynamically load rows in a horizontal datagrid with the query results.

Summary

Instructions provided explain how to update a datagrid dynamically with the query results, without hard-coding attribute names, similar to the Attribute Query Sample.

Procedure

• The idea is to bind the DataGrid's ItemSource property with query/identify result attributes:
  
  

  Code:
  QueryDetailsDataGrid.ItemsSource = selectedFeature.Attributes;

  
  
  Here QueryDetailsDataGrid is the DataGrid's x:Name and selectedFeature is the first feature of the resulting FeatureSet of the query task (refer to the Attribute Query Sample for details).
• Populate the columns at runtime from the results of the query:
  
  

  Code:
  var dictionary1 = selectedFeature.Attributes as IDictionary;
  foreach (DictionaryEntry pair in dictionary1)
  { 
     var str = "Attributes[" + pair.Key.ToString() + "]";
     QueryDetailsDataGrid.Columns.Add(new DataGridTextColumn
     {
       Header = pair.Key,
       Binding = new Binding(str)
     });
  }

  
  
• Make sure that the XAML for the datagrid has no columns, because columns will be populated at runtime.
  
  

  Code:
   <slData:DataGrid x:Name="QueryDetailsDataGrid" AutoGenerateColumns="True" Background="White"/>
