Get the Report →Create Dynamic XML Grids Using the Infragistics XamDataGrid
Learn how you can connect XML to Infragistics XamDataGrid to build dynamic grids.
Using Infragistics WPF UI controls, you can build contemporary applications reminiscent of Microsoft Office for both desktop and touch-based devices. When coupled with the CData ADO.NET Provider for XML, you gain the capability to construct interactive grids, charts, and various other visual elements while directly accessing real-time data from XML data. This article will guide you through the process of creating a dynamic grid within Visual Studio using the Infragistics XamDataGrid control.
You will need to install the Infragistics WPF UI components to continue. Download a free trial here: https://www.infragistics.com/products/wpf.
Create a WPF Project
Open VisualStudio and create a new WPF project.
Add a TextBox for passing a SQL query to the CData ADO.NET Provider and a Button for executing the query.
The XAML at this stage is as follows:
< Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:local="clr-namespace:CDataXamDataGridGroupingListApp" xmlns:igWPF="http://schemas.infragistics.com/xaml/wpf" x:Class="CDataXamDataGridGroupingListApp.MainWindow" mc:Ignorable="d" Title="MainWindow" Height="450" Width="800"> < Grid> < TextBox x:Name="textBox" HorizontalAlignment="Left" Height="44" TextWrapping="Wrap" Text="TextBox" VerticalAlignment="Top" Width="682" Margin="10,10,0,0"/> < Button x:Name="button" Content="Execute" HorizontalAlignment="Left" Margin="697,10,0,0" VerticalAlignment="Top" Width="85" Height="44"/> < /Grid> < /Window>
Add and Configure a XamDataGrid
After adding the initial controls, add a XamDataGrid to the App. The component will appear in the Visual Studio toolbox.
Arrange the component on the designer so that it is below the TextBox & Button and linked to the boundaries of the app.
Once the XamDataGrid is placed, edit the XAML to set the XamDataGrid DataSource attribute to "{Binding}" and set the FieldSettings AllowRecordFiltering and AllowSummaries attributes to "true." Next, add an empty method as the Click event handler for the Button component. The XAML at this stage is as follows:
< Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:local="clr-namespace:CDataXamDataGridGroupingListApp" xmlns:igWPF="http://schemas.infragistics.com/xaml/wpf" x:Class="CDataXamDataGridGroupingListApp.MainWindow" mc:Ignorable="d" Title="MainWindow" Height="450" Width="800"> < Grid> < TextBox x:Name="textBox" HorizontalAlignment="Left" Height="44" TextWrapping="Wrap" Text="TextBox" VerticalAlignment="Top" Width="682" Margin="10,10,0,0"/> < Button x:Name="button" Content="Execute" HorizontalAlignment="Left" Margin="697,10,0,0" VerticalAlignment="Top" Width="85" Click="Button_Click" Height="44"/> < igWPF:XamDataGrid Margin="10,59,10,10" DataSource="{Binding}"> < igWPF:XamDataGrid.FieldSettings> < igWPF:FieldSettings AllowSummaries="True" AllowRecordFiltering="True"/> < /igWPF:XamDataGrid.FieldSettings> < /igWPF:XamDataGrid> < /Grid> < /Window>
Connect to and Query XML
The last step in building our WPG App with a dynamic DataGrid is connecting to and querying live XML data. First add a reference to the CData ADO.NET Provider to the project (typically found in C:\Program Files\CData[product_name]\lib).
Next, add the Provider to the namespace, along with the standard Data library:
using System.Data.CData.XML; using System.Data;
Finally, add the code to connect to XML and query using the text from the TextBox to the Click event handler.
See the Getting Started chapter in the data provider documentation to authenticate to your data source: The data provider models XML APIs as bidirectional database tables and XML files as read-only views (local files, files stored on popular cloud services, and FTP servers). The major authentication schemes are supported, including HTTP Basic, Digest, NTLM, OAuth, and FTP. See the Getting Started chapter in the data provider documentation for authentication guides.
After setting the URI and providing any authentication values, set DataModel to more closely match the data representation to the structure of your data.
The DataModel property is the controlling property over how your data is represented into tables and toggles the following basic configurations.
- Document (default): Model a top-level, document view of your XML data. The data provider returns nested elements as aggregates of data.
- FlattenedDocuments: Implicitly join nested documents and their parents into a single table.
- Relational: Return individual, related tables from hierarchical data. The tables contain a primary key and a foreign key that links to the parent document.
See the Modeling XML Data chapter for more information on configuring the relational representation. You will also find the sample data used in the following examples. The data includes entries for people, the cars they own, and various maintenance services performed on those cars.
private void Button_Click(object sender, RoutedEventArgs e) { //connecting to XML string connString = "URI=C:/people.xml;DataModel=Relational;"; using (var conn = new XMLConnection(connString)) { //using the query from the TextBox var dataAdapter = new XMLDataAdapter(textBox.Text, conn); var table = new DataTable(); dataAdapter.Fill(table); //passing the DataRowCollection to the DataContext // for use in the XamDataGrid this.DataContext = table.Rows; } }
Run the Application
With the app fully configured, we are ready to display XML data in our XamDataGrid. When you click "Execute," the app connects to XML and submits the SQL query through the CData ADO.NET Provider.
Live XML data is displayed in the grid.
Group the data by dragging and dropping a column name into the header.
As you add groupings and filters, the underlying SQL query is submitted directly to XML, making it possible to drill down into live XML data to find only the specific information you need.
