Create Dynamic SAS Data Sets Grids Using the Infragistics XamDataGrid



Use the CData ADO.NET Provider for SAS Data Sets and the 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 SAS Data Sets, you gain the capability to construct interactive grids, charts, and various other visual elements while directly accessing real-time data from SAS Data Sets 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 SAS Data Sets

The last step in building our WPG App with a dynamic DataGrid is connecting to and querying live SAS Data Sets 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.SASDataSets;
using System.Data;

Finally, add the code to connect to SAS Data Sets and query using the text from the TextBox to the Click event handler.

Set the following connection properties to connect to your SAS DataSet files:

Connecting to Local Files

  • Set the Connection Type to "Local." Local files support SELECT, INSERT, and DELETE commands.
  • Set the URI to a folder containing SAS files, e.g. C:\PATH\TO\FOLDER\.

Connecting to Cloud-Hosted SAS DataSet Files

While the driver is capable of pulling data from SAS DataSet files hosted on a variety of cloud data stores, INSERT, UPDATE, and DELETE are not supported outside of local files in this driver.

Set the Connection Type to the service hosting your SAS DataSet files. A unique prefix at the beginning of the URI connection property is used to identify the cloud data store and the remainder of the path is a relative path to the desired folder (one table per file) or single file (a single table). For more information, refer to the Getting Started section of the Help documentation.

private void Button_Click(object sender, RoutedEventArgs e)
{
  //connecting to SAS Data Sets
  string connString = "URI=C:/myfolder;";
  using (var conn = new SASDataSetsConnection(connString))
  {
    //using the query from the TextBox
    var dataAdapter = new SASDataSetsDataAdapter(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 SAS Data Sets data in our XamDataGrid. When you click "Execute," the app connects to SAS Data Sets and submits the SQL query through the CData ADO.NET Provider.

Live SAS Data Sets 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 SAS Data Sets, making it possible to drill down into live SAS Data Sets data to find only the specific information you need.
