Create Dynamic IBM Cloud Data Engine Grids Using the Infragistics XamDataGrid



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

The last step in building our WPG App with a dynamic DataGrid is connecting to and querying live IBM Cloud Data Engine data. First add a reference to the CData ADO.NET Provider to the project (typically found in C:\Program Files\CData\CData ADO.NET Provider for IBM Cloud Data Engine\lib).

Next, add the Provider to the namespace, along with the standard Data library:

using System.Data.CData.IBMCloudDataEngine;
using System.Data;

Finally, add the code to connect to IBM Cloud Data Engine and query using the text from the TextBox to the Click event handler.

IBM Cloud Data Engine uses the OAuth and HMAC authentication standards. See the "Getting Started" chapter of the help documentation for a guide to using OAuth.

private void Button_Click(object sender, RoutedEventArgs e)
{
  //connecting to IBM Cloud Data Engine
  string connString = "Api Key=MyAPIKey;Instance CRN=myInstanceCRN;Region=myRegion;Schema=mySchema;OAuth Client Id=myOAuthClientId;OAuth Client Secret=myOAuthClientSecret;";
  using (var conn = new IBMCloudDataEngineConnection(connString))
  {
    //using the query from the TextBox
    var dataAdapter = new IBMCloudDataEngineDataAdapter(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 IBM Cloud Data Engine data in our XamDataGrid. When you click "Execute," the app connects to IBM Cloud Data Engine and submits the SQL query through the CData ADO.NET Provider.

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