Create Dynamic QuickBooks Online Grids Using the Infragistics XamDataGrid

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 QuickBooks Online, you gain the capability to construct interactive grids, charts, and various other visual elements while directly accessing real-time data from QuickBooks Online 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 QuickBooks Online

The last step in building our WPG App with a dynamic DataGrid is connecting to and querying live QuickBooks Online 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.QuickBooksOnline;
using System.Data;

Finally, add the code to connect to QuickBooks Online and query using the text from the TextBox to the Click event handler.

QuickBooks Online uses the OAuth authentication standard. OAuth requires the authenticating user to log in through the browser. To authenticate using OAuth, you can use the embedded OAuthClientId, OAuthClientSecret, and CallbackURL or you can obtain your own by registering an app with Intuit. Additionally, if you want to connect to sandbox data, set UseSandbox to true.

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 QuickBooks Online
  string connString = "";
  using (var conn = new QuickBooksOnlineConnection(connString))
  {
    //using the query from the TextBox
    var dataAdapter = new QuickBooksOnlineDataAdapter(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 QuickBooks Online data in our XamDataGrid. When you click "Execute," the app connects to QuickBooks Online and submits the SQL query through the CData ADO.NET Provider.

Live QuickBooks Online 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 QuickBooks Online, making it possible to drill down into live QuickBooks Online data to find only the specific information you need.
