Get the Report →Create Dynamic Harvest Grids Using the Infragistics XamDataGrid
Learn how you can connect Harvest 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 API Driver for ADO.NET, you gain the capability to construct interactive grids, charts, and various other visual elements while directly accessing real-time data from Harvest 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 Harvest
The last step in building our WPG App with a dynamic DataGrid is connecting to and querying live Harvest 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.API; using System.Data;
Finally, add the code to connect to Harvest and query using the text from the TextBox to the Click event handler.
Start by setting the Profile connection property to the location of the Harvest Profile on disk (e.g. C:\profiles\Harvest.apip). Next, set the ProfileSettings connection property to the connection string for Harvest (see below).
Harvest API Profile Settings
To authenticate to Harvest, you can use either Token authentication or the OAuth standard. Use Basic authentication to connect to your own data. Use OAuth to allow other users to connect to their data.
Using Token Authentication
To use Token Authentication, set the APIKey to your Harvest Personal Access Token in the ProfileSettings connection property. In addition to APIKey, set your AccountId in ProfileSettings to connect.
Using OAuth Authentication
First, register an OAuth2 application with Harvest. The application can be created from the "Developers" section of Harvest ID.
After setting the following connection properties, you are ready to connect:
- ProfileSettings: Set your AccountId in ProfileSettings.
- AuthScheme: Set this to OAuth.
- OAuthClientId: Set this to the client ID that you specified in your app settings.
- OAuthClientSecret: Set this to the client secret that you specified in your app settings.
- CallbackURL: Set this to the Redirect URI that you specified in your app settings.
- InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to manage how the driver obtains and refreshes the OAuthAccessToken.
private void Button_Click(object sender, RoutedEventArgs e) { //connecting to Harvest string connString = "Profile=C:\profiles\Harvest.apip;ProfileSettings='APIKey=my_personal_key;AccountId=_your_account_id';"; using (var conn = new APIConnection(connString)) { //using the query from the TextBox var dataAdapter = new APIDataAdapter(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 Harvest data in our XamDataGrid. When you click "Execute," the app connects to Harvest and submits the SQL query through the CData ADO.NET Provider.

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