Create Dynamic Hugging Face Grids Using the Infragistics XamDataGrid

Learn how you can connect Hugging Face 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 Hugging Face 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.

πŸ‘ Adding a TextBox and Button to the App.

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.

πŸ‘ Adding the XamDataGrid to the App.

Arrange the component on the designer so that it is below the TextBox & Button and linked to the boundaries of the app.

πŸ‘ XamDataGrid Placement.

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 Hugging Face

The last step in building our WPG App with a dynamic DataGrid is connecting to and querying live Hugging Face data. First add a reference to the CData ADO.NET Provider to the project (typically found in C:\Program Files\CData[product_name]\lib).

πŸ‘ Adding the CData ADO.NET Provider as a Reference (Salesforce is shown.)

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 Hugging Face and query using the text from the TextBox to the Click event handler.

HuggingFace Hub uses token-based authentication to enable access to its API. The API provides access to machine learning models, datasets, spaces, papers, and other resources on the HuggingFace Hub platform.

Using API Key Authentication

To authenticate to HuggingFace Hub, you will need to provide an API Key (Access Token). To obtain your access token:

  1. Log in to your HuggingFace account at https://huggingface.co
  2. Navigate to Settings > Access Tokens
  3. Click "New token" to create a new access token
  4. Select the appropriate permissions (read or write)
  5. Copy the token value

After obtaining your access token, set the following connection properties:

  • AuthScheme: Set this to APIKey.
  • APIKey: Set this to your HuggingFace access token.

Example connection string

Profile=C:\profiles\HuggingFace.apip;ProfileSettings='APIKey=hf_xxxxxxxxxxxxxxxxxxxx';
private void Button_Click(object sender, RoutedEventArgs e)
{
 //connecting to Hugging Face
 string connString = "Profile=C:\profiles\HuggingFace.apip;ProfileSettings='APIKey=hf_xxxxxxxxxxxxxxxxxxxx';";
 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 Hugging Face data in our XamDataGrid. When you click "Execute," the app connects to Hugging Face and submits the SQL query through the CData ADO.NET Provider.

πŸ‘ Querying Hugging Face Data

Live Hugging Face data is displayed in the grid.

πŸ‘ Displying Hugging Face Data (Salesforce is shown)

Group the data by dragging and dropping a column name into the header.

πŸ‘ Grouping Hugging Face Data (Salesforce is shown)

As you add groupings and filters, the underlying SQL query is submitted directly to Hugging Face, making it possible to drill down into live Hugging Face data to find only the specific information you need.
