Create Dynamic LinkedIn Grids Using the Infragistics XamDataGrid

Use the CData ADO.NET Provider for LinkedIn and the Infragistics XamDataGrid to build dynamic grids.

The Infragistics WPF UI controls allow you to build modern, Microsoft Office-inspired apps for desktop and touch devices. When paired with the CData ADO.NET Provider for LinkedIn, you can build dynamic grids, charts, and other visualizations with access to live LinkedIn data. This article walks through creating a dynamic grid in 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 LinkedIn

The last step in building our WPG App with a dynamic DataGrid is connecting to and querying live LinkedIn 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 LinkedIn\lib).

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

using System.Data.CData.LinkedIn;
using System.Data;

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

LinkedIn uses the OAuth 2 authentication standard. You will need to obtain the OAuthClientId and OAuthClientSecret by registering an app with LinkedIn. For more information refer to our authentication guide.
private void Button_Click(object sender, RoutedEventArgs e)
{
  //connecting to LinkedIn
  string connString = "OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:portNumber;CompanyId=XXXXXXX";
  using (var conn = new LinkedInConnection(connString))
  {
    //using the query from the TextBox
    var dataAdapter = new LinkedInDataAdapter(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 LinkedIn data in our XamDataGrid. When you click "Execute," the app connects to LinkedIn and submits the SQL query through the CData ADO.NET Provider.

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