Learn how you can connect Parquet 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 ADO.NET Provider for Parquet, you gain the capability to construct interactive grids, charts, and various other visual elements while directly accessing real-time data from Parquet 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.
![Adding a TextBox and Button to the App.](../articles/ado-infragistics-datagrid-1.png)
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.
![Adding the XamDataGrid to the App.](../articles/ado-infragistics-datagrid-2.png)
Arrange the component on the designer so that it is below the TextBox & Button and linked to the boundaries of the app.
![XamDataGrid Placement.](../articles/ado-infragistics-datagrid-3.png)
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 Parquet
The last step in building our WPG App with a dynamic DataGrid is connecting to and querying live Parquet data. First add a reference to the CData ADO.NET Provider to the project (typically found in C:\Program Files\CData[product_name]\lib).
![Adding the CData ADO.NET Provider as a Reference (Salesforce is shown.)](../articles/ado-infragistics-datagrid-4.png)
Next, add the Provider to the namespace, along with the standard Data library:
using System.Data.CData.Parquet; using System.Data;
Finally, add the code to connect to Parquet and query using the text from the TextBox to the Click event handler.
Connect to your local Parquet file(s) by setting the URI connection property to the location of the Parquet file.
private void Button_Click(object sender, RoutedEventArgs e) { //connecting to Parquet string connString = "URI=C:/folder/table.parquet;"; using (var conn = new ParquetConnection(connString)) { //using the query from the TextBox var dataAdapter = new ParquetDataAdapter(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 Parquet data in our XamDataGrid. When you click "Execute," the app connects to Parquet and submits the SQL query through the CData ADO.NET Provider.
![Querying Parquet Data](../articles/ado-infragistics-datagrid-5.png)
Live Parquet data is displayed in the grid.
![Displying Parquet Data (Salesforce is shown)](../articles/ado-infragistics-datagrid-6.png)
Group the data by dragging and dropping a column name into the header.
![Grouping Parquet Data (Salesforce is shown)](../articles/ado-infragistics-datagrid-7.png)
As you add groupings and filters, the underlying SQL query is submitted directly to Parquet, making it possible to drill down into live Parquet data to find only the specific information you need.
