Create Dynamic OpenWeatherMap 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 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 OpenWeatherMap 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.

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.

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

👁 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 OpenWeatherMap

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

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

Using API Key Authentication

To obtain an API key, sign up for a free account at https://openweathermap.org/api and navigate to the API keys section of your dashboard. Copy your API key for use in the connection configuration.

After setting the following connection properties, you are ready to connect:

• AuthScheme: Set this to APIKey.
• APIKey: Set this to your OpenWeatherMap API key.

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

👁 Querying OpenWeatherMap Data

Live OpenWeatherMap data is displayed in the grid.

👁 Displying OpenWeatherMap Data (Salesforce is shown)

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

👁 Grouping OpenWeatherMap Data (Salesforce is shown)

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