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 HubDB, you gain the capability to construct interactive grids, charts, and various other visual elements while directly accessing real-time data from HubDB 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.
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.
π 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>
After adding the initial controls, add a XamDataGrid to the App. The component will appear in the Visual Studio toolbox.
π 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.
π 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>
The last step in building our WPG App with a dynamic DataGrid is connecting to and querying live HubDB data. First add a reference to the CData ADO.NET Provider to the project (typically found in C:\Program Files\CData[product_name]\lib).
π 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.HubDB; using System.Data;
Finally, add the code to connect to HubDB and query using the text from the TextBox to the Click event handler.
There are two authentication methods available for connecting to HubDB data source: OAuth Authentication with a public HubSpot application and authentication with a Private application token.
AuthScheme must be set to "OAuth" in all OAuth flows. Be sure to review the Help documentation for the required connection properties for you specific authentication needs (desktop applications, web applications, and headless machines).
Follow the steps below to register an application and obtain the OAuth client credentials:
Under Scopes, select any scopes you need for your application's intended functionality.
A minimum of the following scopes is required to access tables:
To connect using a HubSpot private application token, set the AuthScheme property to "PrivateApp."
You can generate a private application token by following the steps below:
To connect, set PrivateAppToken to the private application token you retrieved.
private void Button_Click(object sender, RoutedEventArgs e)
{
//connecting to HubDB
string connString = "AuthScheme=OAuth;OAuthClientID=MyOAuthClientID;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:33333;InitiateOAuth=GETANDREFRESH;";
using (var conn = new HubDBConnection(connString))
{
//using the query from the TextBox
var dataAdapter = new HubDBDataAdapter(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;
}
}
With the app fully configured, we are ready to display HubDB data in our XamDataGrid. When you click "Execute," the app connects to HubDB and submits the SQL query through the CData ADO.NET Provider.
π Querying HubDB DataLive HubDB data is displayed in the grid.
π Displying HubDB Data (Salesforce is shown)Group the data by dragging and dropping a column name into the header.
π Grouping HubDB Data (Salesforce is shown)As you add groupings and filters, the underlying SQL query is submitted directly to HubDB, making it possible to drill down into live HubDB data to find only the specific information you need.
π Grouped and filtered HubDB Data (Salesforce is shown)At this point, you have created a dynamic WPF App with access to live HubDB data. For more information, visit the CData ADO.NET Provider page.
