Create Dynamic Splunk 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 ADO.NET Provider for Splunk, you gain the capability to construct interactive grids, charts, and various other visual elements while directly accessing real-time data from Splunk 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 Splunk

The last step in building our WPG App with a dynamic DataGrid is connecting to and querying live Splunk 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.Splunk;
using System.Data;

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

To authenticate requests, set the , , and properties to valid Splunk credentials. The port on which the requests are made to Splunk is port 8089.

The data provider uses plain-text authentication by default, since the data provider attempts to negotiate TLS/SSL with the server.

If you need to manually configure TLS/SSL, see Getting Started -> Advanced Settings in the data provider help documentation.

private void Button_Click(object sender, RoutedEventArgs e)
{
 //connecting to Splunk
 string connString = "user=MyUserName;password=MyPassword;URL=MyURL;InitiateOAuth=GETANDREFRESH;";
 using (var conn = new SplunkConnection(connString))
 {
 //using the query from the TextBox
 var dataAdapter = new SplunkDataAdapter(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 Splunk data in our XamDataGrid. When you click "Execute," the app connects to Splunk and submits the SQL query through the CData ADO.NET Provider.

👁 Querying Splunk Data

Live Splunk data is displayed in the grid.

👁 Displying Splunk Data (Salesforce is shown)

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

👁 Grouping Splunk Data (Salesforce is shown)

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