How to: Display the Underlying Data for a Dashboard Item
- 2 minutes to read
This example demonstrates how to display the underlying data when an end-user double-clicks a dashboard item.
Handle the DashboardItem.DoubleClick event. Call the e.GetUnderlyingData method to retrieve records from the dashboard item’s data source. Invoke a form with the Grid control that displays the data.
using DevExpress.DashboardCommon;
using DevExpress.DashboardWin;
using DevExpress.Utils;
using DevExpress.XtraEditors;
using System.Windows.Forms;
namespace Dashboard_UnderlyingDataWin
{
public partial class Form1 : XtraForm
{
public Form1()
{
InitializeComponent();
}
private void dashboardViewer1_DashboardItemDoubleClick(object sender,
DashboardItemMouseActionEventArgs e)
{
XtraForm form = new XtraForm
{
Text = "Underlying Data"
};
DashboardUnderlyingDataSet underlyingData = e.GetUnderlyingData();
if (underlyingData != null && underlyingData.RowCount > 0)
{
DevExpress.XtraGrid.GridControl grid = new DevExpress.XtraGrid.GridControl
{
Parent = form,
Dock = DockStyle.Fill,
DataSource = underlyingData,
};
}
else
{
LabelControl lbl = new LabelControl
{
Text = "No Data",
Parent = form,
};
lbl.AutoSizeMode = LabelAutoSizeMode.None;
lbl.Appearance.TextOptions.HAlignment = HorzAlignment.Center;
lbl.Appearance.TextOptions.VAlignment = VertAlignment.Center;
lbl.Dock = DockStyle.Fill;
}
form.ShowDialog();
form.Dispose();
}
}
}
