Property Value

Type Description

A collection ob objects implementing the IParameter interface.


Use the Parameters property to specify dashboard parameter settings.


The following example shows how to filter a custom SQL query by changing a parameter value in the DashboardViewer.CustomParameters event handler.

In this example, the custIDQueryParameter query parameter is included in a WHERE clause of a custom SQL query. The custIDQueryParameter parameter is also bound to the hidden custIDDashboardParameter dashboard parameter. The value of this parameter is changed at runtime by handling the DashboardViewer.CustomParameters event which is raised before the DashboardViewer sends a query to a database.

View Example

using DevExpress.DashboardCommon;
using System.Linq;

namespace Dashboard_CustomParameters_Win {
    public partial class Form1 : DevExpress.XtraEditors.XtraForm {
        public Form1() {

        private void dashboardViewer1_CustomParameters(object sender, CustomParametersEventArgs e) {
            var custIDParameter = e.Parameters.FirstOrDefault(p => p.Name == "custIDDashboardParameter");
            if (custIDParameter != null) {
                custIDParameter.Value = "AROUT";
