DynamicListLookUpSettings Class

Provides the look-up editor settings for dashboard parameters that are bound to a data source.

Namespace: DevExpress.DashboardCommon

Assembly: DevExpress.Dashboard.v21.2.Core.dll


public class DynamicListLookUpSettings :


Use the DashboardParameter.LookUpSettings property to specify the look-up editor settings of the parameter.


The following example demonstrates how to create a new dashboard parameter and pass it to a dashboard item filter string.

In this example, the dashboard data source contains two queries - the SalesPerson query is used for data visualization while the Categories query provides values for the dashboard parameter.

After the dashboard parameter is created, it is passed to a dashboard item’s filter strings. So, the dashboard displays data according to the selected values.

View Example

using DevExpress.XtraEditors;
using DevExpress.DashboardCommon;

namespace Dashboard_Parameters {
    public partial class Form1 : XtraForm {
        public Form1() {
            Dashboard dashboard = new Dashboard();

            // Obtain dashboard items and specify identifiers for data items.
            GridDashboardItem grid = (GridDashboardItem)dashboard.Items[0];
            PieDashboardItem pie = (PieDashboardItem)dashboard.Items[1];  
            ((GridDimensionColumn)grid.Columns[0]).Dimension.UniqueId = "categoryColumn";
            pie.SeriesDimensions[0].UniqueId = "categorySeries";

            // Obtain the dashboard data source used to provide parameter values.
            DashboardSqlDataSource parameterDataSource = 

            // Create a new parameter that obtains its values from the Categories query.
            DynamicListLookUpSettings settings = new DynamicListLookUpSettings();
            settings.DataSource = parameterDataSource;
            settings.DataMember = "Categories";
            settings.ValueMember = "CategoryName";
            DashboardParameter parameter = new DashboardParameter("categoryParameter", 
                typeof(string), "Beverages", "Select categories:", true, settings);
            // Enable multi-selection for the created parameter.
            parameter.AllowMultiselect = true;

            // Add the created parameter to a collection of dashboard parameters.

            // Include the created parameter in filter strings as an operand value.
            grid.FilterString = "categoryColumn in (?categoryParameter)";
            pie.FilterString = "categorySeries in (?categoryParameter)";

            dashboardViewer1.Dashboard = dashboard;
