Property Value

Type	Description
List<IParameter>	A collection of dashboard parameters.

Remarks

When a dashboard parameter in the collection changes its value, it leads to the cache key recreation. If dashboard parameters have no effect on the resulting dataset, associated data requests are unnecessary. Use the DashboardConfigurator.DataSourceCacheKeyCreated or ASPxDashboard.DataSourceCacheKeyCreated event to exclude the dashboard parameter collection from the cache key. This way you can optimize data access performance.

The following code snippet handles the DataSourceCacheKeyCreated event to exclude dashboard parameter collection from cache keys for the ASP.NET Core Dashboard Control:

configurator.DataSourceCacheKeyCreated += (sender, args) => {
    args.Key.Parameters.Clear();
};
