You can use the ParamByName property to access a stored parameter by name. In addition, you can use the Parameters.Items property to access all parameters stored in the collection.

BeginUpdate/EndUpdate and Batch Parameter Changes
Every time you modify a parameter stored within the Parameters collection, the State property value is updated and the TdxDashboardControl component redraws content to reflect the change. Enclose multiple parameter changes between Parameters.BeginUpdate and Parameters.EndUpdate procedure calls to avoid UI flickering due to excessive redraw operations and improve performance.
