The following code snippet shows how to create a dashboard parameter with dynamic look-up values in code. Use the Dashboard.Parameters property of Dashboard to access a collection of dashboard parameters.

C#

DynamicListLookUpSettings settings = new DynamicListLookUpSettings();
settings.DataSource = sqlDataSource;
settings.DataMember = "Categories";
settings.ValueMember = "CategoryID";
settings.DisplayMember = "CategoryName";
settings.SortOrder = DimensionSortOrder.Descending;
DashboardParameter parameter3 = new DashboardParameter("Parameter3", typeof(string), "1", "Select a category:", true, settings);

VB.NET

Dim settings As New DynamicListLookUpSettings()
settings.DataSource = sqlDataSource
settings.DataMember = "Categories"
settings.ValueMember = "CategoryID"
settings.DisplayMember = "CategoryName"
settings.SortOrder = DimensionSortOrder.Descending
Dim parameter3 As New DashboardParameter("Parameter3", GetType(String), "1", "Select a category:", True, settings)
