Type Default Description

An object implementing the IDashboardDataSource interface that specifies the data source for the dashboard parameter.


You can specify a data source as a source for dashboard parameter values. To provide access to data source values, specify the following options:

UI Settings Description API
Data Source Specifies the data source for the dashboard parameter. DataSource
Data Member Specifies the name of the data member with the parameter values for SQL and Entity Framework data sources. DataMember
Value Member Specifies the name of the data field for the parameter values. ValueMember
Display Member (optional) Specifies the name of the data field displayed in the Dashboard Parameters dialog as a value description. DisplayMember
Sort By (optional) Specifies the data member used to sort parameter values. SortByMember
Sort Order (optional) Specifies the sort order. SortOrder


You cannot use an OLAP data source as the data source for a dashboard parameter.

To access the collection of existing dashboard data sources, use the Dashboard.DataSources property.

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.

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);
