public:

public System.Collections.Specialized.IOrderedDictionary ParameterValues { get; }

member this.ParameterValues : System.Collections.Specialized.IOrderedDictionary

Public ReadOnly Property ParameterValues As IOrderedDictionary

Property Value

IOrderedDictionary

An IOrderedDictionary of Parameter objects.

Remarks

The ObjectDataSourceFilteringEventArgs class is used to pass data to the Filtering event handler of the ObjectDataSource object. The ParameterValues property provides access to the filter parameter values before the filtering operation is performed.

Important

You should validate any filter parameter value that you receive from the client. The runtime simply substitutes the parameter value into the filter expression and applies it to the DataView object that is returned by the Select method. If you are using the FilterExpression property as a security measure to limit the number of items that are returned, you must validate the parameter values before the filtering occurs.
