Property Value

The parameters that are used for creating the projection.

Remarks

Like the Select method of the ObjectQuery<T> class, parameters can be passed to the projection that is defined by the Select property. The SelectParameters property of the EntityDataSource control specifies a ParameterCollection that contains the parameters to supply to the SELECT statement of the query. The SelectParameters property uses named arguments to refer to the parameters that are specified in the string that is supplied to the Select property.

If the SelectParameters property is not set, no parameter substitution is made. All the parameter names in the SELECT statement, prefixed by the "@" symbol, must have a matching name in the ParameterCollection. Null values are not allowed for parameters in a ParameterCollection.
