Gets or sets the expression used to filter which rows are viewed.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
When is not nullptr, the BindingSource passes this property to the underlying list. If you set this property during object initialization, the call will be deferred until after initialization is complete.
To form a filter value, specify the name of a column followed by an operator and a value to filter on. The accepted filter syntax depends on the underlying data source. If the underlying data source is a DataSet, DataTable, or DataView, you can specify Boolean expressions using the syntax documented for the DataColumn::Expression property.
The following example shows how to use the property with a DataView. To run this example, paste the code into a Windows Form and call PopulateDataViewAndFilter from the form's constructor or Load event-handling method. Your form should import the System.Xml and System.IO namespaces.
