'Declaration Public Property DataSourceFilterExpression As FilterExpressionBase
'Usage Dim instance As FilterControl Dim value As FilterExpressionBase instance.DataSourceFilterExpression = value value = instance.DataSourceFilterExpression
public FilterExpressionBase DataSourceFilterExpression {get; set;}
The FilterControl acts as a delay-providing link between the SearchTextBox and the ListBox. It contains an ApplyFilterInterval property, which represents the amount of time the FilterControl waits after a change to UIFilterExpression (bound to the SearchTextBox's FilterExpression with two-way binding) before the filter is used to update DataSourceFilterExpression (bound to the FilterExpression property of the ListBox with two-way binding). This prevents DataSourceFilterExpression from being updated after each keypress: instead, the property is updated only after 700 milliseconds have elapsed, by default.
The DataSourceFilterExpression is in effect the "output" of the FilterControl and is updated using UIFilterExpression after ApplyFilterInterval.
