'Declaration Public Property UIFilterExpression As FilterExpressionBase
'Usage Dim instance As FilterControl Dim value As FilterExpressionBase instance.UIFilterExpression = value value = instance.UIFilterExpression
public FilterExpressionBase UIFilterExpression {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 UIFilterExpression property is in effect the "input" of the FilterControl, which is used to update DataSourceFilterExpression only after ApplyFilterInterval. UIFilterExpression is updated continuously, unlike DataSourceFilterExpression.
