Remarks

The HitTest property allows you to identify the type of a visual element located under the test object.

Some visual elements can contain other visual elements. For example, the Filter Panel displays the filter expression, filter and close buttons. In this instance, to identify whether the test object is located within the filter panel, use the GridViewHitInfoBase.InFilterPanel property, because the HitTest property can return TableViewHitTest.FilterPanel, TableViewHitTest.FilterPanelCloseButton, TableViewHitTest.FilterPanelActiveButton or TableViewHitTest.FilterPanelText.
