C#

public class TableViewHitInfo :
    GridViewHitInfoBase,
    ITableViewHitInfo,
    IDataViewHitInfo

VB.NET

Public Class TableViewHitInfo
    Inherits GridViewHitInfoBase
    Implements ITableViewHitInfo,
               IDataViewHitInfo

Related API Members

The following members accept/return TableViewHitInfo objects:

• TableView.CalcHitInfo(DependencyObject)
• TableView.CalcHitInfo(Point)

Remarks

Hit testing allows you to recognize which element is located at the specified screen coordinates. For instance, you may have to determine which part of a Table View a user has clicked or double-clicked. To obtain this information, use the TableView.CalcHitInfo method. This method returns the TableViewHitInfo object whose properties can be grouped into three logical categories:

• Properties identifying the visual element of a View that contains the test object. For instance, the GridViewHitInfoBase.Column and GridViewHitInfoBase.RowHandle properties identify the column and row whose elements are under the test object;
• Properties indicating whether the test object resides over a particular View element. For instance, the GridViewHitInfoBase.InColumnPanel property indicates whether the test object is over the column header panel;

• The TableViewHitInfo.HitTest property identifies the visual element located under the test object.
