**程序集:**System.Windows.Forms（在 system.windows.forms.dll 中）

语法

声明
Public ReadOnly Property Type As HitTestType
用法
Dim instance As HitTestInfo
Dim value As HitTestType

value = instance.Type

public HitTestType Type { get; }

public:
property HitTestType Type {
    HitTestType get ();
}

/** @property */

public function get Type () : HitTestType

属性值

DataGrid.HitTestType 枚举之一。

示例

下面的示例通过从 System.Windows.Forms.DataGrid 控件的 MouseDown 事件内部调用 HitTest 方法了，来打印网格中被单击的部分。这将返回一个 DataGrid.HitTestInfo 对象。

Private Sub dataGrid1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs)
    Dim newLine As String = ControlChars.Cr
    Console.WriteLine(newLine)
    Dim myHitTest As System.Windows.Forms.DataGrid.HitTestInfo
    ' Use the DataGrid control's HitTest method with the x and y properties.
    myHitTest = dataGrid1.HitTest(e.X, e.Y)
    Console.WriteLine(("Hit " & ReturnHitTest(myHitTest.Type)))
End Sub 'dataGrid1_MouseDown


Private Function ReturnHitTest(hit As System.Windows.Forms.DataGrid.HitTestType) As String
    ' Use this function to return the part of the grid clicked.   
    Select Case hit
        Case System.Windows.Forms.DataGrid.HitTestType.Cell
                Return "Cell"
        
        Case System.Windows.Forms.DataGrid.HitTestType.Caption
                Return "Caption"
        
        Case System.Windows.Forms.DataGrid.HitTestType.ColumnHeader
                Return "ColumnHeader"
        
        Case System.Windows.Forms.DataGrid.HitTestType.ColumnResize
                Return "Resize"
        
        Case System.Windows.Forms.DataGrid.HitTestType.ParentRows

                Return "RowResize"
        
        Case System.Windows.Forms.DataGrid.HitTestType.None
                Return "None"
        
        Case Else
