使用例

[Visual Basic, C#, C++] System.Windows.Forms.DataGrid コントロールの MouseDown イベント内から HitTest メソッドを呼び出すことにより、グリッド内でクリックされた部分に関する情報を出力する例を次に示します。この例では、 DataGrid.HitTestInfo オブジェクトが返されます。

    ' 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.
