資料行的編號。
範例
下列範例會從 控制項的 事件 System.Windows.Forms.DataGrid 內 MouseDown 呼叫 HitTest 方法，以列印已按下的資料列和資料行編號。 這會傳回 DataGrid.HitTestInfo 物件。
private:
void dataGrid1_MouseDown( Object^ /*sender*/,
System::Windows::Forms::MouseEventArgs^ e )
{
String^ newLine = "\n";
Console::WriteLine( newLine );
System::Windows::Forms::DataGrid::HitTestInfo^ myHitTest;
/* Use the DataGrid control's HitTest method with
the x and y properties. */
myHitTest = dataGrid1->HitTest( e->X, e->Y );
Console::WriteLine( "Column {0}", myHitTest->Column );
Console::WriteLine( "Row {0}", myHitTest->Row );
}
private void dataGrid1_MouseDown
(object sender, System.Windows.Forms.MouseEventArgs e)
{
string newLine = "\n";
Console.WriteLine(newLine);
System.Windows.Forms.DataGrid.HitTestInfo myHitTest;
/* Use the DataGrid control's HitTest method with
the x and y properties. */
myHitTest = dataGrid1.HitTest(e.X,e.Y);
Console.WriteLine("Column " + myHitTest.Column);
Console.WriteLine("Row " + myHitTest.Row);
}
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(("Column " & myHitTest.Column))
Console.WriteLine(("Row " & myHitTest.Row))
End Sub
備註
如果座標不是儲存格，屬性會傳回 -1。
