DataGridViewCell.OnMouseEnter(Int32) 方法

  • 参考

定义

命名空间:
System.Windows.Forms
程序集:
System.Windows.Forms.dll

当鼠标指针移到单元格上时调用。

protected:
 virtual void OnMouseEnter(int rowIndex);
protected virtual void OnMouseEnter (int rowIndex);
abstract member OnMouseEnter : int -> unit
override this.OnMouseEnter : int -> unit
Protected Overridable Sub OnMouseEnter (rowIndex As Integer)

参数

rowIndex
Int32

该单元格的父行索引。

示例

下面的代码示例演示了此方法的使用。 本示例是如何：通过扩展其行为和外观自定义 dataGridView 控件中Windows 窗体单元格和列中提供的更大示例的一部分。

// Force the cell to repaint itself when the mouse pointer enters it.
protected override void OnMouseEnter(int rowIndex)
{
    this.DataGridView.InvalidateCell(this);
}

// Force the cell to repaint itself when the mouse pointer leaves it.
protected override void OnMouseLeave(int rowIndex)
{
    this.DataGridView.InvalidateCell(this);
}

' Force the cell to repaint itself when the mouse pointer enters it.
Protected Overrides Sub OnMouseEnter(ByVal rowIndex As Integer)
    Me.DataGridView.InvalidateCell(Me)
End Sub

' Force the cell to repaint itself when the mouse pointer leaves it.
Protected Overrides Sub OnMouseLeave(ByVal rowIndex As Integer)
    Me.DataGridView.InvalidateCell(Me)
End Sub

注解

此方法类似于 DataGridView.OnCellMouseEnter 方法。 它在引发事件的相同情况下 DataGridView.CellMouseEnter 调用，但它实际上不会引发事件。
