推荐答案

我用mouseHover事件（Visual Studio 2013 c＃）给你一个例子：

-MDIParent表格

-Form1< - 带几个按钮





[ Gif示例]



[ MDI_ChildButtonMouseHover ]



在MDI中创建DoSomeThing公共方法

I made you an example with mouseHover event (Visual studio 2013 c#):
-MDIParent Form
-Form1<- with a few buttons


[Gif Example]

[MDI_ChildButtonMouseHover]

Create the DoSomeThing public method in MDI

public void DoSomething(string controlName) {
    try
    {
        //MessageBox.Show("Mouse HOVER :" + controlName);
        toolStripStatusLabel.Text = controlName;
    }
    catch (Exception ex)
    {
        throw new Exception(ex.ToString());
    }

}

给孩子打电话：

Call the child:

private void openChildFormToolStripMenuItem_Click(object sender, EventArgs e)
{
    try
    {
        var child = new Form1();
        child.MdiParent = this; //Asign this form as parent
        child.Show();
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.ToString());
    }
}

儿童鼠标悬停事件：

Mouse Hover Event in child:

private void button1_MouseHover(object sender, EventArgs e)
{
    try
    {
        /*
         * There is a public method DoSomething in the MDIParent,
         * I send the control name to the method
         */
        ((MDIParent1)MdiParent).DoSomething("Form1 -" + ((Button)sender).Name);
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.ToString());
    }
}
