使用Panel提示当前位置

第一步：创建一个Windows窗体应用程序项目PanelTip。


第二步：编写计算代码
private void button1_Click(object sender, EventArgse)

{

            doubleordinarySalary = Convert.ToDouble(textBox8.Text);  //工作日时薪

            doubleholidaySalary = Convert.ToDouble(textBox9.Text);   //节假日时薪

            //每天工作时间

            doublemonday = Convert.ToDouble(textBox1.Text);

            doubletuesday = Convert.ToDouble(textBox2.Text);

            doublewednesday = Convert.ToDouble(textBox3.Text);

            doublethursday = Convert.ToDouble(textBox4.Text);

            doublefriday = Convert.ToDouble(textBox5.Text);

            doublesaturday = Convert.ToDouble(textBox6.Text);

            doublesunday = Convert.ToDouble(textBox7.Text);

            //工作日为周一到周五，节点日为周六和周日

            doubleweekday = monday + tuesday + wednesday + thursday + friday;

            doubleholiday = saturday + sunday;

            //计算薪水并显示

            doubleallSalary = ordinarySalary * weekday + holidaySalary * holiday;

           textBox10.Text =allSalary.ToString();
}

   
第三步：编写各个Panel的进入和离开事件代码。
private void panel1_Enter(object sender, EventArgse)
{

        panel1.BorderStyle = BorderStyle.Fixed3D;

}

   
private voidpanel1_Leave(object sender, EventArgs e)

{

        panel1.BorderStyle = BorderStyle.FixedSingle;

}

      
private voidpanel2_Enter(object sender, EventArgs e)

{

        panel2.BorderStyle = BorderStyle.Fixed3D;

}

      
private voidpanel2_Leave(object sender, EventArgs e)

{

        panel2.BorderStyle = BorderStyle.FixedSingle;

}

      
private voidpanel3_Enter(object sender, EventArgs e)

{

        panel3.BorderStyle = BorderStyle.Fixed3D;

}

      
private voidpanel3_Leave(object sender, EventArgs e)

{

       panel3.BorderStyle = BorderStyle.FixedSingle;

}
