[問題] Panel 切換
我遇到的問題如下
我有一個form 3個panel，分別叫P1 P2 P3
希望做到
P1裡面有個按鈕按下去會切換到其他Panel P2或P3
P1內的按鈕叫做button1
Code的部分
public Form1()
{
InitializeComponent();
panel1.Visible = true;
panel2.Visible = false;
panel3.Visible = false;
}
private void button1_Click_1(object sender, EventArgs e)
{
panel2.Visible = true;
}
以上這樣寫OK
--------------------------------------------------------------
但是如果我改成
private void button1_Click_1(object sender, EventArgs e)
{
panel1.Visible = false;
panel2.Visible = true;
panel3.Visible = false;
}
畫面show出的是空白一片
或者
private void button1_Click_1(object sender, EventArgs e)
{
panel1.Visible = false;
panel2.Visible = false;
panel3.Visible = true;
}
空白一片
或者
private void button1_Click_1(object sender, EventArgs e)
{
panel1.Visible = false;
panel2.Visible = false;
panel3.Visible = true;
}
也是空白一片
請問該怎麼解決這樣的問題?為什會這樣?
希望高手解答
