changing panel colors
提问by tintincutes
I created a simple code here just to play C# around. It has 3 buttons and 1 panel. If you click on the 2nd & 3rd button the panel height changes. Is that also possible to change the color? For example : If I click on the 2nd button, I would like to have it as yellow and at the same time the height changes as well. and the same with 3rd button. Thanks :-)
我在这里创建了一个简单的代码来玩 C#。它有 3 个按钮和 1 个面板。如果您单击第二个和第三个按钮，面板高度会发生变化。这也可以改变颜色吗？例如：如果我点击第二个按钮，我想让它变成黄色，同时高度也会改变。与第三个按钮相同。谢谢 ：-）
public partial class Form1 : Form
{
public int heightPanel;
public Form1()
{
InitializeComponent();
heightPanel = panel1.Height;
}
private void button1_Click(object sender, EventArgs e)
{
panel1.Height = heightPanel;
}
private void button2_Click(object sender, EventArgs e)
{
panel1.Height = this.Height/2;
}
private void button3_Click(object sender, EventArgs e)
{
panel1.Height = this.Height - 150;
}
}
I have an idea but I don't know where to put this I think it would be something like this: panel1.Height=this.BackColor.ToString(); Any inputs?
我有一个想法，但我不知道把它放在哪里我认为它会是这样的： panel1.Height=this.BackColor.ToString(); 任何输入？
Thanks
谢谢
Hi Thanks for the reply. Yes I would like to retain the 3 colors if I click in any of the button. I'm not sure if it's possible. for ex: my button1 =pink button2=yellow button3=green If I click on the button 1 I'll see the pink color and if I click on the button2 I'll see the pink and yellow.
您好，感谢您的答复。是的，如果我单击任何按钮，我想保留 3 种颜色。我不确定这是否可能。例如：我的 button1 =pink button2=yellow button3=green 如果我点击 button 1 我会看到粉红色，如果我点击 button2 我会看到粉红色和黄色。
Is that possible?
那可能吗？
Thanks again
再次感谢

All you'd need to do would be to set the BackColoron a new line. For instance...
您需要做的就是将 设置BackColor在新行上。例如...
private void button2_Click(object sender, EventArgs e)
{
panel1.Height = this.Height/2;
panel1.BackColor = Color.Yellow;
}
private void button3_Click(object sender, EventArgs e)
{
panel1.Height = this.Height - 150;
panel1.BackColor = Color.Yellow;
}

Simple as:
简单如：
panel1.BackColor = Color.Red;
回答by Erich Mirabal
In button2_Click, just add another line like this:
在 中button2_Click，只需添加另一行，如下所示：
panel1.BackColor = Color.Yellow;
