C＃：背景颜色问题

Question

I am having trouble with background colors in C#. For some reason they are simply not working. Specifically on the System.Windows.Forms.Panel control. Setting the BackColor property does nothing. All I have is gray and all the efforts I have made will not change it. Is there something that could be overriding this? Am I approaching this the wrong way?

Answer 1

I had this problem with two overlayed panels in one form. I inadvertently had one panel as a child of the other main when I created them in Design View.

Answer 2

If you want to have the Panel Control the same color as the Form's background color, then you can use this:

myPanel.Parent = this;

... I hope this helps :)

Answer 3

我有一些实例，其中控件必须同时指定了前景色和背景色，您可能还想尝试显式设置前景色，以查看是否可行。

Answer 4

It may be that your control is being repainted without your knowledge.

To try to rule this out, I would add a Form Load event, and force the following properties:

private void Form1_Load(object sender, EventArgs e)
{
   this.panel1.BackColor = System.Drawing.Color.Maroon; // or any other color
   this.panel1.Visible = true
}

And on the designer, I would bring the control to the foreground.
