Assuming this is C#/.NET, creating your own user control is an appropriate solution to this problem. Instead of inheriting from UserControl, your control should instead inherit from TextBox - this will make your control look and act just like an ordinary TextBox, and you can add code to handle the fading effect:
public partial class MyCustomTextbox : Textbox
{
}
To do the fading, you'd have to create some sort of timer to progressively change BackColor with a function like this:
function FadeBackground(float progress)
{
Color color = Color.FromArgb(255, (int)((1 - progress) * 255),
(int)((1 - progress) * 255));
base.BackColor = color;
}
When parameter progress = 0, this will produce a white background, and when progress = 1 this will be full red.

假设这是 C#/.NET，创建您自己的用户控件是解决此问题的适当方法。 您的控件不应从
UserControl继承，而应从TextBox继承 - 这将使您的控件的外观和行为就像普通的TextBox一样，并且您可以添加代码来处理淡入淡出效果：要实现淡入淡出，您必须创建某种计时器来使用如下函数逐步更改

progress = 0，这将产生白色背景，当progress= 1 时，这将产生全红色。Assuming this is C#/.NET, creating your own user control is an appropriate solution to this problem. Instead of inheriting from
