禁用 C# 时更改文本框颜色 [英] Change a textbox colour when disabled C#

问题描述

我要问同样的问题，就像我看到的其他话题一样.

i am going to ask the same thing like other topic which I have seen.

当我使用 Textbox.Enable 或 Textbox.readOnly 时，文本框会变成深色，我该如何更改此颜色以获得更好的颜色?(白色可能更好).

When i use the Textbox.Enable or Textbox.readOnly, the textbox gets a dark colour, how can i change this colour for a better colour? (white could be better).

推荐答案

禁用 TextBox 时，它会忽略 ForeColor.您可以通过实现自定义绘画来覆盖它.

When a TextBox is disabled, it ignores the ForeColor. You can override this by implementing your custom painting.

来自线程:-

您可以像这样覆盖 OnPaint 事件:-

You can override the OnPaint event like something like this:-

protected override void OnPaint(PaintEventArgs e)
{
     SolidBrush drawBrush = new SolidBrush(ForeColor);
     // Draw string to screen.
     e.Graphics.DrawString(Text, Font, drawBrush, 0f,0f); 
}
set the ControlStyles to "UserPaint"

public MyTextBox()//constructor
{
     // This call is required by the Windows.Forms Form Designer.
     this.SetStyle(ControlStyles.UserPaint,true);

     InitializeComponent();

     // TODO: Add any initialization after the InitForm call
}
