button.Enabled= false; // here the button's color becomes gray and i dont want this attitude i want to be enabled where at the begining of the application when all buttons are disabled its color is qiut simmilar to button's background. So why this color ?

Answer 1

I am not entirely sure I read your problem correctly, but It seems to me like maybe you want something like this:

button.Enabled = Condition; // Initial value


// user clicked on button
button.Enabled= false; 
 ... do button's function ...
button.Enabled = Condition

This should restore the state of the button as before the click, basically just disabling it while processing is taking place.

Answer 2

The disabled state for most winform controls is largely fixed by the Win32 control set. If you don't like it, then either:

• don't actually disable it - just change the color manually, disable tab-stops, and ignore clicks while it is "kinda-disabled"
• use WPF, which has a completely separate implementation and doesn't suffer from the Win32 roots
• write your own button control from scratch (don't touch the Win32 one)
• use a 3rd-party button control

Answer 3

禁用按钮后更改颜色

Answer 4

I had a similar issues with TextBox's before. The best way to avoid this problem is to just reset the color after disabling the Button.

var color = button.BackgroundColor;
button.Enabled = false;
button.BackgroundColor = color;
