Question

I need to change the background colour of a button using C# code (Visual Studio 2008).

I saw some people recommending the inclusion of a directive: using System.Windows.Media; – I tried it and it triggered this error: Windows does not exist in namespace System. I tried several combinations like:

 btn.BackColor = Color.Red;
 btn.Background = Brushes.Green;

And neither is working. Is a special directive needed for using colour? What code do you suggest. Thanks a lot.

Answer 1

This should change your button background color to Red

yourButtonName.BackColor = Color.Red;

You need to include System.Drawing namespace as Color class belongs to that. Like this

using System.Drawing;

And ofcourse you need to add the reference to System.Drawing DLL in your project to use this namespace and Color class.
