Hi all,
I am trying to set the Textbox control's color in runtime like;

TextBox1.Foreground = Brush.White;

I get an Error: 'System.Windows.Media.Brush' Does not contain a difinition for 'White'

The Code is:

C#

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Microsoft.Phone.Controls;
using System.Windows.Threading;

namespace Test1
{
    public partial class MainPage : PhoneApplicationPage
    {
	private DispatcherTimer _timer;
        

        public MainPage()
        {
            InitializeComponent();
        }

        public void RefreshUI(object sender, EventArgs e)
        {
            DateTime dt = DateTime.Now;
            if (dt.Day == 1)
            {
                TextBox1.Foreground = Brush.White;
            }
        }
    }
}

Thanks in advance.

Use Brushes.White instead.

Thank you, I was in this MSDN page, but still I don't know how to set the Brush.
Can you help me with an example?

Can you read, anyway? Kenneth told you exactly: Change "Brush" into "Brushes". If you failed to see it in the two-line answer, I can imagine how successful could be your reading of MSDN. I don't believe you have such a big cognitive problem; perhaps, just slow down.

Thanks Sergey :)

OP has a remark to you, see below :)

Dave Crump 21-Aug-12 14:30pm

@Sergey: First of all, keep your manner. Here is a development's forum not a standup comedy. Second: You can beleive in what you like, but you are not in the position to judge upon anybody.
Back to work: I tried already Brushes instead of Brush, I get the same Error. Does not matter if I code TextBox1.Foreground = Brushes.White; or TextBox1.Foreground = Brush.White;
DO I have the right using in my header.

I have verified that it works with Brushes.White, before I posted it. I dont think it work with Brush becouse it holds several different types of Brushes; Sollid/Linear/Gradient Brush, while Brushes is a SolidColorBrush. :)

Sure I will do that so long it works really. In fact still I have the same problem. Error-ID is; (Compiler Error CS0103 "The name 'Brushes' does not exist in the current context") So, as you might see, I have the "System.Windows.Media" in my header. Do I have to define it again?
Did you know that I am trying to develop on Windows Phone 7.1?

you could type in the full namespace:
System.Windows.Media.Brushes.White
and see if that works, but I dont get that error. You could also try to remove the Using block.

Dave Crump 21-Aug-12 16:05pm

Did you know, I am coding on Windows-Phone Project?
Can it be cause of the problem, that I can not use the System.Windows.Media.Brushes.White? It says "Are you missing an Assembly reference?"

Regards,

Kenneth Haugland 21-Aug-12 16:46pm

And you tell us this now? Thanks for that!
TextBox1.Foreground = new SolidColorBrush(Colors.White);

Dave Crump 21-Aug-12 16:49pm

Sorry about that!!
