Change color of control to default

i do have a textbox. When there is error i set borderbrush to new SolidColorBrush(Colors.Red). When error is fixed, i want to switch to default color of border of a textbox. I am doing it in codebehind not xaml.

However it is system dependent. I noticed there is something like

SystemColor.ActiveControl etc. Should i use these and if yes, which one is default border of textbox?

Also i noticed there is something like Textbox.borderbrushproperty.defaultmetadata.defaultvalue, which i did not manage to work.

Any ideas how to switch to default borderbrush? thank you.

Maybe I'm a little late to the party but I think you're asking how to change a color to the system default of control?

someControl.BackColor = SystemColors.Control;

or 

sslEditMode.BackColor = SystemColors.ButtonFace;

Do you have to do it in code-behind? If not, you could use a Trigger which will only change the border color while the trigger condition is met.

<Style x:Key="MyTextBoxStyle" TargetType="{x:Type TextBox}">
    <Style.Triggers>
        <DataTrigger Binding="{Binding ElementName=MyUserControl, Path=HasErrors}">
            <Setter Property="BorderBrush" Value="Red" />
        </DataTrigger>
    </Style.Triggers>
</Style>

Try:

control.BackColor = Color.FromKnownColor(KnownColor.Window);

For more information, see Color.FromKnownColor on MSDN.

Why not just save the initial value at startup and use that? You should be able to use the system colors, but if you ever change the default color this will continue to work.

private Color _defBtnColor;
public MyUserControl()
{
    _defBtnColor = someButton.Foreground;
}  

private void SetBackToDefault()
{
    someButton.Foreground = _defBtnColor;
}
