                                </Setter.Value>
                            </Setter>
                            <Setter Property="BorderBrush" TargetName="border" Value="#FFDDDDDD">

                                <Setter.Value>
                                    <ImageBrush ImageSource="Cancel (Pressed).bmp"/>
                                </Setter.Value>
                            </Setter>
                            <Setter Property="BorderBrush" TargetName="border" Value="#FF2C628B"/>
                        </Trigger>
                        <Trigger Property="ToggleButton.IsChecked" Value="True">
                            <Setter Property="Background" TargetName="border" Value="#FFBCDDEE"/>
                            <Setter Property="BorderBrush" TargetName="border" Value="#FF245A83"/>
                        </Trigger>
                        <Trigger Property="IsEnabled" Value="False">
                            <Setter Property="Background" TargetName="border" Value="#FFF4F4F4"/>
                            <Setter Property="BorderBrush" TargetName="border" Value="#FFADB2B5"/>
                            <Setter Property="TextElement.Foreground" TargetName="contentPresenter" Value="#FF838383"/>
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</Window.Resources>
<Button Content="" HorizontalAlignment="Left" Margin="174,226,0,0" VerticalAlignment="Top" Width="161" Height="24" Style="{DynamicResource ButtonStyle1}"/>

And such c# code

  using System.Windows;

namespace Imagebind
{
    public partial class MainWindow : Window
    {
        private string language;
        public MainWindow()
        {
    string language = "english";
            InitializeComponent();
            if (language == "english")
            {
            /* Here I need to change Imagesource of ImageBrush of 3 state buttons programmaticaly
For example this Cancel (Mouseover).bmp for Cancel(english) (Mouseover).bmp
*/
            }
        }
    }
}

So all I wanted is that if user has different languages all images in interface will be in language that I setted up conditions. So I need to change all images of buttons in all states to new in c# code.

If you are trying to localize your application, you should consider looking into existing libraries to help you out, such as WPFLocalizationExtension.

To answer your immediate question, you could define all of your images as either static properties or as resources somewhere in your application, and assign them to the correct values based on the language. If you don't need to support changing the language while the application is running, static properties will be easier to setup.

Simply define properties like this:

internal static class Images
{
    public static Uri CancelMouseOver { get; set; }
}

Set them like this:

Images.CancelMouseOver = new Uri("Cancel(english) (Mouseover).bmp", UriKind.Relative);

Then use them like this:

<ImageBrush ImageSource="{x:Static local:Images.CancelMouseOver}"/>
