从代码c#编辑样式WPF

Question

我遇到这样的情况:

我有一个框架在一个窗口。我有一个页面，将加载在一个框架从代码。我有一个网格的页面，有行和列的定义从代码。

我想用按钮填充网格行和列(从矩形创建)。我写了下面的代码:

应用于每个按钮的样式:

<Style TargetType="{x:Type Button}">
<Setter Property="Template">
    <Setter.Value>
        <ControlTemplate TargetType="{x:Type Button}">
            <Grid>
                <Rectangle x:Name="rect" Style="{DynamicResource rectangle_style}" Cursor="Hand">
                    <Rectangle.Fill>
                        <ImageBrush ImageSource="Attemptsimage.jpg" Stretch="UniformToFill"/>
                    </Rectangle.Fill>
                </Rectangle>
                <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Content=""/>
            </Grid>
            <ControlTemplate.Triggers>
                <Trigger Property="IsFocused" Value="True"/>
                <Trigger Property="IsDefaulted" Value="True"/>
                <Trigger Property="IsMouseOver" Value="True"/>
                <Trigger Property="IsPressed" Value="True"/>
                <Trigger Property="IsEnabled" Value="False"/>
            </ControlTemplate.Triggers>
        </ControlTemplate>
    </Setter.Value>
</Setter>

POPOLATE CLASS CODE:

 public void popolate(Grid grd)
    {
        for(int j = 1; j < 4; ++j)
        {

            for (int i = 1; i < 6;  ++i)
            {
                Button btn = new Button();
                btn.Margin= new Thickness(4,4,4,4);
                grd.Children.Add(btn);
                btn.SetValue(Grid.RowProperty, j);
                btn.SetValue(Grid.ColumnProperty, i);

            }

        }

从MAIN调用CLASS:

公共局部类MainWindow: Window{

    Page1 page = new Page1();
    Costruct costruttore = new Costruct();

    public MainWindow()
    {
        this.InitializeComponent();
                    costruttore.popolate(page.LayoutRoot);
                    frame_first.NavigationService.Navigate(page);
        // Insert code required on object creation below this point.
    }
}

我想可以设置一个不同的图像()在一个矩形的每个按钮从后面的代码。我该如何为这种必要性编写代码??

请好好解释我，因为我是WPF的校长!

Style是单个实例，如果您更改Style Image，它将更改使用Style的所有地方。

我能想到的不创建自定义控件的最简单的解决方案是使用Buttons Tag属性来传递图像文件名，Tag是DependancyProperty，所以它支持DataBinding。

的例子:

 <Style TargetType="{x:Type Button}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Button}">
                <Grid>
                    <Rectangle x:Name="rect" DataContext="{TemplateBinding Tag}" Style="{DynamicResource rectangle_style}" Cursor="Hand">
                        <Rectangle.Fill>
                            <ImageBrush ImageSource="{Binding}" Stretch="UniformToFill"/>
                        </Rectangle.Fill>
                    </Rectangle>
                    <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Content=""/>
                </Grid>
                <ControlTemplate.Triggers>
                    <Trigger Property="IsFocused" Value="True"/>
                    <Trigger Property="IsDefaulted" Value="True"/>
                    <Trigger Property="IsMouseOver" Value="True"/>
                    <Trigger Property="IsPressed" Value="True"/>
                    <Trigger Property="IsEnabled" Value="False"/>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

代码:

for (int i = 1; i < 6;  ++i)
{
    Button btn = new Button();
    btn.Margin= new Thickness(4,4,4,4);
    grd.Children.Add(btn);
    btn.SetValue(Grid.RowProperty, j);
    btn.SetValue(Grid.ColumnProperty, i);
    btn.Tag = "The filename for this buttons image";
}
