Chnage Telerik WPF按钮颜色通过代码

Question

I learning WPF and build an simple application. This is my button:

<Button x:Name="btnAddFiles" Content="Add" HorizontalAlignment="Left" Margin="1046,34,0,0" VerticalAlignment="Top" 
        Width="111" Height="34" FontSize="20" Foreground="{DynamicResource {x:Static SystemColors.ActiveBorderBrushKey}}" 
        Background="{x:Null}" MouseEnter="btnAddFiles_MouseEnter" BorderBrush="Transparent" />

And this is how it looks like:

I have changed the button background color to Transparent so the background color the you see is all my application background color. All i want to do is when the mouse is over the button change the background color to Transparent . Currently this is the current when mouse is over:

So i registered to MouseEnter event :

private void btnAddFiles_MouseEnter(object sender, MouseEventArgs e)
{
    //btnAddFiles.Background = // change the color
}

But i can see that btnAddFiles.Background require Brush and nor Color Any idea hot to change it ?

Answer 1

i couldn't see your pictures but this is how we change back color in wpf:

btnAddFiles.Background = Brushes.Transparent;

and you can use your code in a mouse enter and mouse leave event.

1st Edit

private void btnAddFiles_MouseEnter(object sender, MouseEventArgs e)
{
    btnAddFiles.Background = Brushes.Transparent;
}

private void btnAddFiles_MouseLeave(object sender, MouseEventArgs e)
{
    btnAddFiles.Background = Brushes.Lime;
}

2nd Edit:

for changing border color and thickness:

button1.BorderBrush = Brushes.Red;
Thickness t = new Thickness(5, 5, 5, 5);
button1.BorderThickness = t;

also change your margin, it is out form. try for example

Margin="50,50,0,0"

let me know if you get your answer.
