Set Foreground Color and Using System Resources

Question

Hi, 

I am attempting to set the foreground color on a button using C#, but I have not been able to find a way to do this (even the MS document does not work). Here is the code I am attempting to use: 

ItemHDSCustodySignBtn.Foreground = Brushes.Blue;

This code is invalid. Additionally, I would prefer to use the exact numeric value rather than the string name of the color. 

My second problem is how I can apply a style to my button. I have a style that is accessible throughout the app, however, I cannot find documentation anywhere in how to do this in C# rather than XAML. 

Thanks for your help with this.

Hi JB,

Problem one:

ItemHDSCustodySignBtn.Foreground = new SolidColorBrush(Colors.Blue);

When you want to use the exact numeric value, you could either use the static Color.FromArgb-Method to create the color object or you can set the A R G B-Properties manually and for example parse a hex-string like it is done here:

Problem two:

WinRT doesn't contain a FindResource-Method. But you could still grab resources and so your still:

Thanks for your reply. You solved my issues perfectly. 

On another note, do you know how I can retrieve a value (such as a margin) set in the XAML? I want to adjust it programmatically in the back .cs file. (Ex. get the height and change it)

And lastly, does Windows have a nonabbreviated version of margins? Instead of combining, let's say I just want to adjust the top margin. Is there any kind of margin-top tag I can use instead? 

Thanks so much for your help.

Hi,

 Margin  properties are set using a new Thickness created with the uniform-value constructor:

 DeptStackPanel.Margin = new Thickness(10);

Please refer to the link below:

In XAML there is no margin-top property, but in Html development,you can use it:

Best Wishes!
