功能区按钮图像编程

Question

I'm trying to load a image onto a Ribbon Button. This is the System.Windows.Controls.RibbonBar type.

here is the code I'm using

public RibbonGroup CreateButtons()
{
    RibbonGroup GroupControlComputers = new RibbonGroup();
    GroupControlComputers.Header = "Computer Control";

    GroupControlComputers.Items.Add(DropdownButton("DropDown Stuffs"));
    return GroupControlComputers;     
}

public RibbonButton DropdownButton(String Caption)
{
    RibbonButton NewRibbonButton = new RibbonButton();
    NewRibbonButton.Label = Caption;


    NewRibbonButton.AllowDrop = true;

    return NewRibbonButton;
}

I cant figure out how to add a icon. i can add the button without an image with no problems

Path to class file creating button is MyProject\\Functions\\Ribbonbar.cs
Path to the Icon File is MyProject\\Images\\Test\\smallicon.ico

I have tried to figure out the LargeImageSource and just cant understand what I need to do.

Answer 1

There are two images which you need to specify: LargeImageSource and SmallImageSource , they actually need to be different (one - larger and one - smaller), but for test try this:

public RibbonButton DropdownButton(String Caption)
{
    RibbonButton NewRibbonButton = new RibbonButton();
    NewRibbonButton.Label = Caption;

    BitmapImage image = new BitmapImage();
    image.BeginInit();
    // your path to image might be different
    image.UriSource = new Uri("pack://application:,,,/Images/Test/smallicon.ico"); 
    image.EndInit();

    NewRibbonButton.SmallImageSource = image;
    NewRibbonButton.LargeImageSource = image;

    NewRibbonButton.AllowDrop = true;

    return NewRibbonButton;
}
