Question

I’m using XML to create a custom Excel Ribbon in which I have a button that contains an image. I would like to be able to change this image when the button is pressed (like a toggle) to show what state it’s in. I have the following XML to describe the button:

<button id="MyButton"
            label="MyLabel"
            screentip="Some useful info."
            onAction="MyAction"
            getImage="GetImage"
            size="large"/>

Where the MyAction method is defined as:

public void MyAction(Office.IRibbonControl control)
{
     // Change button image here...
}

Is there some way I can change the button’s image in the MyAction() method?

Cheers

It looks as though you are correct. The only way I have found to edit the appearance of custom ribbon elements is to use ‘Ribbon (Visual Designer)’ and not XML.

For example, if I want to change an image on a toggle button called toggleButton1 I can do the following:

public void toggleButton1_Click(object sender, RibbonControlEventArgs e)
{
    toggleButton1.Image = GetImage(toggleButton1.Checked);
}

where GetImage is defined as:

public Bitmap GetImage(bool pressed)
{      
    return new Bitmap(pressed ? Properties.Resources.img_1 : Properties.Resources.img_2);
}
