Image in WPF Button not Visible at Runtime

Change the build action to 'Resource'.Also your pack url is wrong. Either use:

Source="pack://application:,,,/Resource/UserCost2013Open16.png"

or simply

Source="/Resource/UserCost2013Open16.png"

There are 2 Solutions:

1: Change the settings of the image:

Build Action = ContentCopy to output directory = Copy if newerSource="pack://siteoforigin:,,,/Resources/UserCost2013Open16.png"

2: When Using application instead of siteoforigin in the source path, you have to possible ways:

a) Image will be in a SubFolder called "Resources" and .exe file will be small

Source="pack://application:,,,/Resources/UserCost2013Open16.png"Build Action = ContentCopy to output directory = Copy if newer

b) Image will be included in the .exe and no Subfolder with imagefile will exist

Source="pack://application:,,,/Resources/UserCost2013Open16.png"Build Action = ResourceCopy to output directory = Copy if newer

Assumeing that you have

• set your Build Action to Resource

• set that path correctly using URI-PACK-FORMAT

In my case it was still not showing.

Clean & Rebuild NOT just Build fixed it for me !
