Foreground color of an image is changing to white when I click/press the ImageButton

[rajeev]

Hi,

I am assigning an image to imagebutton as RestStateImageSoure and setting Foreground color to Black. When I launch the App, it showing image in back color correctly. But when I press/hold the button, Image color is changing to white. How to change this behavior.

Thanks in advance

Hi,

In this case you can redefine the PressedStateWithOpacityMaskForegroundFillBrush named brush that controls this behavior.

Let me know if this helps.

Hi Ivaylo Gergov,

Thanks for your reply.

Could you explain how to define this. I have tried but couldn't find anything like "PressedStateWithOpacityMaskForegroundFillBrush ".

My code in .xaml:

<tp:RadImageButton  Background="{StaticResource PhoneColor}" x:Name="imgMobile" ButtonShape="Ellipse" ButtonType="Custom" RestStateImageSource="/Assets/Icons/Mobile_D.png" Foreground="Black"   Width="150" Height="150" />

in MainPage.cs:

         if (DeviceNetworkInformation.IsCellularDataEnabled)
            {
                imgMobile.RestStateImageSource = new BitmapImage(new Uri("/Assets/Icons/Mobile_E.png", UriKind.Relative));
                imgMobile.Foreground = new SolidColorBrush(Colors.White);
            }
            else
            {
                imgMobile.RestStateImageSource = new BitmapImage(new Uri("/Assets/Icons/Mobile_D.png", UriKind.Relative));
                imgMobile.DisabledStateImageSource = new BitmapImage(new Uri("/Assets/Icons/Mobile_D.png", UriKind.Relative));
                imgMobile.Foreground = new SolidColorBrush(Colors.Black);
            }
Where I need to implement your changes?

Hi,

You need to extract the template of the control by right-clicking it in Visual Studio's designer and choosing Edit Template -> Edit a Copy. This will extract the default style and you will be able to locate the PressedStateWithOpacityMaskForegroundFillBrush and change its value.

I hope this information helps.
