按钮背景问题(与先前询问的问题有关) [英] Button Background problem (related to previously asked question)

问题描述

此问题与先前未解决的问题有关，将背景分配给按钮控件时出现的问题 [

This question is related to previously asked question which wasn''t solved Problem when assigning Background to Button control[^]

Starting from a scratch windows phone silverlight application. I added three buttons, button1, button2, and button3. I wrote the following code in the button1_click event handler.

private void button1_Click(object sender, RoutedEventArgs e)
       {

           button1.Background = new SolidColorBrush(Colors.Red);
           button2.Background = new SolidColorBrush(Colors.Brown);
           button3.Background = new SolidColorBrush(Colors.Yellow);

       }

仅更改button2和button3的背景，但不更改button1的背景.可能是什么问题?请帮助

Only button2 and button3 ''s background is changed, but button1''s background is not altered. What can be the problem? Please help

推荐答案

问题已解决！

代替更改实际背景本身，使用背景参考可以解决问题.

Problem solved!!

Instead of changing the actual background itself, using the reference of the background solves the problem.

private void HighlightButton(Button btnToHighlight)
        {

            SolidColorBrush sBrush = (SolidColorBrush)btnToHighlight.Background;


            sBrush.Color = //enter your colour here
            btnToHighlight.Background = sBrush;

        }

为所有按钮实现了这一点.瞧！

Implemented this for all the buttons. Voila!!!
