如何在按钮单击并将鼠标悬停在事件后更改按钮背景颜色。 [英] How to change button backcolor after button click and mouse over event.

问题描述

我想做的是

1）每当我将鼠标移到按钮上时，它的颜色应为蓝色。

2）当我的鼠标离开按钮时，它的颜色应该变为正常。

3）每当我将鼠标移到按钮上时，它的颜色应为蓝色

4）然后当我点击该按钮时，它的颜色应该改为红色。

5）按钮点击后我的鼠标离开按钮的颜色应该红色本身。

6）下次当我将鼠标移到按钮上时，它的颜色应该变为蓝色。

7）然后，当我的鼠标离开按钮时，它的颜色应该是红色本身



这里我得到了所有6个步骤，现在我需要迈出第7步......我该怎么做。



提前谢谢。



我尝试过的事情：


$ 1,2 $ 5 1,2,3,5步骤b
private void btnDateTime_MouseHover（object sender，EventArgs e）
{
if（btnDateTime.BackColor！= Color.Empty&& btnDateTime.BackColor！= Color.Red）
{
btnDateTime.BackColor = Color.Blue;
}

if（btnDateTime.BackColor == Color.Red）
{
btnDateTime.BackColor = Color.Blue;
}
}

第四步

 private void btnDateTime_Click（object sender，EventArgs e）
 {
 btnHi.Visible = true; 
 if（btnDateTime.BackColor == Color.Blue）
 {
 btnDateTime.BackColor = Color.Red; 
} 
 else 
 {
 btnDateTime.BackColor = default（Color）; 
} 
} 
 

第7步我该怎么办？

解决方案

试试

 bool isclicked = false; 
 private void button1_Click（object sender，EventArgs e）
 {
（发送者为Button）.BackColor = System.Drawing.Color.Red; 
 isclicked = true; 
} 
 
 private void button1_MouseHover（object sender，EventArgs e）
 {
（发送者为Button）.BackColor = System.Drawing.Color.Blue; 
} 
 
 private void button1_MouseLeave（object sender，EventArgs e）
 {
 System.Drawing.Color defaultColor = System.Drawing.SystemColors.Control; 
（发件人为Button）.BackColor = isclicked？ System.Drawing.Color.Red：defaultColor 
 
} 
 

what i am trying to do is
1)Whenever i move my mouse over button it's color should be Blue.
2)when my mouse leaves the button it's color should become normal.
3)Whenever i move my mouse over button it's color should be Blue
4)Then when i click that button its color should be changed to Red.
5)after button click when my mouse leaves the button its color should be red itself.
6)next time when i move my mouse over the button it's color should become blue.
7)Then when my mouse leaves the button its color should be red itself

Here i got all the 6 steps and now i need to get the 7th step.. how do i do it.

Thank you in advance.

What I have tried:

for 1,2,3,5 and 6 steps

 private void btnDateTime_MouseHover(object sender, EventArgs e)
{
if (btnDateTime.BackColor != Color.Empty && btnDateTime.BackColor != Color.Red)
            {
                btnDateTime.BackColor = Color.Blue;
            }
            
            if (btnDateTime.BackColor == Color.Red)
            {
                btnDateTime.BackColor = Color.Blue;
            }
}

for 4th step

private void btnDateTime_Click(object sender, EventArgs e)
       {
           btnHi.Visible = true;
           if(btnDateTime.BackColor == Color.Blue)
           {
               btnDateTime.BackColor = Color.Red;
           }
           else
           {
               btnDateTime.BackColor = default(Color);
           }
       }

for 7th step what should i do??

解决方案

try

bool isclicked = false;
       private void button1_Click(object sender, EventArgs e)
       {
           (sender as Button).BackColor = System.Drawing.Color.Red;
           isclicked = true;
       }

       private void button1_MouseHover(object sender, EventArgs e)
       {
           (sender as Button).BackColor = System.Drawing.Color.Blue;
       }

       private void button1_MouseLeave(object sender, EventArgs e)
       {
           System.Drawing.Color defaultColor = System.Drawing.SystemColors.Control;
           (sender as Button).BackColor = isclicked ? System.Drawing.Color.Red: defaultColor

       }
