Image
Color
事件
ColorChanged
Clicked
已知问题
private void button1_Click(object sender, EventArgs e)
{
1 设置colorPicker1颜色的属性的时候 没有触发ColorChanged
2 设置colorPicker1颜色的属性的时候 希望自动选中已存在的名子
3 PictureBox 要背景能透明的
colorPicker1.Color = Color.Red;
}
private void colorPicker1_ColorChanged(object sender, EventArgs e)
{
label1.BackColor = colorPicker1.Color;
}
private void colorPicker1_Clicked(object sender, EventArgs e)
{
label1.BackColor = colorPicker1.Color;
