求简单代码
protected void btn1_Click(object sender, EventArgs e)
{
btn1.ForeColor = System.Drawing.Color.FromName( "blue ");
btn2.ForeColor = System.Drawing.Color.FromName( "white ");
btn3.ForeColor = System.Drawing.Color.FromName( "white ");
btn4.ForeColor = System.Drawing.Color.FromName( "white ");
btn5.ForeColor = System.Drawing.Color.FromName( "white ");
}
怎样实现批处理?其他LinkButton有同样的功能
------解决方案--------------------你想要怎样的批处理?
------解决方案--------------------如果是完成同样的功能,用同一个事件委托,或是写成一个方法,分别调用
------解决方案--------------------for(int i=1;i <10;i++)
{
(Button)this.FindControl( "btn1 ").ForeColor = System.Drawing.Color.FromName( "blue ");
}
------解决方案--------------------如果是改变所有按钮的属性的话,委托可以
------解决方案--------------------如果完成同样的功能,用同一个事件处理程序即可
------解决方案--------------------这样好像没有办法批处理把
------解决方案--------------------public Form1()
{
InitializeComponent();
foreach (Button btn in Controls)
{
if (btn != null)
{
btn.Click+=new EventHandler(ButtonClick);
}
}
}
private void ButtonClick(object sender, EventArgs e)
{
foreach (Button btn in Controls)
{
if(btn!=null)
{
btn.ForeColor = System.Drawing.Color.FromName( "white ");
}
}
(sender as Button).ForeColor = System.Drawing.Color.FromName( "blue ");
}
------解决方案--------------------for(int i=1;i <10;i++)
{
(Button)this.FindControl( "btn1 ").ForeColor = System.Drawing.Color.FromName( "blue ");
}
---------------------------------
人家是点击事件
------解决方案--------------------我的是WinForm 忘了说了
------解决方案--------------------protected void btn_Click(object sender, EventArgs e)
{
(sender as LinkButton).ForeColor = System.Drawing.Color.FromName( "blue ");
foreach(Control c in this.Controls)
{
if(c is LinkButton)
(c as LinkButton).ForeColor = System.Drawing.Color.FromName( "white ");
}
}
然后所有的 LinkButton.Click += new EventHandler(btn_Click);
