protected void Page_Load(object sender, EventArgs e)
{
int nPageControls = Controls.Count;
for (int i = 0; i < nPageControls; i++) //父控件层
{
foreach (Control ctl in Page.Controls[i].Controls) //子控件层
{
if (ctl is TextBox)
{
TextBox tb = (TextBox)this.FindControl(ctl.ID);
tb.Attributes.Add("onfocus", "this.className='SpecialTxt'"); //为控件添加JavaScript事件处理
tb.Attributes.Add("onblur", "this.className='NormalTxt'");
}
}
}
}
