标题[请益] 请问ASP.NET Autopost的问题
时间Tue Aug 29 12:12:34 2006
我将checkboxlist、radiobuttonlist、dropdownlist、listbox使用AutopostBack属性，
变换选取项目後将文字显现在literal上，但dropdownlist跟listbox没有将文字显示在
literal上，但若将该两项用button点选便有显示在literal上，想请教大大这是什麽缘故
我是用Visual studio 2005编译的
protected void CheckBoxList1_SelectedIndexChanged(object sender, EventArgs e)
{
this.Literal1.Text = this.CheckBoxList1.Text;
}→literal有显示出来
protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e)
{
this.Literal1.Text = this.RadioButtonList1.Text;
}→literal有显示出来
protected void Button1_Click(object sender, EventArgs e)
{
this.Literal1.Text = this.DropDownList1.SelectedValue;
}→literal有显示出来
protected void Button2_Click(object sender, EventArgs e)
{
this.Literal1.Text = this.ListBox1.Text;
}→literal有显示出来
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
this.Literal1.Text = this.DropDownList1.Text;
}→literal无显示
protected void ListBox1_SelectedIndexChanged(object sender, EventArgs e)
{
this.Literal1.Text = this.ListBox1.SelectedValue;
}→literal无显示
