有一Table,动态生成,若干行和列。
Table里面有Label,TextBox,RadioButtonList等控件。
要取出所有RadioButtonList的值,如何做?自已写的:
foreach(Control c in Table1.Controls)
{
Response.Write(c.ToString()+"<br>");
if(c.ToString()=="System.Web.UI.WebControls.RadioButtonList")
{
RadioButtonList r=new RadioButtonList();
r=(RadioButtonList)c;
if(r.SelectedIndex!=-1)
{
Response.Write("Text="+r.SelectedItem.Text+"<br>");
Response.Write("value="+r.SelectedItem.Value+"<br>");
}
}
}通过Response.Write(c.ToString()+"<br>");测试输出
发现取出来的值是System.Web.UI.WebControls.TableRow,并不是RadioButtonList,请问?
