各位大侠呀，通常页面的清空就在页面处理就可以了。不要写到后台的呀，一看有DropDownList就知道是B/S嘛

void Find(Control.ControlCollection ctls)
{
foreach (Control c in ctls)
{
if (c is TextBox)
{
Textbox tb = c as TextBox;
tb.Text="";
}
if (c is DropDownList)
{
DropDownList ddl= c as DropDownList;
ddl.SelectedVlue="";
}
if (c.Controls != null) Find(c.Controls);
}
}
{
foreach (Control c in ctls)
{
if (c is TextBox)
{
Textbox tb = c as TextBox;
tb.Text="";
}
if (c is DropDownList)
{
DropDownList ddl= c as DropDownList;
ddl.SelectedVlue="";
}
if (c.Controls != null) Find(c.Controls);
}
}
