你要找的是DataList的EditItem的子控件，可以这样：
protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e)
{
if (e.CommandName == "test")
{
DataList dl=((DataList)source);
Label label =(Label)( dl.Items[dl.EditItemIndex].FindControl("Label1"));
label.Text = "adfad";
}
}
protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e)
{
if (e.CommandName == "test")
{
DataList dl=((DataList)source);
Label label =(Label)( dl.Items[dl.EditItemIndex].FindControl("Label1"));
label.Text = "adfad";
}
}
