输入框不能保值的问题

baiyukey 2010-03-09 05:51:43

高手们帮我看看，下面的代码，当我在颜色的输入框输入文字后，再选择生成处理器输入框的下拉菜单后，颜色框里的内容就没了，我也知道在客户端不能保值的问题，因为是初学者，不知道怎么能够在生成其它输入框后，让原来的输入框里的内容保值，请高手赐教，不胜感激！

	string duima="A";

	int yanse_num=Convert.ToInt32(yanse_drop.SelectedItem.Value);

	StringBuilder yanse_str=new StringBuilder();

	for (int i=1;i<=yanse_num;i++){
