如何在gridview中为动态添加的下拉列表设置验证器 [英] how to set validator for dynamically added dropdownlists in gridview

问题描述

我在gridview中动态添加了下拉列表。

如果用户选择5，则会出现5个下拉列表。

我需要的是用户必须选择第一个下拉列表，按订单排名第2，第3位。

如何为此设置验证器？或者有什么选择吗？

请求我。

What i need is user has to select the 1st dropdownlist, 2nd,3rd by order.
how to set validator for that? or is there any option for that?
pls sugest me.

推荐答案

以上评论中的两个建议都是有效的解决方案。我想我会添加它。



您可以使用每个下拉列表中的SelectedIndexChanged事件来显示或启用以下下拉列表。它看起来像这样：

Both of the suggestions in the comments above are valid solutions. I thought I would add this though.

You could use the SelectedIndexChanged event for each dropdownlist to make visible or enable the following dropdownlists. It would look something like this:

protected void dropdownlist_SelectedIndexChanged(object sender, EventArgs e)
    {
        dropdownlist2.Visible = true;  
        //or
        dropdownlist2.Enabled = true;

    }
