获取中继器内从单选按钮选定的单选按钮列表值 [英] Get selected radio button list value from radio buttons inside a Repeater

问题描述

我有一个中继器内的单选按钮列表。我显示的是什么，这看起来像一个屏幕截图。我有中继器的头部模板中的列标题。在项目模板，我有4个字段/列。第3场是一个单选按钮列表。如果，例如，我选择测试任务2行中的是单选按钮 - 我需要回发并保存记录（回数据库）的值。我的中继器可能显示字段和单选按钮列表的多行。

I have a radiobuttonlist inside a repeater. I am showing a screenshot of what this looks like. I have column headers inside the header template of the repeater. In the item template, I have the 4 fields/columns. The 3rd field is a radio button list. If, for example, I select the "Yes" radio button in the "Test Task 2" row - I need to postback and save the value of that record (back to a database). My repeater could potentially display many rows of fields and radio button lists.

推荐答案

试试这个

protected void btnSave_Click(object sender, EventArgs e)
    {
        foreach (RepeaterItem item in Repeater1.Items)
        {
            // Checking the item is a data item
            if (item.ItemType == ListItemType.Item || item.ItemType == ListItemType.AlternatingItem)
            {
                var rdbList = item.FindControl("RadioButtonList1") as RadioButtonList;
                // Get the selected value
                string selected = rdbList.SelectedValue;
            }
        }
    }
