for (int i = 0; i <= Repeater0.Items.Count - 1; i++)

string connection = "server=sv01;database=testdb;uid=sa;password=mpx123";
Repeater Repeater1 = (Repeater)Repeater0.Items[i].FindControl("Repeater1");
HiddenField QID = (HiddenField)Repeater0.Items[i].FindControl("QID");
SqlConnection ak = new SqlConnection(connection);
ak.Open();
string query = "Select * from [dbo].[t_Answers] where QId=" + QID.Value;
SqlDataAdapter adp= new SqlDataAdapter(query, ak);
DataTable ck = new DataTable();
//ck.Columns.Add("AOptions");
adp.Fill(ck);
Repeater1.DataSource = ck;
Repeater1.DataBind();
ak.Close();

{
var collection = Repeater0.Items.Count;
foreach (var item in collection)
{
}
}
}
我在这里使用了两个中继器，一个用于提问，问题ID和其他用于单选按钮获取数据从数据库，但现在我不知道如何保存每个单选按钮组成的数据，只要用户要检查该选项。
我尝试过：
我正在尝试 - 每个循环但不知道如何将它与嵌套转发器一起使用
protected void BtnSubmit_Click（object sender，EventArgs e）
{
var collection = Repeater0.Items.Count; < br $>
foreach（收藏中的var项目）
{
}
}
I have used two repeater in this, one for question,question Id and other for radio button to get data from database, but now i don't know how to save data that every radio button consist whenever user gonna check that option .
What I have tried:
I am trying for-each loop but don't know how to use it with nested repeater
protected void BtnSubmit_Click(object sender, EventArgs e)
{
var collection = Repeater0.Items.Count;
foreach (var item in collection)
{
}
}
推荐答案
最简单的方法是从请求中读取答案。单选按钮的名称是问题ID，所以如果你Request.Form [QId]你会得到选定的答案
Simplest way is to read the answers from the Request. The "name" of your radio buttons are the question ID so if you Request.Form[QId] you'll get the selected answer
protected void BtnSubmit_Click(object sender, EventArgs e)
{
var collection = Repeater0.Items;
foreach (RepeaterItem item in collection)
{
HiddenField QID = (HiddenField)item.FindControl("QID");
int q = int.Parse(QID.Value);
string answer = Request.Form[q.ToString()];
}
}
另一种方法是使用服务器端单选按钮，或者radiobuttonlist，并以编程方式访问这些控件。
An alternative would be to use server-side radio buttons, or a radiobuttonlist, and access those controls programmatically.
