绑定单选按钮列表里面的DataList [英] Bind RadiobuttonList inside DataList
问题描述
早上好。
我在这里发帖前，搜索了很多次。
我工作的一个项目像一个调查[问答]
我能得到DataList控件中的所有问题，现在我正在寻找一种方式来显示每一个问题里面单选按钮列表中的答案。
Good morning . I search many times before posting here . I am working on a project like a survey [Questions and Answers] I am able to get all questions in datalist , now i am searching a way to display the answers in Radio button list inside each question .
下面是页面加载
protected void Page_Load(object sender, EventArgs e)
{
string CS = ConfigurationManager.ConnectionStrings["TMConnectionString"].ConnectionString;
SqlConnection con = new SqlConnection(CS);
//Getting All Questions
SqlDataAdapter dr = new SqlDataAdapter("select * from Question ", con);
DataSet ds = new DataSet();
dr.Fill(ds, "Qs");
OuterDataList.DataSource = ds.Tables["Qs"];
OuterDataList.DataBind();
}
下面是页面主体
<body>
<form id="form1" runat="server">
<h1>Test Page</h1>
<asp:DataList ID="OuterDataList" RunAt="server">
<ItemTemplate>
<h4><%# DataBinder.Eval (Container.DataItem, "Question") %></h4>
<asp:RadioButtonList ID="RadioButtonList1" runat="server"></asp:RadioButtonList>
</ItemTemplate>
</asp:DataList>
</form>
我不知道如何绑定单选按钮列表和群组的答案。
注意：问题表，并回答表之间的共同列Question_id
i dont know how to bind radiobuttonlist and group the answers . note : the common column between Question table and Answer table is Question_id
推荐答案
Firt将类似下面的模板。
Firt will make a template like below.
<asp:DataList runat="server" ID="DataList1" RepeatDirection="Vertical"
DataKeyField="QuestionID" onitemdatabound="DataList1_ItemDataBound">
<ItemTemplate>
<table>
<tr>
<td>
<%# Eval("Question") %>
</td>
</tr>
<tr>
<td>
<asp:RadioButtonList runat="server" ID="RadioButtonList1">
</asp:RadioButtonList>
</td>
</tr>
</table>
</ItemTemplate>
这是使用DataList1_ItemDataBound可以绑定你的答案后
After that using DataList1_ItemDataBound you can bind your answers.
protected void DataList1_ItemDataBound(object sender, DataListItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item)
{
RadioButtonList RadioButtonList1 = (RadioButtonList)e.Item.FindControl("RadioButtonList1");
//Get questionID here
int QuestionID = Convert.ToInt32(DataBinder.Eval(e.Item.DataItem, "QuestionID"));
//pass Question ID to your DB and get all available options for the question
//Bind the RadiobUttonList here
}
}
