正确答案
1 sql结构化简单简短没有结构化

我只想将这4个答案绑定到存在于gridview中的单选按钮列表中.无法执行此操作，所以请帮助我

这是我尝试过的，

 aspx代码:
<   asp:TemplateField     ItemStyle-Horizo​​ntalAlign   ="     HeaderText   =" 在线测试！" <   ItemTemplate  > 
                        <   asp:Label     ID   ="   runat   服务器" 文本  <％#Eval(" )
 
                                                 高度  ="  16像素" 宽度   800px" 
                                                 字体大小  ="  X-Small" <  /asp:标签 > 
                        <   br    > 
                        <   asp:RadioButtonList     ID   ="     ="  服务器" 字体大小  ="  
 
                                                  RepeatDirection   =" 水平"   > 
                        <  /asp:RadioButtonList  > 
                    <  /ItemTemplate  > 
                    <   EditItemTemplate  > 
                    <   asp:TextBox     ID   ="   runat   服务器" 文本  <％#Bind(" )
 
                                                 宽度  ="  187像素" <  /asp:TextBox  > 
                    <  /EditItemTemplate  > 

<   ItemStyle     ="  左侧" <   > 
                <  /asp:TemplateField  >  

 C#代码:
受保护的 无效 GridView1_RowDataBound(对象发​​件人，GridViewRowEventArgs e)
    {
            myConnection.Open();
            cmd = 新 SqlCommand("  + employee.BranchId +  '和pn_questID ='" + txt_qsetno.Text + " ，myConnection)；
            rea1 = cmd.ExecuteReader();
            如果(rea1.Read())
            {
                RadioButtonList rbl_responses =(RadioButtonList)e.Row.Cells [ 1 ].FindControl("  RadioButtonList6")；

                如果(例如，Row.RowType == DataControlRowType.DataRow)
                {
                    rbl_responses.Items.Add(新 ListItem(Convert.ToString(rea1 [" ]))));
                    rbl_responses.Items.Add(新 ListItem(Convert.ToString(rea1 [" ]))))；
                    rbl_responses.Items.Add(新 ListItem(Convert.ToString(rea1 [" ]))))；
                    rbl_responses.Items.Add(新 ListItem(Convert.ToString(rea1 [" ]))))；
                }
            rea1.Close();
            myConnection.Close();
        } 

这不起作用，我不知道如何将4个答案字段绑定到单选按钮列表..

解决方案

希望Aspx code : <asp:TemplateField ItemStyle-HorizontalAlign="Center" HeaderText=" Online Test !"> <ItemTemplate> <asp:Label ID="lbl_que" runat="server" Text='<%# Eval("questions") %>' Height="16px" Width="800px" Font-Size="X-Small"></asp:Label> <br /> <asp:RadioButtonList ID="RadioButtonList6" runat="server" Font-Size="X-Small" RepeatDirection="Horizontal" > </asp:RadioButtonList> </ItemTemplate> <EditItemTemplate> <asp:TextBox ID="txt_que_edit" runat="server" Text='<%# Bind("questions") %>' Width="187px"></asp:TextBox> </EditItemTemplate> <ItemStyle HorizontalAlign="Left"></ItemStyle> </asp:TemplateField>

C# code :
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
            myConnection.Open();
            cmd = new SqlCommand("select option1 , option2 , option3 , option4 from online where pn_BranchID = '" + employee.BranchId + "' and pn_questID='" + txt_qsetno.Text + "' ", myConnection);
            rea1 = cmd.ExecuteReader();
            if (rea1.Read())
            {
                RadioButtonList rbl_responses = (RadioButtonList)e.Row.Cells[1].FindControl("RadioButtonList6");

                if (e.Row.RowType == DataControlRowType.DataRow)
                {
                    rbl_responses.Items.Add(new ListItem(Convert.ToString(rea1["option1"])));
                    rbl_responses.Items.Add(new ListItem(Convert.ToString(rea1["option2"])));
                    rbl_responses.Items.Add(new ListItem(Convert.ToString(rea1["option3"])));
                    rbl_responses.Items.Add(new ListItem(Convert.ToString(rea1["option4"])));
                }
            rea1.Close();
            myConnection.Close();
        }

This isn''t working, i dont know how to bind the 4 answers fields to the radiobuttonlist..
