如何使用单选按钮列表？ [英] How to use radio button list?

问题描述

嗨程序员！



我在使用单选按钮列表时遇到了困难。我在互联网上搜索了这个但我无法理解，因为我是初学者。现在，我有一个单选按钮列表，选择是和否。如果我选​​择是，它将保存到数据库为0，如果否，它将保存为1.但是当我调用包含它们的数据库时，我的下一页有我的gridview，它将显示为是和否，而不是0和1.如何做到这一点？那里有人吗？

Hi Programmers!

I am having a hard time in using the radio button list. I searched over the internet about that but I cannot understand since I am a beginner. Now, I have a radio button list with the choices of Yes and No. If I select Yes, it will save to the database as 0 and if No, it will save as 1. But when I call the database that contains them,on my next page that has my gridview, it will display as Yes and No and not 0 and 1. How to do that? Anyone there?

使用下面的代码



第一页的ASPX代码（插入）：

Use Below code

ASPX code for first page(Insertions):

<table>
            <tr>
                <td>
                    Name:
                </td>
                <td>
                    <asp:TextBox ID="txtName" runat="server"></asp:TextBox>
                </td>
            </tr>
            <tr>
                <td>
                    Age:
                </td>
                <td>
                    <asp:TextBox ID="txtAge" runat="server"></asp:TextBox>
                </td>
            </tr>
            <tr>
                <td>
                    Yes/No:
                </td>
                <td>
                    <asp:RadioButtonList ID="RadioButtonList1" runat="server">
                        <asp:ListItem Selected="False" Value="1">Yes</asp:ListItem>
                        <asp:ListItem Selected="False" Value="0">No</asp:ListItem>
                    </asp:RadioButtonList>
                </td>
            </tr>
            <tr>
                <td colspan="2">
                    <asp:Button ID="btnSave" runat="server" Text="Save" OnClick="btnSave_Click" />
                </td>
            </tr>
        </table>

CS代码：

CS CODE:

protected void btnSave_Click(object sender, EventArgs e)
    {
        SqlConnection con = new SqlConnection("Your Connection String");
        con.Open();
        SqlCommand cmd = new SqlCommand("Insert into tablename values('" + txtName.Text + "'," + txtAge.Text + "," + RadioButtonList1.SelectedValue + ")", con);
        cmd.ExecuteNonQuery();
        con.Close();
        Response.Redirect("~/DisplayGrid.aspx");
    }

显示网格页面的ASPX代码：

ASPX Code for Display grid page:

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
                <Columns>
                    <asp:BoundField HeaderText="Name" DataField="Name" />
                    <asp:BoundField HeaderText="Age" DataField="Age" />
                    <asp:TemplateField HeaderText="Yes/No">
                        <ItemTemplate>
                            <%# (Eval("Yes/No").ToString()) == "1" ? "Yes" : "No" %>
                        </ItemTemplate>
                    </asp:TemplateField>
                </Columns>
            </asp:GridView>

< br $> b $ b



CS代码：

CS CODE:

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            SqlConnection con = new SqlConnection("Your connection String");
            SqlDataAdapter da = new SqlDataAdapter("select * from tablename", con);
            DataSet ds = new DataSet();
            da.Fill(ds);
            GridView1.DataSource = ds.Tables[0];
            GridView1.DataBind();
        }
    }

这很简单。在 GridView 中，你需要使用 TemplateField 并在里面定义如下......

This is easy. In GridView, you need to use TemplateField and inside that define like below...

<asp:templatefield xmlns:asp="#unknown">
    <itemtemplate>
        <asp:RadioButtonList runat="server" ID="rblSomeName" SelectedValue='<%# Bind("FieldName") %>' RepeatDirection="Horizontal">
            <asp:ListItem Value="1" Text="No" />
            <asp:ListItem Value="0" Text="Yes" />
        </asp:RadioButtonList>
    </itemtemplate>
</asp:templatefield>

这里 FieldName 是来自数据库的字段或列的名称。

Here FieldName is the name of the field or column coming from the Database.
