需要帮助根据 HeaderTemplate 中的选定值单选按钮列表为 ItemTemplate 中的 gridview 中的单选按钮列表设置相同的值

Question

我的任务是创建一个 Gridview，其中用户单击 header (rblDifficulty) 上的单选按钮列表和行中的所有单选按钮列表下面的 (rblDiff) 将被设置为相同的值。我查看并修改了使用复选框和 jquery 的示例，但没有成功。希望有人能指导我这个

 <asp:GridView ID="gvData" runat="server" EmptyDataText="No Data" DataKeyNames="ID"  AllowPaging="true" PageSize ="15"
        class="" AutoGenerateColumns="False" OnPageIndexChanging="OnPaging">
        <Columns>

            <asp:TemplateField HeaderText="Name">
                <ItemTemplate>
                    <asp:Label ID="lblName" runat="server" Text='<%# Eval("Name")%>'></asp:Label>
                </ItemTemplate>
            </asp:TemplateField>
            <asp:TemplateField HeaderText="ID">
                <ItemTemplate>
                    <asp:Label ID="lblID" runat="server" Text='<%# Eval("ID")%>'></asp:Label>
                </ItemTemplate>
            </asp:TemplateField>                                  
            <asp:TemplateField HeaderText="Difficulty">
              <HeaderTemplate>
              <asp:RadioButtonList  ID="rblDifficulty"  runat="server">
                        <asp:ListItem Text="Easy" Value="0"></asp:ListItem>
                        <asp:ListItem Text="Medium" Value="Y"></asp:ListItem>
                        <asp:ListItem Text="Hard" Value="F"></asp:ListItem>
              </asp:RadioButtonList>
              </HeaderTemplate> 
                <ItemTemplate>
                    <asp:RadioButtonList ID="rblDiff" runat="server">
                        <asp:ListItem Text="Easy" Value="0"></asp:ListItem>
                        <asp:ListItem Text="Medium" Value="Y"></asp:ListItem>
                        <asp:ListItem Text="Hard" Value="F"></asp:ListItem>
                    </asp:RadioButtonList>
                </ItemTemplate>
            </asp:TemplateField>

        </Columns>
    </asp:GridView>

更新：jomsk1e 在这方面帮助了我

 Protected Sub rblDifficulty_onChanged(sender As Object, e As EventArgs)
    Dim rblDifficulty As RadioButtonList = DirectCast(gvData.HeaderRow.FindControl("rblDifficulty"), RadioButtonList)
    Dim selectedValue__1 As String = rblDifficulty.SelectedValue

    For Each row In gvData.Rows
        Dim rbl As RadioButtonList = DirectCast(row.FindControl("rblDiff"), RadioButtonList)
        rbl.SelectedValue = selectedValue__1
    Next
End Sub

试试这个，使用服务器端处理：

<asp:RadioButtonList  ID="rblDifficulty"  runat="server" AutoPostBack="true" OnSelectedIndexChanged="rblDifficulty_onChanged">
    <asp:ListItem Text="Easy" Value="0"></asp:ListItem>
    <asp:ListItem Text="Medium" Value="Y"></asp:ListItem>
    <asp:ListItem Text="Hard" Value="F"></asp:ListItem>
</asp:RadioButtonList>

protected void rblDifficulty_onChanged(object sender, EventArgs e)
{
    RadioButtonList rblDifficulty = (RadioButtonList)gvData.HeaderRow.FindControl("rblDifficulty");
    string selectedValue = rblDifficulty.SelectedValue;

    foreach (gvData row in gvData.Rows)
    {
        RadioButtonList rbl = (RadioButtonList)row.FindControl("rblDiff");
        rbl.SelectedValue = selectedvalue;
    }
}

未测试，但肯定会提示您如何操作。祝你好运！ :)
