Question

我的要求中有2个单选按钮。单场扰码器和多场扰码器。用户必须根据加扰要求选择“Single field scrambler”或“Multi field scrambler”单选按钮。

如果用户选择“Single field scrambler”，则应禁用以下按钮，并且必须选择加扰所需的字段。

选择配置文件
查看配置文件
修改配置文件

这是我的单选按钮列表代码

<asp:RadioButtonList ID="RadioButtonList1" runat="server" RepeatDirection="Horizontal"OnSelectedIndexChanged="RadioButtonList1_SelectedIndexChanged">
<asp:ListItem Text="Single Field Scrambler" Value="singlefieldscramble">    </asp:ListItem>
<asp:ListItem Text="Multi Field Scrambler" Value="multifieldscramble"></asp:ListItem> </asp:RadioButtonList>

当用户点击“Single Field Scrambler”时，我们如何禁用按钮。任何帮助请。

Answer 1

你可以为这样的单选按钮调用SelectedIndexChanged事件，

protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e)
{
    if(RadioButtonList1.SelectedItem.ToString()=="Single field scrambler" || RadioButtonList1.SelectedItem.ToString()=="singlefieldscrambler")
    {
       btnvcf.Enabled = false; 
       btnmcf.Enabled = false; 
       DropDownConfigFile.Enabled = false;
    }
}

您可以为单选按钮调用SelectedIndexChanged事件，如下所示：

protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgse){
    for (int i = 0; i < RadioButtonList1.Items.Count; i++)
    {
        if (RadioButtonList1.Items[i].Selected == true)
        {
            RadioButtonList2.Items[i].Selected = false;
            RadioButtonList2.Items[i].Enabled = false;
        }
        if (RadioButtonList1.Items[i].Selected != true)
        {
            RadioButtonList2.Items[i].Enabled = true;
        }
    }
}

通过单选按钮
