Enable/Disable 选中单选按钮上的 RadDatePicker

Question

我在 RadioButton CheckedChanged 方面遇到了一些问题。我有三个单选按钮、一个 RadDatePicker、一个文本框和一个按钮。我只是想根据所选的单选按钮使用文本框中给定的值来搜索数据。我的问题是第三个单选按钮，即 "dateCreated"。我想在选择第三个单选按钮时启用 RadDatePicker。我还需要在后面的代码中执行此操作，而不是使用 Javascript 或任何其他方法。请帮助。

这是我的代码：

.aspx

<table>
    <tr>
        <td style="font-family: Calibri; font-weight: 400; font-style: normal; text-transform: none; color: #FFFFFF;" colspan="2">

        </td>

        <td class="style19" align="left" colspan="2" style="font-family: Calibri; font-weight: 400; font-style: normal; text-transform: none; color: #FFFFFF">

aspx.cs

protected void dateSearch_CheckedChanged(object sender, EventArgs e)
{
    if (dateSearch.Checked == true)
    {
        RadDatePicker2.Enabled = true;
    }

    else
    {
        RadDatePicker2.Enabled = false;
    }
}

Answer 1

尝试添加 autopostback 属性

 <asp:RadioButton ID="dateSearch" runat="server" GroupName="searchRad" Text="Date Created" oncheckedchanged="dateSearch_CheckedChanged" autopostback="true" />
