我有一个复选框，用于选择＆＃34;不重要＆＃34;如果用户不想按年龄标准进行搜索。
这是aspx文件中的代码。
<asp:UpdatePanel ID="updPanel" runat="server" UpdateMode="Conditional">

<Triggers>

<asp:AsyncPostBackTrigger ControlID="txtFromAge" EventName="TextChanged" />
<asp:AsyncPostBackTrigger ControlID="chkbAge" EventName="CheckedChanged" />
</Triggers>
</asp:UpdatePanel>
在cs文件中我有以下事件。
protected void txtFromAge_TextChanged(object sender, EventArgs e)
{
txtToAge_SliderExtender.Minimum = (Convert.ToInt32(txtFromAge.Text) + 1);
}
protected void ddlSex_SelectedIndexChanged(object sender, EventArgs e)
{
if (ddlSex.SelectedItem.Text == "Male")
{
txtFromAge_SliderExtender.Minimum = 21;
}
else
{
txtFromAge_SliderExtender.Minimum = 18;
}
}
protected void chkbAge_CheckedChanged(object sender, EventArgs e)
{
txtFromAge.Enabled = !chkbAge.Checked;
txtShowFromAge.Enabled = !chkbAge.Checked;
txtToAge.Enabled = !chkbAge.Checked;
txtShowToAge.Enabled = !chkbAge.Checked;
}
我做错了什么？ 在运行上面的页面。默认情况下取消选中Checkbox chkbAge，但我使用了checked =＆＃34; true＆＃34; 。也。文本框，2为滑块，2为显示值，不会被禁用。 没有显示YSOD（黄色死亡屏幕）。
