为什么我的 asp:Checkbox 在检查时返回 false？

Question

在我的 asp:net 应用程序中，我以相同的方式设置了 2 个复选框。一个工作正常：

ASPX

<asp:CheckBox ID="uxOwnershipCheckBox" runat="server" OnCheckedChanged="uxOwnershipCheckBox_CheckedChanged" Checked="false" AutoPostBack="true"/>

C#

protected void uxOwnershipCheckBox_CheckedChanged(object sender, EventArgs e)
    {
        if (uxOwnershipCheckBox.Checked)
        {
            DataTable ownershipDT = _dtMgr.GetTicketByStatus_Everyone(uxStatusDropdownList.SelectedValue);
            uxTktGridView.DataSource = ownershipDT;
            uxTktGridView.DataBind();
            uxTicketCounter.Text = ownershipDT.Rows.Count.ToString();
        }
        else
        {
            DataTable ownershipDT = _dtMgr.GetTicketByStatus(uxStatusDropdownList.SelectedValue, Session["UserNameSession"].ToString());
            uxTktGridView.DataSource = ownershipDT;
            uxTktGridView.DataBind();
            uxTicketCounter.Text = ownershipDT.Rows.Count.ToString();
        }
    }

另一个总是将uxCloseDateCheckbox.Checked 值显示为false；即使它被检查过。因此，条件语句中的内容永远不会被解雇！我在这里做错了什么？

ASPX

<asp:CheckBox runat="server" style="padding-right:1px; float:right; margin-right:170px;" ID="uxCloseDateCheckbox" Text="Closure Date" TextAlign="Right" OnCheckedChanged="uxCloseDateCheckbox_CheckedChanged" Checked="false" AutoPostBack="true"/>

C#

protected void uxCloseDateCheckbox_CheckedChanged(object sender, EventArgs e)
    {
        if (uxOwnershipCheckBox.Checked)
        {
            DateTime dateTicketClosed = DateTime.ParseExact(uxDateTimeLocalTextbox.Text, "MM-dd-yyyy HH:mm:ss", CultureInfo.InvariantCulture);
        }
    }

Answer 1

看起来您在 _CheckChanged 方法中调用了错误的复选框。

protected void uxCloseDateCheckbox_CheckedChanged(object sender, EventArgs e)
{
    if (uxOwnershipCheckBox.Checked) //This is where your issue is..
    {
        DateTime dateTicketClosed = DateTime.ParseExact(uxDateTimeLocalTextbox.Text, "MM-dd-yyyy HH:mm:ss", CultureInfo.InvariantCulture);
    }
}

应该是：

protected void uxCloseDateCheckbox_CheckedChanged(object sender, EventArgs e)
{
    if (uxCloseDateCheckbox.Checked)
    {
        DateTime dateTicketClosed = DateTime.ParseExact(uxDateTimeLocalTextbox.Text, "MM-dd-yyyy HH:mm:ss", CultureInfo.InvariantCulture);
    }
}
