我有一个加载联系人列表的功能,并在每个联系人旁边放置一个复选框。任何获得勾选的联系人都会收到发送给他们的电子邮件。但在我的电子邮件功能中,列表总是回归零。
列表代码:
<div id="viewMenuDropFollowup" style="top:0px;right:10px; text-align: left; display:none">
<strong>Email to</strong> <a onclick="OpenEmail()" style="float:right;font-weight:bold;cursor:pointer">X</a>
<ul runat="server" id="ulCRMContacts">
</ul>
<asp:TextBox runat="server" ID="txtEmailTo" ></asp:TextBox>
<asp:LinkButton runat="server" ID="btnEmail3" CssClass="btnEmail" OnClick="btnEmail_Click" Text="Email" ToolTip="Email to selected contacts" OnClientClick="return CheckEmail()"></asp:LinkButton>
</div>
<a id="btnOpenEmail" onclick="OpenEmail()" class="EmailClass"><strong>Email</strong></a>
function OpenEmail() {
if (document.getElementById("viewMenuDropFollowup").style.display === "block") {
document.getElementById("viewMenuDropFollowup").style.display = "none";
} else {
document.getElementById("viewMenuDropFollowup").style.display = "block";
}
}
加载联系人的代码:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
LoadContacts();
}
}
protected void LoadContacts()
{
Customer c = new Customer(int.Parse(CustomerID));
foreach (Customer.CustomerContact cc in c.Contacts)
{
HtmlGenericControl li = new HtmlGenericControl("li");
CheckBox cb = new CheckBox();
cb.ID = "cbCRMContact_" + cc.ID;
cb.Checked = true;
if (!string.IsNullOrEmpty(cc.Email))
{
cb.Text = cc.Email;
cb.TextAlign = TextAlign.Right;
li.Controls.Add(cb);
ulCRMContacts.Controls.Add(li);
}
}
GetControls(ulCRMContacts.Controls);
}
我放行GetControls(ulCRMContacts.Controls);
以查看是否可以获取控件,它在这里工作正常。但是当我尝试在我的电子邮件功能中再次呼叫GetControls(ulCRMContacts.Controls);
时,它返回零。
protected void btnEmail_Click(object sender, EventArgs e)
{
if (EmailFollowup(new lookupCRMCustomerContact(Company.Current.CompanyID, int.Parse(Request.QueryString["CustID"]))))
{
DisplayMsg("Follow up has been emailed");
}
else
{
DisplayMsg("An Error Occurred sending email. Please contact Support");
}
}
public bool EmailFollowup(lookupCRMCustomerContact q)
{
GetControls(ulCRMContacts.Controls);
}
它就像ulCRMContacts
离开LoadContacts
函数时丢失了值。
答案 0 :(得分:1)
你必须(重新)在每个回发上创建动态控件,所以这不会起作用:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
LoadContacts();
}
}
删除!IsPostBack
- 检查它应该有效。如果您仍有问题,请将其移至Page_Init
,这是适当的事件。
protected void Page_Init(object sender, EventArgs e)
{
LoadContacts();
}
