我已经在 aspx 页面中而不是在 aspx.cs 中编写了此代码。
<% foreach (Employee myEmp in _empList) {
empName = myEmp.ToString(); %>
<div class="abc">
<div class="pqr">
<asp:Label Text="<% empName %>" runat="server" ID="lblEmpName"></asp:Label></label>

<div class="xyz">
<asp:CheckBox ID="chkBox" Checked="false" runat="server" />

You can do something like this:
你可以这样做：
List<user> userList = new List<user>();
foreach (user usr in userList)
{
PlaceHolder1.Controls.Add(new CheckBox()
{
ID = "cb_"+usr.UserId,
Text = usr.Name,
});
}

I think the best way to add controls dynamically to asp.net page is oninit page-event.
我认为将控件动态添加到 asp.net 页面的最佳方法是 oninit 页面事件。
you should try something like this.
你应该尝试这样的事情。
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
/*LinkButton lb = new LinkButton();
lb.ID = "lbAddFilter";
pnlFilter.Controls.Add(lb);
lb.Text = "Add Filter";
lb.Click += new EventHandler(lbAddFilter_Click);*/
// regenerate dynamically created controls
foreach ( var employee in employeeList)
{
Label myLabel = new Label();
// Set the label's Text and ID properties.
myLabel.Text = "Label" + employee.Name.ToString();
myLabel.ID = "Label" + employee.ID.ToString();
CheckBox chkbx = new CheckBox();
chkbx.ID = "CheckBox" + employee.ID.ToString();
chkbx.Text = "Label" + employee.Name.ToString();
MyPanel.Controls.Add(myLabel);
MyPanel.Controls.Add(chkbx);
}
}

I think you're just missing the :or =for the label. <%should be <%:. Use :to encode any html and avoid js injection. More infoon =vs :
我认为您只是缺少:或缺少=标签。<%应该是<%:。使用:以编码任何HTML和JS避免注射。更多信息关于=VS:
<% foreach (Employee myEmp in _empList) {
empName = myEmp.ToString(); %>
<div class="abc">
<div class="pqr">
<asp:Label Text="<%: empName %>" runat="server" ID="lblEmpName"></asp:Label>
</div>
<div class="xyz">
<asp:CheckBox ID="chkBox" Checked="false" runat="server" />
</div>
</div>
<% } %>
