我已经为这个问题尝试了几种解决方案,但没有一种能够解决问题。 基本上,我有一个员工表,用户可以选择通过更新面板动态添加员工。每个员工都被添加为 LinkButton ,此按钮将通过 ajaxToolkit:modalpopupextender 窗口> OnClick 事件,此窗口将显示员工详细信息。 问题是,当我点击员工姓名时,弹出窗口将显示但详细信息。
以下是我创建按钮并将其放入表中的代码:
LinkButton lbtn = new LinkButton();
lbtn.ID = employee_arry[i] + "_lbtn" + i;
lbtn.Text = employee_arry[i];
lbtn.Click += new EventHandler(this.employee_info);
lbtn.CausesValidation = false;
lbtn.Attributes.Add("runat", "server");
cell.Controls.Add(lbtn);
这是employee_info方法:
//the info will be pulled from the database…
public void employee_info(object sender, EventArgs e)
{
name.Text = "employee name";
dept.Text = "employee department";
jobt.Text = "employee job title";
email.Text = "employee email";
tel.Text = "employee telephone";
ModalPopupExtender1.Show();
}

这解释了动态控件的行为
你需要考虑:
如果您没有找到解决方案,这是一种方法(完整的工作示例):
<asp:ScriptManager runat="server" />
<asp:UpdatePanel ID="UpdatePanel1" runat="server" ViewStateMode="Enabled">
<ContentTemplate>
<asp:Panel runat="server" ID="myPanel">
</asp:Panel><br />
<asp:Button ID="Button1" Text="add control" runat="server" OnClick="addControl_Click" /><br />
<asp:Label ID="lblMessage" runat="server" />
</ContentTemplate>
</asp:UpdatePanel>
protected int NumberOfControls
{
get
{
if (ViewState["c"] == null)
{
return 0;
}
return int.Parse(ViewState["c"].ToString());
}
set
{
ViewState["c"] = value;
}
}
protected void addControl_Click(object sender, EventArgs e)
{
this.NumberOfControls++;
this.myPanel.Controls.Add(new Literal { Text = "<br />" });
this.myPanel.Controls.Add(this.CreateLinkButton(this.NumberOfControls));
}
protected void Page_PreLoad(object sender, EventArgs e)
{
this.CreateDynamicLinkButtons();
}
private void CreateDynamicLinkButtons()
{
for (int i = 0; i < this.NumberOfControls; i++)
{
this.myPanel.Controls.Add(new Literal { Text = "<br />" });
this.myPanel.Controls.Add(this.CreateLinkButton(i + 1));
}
}
private LinkButton CreateLinkButton(int index)
{
var l = new LinkButton { Text = "MyLink" + index.ToString(), ID = "myLinkID" + index.ToString() };
l.Click += (x, y) =>
{
this.lblMessage.Text += "<br/>ID: " + (x as LinkButton).ID;
};
return l;
}
