Instead of this
而不是这个
ScriptManager.RegisterStartupScript(this, typeof(string), "Error", "confirm('Are u sure');", true);
use this
用这个
ScriptManager.RegisterStartupScript(this, typeof(string), "Error", "ConfirmUser('Are u sure');", true);

You may prevent the postback when use choose Cancelbutton of confirm dialog.
您可以在使用Cancel确认对话框的选择按钮时防止回发。
<asp:Button ID="Button1" runat="server"
OnClientClick="return confirm('Are you sure to populate the list?');"
Text="Button" onclick="Button1_Click" />
