recently i have been trying to create modalpopupextender and it worked just fine. then i found something that confuse me, which is the style in asp panel are set to display none

<asp:Panel ID="pnlPopup" runat="server" CssClass="modalPopup" Style="display: none">

but, when i'm running it in browser, it changed to 

<div id="pnlPopup" class="modalPopup" style="position: fixed; z-index: 10002; left: 810px; top: 186px;">

fyi, I follow the tutorial from this link

https://www.aspsnippets.com/Articles/Open-Show-ASPNet-AJAX-ModalPopupExtender-Modal-Popup-on-Page-Load-in-ASPNet.aspx

so, the question is, where is that style coming from? and when I try to put any style to replace Style="display: none", but it keep show style="position: fixed; z-index: 10002; left: 810px; top: 186px;".

Hi firdaus90,

This is the inbuilt style of ModalPopupExtender which is applied to the given PopupControlID once the popup is displayed.

I agree, here is the link: https://www.e-iceblue.com/Introduce/spire-office-for-net-free.html
