Disable auto check in asp:Checkbox when click browser back button

Question

Hi,

I’m a new in asp.net. I'm creating a web forms app.
I have page 1 that displays a list of employees in asp:Table, each row contains a checkbox.
When I tick the checkbox of a row and press delete button to delete the employee, the page 1 is redirected to page 2.
But when I press the back button of browser to go back to page 1, that row I mentioned above is deleted but the checkbox of the next row (now is the first row) is automatically checked.

I have tried to find out the reason, but unfortunately I got nothing. If anyone know my issue, let me know what I can do to fix it!

Thanks and best regards,
Emily

Hi @Emily-J ,

That is: I used the site master for all of pages, when I fill out a form in the page A, then I go to page B and go back, the form is cleared.

Solution:
You could add jquery on your page to set autocomplete on the checkbox. The reason of that you don't success to work your operations is you can't get the id of the checkbox. When you put the checkbox in the ContentPlaceHolder, the id is changed. It will be 'ContentPlaceHolder1_XXX'.So, your operations don't work. You could use the type.
Just like this:

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">  
    <script src="Scripts/jquery-3.6.0.min.js"></script>  
    <script>  
        $(function () {  
            $('input[type=checkbox]').attr("autocomplete", "off");  
        })  
    </script>  
</asp:Content>

Hi @Emily-J ,
I think you could add "autocomplete="off"" on your master page's form or your checkbox.Just like this:

<form id="form1" runat="server" autocomplete="off">

Hi @Yijing Sun-MSFT ,
Thank for your reply!
I have add autocomplete=false to the form of the site master. It works. But, I’m facing another issue. That is: I used the site master for all of pages, when I fill out a form in the page A, then I go to page B and go back, the form is cleared.
I have tried to add autocomplete=false to the Checkbox: checkBox.Attributes.Add("autocomplete", "off"), but it’s not working as my expectation.

Do you know what I can do to fix it?

Thanks and best regards,
Emily
