Have you tried thepapaibobomethod?
<asp: RadioButtonList ID = "RadioButtonList1" runat = "server">
            <asp: ListItem onclick = "set (this);"> a </ asp: ListItem>
            <asp: ListItem onclick = "set (this);"> b </ asp: ListItem>
        </ asp: RadioButtonList> </ div>

    <script>
        var id = "";
        function set (c)
        {
            
            if (c.id == id)
            {
                c.checked = false;
                id = "";
            }
            else
                id = c.id;
        }
    </ script>

I don't use radiobuttonlist very much, but I think javascript can be achieved

var obj = document.getElementById ("rblist");
obj.option [0] .checked = false;

Didn't try it, probably this is it
==============================================
If it is an aspx page, the server control should have the value of ViewState. Javascript can change the value of the html control, but the value of the view cannot be changed. JavaScript seems to have been canceled, but it is actually an illusion.

Personally think: javascript can make an effect but it is actually an illusion

Is it really unachievable?
If I couldn't find a way before get off work, I had to use two checkboxes instead. . . (But it's very troublesome)
I hope the experts can help me. . .
Thank you~~~~~~~~~~~

Work around, make another checkbox (do not select any of the above), the client makes the checkbox fully Disabled, and the server takes this value and thinks that it is not selected

PageLoad:

rblVersionSet.Items[0].Attributes.Add("onclick", "XXXXXXXXXX(this);");
rblVersionSet.Items[1].Attributes.Add("onclick", "XXXXXXXXXX(this);");

page:
<script type="javascript">
    function XXXXXXXXXX(rbt)
    {
       if (rbt.Checked==true)
           rbt.checked = false;
       else
          rbt.checked = true;
     }
</script>

That's right, I think it's really going to be realized
First use the background program to write checked = false
The second obj.option[0].checked = false; the background program reads using response.form[""], it is not necessary to use the things in ViewState

This is definitely achievable, wait, I try

It is possible to use JAVASCRTIPT, but it is troublesome. The best way is to use the new thing ATLAS, which is launched to make the page update asynchronously, and can achieve many JAVASCRIPT effects.
