Is there any way to change the value of a code behind property from JavaScript without using hidden-fields?

Code behind property means I have written a property on aspx.cs e.g. public bool IsConnected... — Utkarsh

No it could not be done without sending request to server either by postback or ajax etc. This could help you sending request to server using jquery Ajax

If you want to change the value of some server control then it is possible with javascript.

In html

<asp:TextBox id="txtName" runat="server" ></asp:TextBox>

In javascript

<script type="text/javascript>
     txtName = document.getElementById('<%= txtName.ClientId %>');
     txtName.value = "changed";
     alert(txtName.value);         
</script>

I agree, you dont will change any "code-behind property" without postback. So, assuming you dont want a full postback, ajax is the solution.

I would say AJAX is the best answer for your problem.
