How to disable a button with asp.net after certain conditions? C#

Question

I am trying to disable a button that creates a document when the values I inserted was not recalculated. I tried something like this:

        private void EnableButton()
        {
            button.Enabled = true;
            button.Style.Remove("Opacity");
        }
        private void DisableButton()
        {
            button.Enabled = false;
            //button.Attributes.Add("disabled", "disabled"); 
            //button.Attributes.Add("disabled","true");
            button.Style.Add("Opacity", ".5");
        }

On Localhost, the 3 methods works, and it is disable and enable correctly. But on client side, even if the opacity works, the button is still clickable. I searched before asking, but could not find the solution. There is a way to verify if the button is enabled or not and disable it on asp.net file?? The button on asp.net:

<LinkButton ID="button" runat="server" Text="Save" Style="float: right"
    OnClick="button_save" ImageCssClass="button">
