There are several ways. Here's one:
function Disable(btn) {
            btn.disabled = true;
        }
<asp:Button ID="btnSave" runat="server" Text="Button" OnClientClick="Disable(this);" />

Open in new window

The above will disable the button. If you want to prevent the button from running server-side code then you can use this:

<asp:Button ID="btnSave" runat="server" Text="Button" OnClientClick="return false;"></asp:button>

Open in new window


You can augment this system by returning the value of any function. I've found this handy in the past. For example, you could write a javascript function which asks the user for confirmation via the "confirm" javascript method. If they don't confirm then return false. It might look like this:

function foo()
{
    if (!confirm("Are you sure?"))
    {
        return false;
    }
    return true;
}

<asp:Button ID="btnSave" runat="server" Text="Button" OnClientClick="return foo();"></asp:button>

<asp:Button ID="Button1" runat="server" Text="Button"  onclientclick="disableBtn"/>

<script type="text/javascript">
    function disableBtn()
    {
    var btn= document.getElementById("<%=Button1.ClientID%>");
    btn.disabled=true;
    }
</script>



get the button id

Var button1=document.getElementById('<%= btnName.ClientID %>')
button1.style.display="block";

or

document.getElementById("button1").style.display="block";

or disable like this

btnName.Attributes.Add("onclick", "this.disabled=true;" + GetPostBackEventReference(btnName).ToString());

incase of restricting multiple click on postback
