Considering that you have total textbox present in your page.

JavaScript

function getTotal()
{
    var value1 = parseFloat(document.getElementById("txt0").value);
    var value2 = parseFloat(document.getElementById("txt1").value);
    var total = document.getElementById("txtTotal");
    total.value = value1 + value2;
    
}

Hi,
You can try this:

JavaScript

function fnTotal(){
	var txt0 = $find('<%= txt0.ClientID%>');
	var txt1 = $find('<%= txt1.ClientID%>');
	var txtTotal = $find('<%= txtTotal.ClientID%>');
	txtTotal = parseFloat(txt0) + parseFloat(txt1);
}

This is working fine for me. Where you are writing your JS code? If it is in separate JS file then replace $find with document.getElementById..

        document.getElementById("<%=txt3.ClientID%>").value=   parseFloat(document.getElementById("<%=txt0.ClientID%>").value) + parseFloat(document.getElementById("<%=txt1.ClientID%>").value )
 }

Are you sure this would give proper sum? As far as I know you will have to do ParseFloat.

Try this..please search for your question first..

C#

function CalculateSum()
    {

        var Form = document.frmsum;
        var txtbx1=  Form.txt1.value;
        var txtbx2 = Form.txt2.value;
        
       var allsum = Number(txtbx1)+Number(txtbx2);
        if(!isNaN(allsum) && allsum !=Infinity)
        {
            Form.txtsum.value = allsum;
        }
        return CheckZero()
    }


on page load
 
txtsum.Attributes.Add("onblur", "return CalculateSum()");
