Validating textbox using single CustomValidator Control in GridView

The below code validates all the textboxes in a Gridview using a single CustomValidator control

function isValidDate(sText) {
var reDate = /(?:0[1-9]|[12][0-9]|3[01])\/(?:0[1-9]|1[0-2])\/(?:19|20\d{2})/;
if(sText.length==0)
return false;
else
return reDate.test(sText);
}
function isValidDecimalValue(sValue)
{
var reDecimal = /^\d{1,12}(\.(\d{1,2}))?$/;
return reDecimal.test(sValue);
}

function validateForm(source, value)
{
var isXDDateError = false;
var isGrossError = false;
var objError = document.getElementById("<%= spnError.ClientID %>");
objError.innerHTML="";
isXDDateError=ValidateDateValue();
isGrossError=ValidateGross();

if(isXDDateError || isGrossError)//Both false
{
value.IsValid = false;
}
else
value.IsValid = true;
}

function ValidateGross()
{
var obj = document.getElementsByTagName("input");
var objError = document.getElementById("<%= spnError.ClientID %>");
var objSpan, isError = false;
for(i=0; i<obj.length; i++)
{
if(obj[i].name.indexOf("txtGross") > 0)
{
if(!isValidDecimalValue(obj[i].value))
{
isError = true;
if(obj[i].parentNode != null)
{
for(j=0; j < obj[i].parentNode.childNodes.length; j++)
{
objSpan = obj[i].parentNode.childNodes[j];
if( objSpan != null && objSpan.id != undefined)
{
if(objSpan.id.indexOf("spnGross") == 0)
{
objSpan.innerText = "*";
}
}
}
}
}
else
{
if(obj[i].parentNode != null)
{
for(j=0; j < obj[i].parentNode.childNodes.length; j++)
{
objSpan = obj[i].parentNode.childNodes[j];
if( objSpan != null && objSpan.id != undefined)
{
if(objSpan.id.indexOf("spnGross") == 0)
{
objSpan.innerText = "";
}
}
}
}
}
}
}
if(isError)
{
if(objError.innerHTML.length>0)
objError.innerHTML+="* Please enter a value for Gross."
else
objError.innerHTML="* Please enter a value for Gross."
objError.display="block";
}

return isError;
}
