Re: Which button was clicked to cause validation?

asp button. has server side code. has a custom validator.
The server side code does not execute until the validation has ran.
in the client side javascript code for the custom validator, can I call
any type of a function to see what event caused the page to attempt
submit hence calling all validation.
Yes it's in a form.
The two buttons are btnSearchAddress and btnSearchParcel.
For instance, when <asp:customvalidator id="val_cust_ByAddress"
runat="server" Display="None"
ClientValidationFunction="val_cust_ByAddress_ClientValidate"></asp:customvalidator>
runs it calls
function val_cust_ByAddress_ClientValidate(sender, args)
{
if (document.getElementById("txtNumber").value == "")
        {
                document.getElementById("val_cust_ByAddress").errormessage = "You
must enter a house number";
                args.IsValid = false;
                return;
        }
}

and in there I want to test if search by address was clicked or by
parcel.

 Here's some more of the code.
