compare text box values

[parshupooja]

Hey all I have two text boxes. I want to show message if text box1 value is not equal to textbox2

I have written this but it does not work

function ValidatePost()
{
 
     if(document.getElementById("<%=txtsign.ClientID%>").value != document.getElementById("<%=txtId.ClientID%>").value)
      {               
                 alert("-------------------------");
                 document.getElementById("<%=txtsign.ClientID%>").focus();
                 return false;
      }
}

thanks

How is this function called?

on change on of textbox1. textbox 2 gets value by itself on page load, so when user enter value in textbox 1 I want trigger validation.

thanks

So, is it something like:
[html]<input type="text" name="txtsign" id="somethingOrOther" onchange="ValidatePost()">[/html]

Just a note: please don't top-post. Thanks!

Have you checked that the IDs of the textboxes match with those used in the function? Are there any errors? If not, post your full code (if it's not too much) or a link to a test page.
