You Can used like

function txt_SurName()
{
var x= document.getElementById("txt_SurName");
x.value=x.value.toUpperCase();
 
}

<asp:TextBox ID="txt_SurName" runat="server" onblur="javascript:txt_SurName()" ></asp:TextBox>

Hi modify your javascript function as "Surname()" by removing the txt_ prefix.
Problem here is, your text box and the java script function has same name.

ASP.NET

<asp:textbox id="txt_SurName" runat="server" onblur="SurName()" xmlns:asp="#unknown"></asp:textbox>

HTML

<script>
function SurName()
{
var x= document.getElementById("txt_SurName");
x.value=x.value.toUpperCase();
 
}
</script>

Is it? I tried this, it works fine for me. are you control in inside the master page or panel etc..

then it may generates the different ID for text fields.

try this

JavaScript

function makeUppercase(v)
        {
          v.value=v.value.toUpperCase();
        }

ASP.NET

<asp:TextBox name="txtCandidateName" runat="server" ID="txtCandidateName"                                                                         Width="205px" onblur="makeUppercase(this)" />

use this-

XML

<script type="text/javascript" language="javascript">
function txt_SurName()
{
var x= document.getElementById("txt_SurName");
x.value=x.value.toUpperCase();

}
</script>

It work fine but you need to do the change either textbox id or function name because you gave both same.
