Dear Dilip,

It does not allow you to call Javascript event and server side event at a time, this can be achieved by calling server side function from client side event.
use jquery.post() to call a server side function
http://api.jquery.com/jQuery.post/[^]
or
use pagemethods

or call java script function from server side event.
how to call javascript function .cs file[^]

This will helpful to you.

Thanks

Change your textbox event Onchange with Onblur like,

XML

<asp:TextBox ID="TextBox1" Onblur="return here()" runat="server"
AutoPostBack="True" ontextchanged="TextBox1_TextChanged"></asp:TextBox>

Onblur event does not allow you to call client side and server side events at a time. He want to execute both events at a time.

JavaScript

function here()
{
   var result = confirm("YOU WANT");
   if(result)
   {
      __doPostBack('UNIQUE NAME OF TEXT BOX', null);
   }
   else
   {
          return false;
   }
}

ASP.NET

<asp:TextBox ID="TextBox1" Onchange="return here()" runat="server"
       AutoPostBack="True" ontextchanged="TextBox1_TextChanged"></asp:TextBox>
