Directly this will not work hence we will need to remove AutoPostback from TextBox and add a Fake LinkButton to make it workHTML lthtml xmlns34httpwwww3org1999xhtml34gtltheadgt    lttitlegtlttitlegt    ltscript type34textjavascript34gt        function Validateo             if ovalue  3434                 doPostBackoname 3434                        ltscriptgtltheadgtltbodygt    ltform id34form134 runat34server34gt    ltaspTextBox ID34TextBox134 runat34server34 OnTextChanged  34TextChanged34 onblur  34Validatethis34gtltaspTextBoxgt    ltaspLinkButton ID  34fake34 runat  34server34gtltaspLinkButtongt    ltformgtltbodygtlthtmlgtC protected void TextChangedobject sender EventArgs e    ResponseWrite34Your entered34  TextBox1Text
