I simply create a TextBox in a Web Form and set its property such as AutoPostBack=true and write a one function on its TextChanged Event in a code behind files

Here Is code For my TextBox

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
            <ContentTemplate>
                <div class="form-group col-md-12">
                     <label>Basic Salary : </label>
                    <asp:TextBox ID="txt_basic_salary" runat="server" CssClass='form-control addition'
                         placeholder="Basic Salary" TabIndex="4" AutoPostBack="True"
                         ontextchanged="txt_basic_salary_TextChanged"></asp:TextBox>
                </div>
                </ContentTemplate>
                </asp:UpdatePanel>

Here a code for my TextChanged Event in a code behind file

protected void txt_basic_salary_TextChanged(object sender, EventArgs e){
   // do something 
}

Please suggest the corrections with my above code thanks in advance for your answers
