Solution:

Try this,

 <script type="text/javascript">
    window.onload = xyz;

          function xyz() {

              document.getElementById('<%= button1.ClientID %>').click();

          }
    <script>
    <asp:TextBox ID="textbox1" runat="server" ontextchanged="textbox1_TextChanged"></asp:TextBox>

<asp:Button ID="button1" runat="server" style=" display:none;" onclick="button1_Click"  />

CodeBehind:

    protected void button1_Click(object sender, EventArgs e)
    {
        textbox1_TextChanged(null, null)
    }
    protected void textbox1_TextChanged(object sender, EventArgs e)
    {
        //your code here
    }
