    It's likely that you'll want to wire up an event handler for your ID Textbox that will trigger when the text is changed:

    <asp:TextBox ID="txtBox1" runat="server" AutoPostBack="true" OnTextChanged="txtBox1_TextChanged" />
    

    Then, you'll just define the corresponding code-behind to perform your preloading:

    protected void txtBox1_TextChanged(object sender, EventArgs e)
    {
          // Read your ID
          var id = txtBox1.Text;
    
          // Populate your values here 
          name.Text = "...";
          mob.Text = "...";
          city.Text = "...";
    }
