Since webservice is a static method, it can only call other static methods or new objects.
WebMethod:

C#

[WebMethod]
public static void ResetDate(DateTime TheNewDate)
{
    var thisPage = new Test();
    thisPage.LoadCallHistory("args");
}

Class:

C#

Class Test
{
     public void LoadCallHistory(string args)
     {
         //Do your work here
     }
}

Or
WebMethod:

C#

[WebMethod]
public static void Disp()
{
    disp();//call the static function here
}

Class:

C#

public static void disp()
{
    if (txtbox.Text != "")
    {
        txtbox.Text = "Hello world";
    }
}

Solution 2

Have a look at the following articles:
1. WebService call[^]
2. PageMethod[^]

You need to tie the onblur event with the callback/ajax call and talk to the method.
